Slow flash drives

I use 32Gb flash drives for storage. One recently has started running very slowly - is this a functiuon of flash drives or is there something I can do you re-invigorate it?

If possible you could try formatting it. Firstly head to disk utility (you can search for it in spotlight search). Secondly click on the disk you want to format and click format, make sure Mac OS journaled (or extended) is selected as the option. Good luck!

Do not buy the USB3 PNY Turbo Flash Drive!

I have highly recommended the USB 3 PNY Turbo Flash Drive in the recent past as a fantastic Read storage device. Well do not buy it. PNY drastically changed the memory chips inside without changing the model number and now it is a terrible device for holding your media for editing operations.
Thanks to Randall for making me aware of this problem. I now have 4 of the older good type and 3 bum ones. Here are two Windows 8 transfer plots of a large AVI file from the USB 3 Flash drive to a Samsung 840 Pro on my laptop. The first one is the original one that I purchased last July with a file transfer rate of 185 MB/s, and the second plot is the lousy performance of 120 MB/sec.of one of the last devices purchased in November.
The new ones are usable but nowhere as desirable as the 1st generation. I checked several websites and see that they no longer advertise the old faster specifications. Also I have tested all my devices and scoring is consistent and very repeatable. Now, that I know it is possible, I will start looking for a new vender that give the great read rate ideal for laptop editing. Of course it is not as convenient as a USB 3 Flash drive but my Vantec NexStar 6G USB 3 SSD enclosure with a Samsung 840 Pro drive has a Read rate of 250 MB/second.

Bill,
It looks like you may have to settle for a slower flash drive at this price point for the foreseeable future: Every single one of the USB 3.0 flash drives at this capacity point that delivers at least the same level of read performance as the original PNY Turbo costs much more money than the PNY. ($150-ish for a SanDisk Extreme Pro 128GB USB 3.0 flash drive, anyone?)
With that said, the PNY Turbo 3.0 is only intended to compete with the slower USB 3.0 flash drives such as the SanDisk Ultra USB 3.0 drive (whose maximum read speed is only 100 MB/sec even in its largest-capacity 128GB version).

MacBook Pro running slow after USB flash drive

I mount a Kingston USB flash drive to my 30 days old MacBook Pro running Lion 10.7.4
My Mac didn't recognize, so I inserted another one and it did recognize it.
And I notice my mac was running slow, some task that I did the day before (illustrator cs6) were really fast.
But after that USB flash drive it went slow, I thought it was and error and reebot it, also cleaning out the Cache and other stuff with CleanMyMac.
But it continues to run slow.
Please if someone knows what I can do I will appreciate it.

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Flash drives and SD/microsd heats up and slow while transferring files, is this normal?

My new macbook pro heats up my flash drives/sdhc/microsd while transferring files. I thought it was just the Micro sd itself (using MicroUSB adapter) but when plugging in a differnt flash drive it too was getting hot and quickly heating up. I also thought it is pretty slow for a Class 10, which i dont think it is the it could be the flash memory, is there something i am doing wrong? its using mac os x journaled format. This also happens when i plug it in the sdxc slot. Any ideas?

I had another apparently hung Time Machine backup today.
Starting Dashboard did NOT fix it this time. However, after what seemed like a long time (probably 5-10 minutes) it apparently freed up on its own and completed the backup normally. This makes it appear my previous result was just "coincidence".
There were a few error messages thrown into the Console this time by the "backupd" process -- An "Error(-43)" while apparently attempting to find a path to a file with a "null" name.
Despite that, the backup seems to have copied what it was supposed to copy.

USB copying to flash Drive very slow suddenly!

any help would be appreciated and plz give me some advice on how to handle the new keyboard! and anything mac
thanks !

I have been experiencing the same problem with an Intel iMac 17" here. I use a variety of external powered hard drives and flash drives via USB. I notice last month that transfer speeds had dropped considerably. That and the fact it had been a year or so since I had last reinstalled prompted me to completely wipe out and reinstall the OS (10.5).
After a complete erase and install, with all current updates applied as of this date, the problem still persists. For example, I have my iTunes library on an external self-powered hard drive. Playing songs is fine, but video is unwatchable. Just now, I attempted to copy a movie file (approx. 700 mb) to a USB flash drive. The reported transfer time was 5 hours!! This is true across the board for me, no matter how the configuration is, be it devices connected directly to the machine's own USB ports or through a powered hub, having self-power or powered through the port.
This problem has only started for me in the last couple of months, with regular updates applied as they came out. Resetting the SMC has also not worked.

Download to flash drive very slow

Downloading to a USB flash drive (2 attempted: Sandisk Cruzer and Kingston, both with plenty to free space) has always been slower than other transfers (ie, HD to HD, HD to Firewire HD), but suddenly transfer rates plummeted from a few minutes for 50 MB to well over an hour. I tried restarting alone, ran Applejack on a second restart, nothing. Folders downloaded contain jpg images, pdfs, and MS doc and docx files, nothing unusual, and pretty much the exact same folders that were already on the drive. I was updating them to include a few current files. Incidentally, after none of the above worked, I tried deleting one of the folders I was replacing (and emptying the trash) before transferring the folder to the USB drive, with no success.
This has never been an issue on this same Power Mac g5 running the same everything and using the same 2 flash drives (I keep them as supplemental backups of current data).
Anybody have an idea why the transfer rate would slow this much?
thanks

Growl has been a big problem in the past a few times.

USB Flash Drive Transfer Speed Extremely Slow

Aloha,
I have a 32GB Verbatim USB Flash Drive. The speed is 480Mb/sec. My mac is a MacPro running 10.5.8.
For some reason the transfer speeds from the computer to the flash drive is really slow. 2gb file takes 3 hours to transfer. I tested the flash drive on another MacPro and the transfer speeds were normal.
I have reformatted the flash drive (as FAT32) but it doesn't seem to help that much.
Anyone have this problem before and know whats up? This thing is basically unusable right now...

I just used Quickbench to test the speeds on my USB drive. About 38mbs Read, 32mbs Write. Pretty poor numbers. How that works out to your own I don't know, maybe you could do the math to find out.
Good luck.

Late 2008 mbp - installed new ssd - trying to boot from snow leopard iso on flash drive - says 'cannot install mac os on this computer'

Hello -
I just installed a new M500 Crucial ssd in my late 2008 mbp - everything was working fine on old hard drive (running snow leopard) but was getting slow and wanted to upgrade - i lost my snow leopard disk when moving from hawaii so i found an iso online - using a flash drive i partitioned the disk and made the bootable image on flash drive - formatted as extended/journaled - switched out the hard drives - plugged in the flash drive - started the comp - held option - install begins to boot - choose language - all is fine - choose english - next step window pops up saying 'cannot install os on this computer' - click on utility but all options are greyed out - disk util is greyed out - only options it gives is to start from backup or restart - real confused here - all help appreciated - thanks in advance and happy new year!

Snow Leopard comes in discs only. The USB drive may be a counterfeit and/or corrupt. There are two options for you:
Get replacement original OSX installation disks from Apple customer service. Have your MBP serial number ready and there is a charge.
Or two, purchase a Snow Leopard disk from the Apple online store:

How to Back-Up an iPhoto Library to a Flash Drive in Mountain Lion

I have been backing up my entire iPhoto library (about 34GB) to a flash drive every month for the last couple of years.
I tried to do it last night, after upgrading to Mountain Lion, and could not complete the backup. I tried several times, and the same thing happened each time - the first 190MB or so were transferred very quickly, then the pace slowed until finally, after 225.1 MB were transferred, I got an error message: "The operation can’t be completed because an item with the name “iPhoto Library” already exists."
I tried trashing the partial file on the flash drive, renaming the partial file, using Disk Repair - same exact thing happens. Always stopping after 225.1 MB.
I have 5 years of photos on my iMac, and am freaked out about losing them. Anyone have any ideas?

That'll be the problem then.
iPhoto needs to have the Library sitting on disk formatted Mac OS Extended (Journaled). Users with the Library sitting on disks otherwise formatted regularly report issues including, but not limited to, importing, saving edits and sharing the photos.
Regards
TD

Clean Install: from Recovery Disk vs. from USB Flash Drive

Planning to do a clean install on my MBP running Yosemite. Have come across two ways of doing this: From the Recovery Disk or from a USB Flash Drive.
If the clean install can be done by using the Recovery Disk, why would you do one using a USB drive?
Is there any benefit to the USB drive method? Basically I want to know if one way is preferable over the other.
I want to make sure I wipe everything, as my machine's been slow/glitchy since OS X Yosemite was first installed/updated; I'm also not sure if I have picked up anything else along the way. (I'm pretty careful with my browsing/downloading, but I like to be sure.)
Thanks for any help.

The advantage of the USB drive is that you do not need an Internet connection. If you do not have a solid Internet connection or the Apple servers are down, you may be dead in the water. The only possible advantage of using the recovery option is that the latest version of the given OSX will be available. That may not be the same as what is installed on the USB drive.
Before you use either option, make certain that you have your data backed up.
Ciao.

USB Flash Drive Issue On iMac - 1.1 on iMac, 2.0 on any other Mac

I have a Core i7 27" Late 2009 iMac.
I just noticed this issue today.
I have a couple of Patriot XPorter XT USB Flash drives that I use among my Macs to transfer big files around.
Hooking one of the 8GB flash drives to my iMac, the one listed above, it shows the device operating at USB 1.1 speeds, whether it's in a powered hub, or one of the 4 USB ports in the back of the machine. This was odd, because this was the first time it had ever done this. I only noticed this due to the painfully slow transfer rate the Finder was reporting to me. Restarting the iMac, cold starting the iMac, resetting permissions, PRAM and SMC did nothing. I thought it was a bum drive.
So I grabbed a 16GB flash drive (same brand and model family, different capacity) and it works perfectly fine on the iMac at USB 2.0 speeds. Hmm...
So I boot the iMac into Win 7 Ultimate x64. Both drives are listed at USB 2.0 speeds. Something is definitely afoot here.
To make sure I'm not losing my sanity, I grab my MacBook Pro and test the drives in there. Both drives are listed at USB 2.0 speeds.
I then run to my Mac Pro. Both drives are listed at USB 2.0 speeds.
Did something go wonky on my iMac?
Machine specs (for comparison above)
iMac 27" i7 2.8GHz - 16GB RAM
MacBook Pro 15" Core 2 Duo 2.4GHz - 4GB RAM
Mac Pro Xeon 2.66GHz - 12GB RAM

I think that you are just running into a communication blip between the thumb drive and the controller for the USB ports on your iMac. It is obviously reading the 8 GB drive as older and slower and is assigning that lessor priority to the bus serving the drive.
Have you tried attaching the drive directly to the iMac with no other device connected to a USB port? If it is the same, then I doubt there is anything that you can do, that is going to be the way the USB controller reads this thumb drive.

How do I use iPhoto on a flash drive?

I recently transferred my entire 30 GB iPhoto library on to a 64 GB flash drive and then deleted the whole library on my laptop. However, when I now plug in my flash drive to use iPhoto it runs EXTREMELY slow. Are there any solutions to make it run faster or any different methods to store a large iPhoto library off of a computer with quick access to it? thanks.

It will run much faster on your computer's hard drive because flash drives are slow. You could instead put it on a portable hard drive in a USB enclosure.

Flash drive + speed issue

My macbook is running slow as ever. it freezes every now and then.
The biggest problem is that it takes more than 5 minutes to detect a flash drive.
i am using 10.5.8 and i have 1gig RAM. i repaired all the disk permission but that did not slove the issue. i am fed up force shutting down my macbook. please help.
thankyou.

Try reinstalling OS X:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
Also, add more RAM to your computer. 1 GB is not enough. You should use 2 GBs or more (if your model supports it.) Also be sure you maintain ample free space on your hard drive - 10 GBs or 15% of the hard drive's capacity whichever is greater.

HELP Adobe flash drive update BUG?? Big Problem

I bought a 13 inch MacBook Air in August 2014.
OS X Maverick, Version 10.9.4. 4 GB memory, 256GB storage.
I have been using Safari to see lecture videos from Echo360, and they have been working well despite the slow internet of the country.
Just until two days ago, everything had been working fine, until a Adobe Flash Driver Update popped up on my screen.
At first I ignored it (b/c I usually dont care about using the latest versions; the lecture videos had been working perfectly)
but it kept popping up so I clicked update.
The next day, my mac kept losing connection to internet every 1-3 minutes, such as "resolving host" messages.
The videos kept crashing and I had to re open the page, refreshing wouldnt work. about 15 times for a 50 minute video.
I erased the Flash Driver.plugin from my internet plug-ins in the library, and the internet came back alive.
I was guessing the "updated" plugins were eating up my internet/browser...
So then I downloaded chrome so I wouldnt have to manually use adobe anymore,
and now, the videos keep freezing at random moments at about 5-10 minute intervals. Now that the internet is back alive, i just have to refresh the page, which still takes forever to load...fortunately the browsers dont crash anymore...
Right then, I completely disposed anything related to adobe flash drive. I still have Adobe pdf which works great.
But even after, it kept freezing...
Maybe I was thinking this is normal when watching videos on chrome b/c the plug ins are not manually stored in my mac?
If not, what is causing the freezing of the videos on google chrome? (i dont think my mac is losing internet connection anymore every second like yesterday)
Is there any way to fix it? Is it from yesterday's history of downloading the "update"?
I just want to be able to watch my lecture videos like I normally did the past two weeks, before I downloaded the "update"
and now I am afraid that downloading adobe might crash my internet/browsers again.
It took me several hours to come to erasing the "updated" plug ins as I am fairly a noob in computers.
I spent a lot of time and researched a lot up till 5AM in the morning just last night.
and I have exams coming up next week... I would really want this to be resolved.
Should I try downloading adobe from its actual website and see what happens?
If yes, which versions would you recommend?
Yesterday when I checked after the update, it stated the most current Adobe 15.
If this contains bugs for mavericks, I would rather do older versions.
I do not know which version I was using before the "update" when everything worked perfectly.
Thanks for reading all this
I know I am all over the place; Im just very frustrated and desperate as not knowing what to do....
I just want my mac to work like before I clicked on the "update"
Any help will be greatly appreciated
Thank you

You probably installed some kind of malware pretending to be a Flash update. That's very common.
1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can read it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of the script have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report what happened. No harm will be done.
12. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Flash drive for Macbook?

Really want to install one these in my Macbook once I can soucre one, does anyone know if it would fit ok.?

MacBook White 2GHz Mac OS X (10.4.8)

I would guess it's going to be quite a few years before flash drives supplant hard drives if ever. What probably will happen soon is we'll see hybrid systems. 32 gigs isn't a lot, that's true, but it's plenty for storing the OS and frequently used applications, meaning the HD won't have to spin up, draining battery power and slowing things down. The HD would eventually be relegated to archiving material no used on a regular basis.
