USB 2.0 data transfer : slow rates

Hello.
What is the average speed for copying data (let's say video avi files) to flash drives. I am detecting an average of 3.0 MB/sec. Is not this VERY slow for USB 2.0?
I am using a Lenovo T400 with Windows 7 64 bits.
T400 (2767-AK3)

If you are really intent on investigating, there are more things to look at:
1. Is anything else connected to any USB port at the same time you are transferring?
2. Dig in the device manager, find host controller (may show up as multiples), open "properties", "advanced", see
if you can find bandwidth information and reserved values (may be hardware dependent).
3. Is it possible that transfer rates are reported differently? Real rates may differ from what you see (how do you check?)

Does I pad usb adapter allow data transfer and storage.

I hear that it "sneezes" at external hard drives so am wondering if the camera connection kit allows any write or only read?

Presently the iPad can only import photos and and videos that are placed in a "DCIM" folder in the root direction of a FAT 16 or 32 formated device. It is not clear if the device can be a hard disc. I have seen videos where a hard disc did not work. I had a n old 4 gb flash drive that did not work since it drew too much power (got error message).

Not able to connect N82 to pc in data transfer mod...

I am not able to connect N82 in data transfer mode( other modes are working fine) though i installed latest connectivity cable driver for N82. It says that it could not find any suitable driver(after search cd provided and online).
My current firmware version of N82(RM-313) is 10.0.046. Operating system is Windows Vista. Will the firmware update fix the problem or I have to contact customer care center?
Thank you for your support.

Hi mlhpr
If phone is set to 'data transfer" mode on user interface and USB plugged into PC N82 behaves as a Windows USB mass storage device and you are saying that Windows Vista can't recognize this?
Ya thats is what the problem is. As you said the phone was to behave like USB pendrive in data transfer mode but i am getting this error.
:I first connected the N82 with cable Nokia CA-101 provided with handset and selected the data transfer mode. Then the windows(Vista) icon would appear in task bar showing windows is installing the driver. Then a window pops up saying driver not found and requests permission to search online for driver. When I choose search online for suitable driver, it searches for a while and says no driver found. (net is working prefectly fine). The icon disappears from the bar and phone is inaccessible from windows explorer. But USB indicator on mobile screen is active until i disconnect using mobile connectivity settings.
Actually i wanted this mode for installing the Nokia Maps which requires the phone to be in data transfer mode.

My nokia n 95 data transfer problems

hi guys i just got this n 95 a week ago and i am trying to transfer video files to my nokia phone
but when i connect it to usb and select "data transfer mode"
its giving me a message on my phone
"USB data transfer mode activated. Mass memory may not be used during this time"
and i am not able to save files to my phone
when i save it its showivg me on my computer when i open "Removable disk D" drive my files are in phone like the vedeo file but when i disconnect the phone and go to my videos its empty
i just dontknow what should i do should i return the phone or what
please someone help me
thanks

Hi,
maybe format of video files you've copied to the device memory are not readable by phone. Did you convert it using Nokia Video Manager (part of Nokia PC Suite) on 3gp or mp4.
And if you connect phone with PC use PC Suite mode instead of the USB. You will have acces to all yours phone memories
Cheers

New mac pro recognises usb 2.0 as 1.0 - super slow data transfer!

updated my new mac pro 3.5 GHz 6-core intel xeon E5 to mac OS 10.9.2 today.
all periphals (standalone hubs, hubs in monitors, harddisks) are now recognised not as is (USB 2.0) but as USB 1.0 (ie transfer rate 12 Mbit/s), no matter whether they are plugged into a port of the mac pro directly or thru a hub. i do not get anything done anymore!
any advice how to get back to USB 2.0?
thank you!

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.

How can I check the data transfer rate of my FW800 port

I have an iMac 2.4 20 inch (MB323LL/A) with a Lacie external rugged hard drive (320 GB). I have attached it using my FW800 port with the cable supplied with the drive.
It seems slow to me so I was wondering if there is any way to see what the current data transfer is for a backup in progress. Of course it should be 800Mbps but is it really moving at that speed ? How can I tell what speed it is transferring at ? Can I use the same method for USB ports too ?

When you move a large file, you are more likely to see a sustained transfer rate than a small file. Small files have to be individually read/write back and forth, thus slows the actual transfer rate down. If you are moving any file up to 4 GB and probably over 1 MB you'll see more realistic transfer rates. Furthermore your hard drive access time, and RPM figures into the equation too, as well as how much RAM you have. 800Mbps works out to 100 Megabytes per second under ideal conditions.

MyRIO memory, data transfer and clock rate

Hi
I am trying to do some computations on a previously obtained file sampled at 100Msps using myRIO module. I have some doubts regarding the same. There are mainly two doubts, one regarding data transfer and other regarding clock rate.
1. Currently, I access my file (size 50 MB) from my development computer hard drive in FPGA through DMA FIFO, taking one block consisting of around 5500 points at a time. I have been running the VI in emulation mode for the time being. I was able to transfer through DMA from host, but it is very slow (i can see each point being transferred!!). The timer connected in while loop in FPGA says 2 ticks for each loop, but the data transfer is taking long. There could be two reasons for this, one being that the serial cable used is the problem, the DMA happens fast but the update as seen to the user is slower, the second being that the timer is not recording the time for data trasfer. Which one could be the reason?
If I put the file in the myRIO module, I will have to compile it each and every time, but does it behave the same way as I did before with dev PC(will the DMA transfer be faster)? And here too, do I need to put the file in the USB stick? My MAX says that there is 293 MB of primary disk free space in the module. I am not able to see this space at all. If I put my file in this memory, will the data transfer be faster? That is, can I use any static memory in the board (>50MB) to put my file? or can I use any data transfer method other than FIFO? This forum (http://forums.ni.com/t5/Academic-Hardware-Products-ELVIS/myRIO-Compile-Error/td-p/2709721/highlight/... discusses this issue, but I would like to know the speed of the transfer too.
2. The data in the file is sampled at 100Msps. The filter blocks inside FPGA ask to specify the FPGA clock rate and sampling rate, i created a 200MHz derived clock and mentioned the same, gave sampling rate as 100Msps, but the filter is giving zero results. Do these blocks work with derived clock rates? or is it the property of SCTL alone?
Thanks a lot
Arya

Hi Sam
Thanks for the quick reply. I will keep the terminology in mind. I am trying analyse the data file (each of the 5500 samples corresponds to a single frame of data) by doing some intensive signal processing algorithms on each frame, then average the results and disply it.
I tried putting the file on the RT target, both using a USB stick and using the RT target internal memory. I thought I will write back the delay time for each loop after the transfer has occured completely, to a text tile in the system. I ran the code my making an exe for both the USB stick and RT target internal memory methods; and compiling using the FPGA emulater in the dev PC VI. (A screenshot of the last method is attached, the same is used for both the other methods with minor modifications. )To my surprise, all three of them gave 13 ms as the delay. I certainly expect the transfer from RT internal memory faster than USB and the one from the dev PC to be the slowest. I will work more on the same and try to figure out why this is happening so.
When I transferred the data file (50MB) into the RT flash memory, the MAX shows 50MB decrease in the free physical memory but only 20MB decrease in the primary disk free space. Why is this so? Could you please tell me the differences between them? I did not get any useful online resources when I searched.
Meanwhile, the other doubt still persists, is it possible to run filter blocks with the derived clock rates? Can we specify clock rates like 200MHz and sampling rates like 100Msps in the filter configuration window? I tried, but obtained zero results.
Thanks and regards
Arya

Difference in data transfer rates between winXP and Linux server?

Hello all,
I am using a winXP laptop to act as my server (all usb external hard drives are connected to it) but the data transfer rates can be really slow. Is Linux faster in that regard? Can a Linux based server provide faster data transfer rates?
Thanks for any help.
Bmora96

Linux cannot make hardware go any faster - so if WinXP and its drivers are making optimal use of those USB drives and the USB data transfer pipe, Linux will not make it faster. (but installing Linux and going Tux are always excellent ideas that need no real reason either ;-) )
Real question you should be asking is if using a notebook in a server role is wise thing to do?

Disk data transfer rate - iMac 2013

Good morning Apple fellows
First of all, sorry for my troubled English speaking, I'll do my best to explain the issue I'm having in the best way possible.
Yesterday I finally received my new iMac (I'm a proud Apple user since 2006), the machine has these specifications: 16 GB Ram, i7 processor, nVidia GT 780M, and a SSD drive of 1TB of capacity.
Under Mavericks everything runs smooth and fine, no issues at all, just perfect, the fastest machine I've ever had. Unfortunately, I had to install Windows 7 via Bootcamp (I'm a mechanical engineer and I use Autodesk Inventor to do my stuff).
After completing the installation of the Microsoft OS, I instantly noticed some laggy performance while running Windows: I installed as asked all the Bootcamp drivers with the USB pendrive that I prepared, but both the startup of the system and the normal use were a bit slow, even slower than my old '09 iMac.
In order to understand what the problem was, I ran the system performance test included in Windows: all the ratings I have are maxed out at 7.9 (7.9 is the top I think), in exception of the "Disk Data Transfer Rate", that is 5.9. As far as I remember, this value is typical for a mechanical disk drive, not for an SSD drive supported with PCIe connections.
Does anybody here got a similar issue? Is there any driver package that I have to install in addition to the Bootcamp drivers?
Thanks in advance

That is because the WEI uses your boot disk as the default device to measure performance, and, for instance, a Velociraptor 10 K disk, does not score more than 5.9. The story changes when the test is run on other disks, like my array:
However, this measurement is totally worthless in real life. You should look at practical benchmarks like PPBM5 Benchmark

Internal Disk to Disk Data Transfer Speed Very Slow

I have a G5 Xserve running Tiger with all updates applied that has recently started experiencing very slow Drive to Drive Data transfer speeds.
When transferring data from one drive to another ( Internal to Internal, Internal to USB, Internal, Internal to FW, USB to USB or any other combination of the three ) we only are getting about 2GB / hr transfer speeds.
I initially thought the internal drive was going bad. I tested the drive and found some minor header issues etc... that were able to be repaired so I replace the internal boot drive
I tested and immediately got the same issue.
I also tried booting from a FW drive and I got the same issue.
If I connect to the server over the ethernet network, I get what I would expect to be typical data transfer rates of about 20GB+ / hr. Much higher than the internal rates and I am copying data from the same internal drives so I really don't think the drive is the issue.
I called AppleCare and discussed the issue with them. They said it sounded like a controller issue so I purchased a replacement MLB from them. After replacing the drive data transfer speeds jumped back to normal for about a day maybe two.
Now we are back to experiencing slow data transfer speeds internally ( 2GB / hr ) and normal transfer speeds ( 20GB+ / hr ) over the network.
Any ideas on what might be causing the problem would be appreciated

As suggested, do check for other I/O load on the spindles. And check for general system load.
I don't know of a good GUI in-built I/O monitor here (and particularly for Tiger Server), though there is iopending and DTrace and Apple-provided [performance scripts|http://support.apple.com/kb/HT1992] with Leopard and Leopard Server. top would show you busy processes.
Also look for memory errors and memory constraints and check for anything interesting in the contents of the system logs.
The next spot after the controllers (and it's usually my first "hardware" stop for these sorts of cases, and usually before swapping the motherboard) are the disks that are involved, and whatever widgets are in the PCI slots. Loose cables, bad cables, and spindle-swaps. Yes, disks can sometimes slow down like this, and that's not usually a Good Thing. I know you think this isn't the disks, but that's one of the remaining common hardware factors. And don't presume any SMART disk monitoring has predictive value; SMART can miss a number of these cases.
(Sometimes you have to use the classic "field service" technique of swapping parts and of shutting down software pieces until the problem goes away. Then work from there.)
And the other question is around how much time and effort should be spent on this Xserve G5 box; whether you're now in the market for a replacement G5 box or a newer Intel Xserve box as a more cost-effective solution.

Slow Airport Extreme 5th Gen Data Transfer

Airport Extreme Slow Data Transfer
When transferring files between PC – Nas, Nas – PC, & PC – PC my speeds are extremely slow (1.3 – 3.3mbps). Files range in size from 350mbps to 4gb. Here is my set-up:
Acer Aspire 5532 Win 7 x64 (internal 5ghz nic)
Toshiba Toshiba Satellite C655 Ubuntu 12.04 (internal 5ghz nic)
Gateway GT5418E Win 7 x64 (USB 2ghz nic)
Iomega 2TB Nas

2nd Generation Airport Extreme 5ghz extended network
It doesn’t seem to make a difference if I am using the extended network or sitting 5 feet from the primary (either band) with the extended disabled. I ran a LAN Speed test: averaging 12 – 16mbps write and 20+ read. Any advice would be helpful!
Thanks!

Data transfer rate Airport Extreme

which is the data transfer rate of the USB port in the Airport Extreme (4ta. Generation)...???
The HDD installed in that port, reads and writes very slow

I executed the test and I have a rate of data transfer of 1.9 escrtura of Mb/s and 2.7 reading Mb/s…. this is very under… What I can do.?
I even reinitiated the Airport and itself with the problem. I directly tested with the ports of iMac, and have DRT of 25.8 and 18.4 Mb/s
Ok, I am assuming that your measurements are in Mega Bytes per Second (MB/s) and not Mega Bits per Second (Mb/s). Even so, I would agree that you are getting low data transfer rates.
What is the make and model of the USB HDD that you have attached to the AirPort Extreme? Is it formatted in HFS+ or FAT32?
Also, the 25.8 & 18.4 readings when you have this drive attached directly is a bit low as well. I would expect something more like: 35 MB/s (read) & 25 MB/s (write) for a USB 2.0-connected HDD.

I just checked my BIOS and my current setting is set at IDE although it also mentions that the default should be AHCI. Currently I have a dual boot of Windows 7 (need it for Tax software) and Arch
So I guess, when I get the new HDD, I will first set it to AHCI and then install the OSes on it. See if NCQ helps any, and if not I will turn it back and re-install (if I have to). I am planning to have Windows only in virtualbox in the new drive.
Anyhoo, while I was in the BIOS I found two things which I had questions about :
1) Under Onboard Devices --> Integrated NIC , my setting is currently set at "On w/PXE" and it says the default should be just "On". Would it be ok to change it back to On since its a single machine and its not booting an OS on any server. I just don't want to have to re-install anything now since I will be doing that in the new HDD.
2) How would I know whether my BIOS would support a 64 bit OS in Virtualbox? I checked some setting under Virtualization, but they weren't very clear.
I will edit this post and let you know exactly what settings were present under the Virtualization sub-section.

Data transfer very slow on mac pro!! mac H/W unable to fit specifications.

Hi,
I am installinginternal disks on the quad mac pro and the transfer ratet in the mac are very slow!!!
the disks are: barracuda 7200.10 disks, 500 GB. Sta II 300, max ST3500630AS firmware 3.AAE . throughput:300mb.jumpred off to get the 300.
MAC tells that the QUAD MAC Pro equipment (2x2.66ghz dualcore intel xeon) comes with a 3.Gigabit specification/ 300MB/sec. (Intel ESB2 AHCI, speed: 3.0 Gigabit. AHCI version 1.10 supported)...
And the benchmarks of the disk ST3500630AS show maximum 80MB/sec and a minimin of 37.3MB/sec, average 63.1 MB/sec. (anandtech tests).
According to seagate.com the maximum sustained data transfer rate:78MB/s
but in the mac the reallity is different: I am getting a transfer rate of 22MB/sec!!!!! . with out any application running and only making copy of the files!!!!
that means that the mac is only providing only 1/3 of the expected transfer rate for the disks..
so, is there a way that the MAC Pro gets all the normal transfer rate for those disks???
Is the Quad MAC Pro hardware unable to get the maximum throughput of the disks???
It seems that the mac is unable to get also the average transfer rate of those disks.. how to correct it???
thanks a lot
Alberto
ps. just for fun: I am getting a faster transfer rate from an old power pc ,and old pc, and firewire 400 and old ide disks!!! (36MB/seg!!!)

Yup.
BThe latest Mac Pro are better, so if you have a new or 2 month old unit, Seagate should work, though I think there should be later firmware.
Some would say those drives take the cake or woRSe.
http://www.barefeats.com/hard91.html
SEAGATE PUZZLES
+Firmware version 3.AEE or later solves the slow sustained large block write speed issue for a single 7200.10 inside the Mac Pro.+
+The remaining performance issue is slow small random read speeds for one, two, three or four drives. No matter how many drives you configure in RAID 0 sets, the average random read speed for combined block sizes from 64K to 1024K is less than 30MB/s (based on QuickBench 3 testing).+
+Until Seagate fixes this, we can't recommend the 7200.10 series as the ideal boot drive for the Mac Pro (or Power Mac).+

[Solved]Computer slow down and freeze during data transfer syncing

Hello,
Everytime I make a data transfer, my computer slow down, and sometimes freeze during a few seconds, work for a fraction of seconds and freeze again. I don"t understand why.
As an example, here is a bench of files i transfered during a syncing with Grsync
It took about 12h to sync 64Gb.
I've read a lot of topics talking about this problem but nothing works. I tried to switch off the SWAP and setting the vm.dirty_ratio and vm.background_dirty_ratio but nothing works.
I'm making the trasfer between two Western Digital USB 2.0 external hard drive in NTFS.
Does anyone know how to fix this?
Thanks in advance

It seems it was beacause one of my external hard drive was about to die. I performed the same operation with 2 Western Digital external hard drive 1To USB3 and it works perfectly.
