Samsung 840 Evo incredibly slow in MacBook Pro 2011

I just got a brand new 250GB Samsung 840 Evo SSD and put it in my MacBook Pro. The drive is incredibly slow. OS X install took hours, and it takes over a minute to boot up. Even small tasks like clicking a button take several seconds to process. I have enabled TRIM through terminal (which took about an hour) and still no better. Is this something that can be fix or should I get an RMA# from NewEgg?

jeffturner24,
older firmware revisions of the 840 EVO are known to be problematic on Macs. You can download the latest firmware package for it (and an instructional PDF) from this Samsung page; with this package, you can burn a bootable DVD from which the latest firmware revision can be installed.
Another possibility is that you might have a faulty internal SATA cable. If you connect your SSD externally and boot from it then, and it runs at normal SSD speeds, but it remains incredibly slow when booting from it internally, that could point to a problem with your internal SATA cable. (Hard disks are more tolerant of a faulty internal SATA cable than SSDs are.)
If neither step above resolves the issue, then you should arrange an exchange with Newegg.

Samsung 840 EVO SSD slow in macbook Pro

Hello Everybody.
Some months ago I got from amazon the a 250 Gb ssd, samsung 840 Evo.
Usign Black Magic I was impressed to see read/write speed about 450 MB/s.
Lately, running Black Magic Speed test, I noticed that the results drop down to 30 MB/s.
I just updated the ssd firmware and the result are almost the same (i think is going a lil better, but still dropping to 30-40 MB/s.
I know there are some threads about this, but didnt get to have clear is this normal, a faulty piece or what?
Some more info:
Trim Enabler ON.
Free space from 50Gb-120 Gb (the results are almost the same)
Macbook Pro 15" mid 2012, 2,3 GHz ,i7, 8GB ram.
ssd firmware EXT0BB6Q (just updated)
Even more info:
Right now I have just Chrome opened, and I'm running some tests.
The very first result go up to 480 Read and over 500 Write.
Restarting the test sometimes the first results in Write dont go higher than 260 MB/s.
Within 10-15 sec the write speed drops to 180 Write, then up again to 230-260 MB/s.
Waiting 1-2 min It drops down to 100, then 80 to reach 30 MB/s (all this is Write speed, Read is almost constant at 480-500 MB/s)
Stress 5GB.

Grant,
I have been using the drive as a system drive for one year without enabling the TRIM, which I did yesterday. Are you suggesting that enabling TRIM does not remove the garbage filled blocks? Should I format the drive and proceed with a fresh install, or will the blocks clean with regular use?
Put simply, when something is deleted on a HD, the OS understands that the space is now free and can be written to. SSD's do not understand that so the pages from which the file was deleted are considered still full of good stuff. The link I provided goes into some detail about what's involved in erasing SSD blocks so deleted files get moved along with the current files in the SSD erasure dance.
TRIM is the way the OS informs the SSD that the space occupied by the deleted file really can be erased, and the SSD then acts on it. However, your SSD hasn't been directly notified about the year's worth of deleted data because TRIM wasn't activated to do it. The SSD's Garbage Collection process will get to that space eventually but it won't be as efficient as if TRIM was there to help.
But since all the SSD's blocks have a finite life span, the less they're exercised by erasing, formatting and reinstalling stuff, the longer the SSD should last.

Samsung SSD 840 EVO not detected in MacBook Pro 2012.

Hello,
In January I had a problem with my computer where it would overheat, the battery would die quickly, and the overall computer speed was slower than a turtle for even the most basic functions. I brought my computer to a MacMan retailer and they fixed the issue. I then got my MBP back and it worked fine for about a month. It then repeated the same symptoms it had before I got it fixed. I talked to my roommate and did some research and ended up purchasing the Samsung SSD 840 EVO 250gb to replace my Hard Drive.
I transferred all my data to the new SSD and then installed the SSD to the internal bay where the hard drive sits without any problems. After the SSD was in place I booted up the computer and I got a "flashing folder with question mark." The SSD was not internally recognized by my computer. I then tried to put my Hard Drive back in to see if it would be recognized and it was not. However, both the SSD and Hard Drive are externally recognized via USB enclosure. I have been working on this for a couple days and am getting frustrated.
I have tried a number of fixes I thought would surely work. I reformatted the SSD to the appropriate Mac format that every forum and website recommend: Mac OS Extended (Journaled) and that does not work. I have reinstalled OS X Yosemite, I have tried updating the SSD Firmware through USB. Nothing has worked yet. I have tried using Apple's internet recovery system and neither drive is recognized when inside the computer. My best assumption but least favorable is the Cable within the MacBook Pro that connects to the Hard Drive/SSD is faulty. I fear that it may be faulty since now neither the SSD or Hard Drive is detected when they are installed in the MacBook Pro, only when external.
Can anyone please help me figure out what could be wrong? If you need more information just ask and I will do my best to answer them to your satisfaction. Anyone input, conclusion, or direction would be greatly appreciated!
Thank You for your time and knowledge!

You have already defined the probable cause, the internal SATA cable. For verification, take the MBP to an Apple store genius bar for a FREE evaluation. It is not an expensive repair, even if done by Apple.
Ciao.

Replacing my HDD in my Early 2011 Macbook Pro...Trying to decide between Samsung 840 EVO 250 gb and Crucial M500 240 gb. Samsung is faster but less "mac-friendly". Should I opt for the Crucial due to the "mac-friendliness"?

I have a S.M.A.R.T error on my current Hitachi drive that came with me Early 2011 Macbook pro. Want to upgrade to SSD.
Trying to decide between Samsung 840 EVO 250gb and Crucial M500 240gb, at this gb range, the Samsung is faster and uses less wattage....ONE PROBLEM...I have read many user experiences that note it is much less mac-friendly...
The software samsung offers is not IOS compatible and some report lower than expected speeds after installation...Also apparently the RAPID MODE of the drive, the fastest drive mode is nonexistant when installed on a Macbook pro?
Should I opt for the slower and more power cosuming Crucial M500 240gb SSD because it is more Mac-friendly? Does anyone have a Samsung 840 EVO 250 gb SSD installed in their macbook pro? What has been your experience?
Thanks ahead of time!
Resoure: http://www.tomshardware.com/reviews/crucial-m500-1tb-ssd,3551.html

I decided against the Evo as there are too many Mac users that have had issues with slow speed on them. Even without these, the main speed that Samsung states for the Evo comes form turbo Write which is a PC only feature as is software dependent.
I'm sorry but Crucials M500 is simply too slow compared to modern drives to be recomended. Read speed is ok, but the write is far too slow for the price.
I've used and installed both a Samsung 840 basic and a Samsung 840 Pro in 2 separate Mac books! and currently have the 840 Pro in my own MacBook Pro and it comes very highly recomended. It's all but the fastest Sata III drive you can buy - A few OCZ drives just edge it but the difference is negligible. Samsung by far have the best reliability though when it comes to SSD's. I've been getting 520Mb/s easily on mine consistently, and without getting a MacBook with a PCIe drive you won't get a faster more reliable drive.
I really would recommend nothing else.

Samsung 840 Evo vs 850 Pro for thinkpad w530

I want to purchase a 250 gb samsung ssd drive for my w530. My specs:
Lenovo Thinkpad W530
I7 3520M @ 2.90 GHz (2 Cores 4 Threads)
8 Gb Ram
Nvidia Quadro Q1000M
I am a mechanical engineer at work, and use this computer for learning new things on my free time. I will be using it to study solidworks simulation, catia, and maybe inventor or creo. I wil use it to understand principles of features and technologies, not for heavy duty freaquent calculations, or constant work with large assemblies. This computer would be too slow for these tasks anyhow.
I would appreciate your advice between these two discs: Samsung 850 Pro and 840 Evo.
Pro has a few GB more space, which actually makes no difference. The considered field is the other performance parameters: on certain tasks 850 Pro is a little, and in other tasks - much faster, according to benchmarks, e.g.:
http://ssd.userbenchmark.com/Compare/Samsung-850-Pro-256GB-vs-Samsung-840-Evo-250GB/2385vs1594
Basically it is a new generation ssd drive, having much faster write speed.
But my mentioned computer is for personal use, is not too fast, and is already 2 years old. Based on my setup and tasks, do you think Pro series will have a performance advantage on my system? Pro is a little more expensive, and I am not sure if I can feel the difference in this computer, maybe you have some advice on this?
Thank you for your ideas

Yes, all of those tasks are highly CPU/GPU intensive, not disk intensive. Where you would see a difference is large scale file transfers and/or when the drive is almost full. The EVO would slow down to below the speeds of a standard hdd when it is almost full due to the nature of its memory (which is why it is cheaper in the first place), while the pro would not as much (it still would - all SSDs do - but not as bad as the EVO).
However, the EVO is kind of designed to account for this, which is why it is only 250 GB. The extra 6 GB is still in the disk, but it is set aside so that you can't fill it up. The rest of the EVOs follow this, too - 512 reduced to 500, 1024 reduced to 1000 - to protect the user from completely destroying its R/W speeds.
Note that this is still not enough to prevent degradation, and that you should try to keep at least 23-25 GB free on a 256 GB drive for maximum performance. The best method is to just leave the last 25 GB unpartitioned.

MSI GT70 0NC 494 - Samsung 840 Evo Problem

I recently brought a Samsung 840 Evo 500GB to replace the WD Black HDD on my MSI GT70-0NC-494 laptop. OS is Windows 8. Im going type out pretty much how I ended up to where I am right now in hopes that maybe someone could catch where I went wrong.
So here's the story:
The cloning process went smoothly and I was able to load the OS from the SSD without any problems. Then I immediately updated the firmware and I set the optimizations using the Magician software.
I ran CrystalDiskMark and had speeds around ~300MB for both read and writes on the sequential test. Thought that my speeds were kind of slow when comparing them to the others I've seen. AHCI is on. I know my laptop has a SATA 2 and SATA 3 slot but I did plug the SSD in the SATA 3. SATA 3 connection is confirmed through Intel RST application and Samsung Magician. The speed is just not around the ballpark of what everyone is getting.
Ok, let's see the speeds with Rapid Mode so I turned on Rapid Mode and restarted. Then I get a "Start PXE over IPv6/4" message which then leads to the BIOS screen. Turn off laptop, turn it on, and get the same message. Turn off laptop again, turn it on, and the OS loads this time.
I thought that was weird but whatever I got to the OS, I thought. Open up Task Manager to see how Rapid Mode affects my RAM capacity since my regular usage already puts me ~1.5GB below max. 1.9GB shows up on RAM. Thought I'd be starting closer to 3GB. Then again, Im not entirely sure on how Rapid Mode works so whatever. Run the benchmark test through Magician software.
(This pic was from after I reinstalled Win 8 but the performance drop was similar)
Ok, , the read speeds is now garbage. Did the test on CrystalDiskMark and it shows similar results. It was late at night and Im feeling tired so I keep my laptop idle overnight to see if that would help. Nope, read speeds are still garbage. Surprisingly enough, CrystalDiskMark would show write speeds for sequential hitting ~1000MB/s so it seems that the write process is somewhat fine. The read process seems like it's broken.
So I turn off Rapid Mode and see if that fixes my read speeds. Restart. Get BSOD on startup. Turned laptop on and off multiple times to see if anything works but no avail. Thankfully I created a set of recovery disks 2 days ago so I immediately run that now. I was planning to restore the OS to factory install anyways so its fine.
OS is restored. At this point Im scared of installing the Samsung Magician software so I make a restore point. This time I want to see what happens if I install the software and run Rapid Mode through Win 8.1.
Seems like I can't just upgrade to 8.1 without installing a bunch of updates first so I do that. I got impatient so I went ahead and installed Magician and did the optimizations. CrystalDiskMark showed ~300MB/s for read and ~400MB/s for write. Ran the Magician benchmark and it produced the light blue bars on the screenshot above.
Let's try Rapid Mode now. Turn Rapid Mode on, restart, and I am again greeted with the "Start PXE over IPv6/4" message before hitting the BIOS. Now Im telling myself that I messed up again. Turned off the laptop and turned it on. OS is back. Awesome, only 1 try.
Did benchmarks on Magician which again showed that my read speeds were garbage (dark blue bars). I'm not even going to touch Rapid Mode for fear of having to reinstall the OS again. So now Im trying to upgrade to Win 8.1 and see if that fixes something.
Download 8.1, restart, I get some BSOD message with the code "0xC1900101 - 0X20017", restart through BIOS, and I get an error saying that 8.1 failed and Im being reverted to 8. Desktop loads up, I check Magician and my 840 Evo doesnt even appear on the drop down list. The software even says Rapid Mode is disabled even though I can see the Rapid Mode service through task manager.
Now Im just running tests, and restarting the laptop to install additional Windows updates. Upgrade to Windows 8.1 actually went through this time. After the update, Magician now says that Rapid Mode is on and my SSD again appears to be selectable. Read speeds seems to have gotten a *tiny bit* better but it is still extremely low.
Decided to say screw it, disabled Rapid Mode, restarted, again with the "Start PXE over IPv6/4". Turn off laptop, turn on, surprisingly no BSOD saying my system is forever broken. Now Im trying to see if I could salvage the performance back through messing with the settings so I followed most of the advice on another website.
Now it seems that the write speed is consistently good, but again the read speeds are absolutely horrid. I used AS-SSD for the benchmark instead of CrystalDiskMark this time.
And that is where I am right now. I am very sorry that the post is ridiculously long. I've been constantly looking around the internets to see if anyone has the same problem as me and I couldnt find a solution. I wanted to somewhat be detailed with my process so I can know whether this problem is the software or the MSI hardware. Or if the problem is with my specific SSD and that I'd have to RMA it.

How did you go about installing Windows?
It looks like the first time you used some software that ended up cloning it from the HDD to the SSD. That's a no-no in general, and I'd never trust it to work well.
Then the next time, you say you restored it. But you don't say if that was from the SSD/HDD or from recovery media that you had generated.
I'll be perfectly honest, I'd only trust installing from Recovery media when it comes to installing a new drive.
I'd say to do that. Install from Recovery media and see if that fixes the problem.
I will also say that a number of users have had issues with the Samsung 840 drives. Most of them were using the Samsung 840 Pro drives, not the EVO's, but just something to keep in mind. They were only able to get them to operate at SATA2 speeds.

Samsung 840 EVO Series MZ-7TE1T0 1TB

Can the Samsung 840 EVO Series MZ-7TE1T0 1TB be used in place of the internal hard disk in a MacBook Pro 17" Late 2011?
Thanks,
Richard

The samsung is compatible with your laptop, no problem with that. But your plan of installing 2 disks has some disadvantages.
First of all, there is no space for two 2.5'' disks inside the T430s (70mm disks are referred to as 2.5''). You will have to remove the DVD-RW and install a caddy. Inside the caddy you can install one of the disks. It's not difficult or expensive but you will lose the DVD drive.
Second, why would you buy a 1TB SSD for storage??? It would cost you sometning like 600 euros while for 80 euros you could buy any 1TB mechanical disk and it would be more than fast enough for storage. SSDs are meant for the operating system and programs and there they make a big difference. But anyway, if you have lots of money to burn, why not?
There is another solution though, much more sensible i think. Your T430s can accept mSata SSDs. They come in the form of add-on cards, much like ram modules, and they are installed in the interior of the laptop. Take a look here and here. You can buy a 256GB mSata SSD for around 200 euros and install your OS and programs there, leaving the 2.5" compartment available to install a big 1TB mechanical disk for storage. This way you get to keep your DVD drive as well.
My 2 cents..

MSI GX660R with intel motherboard and compatibility with Samsung 840 EVO SSD

Hi
Im am new to this forum, so I apologize in advance if this post is in the wrong section.
I am considering to replace the hard drive in my MSI GX660R with a Samsung 840 EVO 250 gb ssd, since it has the best benchmark ratings and are very afordable. My laptop has an Intel motherboard with an i7 core processor.
My question in relation to the upgrade is, whether the laptop is compatible with that excact ssd. I plan to run it in AHCI mode, since I have bad expirience with loss of data under RAID. If i chose to run the extra HDD as a secondary drive, it will therefore still be under AHCI.
Can anyone refer me to some sort of compatibility list, or tell me if the above mentioned drive is compatible? I havent been able to find out myself, and MSI is farily difficult to get in contact with.
Any help is appreciated.

Yes, your early 2013 Retina model uses 6.0 Gbps SATA but it's not a standard mSATA connection. You could upgrade using Transcend's JetFlash -> http://www.transcend-info.com/apple/jetdrive/ - to space up to 960GB, however.

Ssd samsung 840 evo

Hi (sorry for my english, I'm a french customer)
I have replace my superdrive (dvd) by a ssd samsung 840 evo (MZ-7TE500)
When I run the mac, the ssd doesn't appear in the "finder".
In the Disk utility, the ssd appear but I can't do nothing.
An error message appear when I try to make a partition:
Partition failed with the error:
Wiping volume data to prevent future accidental probing failed.
I do not know what to do!
the problem just might be the sata cable?
it is perhaps not quite electrically powered?
If I switch the HDD and SSD at boot mac, he going to embark on the HDD or SSD?
if it does not work and I presents the HDD in place, it will work there as before?
thank you very much for your help.

François,
do you have a SATA-to-USB or SATA-to-FireWire adapter, to allow you to access your SSD externally? If so, are you able to format it externally without problems?
Note that earlier versions of the Samsung 840 EVO firmware were known to be problematic on some Macs. You can download its latest firmware (for burning onto a bootable DVD) from the Samsung firmware page.

Samsung 840 EVO 250G installed in HP Pavilion dv7t-4100

With help from Banhien and newmodeus, I installed a Samsung 840 EVO 250G in my laptop. I got the bare disk from Samsung and a caddy and cable from newmodeus. I installed the SSD in the secondary bay and cloned the primary hard drive onto the SSD. Then I switched positions, so the SSD became the boot disk. The Samsung software worked well (about 34 minutes to clone 93G). I had moved all the data to a backup so it would not get cloned.
Boot time is about 15 seconds (Windows 7 Home Premium 64 bit). Everything is much faster, including web pages loading. I use Pro Tools 11 on this machine and that program is a collosal resource hog. It now moves very quickly, which should assist the creative process.
Thanks Banhien for the referral to newmodeus, which had just the right products for my needs.

You should be able to go as high as 2TB.
I also own a,(Older), DV7 notebook which has dual drive capability.
I bought my caddy from the place recommended and got everything needed including screws !
I matched the capacity in mine with an exact same hard drive and have never had a problem.
Minor battery life noticable but that was it.
Your system BIOS is what will hold you back from say a 3TB drive.
You can go to HP site and check the specs on your model and find out for 100 % sure.

I would recommend doing what I did and match the drive exactly.
Good day !

IMac early 2008 Yosemite SSD Samsung 840 Evo= Kernel panic

Hi ,
I have an iMac (24-inch, Early 2008) with 2,8 GHz Intel Core 2 Duo processor and 2GB RAM. When Yosemite came out i've traded the iMac Superdrive with an SSD Samsung 840 Evo. I've installed OS X Yosemite on the SSD but my Mac keep crashing on boot and the third-part application doesn't work very well. I've tried reinstalling it, SMC reset, PRAM reset, Disk and Permissions repair and various clean installation but nothing changed. When I turn on my Mac on the apple logo appears the Kernel panic and restarts well. I tried to install the OS in the old HD and it work fine but is really slow. Help me please and sorry for my english

I haven't changed the original RAM.
This is the Kernel Panic but the BSD process change every time.

Z87-G45 Gaming not able to install Win7 x64 with Samsung 840 EVO

I have a brand new:
i5 4570
MSI Z87-G45 Gaming
250GB Samsung 840 EVO
1x 8GB Corsair ValueRam DDR3 1600
I got everything hooked up properly, but I am not able to install Win7 x64 through an USB pen drive (Kingston Datatravel 32GB USB3) I have a proper official and Legit MSDN ISO, formatted by the Win7 USB tool from MS itself.
Note that i do not have an optical device (DVD) installed so I cannot use it 'the old way'.
Bios settings are okay, everything is recognized
USB Legacy - Kingston Datatraveler
HDD Legacy - Samsung 840 EVO
Win7 setup loads properly; but before I can select the Harddrive / SSD to install Win7 on I get prompted that additional (3rd party) drivers are needed to proceed. The volume is not recognized. This happens 9 out of 10 times. In the 10% cases I do get the option to format the SSD and/or create partitions. However, installation fails after all, cannot load or find file ...
What I've tried so far:
Switch out the SATA cables and power cables
Switch through the various SATA ports on the MB 1 through 6
Tried UEFI and UEFI/Legacy (UEFI doesn't seem to work at all)
Update UEFI to V 1.50
All the above result in the case mentioned.
I have succesfully installed the SSD in an other PC, using the same pen drive and ISO and it worked like a charme, thus ruling out that the SSD, pen drive or image is corrupt.
Even when I switched out the SSD after Win7 setup has succesfully copied, unpacked and installed all the files (doing this on the other machine where it works like a charm). Then switching it to the MSI Z87...it fails; starting the setup procedure right from the start, like nothing was ever written on the SSD...
Finally i turned to Win8, and guess what, it installed without any glitches on the MSI Z87
What am I missing here, I would really want to install Win7 instead of Win8
Forgot to enable / disable something in the UEFI? I really don't know, google doesn't give much information on this specific problem (SSD is recognized properly by the BIOS / UEFI as far as I can tell)
The only thing I have not tried out so far is updating the Samsung SSD firmware to the 1.0 version which has been release 3 days ago...
Any clues, tips, hunches??

Did you disable Secure Boot in the BIOS? If not, then Win7 won't load.
Hmmm not sure, thanks for the reply, will have to look into that later today!
I didn't change it from the default setting I think, unless it is part of the Win8 features in the UEFI. All where disabled by default, and I kept them disabled.
Where is Secure Boot listed in the UEFI, and any idea wether it is enabled by default?
::EDIT::
Found it in some screenshots, I cannot recall from the top of my head wether it was enabled or disabled, allthough my gutt feeling says it already is disabled.

Hi alangium,
Welcome to the Support Communities!
Resetting your computer's PRAM should restore your Macbook Pro's screen appearance.

This article may provide some information about your Mini DisplayPort to AVI adapter. Have you tried to connect a different VGA monitor to your Macbook to see if you get the same results?

18. What is the maximum resolution available for use with the Apple Mini DisplayPort to VGA adapter?
The resolution available with the Apple Mini DisplayPort to VGA Adapter is 1920 x 1200. VGA displays that use higher refresh rates (such as 85 Hz) at resolutions of 1600 x 1200 or greater may not generate video properly until you lower the refresh rate.

How can I detect displays?
If the detect displays option is not available, hold down the Option key while you are in the Display pane.
How do I select additional resolutions on my display?
You can use the Display pane of System Preferences to specify how your display works. Not all options appear for all display models. By default the best resolution for your display will already be selected in System Preferences.
To select a different resolution, use the Scaled option. Some additional resolutions may be available when you hold the Option button.
I hope this information helps ....
