"The older firmware problems have been well documented and fixed.

http://mspoweruser.com/samsung-re...rformance/

"It fixes the gradual degradation of read performance of Samsung PM851 SSD drives which was caused by an issue with the voltage decay compensation algorithm, which lead to excessive read retries on old data. After the update, the performance seems to be increasing from 321 MB/sec to 503 MB/Sec."

Also note the SSD in the test at that link is the exact same part number as this SSD.

We have also confirmed with Samsung that the firmware on these drives, EXT42M0Q fixes the issue with the voltage decay compensation algorithm."

MyDigitalDiscount

-NO, not fixed. They problem still exists as how those chips work. they just correct for it by rewriting the data occasionally.

Yes! EXT42M0Q is the latest firmware for PM851 OEM version of 840EVO SSD mSATA .
However, EXT43B6Q is the latest firmware for non-OEM version of 840EVO SSD mSATA.(EXT42B6Q is the fisrt firmware update, which is equivalent to EXT42M0Q.)
The Samsung Magician 4.9 Performance Optimization Advance tab, which rewrites/rearranges the data to at least temporarily fixes reading of old data, only works for EXT43B6Q instead of EXT42M0Q (credits to laptopquestions).
In other words, you won't be able to use Magician for PM851. U can use DiskFresh, but it worked only for 2 weeks before ssd is slow again.

SURFACE OWNERS
This is a direct link to a non-public hotfix [microsoft.com] for the problem on Microsoft Suface Pro machines:
http://hotfixv4.microsoft.com/Sur...64_zip.exe
It will update the firmware from EXT41M0Q to EXT42M0Q and install a program that "optimizes" the drive.

For surface owners thinking about swapping out this drive for something different - fuggedaboudit! The Surface Pro 3 is just about as non user serviceable as you can get. The Pro 4 is similar.

Just a heads up that this is the OEM version of the Samsung 840 EVO which is known to have degradation problems with usage: http://www.techspot.com/article/9...gradation/

My advice is to stay clear of the 840 EVO drives.

We have confirmed with Samsung that the firmware on these drives, EXT42M0Q fixes the issue with the voltage decay compensation algorithm. Purchase these drives with confidence.

P.S. My wife has a surface pro iii with one of these with this exact FW and it runs great. Also if you have any reservations leave 10% free or run a self OP program. These drives are great we had 2 running in a RAID case at over 600MB/sec r/w.
I'd stay away. These are essentially Samsung 840 EVO drives that slow down over time. I don't think the firmware to fix this issue was ever released for these drives. See this thread:

Is it interchangeable with a M.2 2242 slot?

Unfortunately no, even though speeds are the same. Wish I needed this as I miss mSATA prices.

Given the price, this would be great to use in mSATA/2.5 adapter for some nasty badass speed.

It is not as it is slightly longer and wider than a 42mm drive and the pins don't match up. I'm sure there is an adapter out there but your computer probably would not have enough room for it.

There is a firmware update they pushed out. They even reference it in the techspot review with a link to an update benchmark. I ordered one. $100 for a 512 msata drive is a steal. Was hesitant til I saw there are firmware updates for this issue

Get a 2x mSATA 2.5" Raid adapter then you are talking silly speeds like NVMe speedsSmilie

You have a link for a high performer? I might be on board.

As I am a vendor rep we are not allowed to post any links but we just bought a generic one to test it out with and got over 600MB/sec read write and the random speeds were just amazing as well. BTW USB 3.0 can go faster than 600MB/sec we tried it in a raid box for USB 3.0 and got well over 600MB/sec R/W on that as well. I previously thought USB 3.00 had a 600mb/sec sealing.

M.2 is the successor to the Mini-PCIE slot into which this mSATA Samsung drive plugs. I have not seen Mini-PCIE (mSATA) slots on motherboards since ivy bridge.

M.2 also interfaces with both PCI-E directly (x2 or x4), and SATA. You can buy both types of SSDs and they both click into M.2, but they communicating with the CPU in inherently different ways.

Of course, the fastest solution would be an M.2 PCI-E drive. Anything which utilizes SATA in any way (SATA6, mSATA, SATA-M.2) will be limited to 600megs/second.
