The Samsung SSD 850 EVO mSATA/M.2 Review
by Kristian Vättö on March 31, 2015 10:00 AM ESTATTO - Transfer Size vs Performance
I'm keeping our ATTO test around because it's a tool that can easily be run by anyone and it provides a quick look into performance scaling across multiple transfer sizes. I'm providing the results in a slightly different format because the line graphs didn't work well with multiple drives and creating the graphs was rather painful since the results had to be manually inserted cell be cell as ATTO doesn't provide a 'save as CSV' functionality.

AS-SSD Incompressible Sequential Performance
I'm also keeping AS-SSD around as it's freeware like ATTO and can be used by our readers to confirm that their drives operate properly. AS-SSD uses incompressible data for all of its transfers, so it's also a valuable tool when testing SandForce based drives that perform worse with incompressible data.

Uninteresting releases like this are the reason M.2 is having so much trouble gaining traction. Desktop users have no reason to choose the M.2 variant since they'll get similar performance out of a much more versatile SATA variant. The only obvious reason I can see to buy mSATA/M.2 versions of this drive is if you've got a laptop that can't slot a regular 2½" SATA drive. What a waste of shelf space.bricko - Tuesday, March 31, 2015 - link
These are all way slow and almost outdated. INTEL and others coming out with NVMe and PCIe 3 stuff that are 2 to 4 times as fast. Big event from INTEL listed here.http://www.pcper.com/news/General-Tech/PCPer-Live-...
Best to have an X99 mobo to make them bootable. Lots of these m.2 stuff is not bootable without lots of bios messing etc. Lots of info here

Those drives will cost upwards of 0.8$/GB. So you can't really compare those drives with these ones.Not to mention, they would be HHHL cards instead of M.2 and they use 20nm NAND which is almost 2 generations old.

Many of the m.2 sticks run very hot and manu are insertin g them into adapter cards to fit in pcie slot.Here is link to one....but its been removed from server and being sold before the consumer version is out. The cost is enormous because no other supply yet, but should be out to consumer in day or 2.

here is m.2 adapter card with heat sink for the samsung 941 ssd drive to put into pcie slot

but again, these early ones are difficult to make bootable, need x99 mobo and to get the nvme you need windows 8.1 which has native driver.

While I'm under NDA for that announcement, what I can tell you is that there's no M.2 coming tomorrow.bricko - Wednesday, April 1, 2015 - link
Good explanation on how and what these new m.2 drives are and what you need to get them to work.http://www.tomshardware.com/answers/id-2468965/ssd...

I was so hoping to see a m.2 42mm option from Samsung...WackyDan - Tuesday, March 31, 2015 - link
Same here... So these aren't available in 42mm?
