Hello Guys.
I know in regular PCIe slots gen 2 and 3 are compatible with each other.
So I assume with M.2 it would be similar.
However I would like to know, whether or not I'm going to loose performance or not.
I was going to get the Samsung SM951 NVME SSD for 127€ with M.2 PCIe 3.0 x4 (32Gb/s).
My mainboard is a ASRock A88M-G/3.1 with an M.2 Socket PCIe Gen2 x4 (20GB/s)
Question is, does it matter?
Thanks for your help.
Probably fine, but PCI-e SSDs are generally going to be a waste O money. I guess you'd be getting it pretty cheap though at 127, normally you'd get twice as much sata SSD storage for the same price. How are ya getting the drive so cheap anyways?
Not sure if that motherboard supports NVMe drives but yes M.2 gen 3 is compatible with M.2 gen 2 as long as the motherboard supports the drive technology.
lol, while reading this post the ssd just sold out.... It was at a german site called "mindfactory". It's pretty well known here.
But isn't the read speed of 1.4gb/s worth the extra price?
Musta been a really crazy sale then
Still 480gb Sandisk ultra II Sata SSD, pretty much maxes out that interface I think, possibly the best overall for the money
129 EU

I have an SM951 on a Z97 board running at full Pcie 3.0 x4, and yes. Hell yes, it is worth it. You can get a lot more storage if you go with sata but you don't realize how slow even a sata ssd feels until you've ran a pcie ssd for a boot drive.
That drive is TLC nand, so no not good. TLC is far less reliable then MLC and drastically worse then SLC. He should be looking for MLC drives (with the exception of the 850 and 840 evo's).
I have two recommendations. The first the kingston 480GB savage, which is an MLC drive with a Phison controller. I put one of these in my mom's laptop when the old drive died, and its ran like a champ. My second recommendation is the Samsung 850 evo. Its a TLC drive, but Samsung TLC is different because it is stacked nand. This has proven to make TLC reliable whereas other normal TLC drives like the aforementioned SanDisk are plagued with failures.

You have to be careful when you're looking at choosing an NVME drive, M.2 or PCIE should support it as a basic drive but not all motherboards support NVME as a boot drive.
I'm planning on using the board soon and been doing as much research on M.2 as I can, basically ASRock's site doesn't say that this board supports NVME as boot drive, or not, but it some boards say specifically that they do.
The manual list a few M.2 drives it supports. Basically it's safer to get AHCI type SM951 or the Kingston Predator.
I'm gonna wait a bit for a good sale or, hopefully, more drives to come out.
