Samsung 840 EVO M.2 vs 870 EVO Plus M.2

[stockhausen]

I am running a system based on a Gigabyte Z97X-SLI motherboard which I am (reluctantly, finally) moving over from Windows 7 to Windows 10.
My current System "disk" is a 120 GB Samsung 840 EVO SSD (no longer available).
I am considering replacing it with a larger and faster 250 GB Samsung 970 EVO Plus M.2 SSD.
The former (SSD) uses a SATA-III 6.0 Gb/s ACS2 interface.
I believe that the EVO 970 M.2 SSD uses a PCIe 3.0 (x4) interface.
The Z97X-SLI spec says that it offers M.2 support for SATA & PCIe.
It doesn't appear to mention what version of PCIe it offers.

Any suggestions as to whether the Gigabyte Z97X-SLI will benefit from the improved performance that the Samsung 970 Plus M.2 SSD can offer?

Just been reading some reviews of the Samsung 970 EVO Plus M.2. Quite apart from some crafty beggar managing to substitute 3 pieces of cut card for the SSD in a few cases, it seems that they may have a rather severe overheating problem!

I'm guessing you mean the 970 EVO Plus and not 870? I have a 970 EVO Plus and have yet to experience any issues with overheating. That didn't stop me buying a heatsink for it anyway however, as I've always been a believer in trying to keep my components reasonably cool. . . .

Thanks for that. Yes, I was referring to the 970 EVO Plus; in fact both the content of my post and the title show a few errors!

Interesting about the cooling. I had a look last night at cooling for 2280 M.2 cards and encountered (amongst other cooling solutions) a "Dual Port M.2 PCIe/SATA SSD Adapter Card with Heatsink" which could allow RAID 1 mirroring and sounds interesting.

If you're looking at the same accessories that I was, that card is probably PCIe M2 on one slot, and SATA M2 on the other, which are two completely different types of M2 drive.

Presumably with the SATA drive having worse performance figures than the M.2 drive and probably not allowing "mirroring" (RAID 1)?

I'll check

I suspected as much, I guess I will just have to continue making regular "image" copies of my system disk (and restoring occasionally).

My motherboard is a Gigabyte Z97X-SLI, it offers RAID which I would assume is (sort of) carried out in hardware since it is presumably not dependent on any particular OS?
