Ultra M.2 interface

post #1 of 7
Thread Starter 
Recently I been seeing the latest interface M.2 go yet again to another level, with speeds up to 32Gbs! Im wondering how they do it, and if you really could take advantage of such data transfers which looks pretty promising on paper..

They're saying that their design connects directly to the CPU and bypassing the chipset. I'd first look at some tests and then what really matters! Which is the performance of the board vs. other boards.

Apparently Tom's round up a few months back shows that it's the Smart Buy...so I guess its hard evidence that it works smile.gif

So i tested Ultra M.2 on X99, where it makes much more sense since CPU bandwidth isn't being affected if you use PCi-E 3.0 lanes for storage. On Z97 if you do this you lose the ability to run 16x on a GPU, unless there is some extra chip added to expand the CPU's lanes. On X99 since there are 40 PCi-E lanes on the top tier CPUs, you can still run GPUs in most configurations without bandwidth limitations.

There are like 2 types of 4x M.2 slots. One type if PCI-E 3.0 which produced 32Gbps, the other way to do it is PCi-E 2.0 and it produces 20Gbps.

There is only really one M.2 drive that can even take advantage of 4x lanes and that is the Samsung XP941 and I got that to 900+ MB/s on both the PCi-E 2.0 and PCi-E 3.0 based X99 boards, but only the sequential read even takes advantage of it.

The rest of the M.2 drives are limited to like 500MB/s to 600MB/s for sequential read and they wont really benefit from anything above normal M.2 standards.

ASRock X99 OC Formula (4x PCi-E 3.0=Ultra M.2): 985MB/s
GIGABYTE X99-SOC Force(4x PCi-E 2.0 = Turbo M.2): 975MB/s
GIGABYTE Z97X-Gaming G1(2x PCi-E 2.0 = Normal M.2): 765MB/s

THose are from memory so I might be a bit off, but you get the gist.

BTW I did have issues booting M.2 on the C7Z97-OCE but other boards were fine for the most part. BTW M.2 drives get hot and I am told that is normal, but damn it was freaking hot.

Cool, thanks!

Hmmm...if its too hot, you might need to look at the cooling in the system or do you think its the M.2 drives itself?

I think its designed to run that way, its just not what we are used too, you know? You don't expect your SSD to get hot. However that Samsung is one of the fastest drives out there.

I dunno, best to check with the manufacturer...running something hot like that can't be good...better to be safe than sorry
