this. I have like 16 ports or something on that board but only 10-12 can actually work.Not enough SATA ports or PCI-E lanes. Look very carefully into what gets disabled on a motherboard when using a PCI-E M.2 SSD.
You can get PCIe adapters for M.2 SSDs pretty cheap. Not that there are a lot of interesting M.2 drives right now except for the SM951..
Indeed. Gigabyte alone has announced 5 motherboards with dual M.2.Wait for Skylake
Skylake only has DMI 3.0...one would have hoped like me that they would have at least doubled it right? Nope, its only 8 GT/s. So your stuck at like 3 GBps
It's easy to confuse the 5GT/s and 8GT/s specs. The 8GT/s is actually twice the data throughput as the 5GT/s due to the change from 8b/10b encoding (20% overhead) to 128b/130b encoding (1.5% overhead).
* M2_1, SATA3_0, SATA3_1 and SATA_EXP0 share lanes. If either one of them is in use, the others will be disabled.
* M2_2, SATA3_2, SATA3_3 and SATA_EXP1 share lanes. If either one of them is in us
e, the others will be disabled.
* M2_3, SATA3_4, SATA3_5 and SATA_EXP2 share lanes. If either one of them is in use
, the others will be disabled.
From the manual:
Impressive that they don't share with any of the PCI-E slots, but there's a reason for that - the really fancy thing to do with that motherboard is seven Intel 750 PCI-E SSDs in RAID 0
That 35 MB/s 4K though...
better to use X99 because you have virtually no lanes to use on Z170. You would be better served that way.
A thousand times THIS. Everyone is hanging multiple M.2 slots off of the Z170 DMI. Even the expensive $400+ boards with PEX PCIe bridges will use them for "quad-SLI" and not bother branching 4 lanes off to an M.2. WTF?

ASRock uses nine Texas Instruments HD3SS3415 which are PCI-E 3.0 quick switches; each can switch two lanes of PCI-E 3.0. Six are used to switch PCI-E lanes from the CPU to three PCI-E 16x slots. The remaining three are used to switch 2x PCI-E 3.0/ 2x SATA between each SATA Express port and each M.2 connector.
The only way you're getting 28 dedicated PCIe lanes for storage on a consumer platform is X99-5930/5960....
LOL! Those CDM stats match with THREE Intel 750s in RAID 0. Just as well, because the CPU's 16 direct PCI-E are split 8/4/4 to the first three x16 slots, while the fourth x16 slot (at x4) and ALL of the M.2s/SATA/SATAExpress hang off of the DMI.
From the Tweaktown circuit analysis:
So does it make sense to buy an M.2 Mobo these days? For a simple home htpc/ hack box?
I agree. I will go for bottom feeder as a Temp, only if I know for sure that the NextGen is coming out in near future and thats where I want to build house.i honestly dont understand why people buy shit motherboards.....I mean if your making super cheap budget PC with a celeron sure but if your building a decent computer or a good one i can't fathom why people by crap MB. Quality ones are worth every penny in my book.
Msata?
The second M.2 I believe is actually PCIe Gen 2 x2 and not just sata. So it actually supports decent speeds. It sucks up the 2x PCIe off the PCH so it can use 1GBps IIRC Gen 2 correctly.
there are notable times of upgrading..particularly die shrinks or major changes. I.E.Next gen is always around the corner. Wait if you can, just buy now if you cannot or don't want to wait. There's no point in delaying a purchase because the next thing is right around the corner. There's very little point in buying placeholders either.
