On the Z97 chipset (excluding the asrock) its a x2 speed M.2 socket - I am upgrading to the X99 chipset where all the M.2's are x4.

I cant seem to find any x4 M.2 SSD's, only one is the Samsung XP941 and you cant get that here I believe.
 
Not sure when they will be here, but I just read on the asus deluxe manual "For a higher performance do not install Hyper M.2 x4 if you are using 28 Lane CPU" so that is the 5820K.

Just in case some aren't aware of that, not sure the actual affects tbh.

Thanks that is very interesting, certainly something to reconsider perhaps better to get the next model up CPU and that way no limits at all.

Was just reading up on these and found this: http://www.pugetsystems.com/labs/ar...e-M-2-Qualification-575/#M_2DriveTemperatures

Seems they get very hot!

Anyone actually running one?

Sequential Read: Up to 1170MB/s, Sequential Write: Up to 930 MB/s

My goodness !

thanks for link its great to read much faster SSDs will arrive in the no so distant future hopefully the new controllers are much better and cooler am sure they will get faster and cooler over time, SSDs with heatsinks can't wait!
 
just for the record I have been running my XP941 now for 3 months straight without any issues.
yes its hot but as the heat its "topside" it dissipates quickly and isn't causing a problem. I would like a heatsink etc but until i have issues i'm not gonna worry to much. my HP laptop has a M.2 slot though and sod putting that in there!!! FIRE!!!!

Have you considered moving to an X99 system with m2 x4 to get those insane speeds yet? :D
 
the article linked above said:
While not available right now (that we can find at least) we completely expect someone to come out with a card that adapts four M.2 drives to a single PCI-E x16 slot. This would give you a ton of versatility since you could install four individual M.2 drives into a single motherboard slot or you could RAID the four drives together in a RAID0. Theoretically, this could allow for transfer speeds of up to 8GB/s which would almost match the performance of DDR3-1066 system RAM!

Oh how I would love to do this. I wonder if you'd even notice the difference in everyday use though

it already runs at mental speeds on Z97! I cant imagine it will go any faster on X99. mmmmmm X99.........:D:cool:

Yeah your right not much difference in speeds after double checking that review but pcix4 is slightly faster.

tbh am not really sure how all this bandwith stuff works out anyhow since it was suggested on the Asus X99 manual with 5820k owners to not run a x4 M2 device, perhaps they are suggesting the pci land bandwith will run out or your X4 device will slow down not sure !

Certainly making me reconsider X99 or 5820k platform though, not to mention in that review x2 and x4 difference was little anyhow.

By the time these become mature in a year or 2 perhaps they will have 4 of them strapped onto a pci express 16x card as mentioned!
 
Regarding the 28 lane CPUs, how the motherboard manufacturers do "the plumbing" is left to them. You'll need to check the manual to understand how the more limited number of lanes will be allocated

The MSI X99S SLI pretty much uses 24 lanes for the 16x PCIe Slots (So 16+8, 8+8+8. I can't recall the allocation for Quad SLI, it's way beyond what I'd want to do anyway). The remaining 4 lanes are always allocated to the M2

For 40 lane with triple SLI there is an option for 16+16+8, with the M2 diverted to a 2x PCI-E 2.0 off the chipset. All configurable via BIOS.

4x PCI-E 3.0 is an insane amount of bandwidth, but of course with X99 you're more likely to have 8x or 16x slots available too :)
Worth quickly highlighting that these slots will be PCI-E 3.0, where as X97 is 2.0 - as are all the cards available at present. 3.0 has double the bandwidth

its likely to be a weird combo of lanes like on Z97 where using the M.2 at 4x disables a few SATA ports and the lower socket for example. if I am to use my 2 290x's plus the M.2 plus other PCH hardware its still going to run out of lanes at some point.
 
So its like bandwith theft :)

Not sure I fully understand it all but it sounds like any Z97/X99 user with say 1 single GPU and 1-2 hdds and an m2x4 should still be fine, I have asked the same q on the long haswell thread on the cpu forums also.
 
on my Z97 Deluxe the use of the M.2 drops out 4 SATA ports and the last PCIe slot.

the manual does explain this sort of. it says they "share"!!! they bloody don't though, its one or the other.
 
going to avoid M2 until they sort out the heat issues - its not on to sell devices that get that hot without integrated cooling

Do like the sound of the bandwidth though (although can see you could start limiting your gpu usage pretty fast with multiple M2's)
