That was a rather harsh, sweeping statement. The Two SATA Express ports could also be used as four SATA III ports. Just because you don't need that many SATA ports doesn't mean no one else does.

OK thanks for the information - And your opinion of the SATA Express ports, but they could still be used as regular SATA 3 ports I suppose.

OK, another question, off topic for this thread but along similar lines of SSD's just so another new thread is avoided.

I've got an Asus Z97-AR which has 2 x PCI-e x16 GEN 3 slots - One of these slots could be used to house the adapter card for an NVME PCI-e GEN 3 @ x4 speed lanes to the CPU.

I've seen an adapter card that will house 4 x of these NVME M.2 drives - What is possible here? - One could just be installed and leave it at that or....... please elaborate on the options.

I've been reading up on the companies such as Western Digital, Samsung, Kingston, Crucial but it is difficult to know of every best option

Using an NVME in PCI-e x16 GEN 3 slot could help to get the best out of this system and use in conjunction with the chipset lanes

Any useful input welcome always - smile.gif thanks

Z97 lanes are very limited, sure you can run some nice storage via cards but lose x16 GPU for sure.

Yes if this was for a gaming system one of the slots would be used for GPU @ x16, however, if this is not a gaming system then I'd use integrated graphics for home studio hobby so the 16 CPU lanes would be spare, X4 twice, one for storage card, the other for an audio card @ x4 so it could work out well.

I've found a Star Tech 3 x M.2 adapter card, 1 x PCI-e GEN 3 @ x4 and 2 x 6 Gb/s M.2's all through the CPU - Voila!!!

Do you know of any other companies that do similar? - It's just having a look to see what can be found! - But one of those cards with 3 x drives is awesome - Not RAID compatible but I've not done RAID yet!!! - But a good way to max out the Z97 board I've got so it remains useful into the future.

When will the M.2's drop in price? both the PCI-e and the 6 Gb/s interface? - At some point they will surely

OK again this isn't for SATA Express drive because none were made - smile.gif

I'd like an opinion on this please

https://www.startech.com/uk/Cards-Adapters/HDD-Controllers/SATA-Cards/pcie-m2-ngff-ssd-adapter-card~PEXM2SAT32N1

Above is a link for a StarTech 3 port M.2 PCI-e card to support 2 x M.2 SSD with SATA 3 6 Gb/s interface and 1 x M.2 PCI-e GEN 3 x4 interface

Apparently full bandwidth is available simultaneously up to 40 Gb/s for the PCI-e M.2 & 6 Gb/s for M.2 SATA III interface - All that bandwidth together is up to 52 Gb/s isn't it? - And PCI-e GEN 3 x4 = 40 Gb/s max - Is this correct?

Is there any way if all 3 ports were populated that the 6 Gb/s + 6 Gb/s = 12 Gb/s would be subtracted from 40 Gb/s - 12 Gb/s = 28 Gb/s for the M.2 PCI-e?

I sure would like full speed on all 3 but is this really possible?

It would be tested at some point to verify but in theory how would this pan out in real world use? - Thanks:)

Well I do believe I've found the answer, as if an M.2 PCI-e adapter is used with 6 GB/s interface it is necessary to connect SATA data cables from the SATA III ports into the SATA data connection on the M.2 PCI-e adapter card.

This then would preserve the bandwidth of the M.2 PCI-e GEN 3 x4 M.2 drive - So that is that folks -
