NVME RAID-0

[AlaskanRippler]

So basically i want to eventually put two NVME drives in raid-0 to boot but I'm wondering if i can get both drives on one m.2-pcie adapter so i see products like this ( https://www.newegg.com/Product/Product.aspx?Item=9SIA7258012134&cm_re=nvme_pcie_adapter-_-9SIA7258012134-_-Product )but then it says it only supports pciex4 output and that would gimp my drives if true. are there any adapters out there where i could get pcie 8x out of em? am i reading this wrong? SOL?

 

Thanks in advance

what otherboard do you have? you need motherboard support for nvme raid boot.

 

why nvme raid? what are you doing? for most programs optane will be faster than any nand ssd

 

that card supports 1 sata m.2 and 1 mvme/pcie m.2 so it wont work for nvme raid unless you already have a m.2 slot on the board and a supported motherboard.

Mmm....bad idea. RAID0 generally isn't recommended. Do you actually have a need for that speed?

of course not but i want it

 

I should mention that i dont keep sensitive or important data on the pc thats all backed up so if i lose a drive i'm only out the money. purely a hotrod nothing else.

z170-A already booting to nvme on m.2 but i'd like two full speed nvme drives running on four pcie lanes each and i can DO that with the adaptors i have but id like to put em both on a single card so I'm not eating up my x16's (my bad on the card I listed though didn't read carefully enough)

You won't even notice it though. I don't see the point at all. It just adds unnecessary complexity.

like i said, its like guys who build hot-rods its great BECAUSE its stupid

With z170 you have to use the dmi for nvme devices, so your limited to the speeds of the dmi or a pcie 3 x4 link. You won't get any faster sequentical speeds.

 

If you really want the fastest drive, get a optane, those sequentical numbers don't really matter, iops do, and optane has upto 10x more performance than nand ssds.

 

Basically you need x299 or x399 to do this, all the 1151 don't have the lanes setup for this.

And RAID increases the storage latency for most things so it'll be slower not faster, bar copying really big files but I have no idea where one would be copying them in a system like this that could utilize the speed, certainly not across a network.
