do i have enough lanes to do raid0 for (2) gen4 drives on Z690 chipset?

[lemmywane]

sorry, I'm new to this stuff. even newer to anything raid. 

 

What I want to do is run (2) 2tb nvme gen4 drives in a raid0. My mobo has three gen4 nvme slots. I'd be running a third gen4 nvme in that first slot for the OS. and also have a lower tier gpu in the 5.0x16 slot. 

 

my biggest question is whether the z690/12500 can handle it? would there be enough lanes to use all of this without a performance drop? nothing graphic intensive going on with this build so if it affected the GPU that wouldn't be a problem, even. Just want to make sure I wouldn't see any performance drops with the raid0 volume compared to if I just used a single 4tb drive. 

 

sorry if that's confusing at all.  thanks for any help!

Why?

[lemmywane]

for my use case it would be a lot more convenient for it to be a 4tb volume than two separate 2tb volumes

Raid 0 is stupid, just because its there doesn't mean you should do it.

really? I don't know much about it. what are the big drawbacks?

You get a speed advantage, but if either of the drives fails you'll lose all the data on both drives. RAID 0 should only be used for temporary, high speed storage of files that you can afford to lose or you have a constant backup of.

thanks! that describes my use-case exactly so it sounds like it could benefit me

Anyway, with that cleared up, the answer is likely "yes", unless your motherboard is unusual. So what motherboard is it?

Do you actually need the speed advantage offered by multiple drives in RAID 0? Modern NVMe drives are already very fast on their own, and you'll want another storage device to hold a second copy of the data long-term.

Yup, you are good to go.

honestly I'm not even trying to achieve a speed/performance increase. for now because it is so much cheaper to grab two 2tb drives than a single 4tb gen4 drive, I'm doing it to achieve that 4tb volume size. my only real concern is the performance dropping at all. If I can get the same performance with raid0 as I would with the single drive I'd be pretty happy. just wondering if I have enough pcie lanes to achieve that. thanks for your help btw

You can do JBOD "raid" to merge the two drives. But if all you want is 4TB on a single drive letter, you can mount one drive as a folder on the other drive in Windows. That way the data is still intact if one dies or you need to recover data, for reason x, with another computer in the future. Using bios software raid for nvme drives is not really worth the downsides.
