Question Advice for RAID 0 on Asus ROG x670e motherboard

[GregP74]

Hey all! I've never set up a RAID array before so I'm looking for suggestions/tips on my next project.

I've got a pair of 2tb m.2 drives coming tomorrow. My plan is to do a RAID 0 array with the 2 of them for Windows and applications. I plan on just using my old 4tb m.2 for data files on its own.

Any tips on what to do? How to set it up? I would assume that the pair of 2tb drives should be in the m.2_1 and m.2_2 slots.

RAID 0 is pointless with SSD's, IMHO, you won't realize the speed in real world applications, which would mean you're going through multiple hoops for no reason.

What are full system specs? Are the M.2 drives exact brand model (specs)? Are they NVMe?

Why do you want to do a RAID 0 with M.2 drives?

Any advantage you, the user, MIGHT see would be minimal. Maybe blazing scores in sythetic benchmarks.

Two M.2s RAIDed might even saturate the bandwidth limit at times under heavy work load and the overhead can actually bottleneck transfer speeds at times.

Also RAID 0 is stripping, no redundancy. One drive is gone all data is gone. So a solid backup plan is even more imporant than when you have 2 independent drives.

Tips? Don't do it.

Yeah they are identical WD Black 2TB 7300MB/s SN850X NVME drives. I was going to use one in another PC then thought "heeeeey I could put those both in here and get the disk speed faster!" Perhaps I've been listening too much to the weenie at work who's always bragging about how fast his disks are when running that setup.

(System is a 7800X3D on an Asus ROG Strix X670E-E motherboard with 64mb ddr5 and GEForce 4080 video card.)

My suggestion is - Don't.

RAID 0 + SSD often results in slower performance.

These, from several years ago. But I've not seen anything to refute it.

Yes, he is a weenie.

Benchmarks may look great. So what.
Actual user facing performance, not so much.

Thanks! I'll find a better use for that second drive. (Or send it back and put the $ towards something more useful.)
