Do both m.2 have to be identical for raid0?

[kennethk]

I'm attempting to raid0 two nvmes, one is a solidigm 2tb the other is a kingston 1tb ssd. I got this Kingston on sale for $35 so figure why not attempt to raid it. Since I've never done this before I was following a tutorial and I'm getting an error

 

There are no disks that can be converted to Raid Disk. 

 

However both are displaying in bios. So I'm just not sure if both have to be the same exact model or I'm missing a step. Gigabyte AORUS b550 a v2.

Highly recommend not doing raid 0. There is very little point for NVME SSDs.

 

RAID 0 goes to the smallest size, so in this case i t would be a 2 TB raid 0 array, which is pretty pointless to have a 1 TB and 2 TB drive for 3 TB total if you just used both separately.

So what do you recommend?

use them normally, Id do 1TB as the boot drive, 2 TB as the game drive/general storage drive.

Thanks but that's not my goal obviously

What exactly is the goal? Raid 0 is absolutely pointless with the speeds of NVME drives, you dont get any noticeable gains from doing it. You can get a Gen4 NVME drive if you need speed since you have a b550 board. Raid 0 has pretty much become obsolete as it was intended for HDDs, not SSDS.

 

What is your goal for this?

To extend C drive capacity

Raid 0 will not do that with two drives with different sizes. Just use the bigger drive if you want your C drive to be bigger, although i dont see the reason for it.

Hopefully someone else may have better advice

Please dont use different size drives in raid, it's not recommended 

[Nuzicx]

It's also not recommended to use drives of different specs, ie read write times, latency, rpm. Its best to use same brand and model for this reason

On the BIOS level Gigabyte only supports RAID0 (stripe) or RAID1 (mirror). You would have wanted RAID0 to "combine" both drives into one, but since you have mismatched disk sizes the BIOS won't let you. On a technical level RAID0 on disks of different sizes usually results in striping across the drive of smallest size, so even if Gigabyte allowed you to use RAID0, you'd only have  2TB of useable space.

 

What you want to get the full 3TB is some sort of JBOD configuration, but to my knowledge no BIOS supports this and Windows won't boot from such a configuration anyways.

 

The best you can do is to use symlinks to force certain directories to use the second drive. Or buy a larger drive and sell both of these.

I might've figured oh well worth a try

That's actually coming across as very, very rude. Shimejii actually gave you solid useful advice. If you came here wanting to hear something in particular rather than the truth, i'm not sure what the point of the question was.

The question was... "How can I get what I want,.. while ignoring the advice given,.. and still get what I want?"

 

OP I'd use the 2TB NVME as your C:\, also....Do you know that your files are likely to be done on the read/write (finished reading/writing) before it even hits Raid 0 max speed anyway? And only in sequential files would it likely ever be seen, if at all,... tiny files perform slower than large sequential files, and large sequential files are rare enough of a workload you'll likely never see max speed unless in specific scenarios.

I'm not sure what the point is in continuing the discussion.
