Specifically, it's more about RAIDing with different interfaces.

  1. If i have an m.2 SATA 2280 SSD with an identical (size and manufacturer, so more likely to really be the same capacity). Can i RAID that with an m.2 SATA 22110 SSD.

  2. Also, could i RAID the same m.2 SATA 2280 SSD with an m.2 NVMe 2280 (or 22110 again).

  3. One plugged in the onboard slot and the other on the PCIe slot.

I think that's all the possible variations.

I have 2 onboard slots, a SSD SATA slot, and a SSD NVMe slot.

I also have two PCIe cards; one for a SATA SSD, and one for a MVMe SSD, and I'm looking into a PCIe slot that has both a SATA and an MVNe slots.

I would prefer to use the PCIe cards as they work faster, but I'm but married to it, anything is going to be much faster than a 5400rpm HDD.

The mother-board allows both m.2 drives be plugged in at once. In general it supports many raid options for the SATA HDDs, but doesn't say anything about RAIDing with SSD drives. Should that matter, should it be assumed it does support it as it supports the RAID options at all?

If it's more about whether the motherboard can handle it, is the only way to find out by plugging then in and seeing? (Support for my MB is lacking so i kinda can really go by the manual and spec sheet.

If it's all down to what the motherboard allows and doesn't allow then i won't spend as much on the second drive to test it, so i suppose I'm asking if anyone has experience doing this, or the knowledge to just know the answer.

This is mostly to avoid buying a second SSD that's identical, or slightly different (2280 vs 22110; SATA vs MVMe; etc).

I think my question is too confusing, but you guys are normally quite awesome answering my questions and understand the essence of my questions, so I'm hoping for that scenario here.

  • The specs for the two drives in a RAID 0 array should be as close a possible, ideally they should be identical. I'm assuming you want to combine two drives and gain speed advantage. nvme drives are way faster than SDD and should not be put into a RAID 0 array. – Bernard Wei Jul 29 '18 at 5:52
