    Add new SSD drive to RAID-1 machine?


    My PC runs Windows 10 Home 20H2 off a RAID-1 HD (configuration: BIOS-> SATA->RAID). I would like to add a new, separate SSD drive to this system. Can this be done without interfering with the existing RAID-1?

    That would depend upon whether your motherboard allows specific SATA ports to be excluded from the RAID array.

    Only limited experience with RAID and only by chance but I'd have to agree. From reading about drive problems it seems some of the newer boards have issues with connecting a mix of drives when the NVME and/or m.2 drive capability is present with SATA ports and sharing of them.

    I have a Z68 MB with a i7 2600k
    For many years I had a single and small SSD and two HDD on a Raid 0 array.

    In BIOS the SATA ports must be as they are now (RAID, not AHCI)
    Just insert the new SSD into a SATA port make sure it is recognized in BIOS and initialize and format it under windows.

    The experience I mentioned was a Dell computer with a BIOS that had 2 choices, one setting choice was Legacy and the other setting choice was AHCI/RAID. With 2 drives in the case Windows automatically used the RAID part and I didn't realize it until I removed the second/D: drive and it wouldn't boot, had to start over.

    My guess is that with Raid 1 (mirroring) there would be no issue, as Raid 1 uses just a pair of drives.

    I haven't used motherboard RAID in years. I once had a 4 drive Raid 10 array. I got tired of it re-verifying the array every time Windows crashed. The PC was still usable, but with HD performance that was degraded for hours.

    Thank you all. The reason for choosing the RAID-1 configuration was reliability. It is extremely stable, if fact, it's my only rig with no HD failure in over 11 years. I think I'll skip the SSD for now.

    The great advantage of a SSD is speed. It is almost 6 times faster than a HDD. Boots in 25 sec and open programs at a blink of an eye.
    You can install a small SSD (128G - US$25) for windows an programs and use the HDDs for data only. It's a way to have the speed of a SSD and the space of a HDD at low cost.
    That is may configuration on the desktop and laptop.

    Raid configurations alongside standalone disks is achievable in most cases whether the hardware is modern or not. On motherboard raid must be configured as such using a software raid utility in most cases.
