Trying to squeeze some more storage in my MiniPC. I have questions about these. These use hardward RAID with selectable modes (Individual/JBOD/RAID1/RAID2).

  1. If I use RAID 1 and one of the drives fails, will I know?

  2. If a drive fails, and a slap in a new one, will it internally begin repairing RAID 1 again?

  3. Can I use these as “individual” or JBOD and have 2 separate drives through the same connector, and use something like TrueNAS to software-RAID them?

    The equivalent of SAS expanders for SATA are called port multipliers, and the JMS562 chip in the picture can act as one (as well as becoming a sort of RAID controller).
