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).
If I use RAID 1 and one of the drives fails, will I know?
If a drive fails, and a slap in a new one, will it internally begin repairing RAID 1 again?
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?
If I'm not wrong these are not compatible with nvme? I remember I wanted to buy something like this but I couldn't find PCIE to SATA, pretty sure I'm wrong but not in the mood to research
IIR there are 2 versions, one using SATA protocol and the other using PCIe. The difference is keyed into cutouts between pins.
I'm not entirely sure what the benefit of this setup would be over 2 independent SSD's since one drive will max out the connection speed and 2 can use 2 ports.
I've had a 2x SATA-based m.2 RAID card that plugged into PCIe for a boost in speed ages ago. It was fun, but I swapped it out for true PCIe based m.2.
I think their goal is to minimize space since it's a mini-pc, so they don't have 2 slots to spare but still want 2 drives? That's how I interpreted it, at least.
Heat may be an issue if it is very cramped, but could work. Letting the motherboard handle raid would be better, but add one heck of a bottleneck. I'm still leaning towards one large SSD or perhaps external storage.
A video archive on external would work fine for a couple users, but sharing disk bandwidth with the system would suck pretty fast.
Have you considered SD card(s) as your redundancy? They're not great/ideal, but microSD are incredibly small. Or this may be a good use case for a local NAS placed somewhere else in your home that your PC backs up to nightly?
