Thoughts on these SATA/M.2-->SATA/2.5" adapters?
(feddit.nl)
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?
I'm not saying this rudely. This sounds like a "read the manual" moment, since different vendors can have different settings.
Or at least links to the exact one you are looking at.
I couldn't find any manuals. Nothing that referenced my questions. Thought maybe there was just a "conventional" way that these functioned.
https://www.qnap.com/en/product/qda-a2mar seems to be the one in your image. From the users guide it seems it does everything you listed. The prices I've seen are about 100 € / $ though plus the two SSDs you need, personally I'd invest in external backup instead, that covers more data loss scenarios than this adapter.
That's cool that it has a utility but how would I even access that on a server? And how would I be notified if there was a problem?
External backup is not a possibility.
