You might want to check out Jeff Geerling’s youtube videos about NAS using raspberry Pi.
Word of caution regarding the name brand route:
I plumped for a 4-bay NetGear ReadyNAS with 2x 2tb drives some years ago, it seemed nice and solid hardware, worked perfectly, all was excellent until I ran out of space and decided to add 2 new HDDs. For maximum possible compatibility I put in two new drives *identical* to the ones it came with. Rebooted, it found them fine, and said ‘rebuilding raid array’ for several hours.
I came back to a warning about an error with one of the new drives – of course possible, but being brand new from a reputable distributor, could be a false positive too, not important though.
The problem was that the error offered no possibility to recover my data. It just declared the whole raid setup a failure wanted to reformat the whole lot! I was naively shocked it could not handle reverting to its previous perfectly OK configuration.
Unfortunately, and the moral of the story, I had used Netgear’s proprietary X-raid system. This means that it is not possible to attempt recovery using open source/third party paid or freemium tools which I could if it were using standard raid protocols. X-Raid meant it would have to be sent away, at high cost, to Netgear (/approved) repairers, with minimal guarantees. Due to customer confidentiality contracts on some of the data within, I am unable to do that, so I had to take the hit of losing everything, pending finding a third way – it’s been a long while now and I’m yet to find it. It’s very frustrating as there is a load personal data (family photos etc) and some CAD work of mine I really want to recover. The customer work related stuff I got past some time ago as everything current was mirrored on my work PC.
So if you do use branded hardware, look very closely at the recovery options and run a mile from vendor lock-in! And, even a raid mirror drive is not actually a backup, in this circumstance.
Ideas for recovering Netgear X-raid, anyone?
Cheers,
Alex Gibson
