With SSD storage, what what your thoughts on redundant storage devices (e.g RAID1), is it a waste, a nice to have or a must?
what are your experiences and thoughts on this ?
Appreciate your opinion, as I will probably move from HDD to SSD.
SSD’s are cheap nowadays. They’re also much more reliable than HDD’s. That said, when they fail it’s usually catastrophic failure with total data loss.
If your data that’s important to you, I would still use redundant storage. Especially since the cost is minimal.
It depends how valuable your data is, what backup strategy you have, and how long you’re prepared to wait to get access to your data when a drive fails.
Personally if/when I migrate my main dataset to SSD, I’ll stick with RAIDZ2/RAID6.
I’ve had SSDs go bad. So if it’s something you really care about I’d approach it the same as hard disks.
Depends on how attached you are on your data, if you have a backup, if you can do without the data created between backup cycles and how long you can wait for the restore to finish.
Everything will fail. For me, everything on single disk is expendable or backupped and can be done without when I loose a day/week of data. Everything else is on raid 1 (hdd) and in a backup schedule (external hdd).
As someone else has pointed out, it really depends on your use case. Although I personally keep my drives (SSD & HDD) in a redundant RAID configuration as my data is largely mission-critical.
I think it depends on the usage actually. Will there be lots of read and writes? SSDs are quite reliable nowadays.
Raid5 (well raidz1) has saved my ass multiple times. Just dont forget to also raid your efi and swap partitions
(just to add, and clarify - no more than 2 disks)
