Good work getting site back up.
I still prefer the old magnetic drives. I know they are slower, but they don't have all this cell wear problem. Also extra precautions need to be taken with SSDs if using as an encrypted drive, such as not using the TRIM command.
That's what backups are for. If you don't have backups then you probably don't really care about that data anyway. Platter drives have their place, so do SSDs.
sure!!!
raid conf > 0, and RAID 1+0 too, is not to backup replace!!!
you need always to backup your data.
especially when it is possible to do hot backup like over DB.
