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.
Like others said: it depends.
In my opinion the most important thing to have is an off-site backup. If you have achvieved that, it’s only a matter of how long you are willing to wait for the recovery. If your answer is something like “it cannot wait” then you should go with at least raid 1 and consider additional meausres for the event when your whole array fails.
I’m quite disappointed by most comments so far talking about RAID and data loss. That is not what RAID is for at all.
RAID is for uptime/availability. When a drive fails, the system will keep running and working. For companies, that would lose thousands of currency per hour with a downtime, this is super important that the system keeps running. At home, it’s convenience that you can order a new drive and replace without hours of setting up and copying before you can watch the next episode again.
Backups are against data loss. If a single drive fails, a RAID fails or you get some encryption malware or an employee destroys stuff on purpose, then everything is destroyed. It doesn’t matter if it was a single, any RAID, HDD or SSD. You order a new drive, make a new volume and restore the data from your backup.
