If it’s split up sure, but I’m talking about a raid > 0 setup and/or having backup copies of your data onto drive #2
Raid0? You mean having two devices stripped across is rather than just one device with no stripping? Raid0 is a risk you take when you care more about performance than downtime to restore a backup.
If I have 20TB of data, it cannot fit on a single 16TB drive. So my options are Raid, or this single drive option. I would always pick the single drive if I could afford it.
Double check that symbol there.
Raid 5 is a great balance of capacity and useful storage with 3 drives. You get 1 drive worth of fault tolerance and 2 drives worth of capacity. I personally have mismatched drives so I run raid 1 in between the matching sizes, and jbod between the raid 1 mirrors (well the zfs equivilent) And my really important data is backed up onto two more drives in raid 10.
The person I replied to said
I’m uncomfortable storing 16TB worth of data on one drive
as a criticism of using a single 32TB drive.
I argue that a single 32TB drive is less risk than using 2 16TB drives. Am I wrong?
