So, I have a NAS with 4 drives in it (4 * 3TB in RAID 10 = 6TB total). 2 of those drives are failing and I get lots of emails every day informing me of that. It also says the bad sector count is 6816 on one of those drives. That's probably a big number.
Anyway, that's just what's going on. This isn't gonna be a "hey should I replace those drives" question because I know people would see that number and glare at me.
The NAS is a DiskStation DS413j, and the failing drives are both Hitachi HDS723030BLE640, in case that matters. I figured I should at least go for a NAS-optimized drive.
I can get the WD Red (one of which I already have and isn't failing) for $135, or the Seagate IronWolf for $128. Though I looked up the benchmarks and apparently the WD Red is a lot better at random reads (which is what I want because I have a lot of games stored on the NAS, and I know sequential reads don't really matter that much and would be bottlenecked by the network anyway).
So, is the $7 worth it for something that's gonna allegedly perform better and is seemingly known to be reliable, or should I just get the IronWolf (which seems to be more in stock)? Should I get a 6TB backup drive first because I was an idiot when I set this all up and never budgeted for that originally and now I realise that was a bad idea?
I'm just indecisive, but it's probably not good if I get stuck in an indecision loop and never swap those two drives out. I overthink things a lot.
