$5 a TB is insanely cheap and someone just getting rid of stuff and not really caring about the price. Nothing has ever been that cheap at retail or manufacturer recertified. Lowest was like $9-10 last year and now we are sitting at more like $15.

Yeah it was interesting because the guy knew what he was doing unlike other great deals I've had. I guess he just really didn't want them

... might wanna zero those drives just in case

They came uninitialized, but yeah it could be worthwhile to actually zero and fully format them. They are decently fast at 275 MB/s but even that's 16 hours to do one pass. Maybe let it run over the weekend

16 hours isn't that bad. I recently had to zero my old 2tb Time Capsule and just let it run overnight and during work, wasn't so bad. You'd also get to detect bad sectors, figure out how good the drive is in terms of what % of the drive is actually usable for large sequential writes
