Got a deal there then
I'm up to 46.25tb now, I'm most likely going to clone the c drive onto a 4tb one at some point bringing me to 50TB but space is something I always hated running out of have plenty atm but it'll go in time, but 10 drives at that price is well worth it as I feel ex server drives still tend to last well it's not like drives don't fail but when they do it's a pain so always something you want more than you need to use for when that happens.
As for Toyota that is neglect and oversight loss of production like that must be costing them a fortune.
