How to choose 12 TB hard drives

What to look for

Price per TB: compare with 8 TB and 16 TB. The cheapest size per TB moves with the market and with how many renewed drives are listed.
Helium and noise: many high-capacity drives are sealed with helium, and some can be loud under load.
Backup: a 12 TB drive holds a lot to lose, so keep a second copy of important data.
Condition and warranty: renewed drives are common at this size, so read the seller's warranty.
Rebuild time: in a RAID array a big drive takes a long time to rebuild, so consider the array design.

Best for

Large media libraries, NAS builds and archive storage.

Skip it if

You need only a few TB, since smaller drives cost less in total and are easier to replace.
