It earns the extra once you're filling a big box or hammering the array with Plex and backups around the clock, as the 550 TB a year rating leaves plenty of headroom. Five years of warranty is the other draw, and on a drive you'll leave spinning for most of a decade that's worth having. Recording is CMR, the right kind for RAID and ZFS.

There's no Backblaze data worth quoting here. Power draw is 4.25 W idle and 7.83 W working on Synology's figures, or 37 kWh a year if it spends the whole year idling. A 4-bay box full of these gives 36 TB after one drive's worth of parity.
