Questions about this item

Does the bare drive come with cables or mounting hardware, or do I need to buy them separately?

The drive is supplied as a bare unit only. SATA data and power cables plus any 3.5-inch mounting screws or trays must be purchased separately.

The specs mention Ultrastar DC HC530 — is that a different capacity or the same 14 TB model?

DC HC530 is the series name for this 14 TB, 7200 RPM, 512 MB cache SATA drive; there is no separate capacity choice under that series in this listing.

What does the 550 TB per year workload rating mean for daily use in a server?

It means the drive is built to handle up to 550 TB of data written or read each year — roughly 1.5 TB per day — far above typical desktop drives.
