14 TB SATA enterprise hard drive

The Western Digital Ultrastar 0F31284 is a 14 TB 3.5-inch internal hard drive built for enterprise storage systems. It spins at 7200 RPM with a 512 MB cache and connects via a SATA 6.0 Gb/s interface. The drive uses conventional magnetic recording and HelioSeal technology to deliver high capacity in a standard form factor.

Suited for high-capacity servers and storage arrays

This drive targets environments that demand sustained 24×7×365 operation and a workload rating up to 550 TB per year. Buyers who need a different interface or a smaller physical size should look elsewhere.

550 TB annual workload rating

The 550 TB per year workload rating is the key figure that separates this Ultrastar model from standard desktop drives. It signals the write endurance expected in enterprise deployments.

Preguntas sobre este artículo

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.
