Capacity and workload fit

The Western Digital Purple Pro delivers 14 TB of storage on a 3.5-inch SATA drive built for continuous video-surveillance and server workloads. It spins at 7200 rpm and uses conventional magnetic recording with a 512 MB cache to sustain high write throughput. The drive is rated for 550 TB of total bytes written per year.

Annual endurance rating

The 550 TB per year workload rating is the single figure that tells you whether this drive matches your recording retention and camera count. Buyers who need a lower endurance drive for lighter surveillance or desktop use should look elsewhere.

Questions about this item

What does the 14 TB capacity mean once the drive is installed in a real machine?

You gain roughly 14 terabytes of raw storage for surveillance footage, server archives or bulk data, formatted to slightly less by the file system.

What does the SATA 600 interface cap in practice?

The SATA 600 link tops out at 6 Gb/s, so sustained reads and writes cannot exceed that bandwidth regardless of the 7200 rpm platters.
