Seagate ST1000VT001 1 TB 2.5" SATA HDD 5400 RPM 128 MB cache

Product identity

The Seagate ST1000VT001 is a 1 TB 2.5 inch SATA hard drive built for continuous video workloads. Its 5400 RPM spindle and 128 MB cache are tuned for low power draw and quiet operation in always-on environments.

Who it suits and who it does not

This drive fits DVR, CCTV and multi-room streaming systems that need up to 16 simultaneous HD streams and 24x7 reliability at temperatures up to 75 °C. It is not for buyers who want faster random access for operating systems or primary gaming storage.

Capacity and headroom

One terabyte holds large video libraries and handles sustained sequential writes for recording without bottleneck. The 5400 RPM speed limits burst performance, so heavy random workloads or rapid file copying will run out of headroom quickly.
