Purpose-built surveillance storage

The Seagate SV35.6 ST1000VX000 is a 1TB 3.5-inch internal hard drive engineered for continuous video recording. It targets installers and system integrators who need cost-effective capacity for 24x7 security arrays. Buyers wanting a general-purpose desktop drive or an SSD for boot applications should look elsewhere.

SATA 6.0Gb/s interface and 7200 RPM spindle

The drive connects through a standard SATA 6.0Gb/s port and spins at 7200 RPM with 64MB cache. Average seek time is <8.5ms and average write time is <9.5ms. These figures determine whether the drive can sustain the write throughput your recorder demands.

Straightforward 3.5-inch bay installation

Mount the unit in any 3.5-inch bay using the 19.99mm height, 101.60mm width and 146.99mm length envelope. Connect SATA data and power cables; no special drivers are required. Note that units may show up to 25 bad sectors and have been erased to DoD 5220.22 M standard, so they arrive unformatted and unpartitioned.

Questions about this item

How does the 7200 RPM spindle speed translate to real-world performance in a surveillance system?

The 7200 RPM rotation combined with a 64MB cache delivers sustained throughput for multiple simultaneous high-definition video streams, while the <8.5ms average seek time and <9.5ms average write time keep frame drops to a minimum during continuous 24x7 recording.

What does the SATA 6.0Gb/s interface actually limit in practice?

The SATA 6.0Gb/s link caps the maximum burst transfer rate at 6.0Gb/s, but sustained read and write speeds are governed by the 7200 RPM platters and 64MB cache, so real-world throughput stays well below the interface ceiling.

Will this 3.5-inch drive fit my standard desktop drive bay or surveillance enclosure?

Yes — the drive measures 146.99mm long, 101.60mm wide and 19.99mm high, matching the standard 3.5-inch form factor used in desktop bays, DVRs and NVRs.
