Pipeline HD DVR Drive
The Seagate Pipeline HD ST3320311CS is a 320GB 3.5-inch internal hard drive built for continuous video recording. It spins at 5900 RPM with an 8MB cache and connects over a SATA 3.0Gb/s interface. The drive is supplied new as a bare unit without cables or mounting hardware.
Suited for DVR expansion not OS boot
This drive targets installers and owners of consumer DVR systems that need 24×7 operation and support for up to 16 simultaneous HD streams. It is not a good choice for a primary operating-system disk or for workloads that demand faster random-access performance.
320GB capacity and 5900 RPM spindle
The 320GB capacity and 5900 RPM spindle speed are the key figures that determine whether this drive fits the recording window and throughput your DVR requires. Verify those two numbers against your device specifications before purchase.

Questions about this item
How do I install the 3.5" SATA drive and what step is often missed?
Mount the drive in a 3.5" bay, connect the SATA data and power cables, then enable the port in BIOS so the 320GB volume appears.
What maintenance or replacement will the ST3320311CS need later?
No routine maintenance is required; replace the drive if SMART attributes report reallocated sectors or if the 5900 RPM motor develops bearing noise.
What limit appears first during sustained 24×7 DVR recording?
The 3.0Gb/s SATA interface and 8MB cache can deliver up to 16 simultaneous HD streams before throughput becomes the bottleneck.
