DVR-optimised 300 GB desktop drive

The Seagate DB35 ST3300831SCE is a 3.5-inch desktop hard drive built for digital video recorders. It spins at 7200 RPM with an 8 MB cache and a SATA 1.5Gb/s interface. The firmware supports multiple stream recording for up to 10 television streams at once. Operating acoustics are rated as low as 2.7 bels for near-silent operation. Average latency is 4.16 ms.

Check SATA 1.5Gb/s host support

Verify that your system provides a SATA 1.5Gb/s port and can supply power to a standard 3.5-inch drive. The bare drive ships without cables, brackets or mounting screws, so confirm you have the necessary SATA data and power leads. The low-profile 1.0-inch height fits most desktop bays, but ensure the chassis has clearance for a full-height 3.5-inch unit. This is a refurbished drive, so plan for a clean OS install or DVR firmware load.

Replaces older DVR drives below 300 GB

The 300 GB capacity upgrades smaller drives that can no longer hold the required recording window. The jump is worth it when you need the 150 MB/s interface throughput and the proven reliability for extended field life in a DVR. It is not suited for users who need more storage than 300 GB or for systems that require a SATA 3Gb/s or faster interface. Builders needing a second drive for RAID or general-purpose desktop storage should look elsewhere.

Questions about this item

Does the bare drive include cables or mounting hardware, or do I need to buy a SATA data cable and screws separately?

The drive is supplied as a bare unit only; a SATA data cable and 3.5" mounting screws are not included and must be purchased separately.

Should I choose the 300 GB DB35 model or a different capacity for recording up to 10 TV streams at once?

This specific model provides 300 GB capacity and is rated for up to 10 simultaneous television streams; other capacities are not covered by these specifications.

What real-world throughput can I expect from the SATA 1.5 Gb/s interface on this 7200 RPM drive?

The SATA 1.5 Gb/s interface delivers up to 150 MB/s burst throughput; sustained transfer will be lower and depends on system workload.
