GoHardDrive
3TB 3.5-inch SATA desktop drive with 5400 RPM and 64MB cache, built for 24/7 surveillance and NAS workloads
The GoHardDrive 3TB 5400RPM SATA hard drive is built for 24/7 video-surveillance workloads. Its 64MB cache and low-power spindle suit continuous write streams in DVR and NAS appliances. The bare-drive package fits standard 3.5" bays in desktop chassis or external enclosures.
Replacing a smaller drive with this 3TB model extends recording retention without adding bays. The jump is worth it when current storage fills before the desired overwrite window. SATA 6.0Gb/s interface runs at full speed on modern controllers and falls back to 3.0Gb/s on older ports.
Verify the chassis has a free 3.5" slot and a SATA data cable plus a compatible power connector. Confirm the host system or DVR recognises drives larger than 2TB. No mounting screws or rails are included with the bare drive.

Yes, the 3.5-inch form factor matches standard desktop drive bays and mounts with four screws on the bottom or sides.
No jumpers are required; the drive auto-negotiates speed and is backward compatible with SATA 3.0Gb/s systems.
No user maintenance is needed for the cache or shock protection; monitor SMART health attributes periodically and replace the drive if reallocated sectors or seek errors appear.
