2TB surveillance hard drives
This range covers 2TB 3.5in SATA hard drives for DVR/NVR recording, built for continuous write cycles rather than desktop use. Four lines are stocked: Toshiba S300 (5400RPM), Lenovo 00XH226/02YH047/03GX258 (7.2K RPM, SATA 6Gb/s), a generic 2TB 3.5in SATA drive, and a Seagate 2TB 3.5in SATA drive.
How to choose
- Spindle speed: the Toshiba S300 runs at 5400RPM, suited to steady 24/7 streaming workloads with lower heat and noise. The Lenovo drives run at 7.2K RPM for higher throughput, useful where multiple high-bitrate channels write simultaneously.
- Interface: all four are SATA; the Lenovo drives are explicitly rated SATA 6Gb/s, worth checking against your recorder's SATA generation for full bandwidth.
- Part-number matching: the Lenovo drive is listed under three interchangeable part numbers (00XH226, 02YH047, 03GX258) — any of these fulfils the same slot in compatible chassis.
- Form factor: every drive here is 3.5in, the standard bay size for DVR/NVR internal storage.
- Use case: the generic and Seagate 2TB drives are both positioned for 24/7 continuous recording, matching typical CCTV duty cycles rather than intermittent desktop I/O.
Confirm your recorder's supported drive list and maximum single-disk capacity before ordering.
2TB — frequently asked questions
What size hard drive bay do these 2TB drives need?
All four drives are 3.5in form factor, the standard internal bay size used in most DVR and NVR recorders.
What's the difference between the Toshiba S300 and the Lenovo drives?
The Toshiba S300 spins at 5400RPM, while the Lenovo 00XH226/02YH047/03GX258 drives run at 7.2K RPM over SATA 6Gb/s, giving higher throughput for busier recording setups.
Are the three Lenovo part numbers different products?
No — 00XH226, 02YH047 and 03GX258 refer to the same 2TB 7.2K SATA 6Gb/s drive under different part numbers, so any one fulfils the same role.
