Refurbished Western Digital Purple 2TB WD23PURZ 3.5" SATA III HDD 64MB Cache

Refurbished Western Digital Purple 2TB WD23PURZ is a 3.5-inch SATA III hard drive with 2TB capacity and a 64MB cache, designed for continuous-write environments such as CCTV DVR and NVR systems. It is offered as a refurbished unit with a three-month warranty and is intended for use where reliable sequential recording and storage of surveillance footage are required.

Advantages

This 3.5" SATA III HDD provides high-capacity storage optimized for surveillance workloads, supporting continuous recording and multiple camera streams. The 64MB cache helps with sustained write performance, and the drive’s design focuses on reliability for long-duration operation typical of video recording systems. Being refurbished, it offers a lower-cost option for expanding storage while retaining core functional characteristics for surveillance use.

Suitable for

• Digital video recorders (DVR) and network video recorders (NVR)
• Surveillance systems with continuous-write requirements
• Storage expansion for small to medium CCTV installations
• Archival of recorded footage where budget is a priority

When it may not be suitable
