About this product
This is a used WD Purple 4TB surveillance internal hard drive, model WD40PURX, in a 3.5-inch desktop HDD form factor. It operates at 5400 RPM with a 64MB cache and supports SATA I and SATA III interfaces. Designed for continuous recording in PC-compatible surveillance systems, this drive offers substantial storage capacity for video footage. As a used unit, the manufacturer warranty is noted as expired.
Our take
Picking up a used surveillance drive like this WD Purple 4TB WD40PURX can be a cost-effective way to expand storage for a home or small business CCTV system. The 4TB capacity is excellent for storing many days or weeks of continuous footage, even from multiple cameras. The 5400 RPM speed, combined with a 64MB cache, is typical for surveillance drives, balancing efficiency and sustained write performance. Being a 3.5-inch drive, it's suitable for most desktop cases or dedicated DVR/NVR enclosures. However, it's important to note that it's a used unit with an expired manufacturer warranty, which introduces a level of risk compared to a new drive. Given its 'used' status and lack of warranty, the price should reflect that.
