The Western Digital WD5000AAKX is a 500GB internal hard drive in the standard 3.5-inch size, with a SATA interface and a 7200 RPM spindle. Western Digital notes that its Advanced Format technology lets the drive reach a larger capacity from the same media.
The maker's text also lists noise-reducing technologies, compatibility testing in its F.I.T. Lab and Acronis True Image WD Edition software to download. The product data describes it as suited to 24/7 operation, external storage and backup servers. It is a general desktop drive, not one sold as a surveillance or NAS model.
For a working CCTV system the usual job is a like-for-like swap: the old drive has started to fail, the recorder reports a disk error, and a drive of the same size and connector goes into the same bay. 500GB keeps a short history for a small number of cameras.
The drive is a plain storage part, so it does not add any software or settings of its own to the recorder. Before you order, check your recorder's manual for the largest drive size it accepts and whether it lists the drive type. Fit the drive with the recorder switched off and mains power removed, then format it from the recorder's own menu so it can start recording.
Other 3.5-inch drives in the Storage category give more room if your recorder can use them.
