Western Digital 6TB WD Purple Surveillance Internal Hard Drive HDD

Overview

Recording continuously from security cameras is the job of this surveillance-class drive, which connects over SATA to a PC. A large cache buffer and a modest spindle speed suit a steady flow of video data.

Choose it for bulk storage of video footage in a PC-based system. The limit is thin detail, since the listing names no recorder compatibility and two transfer-rate fields disagree with the interface.

Who it's for

A home or small business user archiving camera video on a computer will use the capacity and the surveillance branding. Buyers who need a certain recorder model, a stated camera count or fast random access should confirm those with the maker.

Pros and cons

Performance notes

Surveillance drives are made for continuous recording, so they favor steady writing of video over fast random reads and fit recording better than everyday computing. Spindle speed and cache set sustained transfer, and heat matters more when many drives share one case.
