500GB hard drives for CCTV recorders
A 500GB hard drive is a straightforward, entry-level storage option for a DVR or NVR recording system. This range includes 500GB 3.5" SATA drives from Seagate, Toshiba and Western Digital, plus an additional unbranded 500GB SATA option — four products in total, all sized for use inside a CCTV recorder rather than a desktop PC.
These drives are built for the way recorders write data: continuously, in a loop, overwriting older footage as new footage comes in. That's different from typical desktop use, so a drive intended for 24/7 recording is generally a safer choice than a standard consumer drive for this job.
How to choose
- Brand: Seagate, Toshiba and Western Digital are all represented here as like-for-like 3.5" SATA options — pick based on your preferred brand or existing recorder setup.
- Capacity fit: 500GB is a base-tier size; how many days of footage it holds depends on your number of cameras, resolution and frame rate.
- Recorder compatibility: check your DVR/NVR accepts a 3.5" SATA drive before buying, as connector type and physical bay size must match.
500GB — frequently asked questions
Will a 500GB drive fit any CCTV recorder?
Only if your DVR or NVR has a 3.5" SATA bay; check your recorder's manual for the supported drive type and size before buying.
How much footage does 500GB store?
This depends on how many cameras you run, their resolution and frame rate, so it varies from system to system rather than being a fixed figure.
What's the difference between these brands?
Seagate, Toshiba and Western Digital in this range are all 500GB 3.5" SATA drives aimed at the same continuous-recording use case, so the choice mainly comes down to preference or what your recorder is already set up with.
