CCTV Hard Drives

Which hard drive does a CCTV recorder need? One built for continuous writing, and that is a surveillance drive such as the Seagate SkyHawk or Toshiba S300. This range runs from 500GB to 18TB in 3.5 inch SATA, with enterprise and NAS drives listed for larger servers. Pick the capacity by the largest drive your DVR or NVR accepts.

Choosing a CCTV hard drive

A recorder writes video all day and night, so the drive has to cope with continuous writing. The surveillance drives in this range are the Seagate SkyHawk and the Toshiba S300 and S300 Pro. The other 3.5 inch SATA drives listed here are desktop, NAS or enterprise models. They fit the bay, but they are not made for a recorder, so we do not recommend them for one.

Pick by capacity

Look up the largest disk your DVR or NVR accepts in its manual before you buy, and check that it has a free 3.5 inch SATA bay. Then choose a size from the capacity pages, such as 1TB, 4TB and 6TB. How many days of footage a disk holds depends on the number of cameras, their resolution and whether the recorder records all the time or only on motion.

After fitting

The recorder will usually ask you to format a new disk. Formatting erases everything on it, so only do it on a drive you have just fitted.
