  • Choose capacity first. Pick by how much data you need to store and how long to retain it.
  • RPM and cache. 7200 RPM drives are faster for everyday use; 5400 RPM drives are typically quieter and cooler.
  • Check SMR vs CMR. SMR drives can slow under long sustained writes; avoid them for continuous recording or RAID.
  • Use surveillance drives for CCTV. Drives such as SkyHawk are intended for DVR/NVR recording.
