💾 Recommended Hard Drive (Storage Guide)
To get the best performance from your Hikvision DS-7732NI-M4/16P, we recommend using surveillance-rated hard drives such as WD Purple or Seagate SkyHawk.
8TB – 10TB
Suitable for smaller 8–12 camera systems or shorter retention targets.
12TB – 16TB
Best for mid-sized 12–20 camera systems with standard retention periods.
18TB – 24TB+
Recommended for larger 20–32 camera systems or longer recording retention.
With 4 SATA bays, this NVR gives you much more storage flexibility than smaller 8CH or 16CH recorders.
💡 Tip: For most systems, using H.265+ and motion-based recording can significantly improve storage efficiency. Hikvision states H.265+ can reduce storage space requirements by up to 75% in supported scenarios. :contentReference[oaicite:3]{index=3}
