20-pack 8 TB surveillance drives
This bulk package contains twenty 3.5-inch hard drives, each offering 8 TB of storage and spinning at 7200 RPM with a 256 MB cache. They are built specifically for continuous video-surveillance recording workloads.
Check SATA ports and bay count
Verify that your recorder or server has enough free SATA 6.0Gb/s ports and physical 3.5-inch drive bays before ordering. Each unit measures 1.03 inches high, 4.00 inches long and 5.79 inches wide, so confirm rack or chassis clearance matches those dimensions.
Fits multi-bay NVRs and storage servers
The drives slot directly into standard 3.5-inch trays and connect via SATA cables, requiring no special controllers. Deploying twenty drives at once fills a large array in a single step, freeing you from staging multiple smaller shipments.
