500GB Storage — SATA Drives and SSD Job Lot
This range covers four 500GB-class 3.5" SATA hard drives plus one Dell enterprise SSD job lot (3x 400GB, 1x 480GB, 2.5in SATA 6Gb/s). It suits engineers replacing a failed DVR/NVR disk or building out low-channel recorders where 500GB matches the retention target.
The 3.5" SATA drives
Four 500GB SATA hard drives sit in this bracket: Seagate, Toshiba, Western Digital, and one unbranded 500GB unit. All are positioned for 24/7 continuous recording duty, the workload profile typical of CCTV DVR/NVR storage.
The Dell SSD job lot
The fifth SKU is a Dell enterprise job lot — three 400GB and one 480GB 2.5in SATA 6Gb/s SSDs, sold tested. This is a different form factor and capacity mix to the 3.5" drives, so check chassis bay size (2.5in vs 3.5in) and interface before specifying it as a recorder disk.
How to choose
- Continuous recording duty: the four 500GB 3.5" SATA drives are the direct fit for DVR/NVR retention at this capacity point.
- Bay size: 3.5" drives need a 3.5" bay; the Dell SSDs are 2.5in.
- Interface: all listed drives use SATA, but confirm SATA 6Gb/s support on the target recorder for the SSD job lot.
- Brand preference: Seagate, Toshiba, or Western Digital where a named brand is required; unbranded or Dell where it isn't.
