Seagate has launched an 8TB disk drive for surveillance use, enabling up to 6PB of CCTV data in a rack.
This is a 3.5-inch form-factor drive and joins the existing set of 8TB Archive, Enterprise Capacity, Enterprise NAS and Kinetic disk drives. It follows on from the 6TB model announced in September last year. That had 6 platters and a 642Gbit/in2 areal density.
Seagate says the 8TB disk has 1.33TB/platter, which we calculate to mean about 854Gbit/in2 IT comes in 1, 2, 3, 4, 5, 6 and 8TB capacity points, and features;
- 7,200rpm spin speed
- 6Gbit/s SATA interface and up to 256MB cache
- Up to 230MB/sec sustained transfer speed for 8TB capacity; 180MB/sec at lower capacities
- 64 cameras supported
- Rotational vibration sensors enabling it to work reliably in 8-bay and larger enclosures
- Designed for 24 x 7 operation and up to 180TB/year workload, the same as the shingled 8TB Archive drive which spins at 5,900rpm

From the same source as above: "the failure rate of enterprise drives is actually higher than that of the consumer drives." [backblaze.com]
