from the just-a-big-drive dept.

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

    WTF does that even mean? How does a hard drive know what type of data you are writing, much less how many cams? And since one cam can easily produce 10x the data of another, "a spy cam" is hardly a meaningful unit of measure.

    It doesn't mean a goddam thing, of course. It's bullshit marketing from a foundering shitty company. It sounds like it would be perfect for server (so-called NAS, another bullshit marketing term) use, if it wasn't a product of Garbage, Inc. Why should hard drives be any different than everything else in this failed society. It's all a vast race to the bottom.
