I keep on intending to add a page for the smartctl information sections
from various drives, just haven't got round to it ...

There seem to be three main classes of raid drives out there, WD Reds,
Seagate  NASs, and Toshiba N300 raid drives. Everybody seems to buy
Reds, I've only recently seen NASs, and the N300s come with 4TB the
smallest drive. They all seem to cost about 50% more than the basic
desktop drives, but that's still amazingly cheap ...

Cheers,
Wol
