Well, my experience with Barracudas has been good - they were my
preferred choice of drive ...

You saying Black rang alarm bells for me, and I've just looked on my
favourite sales site - it says they are DESKTOP drives!

YOU NEED TO CHECK THEM OUT WITH SMARTCTL!

Check if they support ERC etc. The Barracudas I know don't, the Reds
various people have said they do. If the blacks don't support it, then
they'll let you down when you need it. You really don't want to go raid
5 or 6 with drives that don't support it. I want to go raid 5, which is
why I'm gutted to discover I'll have to replace my Barracudas. imho
they're decent serviceable drives ...

Yup. No real point going gpt until you get to 3 and 4TB drives. Once you
can get linux running, it shouldn't care what sort of drives you have,
but if you read the gentoo wiki pages about installing on raid
(disclaimer, I wrote a decent chunk of it), you'll see what a pig it can
be getting as far as loading linux ...
