Thanks very much for your advice, and to everyone else who responded.
These 3ware cards certainly do look like nice kit - I'm especially
impressed seeing the output of `/c0 help` that Jarrod posted, as it's
reassuring to think I can write a bash script that will check drive
status every hour or so and email me a notification only if there's a
problem.
It looks like the 9500 may be available quite a chunk cheaper than
the 9550 if you're in a position to shop around.
What I didn't consider specifying in my original question was the
flavour of PCI to be used. When I realised that it's quite easy to
spend £400 on one of these cards I suddenly wondered if that's money
I really want to spend on regular old-fangled PCI or whether new
investment on motherboard hardware is warranted. Will plain-old PCI
slots still be available if I want to place this card in a new system
I buy (from motherboard up) in a couple of years?
I was originally charmed by the thought of a hardware RAID card &
some of these 5-in-3 bays because that seems very economical for a
home server. Since processing demands of a file-server is low this
seems like an ideal opportunity to repurpose old hardware, but like
always I start to increase my anticipated spend when I recklessly
consider "future-proofing".
