Hi Rob,
What Andy said pretty much.
My 2p on a few things:
1. Go for some good branded SATAs that give you good £/G. When I was a
sysadmin I would choose SAS for their performance and lower failure rate
(MTBF) when building pizza box servers - you don't need that robustness for
a media server.
2. not sure sorry.
3. I run a media server (Compaq SFF PC) with 2 x 2T USB2 HDDs on Debian
Squeeze. Yes they are nice and economical and fine for serving even HiDef.
They also spin down when not in use so are good on electricity use and
noise. However I will go with SATAs and a Drobo or HP miniserver when I
outgrow this. If your network is Gigabit (or will eventually be) then it
will be the disc i/o that will be the bottleneck when doing large transfers
or backups. This became a bit of a pain after a while but maybe I am just
impatient. I would still choose SATA over USB3 as I perceive the SATA
kernel drivers more "battle tested".
The "spurious IDs" are prolly the file system IDs which are set when you
create the ext3 or 4 filesystem or RAID partition. They then keep that ID
permanently until you reformat. As mentioned, chuck them in fstab instead
of the device ID and then you can relax when doing maintenance when a HDD
needs to be replaced or you recable.
see: tree /dev/disk/by-uuid for the mappings
Hope that helps!
