[Gllug] RAID Partitions

[Amias Channer]

Hello all ,

I am advising on the build of a new server at the moment and was wondering if i could check some
assumptions against you collective experiences.

The client wants to have RAID in is interested in a LSI MegaRAID Ultra320 .

Would i be right in thinking that if one of the drives from a mirror is pulled it won't be 
properly readable by anything else but the same type of controller due to a proprietary format ?

If another machine had a Ultra320 card could it backup and restore with dd ?

Also are 15k rpm discs really worth twice the cost or 10K ?

TIA
