Raid Controller - 1 channel or 2 channel?
I'm purchasing an adaptec u/160 raid controller for a new server. There are currently two options that I am aware of.
1st option - Adaptec 2100s single channel raid, $345
2nd option - Adaptec 3200s dual channel raid, $550
I'm only going to be using 2 drives (36 gig quantum 10k's). They are going to be in a raid 1 format (mirrored).
What are the advantages of getting the dual channel? I think it will be faster, correct? (I would have 160mb/s per drive instead of total).
Is there any redundancy advantage to purchasing the dual channel controller? And if there is, has anyone ever heard of just 1 channel going out on a raid card?
Redundancy is the thing that would persuade me to purchase the 2 channel card... The server that it's going in has a lot of redundancy... even down to dual power supplies....
All of your comments / suggestions will be greatly appreciated!
