Well that entirely depends on what level...
1. I would suggest LSI 150-6 not 3ware
Why?
Because 3ware does not make a midrange card that has a battery backed
cache :). That is the only reason. 3ware makes good stuff.
So anyway... LSI150-6 with Battery Backed cache option. Put 6 drives
on it with a RAID 10 array, turn on write cache and you should have
a hauling drive.
