Alex,

How does the 3ware controller do in heavy writes back to the database?
It may have been Josh, but someone said that SATA does well with reads
but not writes. Would not equal amount of SCSI drives outperform SATA?
I don't want to start a "whose better" war, I am just trying to learn
here. It would seem the more  drives you could place in a RAID
configuration, the performance would increase.
