3ware hardware is really nice, so that would be a good choice.
But... I am a bit biased: I almost always prefer software RAID over
hardware RAID. Much more flexibility to move disks between systems,
choose controller(s) you like, etc.
In theory performance of hardware RAID can be better than software RAID.
In practice, only a few hardware RAID controllers actually achieve this.
