unhappy_mage said:"Is it worth it" is the title of the thread. If you want to ignore that, find another thread. To paraphrase, get off your friggin' dead horse
The OP isn't building the fastest array EVAR OMG, he's looking to spend his money in a reasonable manner. Most people who consider raid would be better served by a single drive and an upgrade in another area.
Why is the raptor raid 0 setup so appealing to you? Scsi will give higher benchmarks, and probably have a higher cool factor too. To draw a bad analogy, "The fastest sata setup" is like "the most expensive Honda".
You're right - "Is it worth it" is the thread title - I should have saved a few of my comments for a "what is the fastest SATA setup you can have."
I AM seriously considering SCSI except for the noise they bring.
And as soon as iRAM can get more than 4GB per device, and a little more redundacy/reliability, I'm there. They are RAID0ing the iRAM's and getting exactly double the speed out of them-very impressive, but not practical - Vista will not even fit on them right now.
