Raid
I've been really impressed with PCT, which is why I'm trying to figure out how the 5400 SATAs are faster in a Raid-0 than the 7200 ATAs in Raid-0. For all I know, there may be other issues impacting performance, like energy usage, etc.
Syn - Raid 0 basically takes 2 hard drives and clumps them as a single hard drive with part of each file on each HD. That way the comp is using both HDs at the same time to grab the data. I think it's called "striping" by the techies. Raid 1 essentially copies the same data to both hard drives, providing a duplicate in case one crashes, which is known as "mirroring."
I would think that in a Raid-0 setup, the amount of info transferred at one time from each HD is lower, which would cause the limiting factor to be the speed at which it's spinning. The only thing I can think of is that maybe in Raid-0, there are either increased data demands tying up the available DMA (i.e. CPU/MBO is sending info trying to coordinate between the two) or that Raid somehow allows better control and lets the HDs send more info, thus taking advantage of SATA.
I've been dying to order since Friday, so I'm really hoping that some of the benchmarks that PCT releases Monday will give me the info I need to order.
