Re: 500GB Seagate Cuda Question.

Hey xguntherc,

I can't really answer your question on a technical level, but maybe on a practical one. I have got two raid 0 disks each made up of 2 500 GB HD's each, two Seagate 9200.11's and two WD Caviar SE16's. Both pair are SATA 300 or SATA II or whatever you young people are calling it these days. That is, both supposedly capable of moving data at 300 MBps. (Which isn't equal to 3 Gbps, but close. Have they just given up on accuracy of expression?) But, transferring files from one Raid to another (which I guess is about the fastest thing I can do off of the cpu bus), the best throughput I have ever achieved has been capped by 90 MBps. A pretty far cry away from the mark, no?

That's as close as I can come to answering your question, some food for thought. You know, the USB 2.0 standard calls for a top throughput of 60 MBps, and until recently I never found a single device that actually reached that speed. I got a nice 4 gig zip stiick that will almost do that, downhill only, still only about 20 uphill. My guess is that these HD's might reach the SATA 300 speeds on the next-gen planars, the 1333MHz busses. But it's an ill-informed guess.
