I cantacted one of the guys that work with these drives about my bandwidth issues and this is the response I got:
"I actually hate the consumer benchmarks. They show overall results,
but really hide the underlying details.We have found that most motherboard SATA controllers are mediocre at best and some are downright lousy. There are two points that the MB controllers seem to fall down on. One is transfer rate, which is what you are seeing. The other is random reads.So far in our testing, the best controllers have been HighPoint 2300 series "dumb" raid boards. You can get a Pci-E 1x 4 port board for about $110 and a 4x 4 port board for $160 (try NewEgg). These boards seem to push the random read and linear speeds of the drive up to their
theoretical values. This seems to be true for the 1x board up to 2 drives and the 4x board up to 4 drives. If you have more than 4
drives, you will slow down somewhere. We have a test paper on this at:
http://mtron.easyco.com/news/papers/07-12-01_mtron-benchmarks.pdfWe have tested "smarter" boards like the LSI 8038, but the presence of an on-board CPU seems to slow things down. These "smart" boards may do
better at linear read/write speeds, but in random accesses, we have
seen 60% degradations. Now of course your mileage may vary.Now realize that we are testing raid-5 for database and server usage. All of our tests as of now are in Linux (not Windows). To be honest, raid-0 testing for the gaming user is not that interesting to us (and
no server user would ever run raid-0 anyway)."
So I guess these drives just dont work quite as well as a few of us hoped, directly off the mother board anyway. Not that I cant hadle spending a little extra dough on a raid controller, esp. after the price on these drives. It would have been nice though (im sure others feel the same way)
