We have a 960 dual channel ultra wide, it's QUICK. We're using it in a NT
(ugh) machine right now with a single 18 gig raid 0. Although not a
perfect method of benchmarking, it took less than 30 seconds to completly
format the drive (ntfs) with sector testing. We actually did it a bunch
of times out of sheer disbelief. I can't wait for a working 960 linux
driver.
While I do believe the DAC960 is quick, that sounds like a bit too quick. If
NT actually read all 18GB, that would imply an I/O rate of about 600MB/second.
There's simply no way that two Wide UltraSCSI channels can do that, let alone
the disks. Not to mention that there isn't enough PCI or main memory
bandwidth to sustain that.
