Tyan Trinity KT400 S2495 Performance

Now that the new motherboard is finally bedded in, it's rather enjoyable compared to the old motherboard. On the old box, the fastest that the Promise FastTrak100 TX2 RAID1 array would every transfer data was around 5-6 MB/s, if it was feeling perky. Sometimes it would degrade down to only 2-3 MB/s. (However, I blame a lot of that on the PCI Latency issue.)

Same drives, same RAID card on the new motherboard easily handles data rates upwards of 20 MB/s, copying from point to point on the drive usually averages 10-15 MB/s. And I've seen peak rates of 30 MB/s. As a comparison, my video cap box with a 5400rpm ATA/100 drive and a 7200rpm SATA/150 drive can hit 32-36 MB/s when copying video files from one drive to the other.

So, even with all of the nuisance of getting everything installed properly, it seems to be performing up to expectations and is turning out to have been worth it.
