UDMA-E Speed

[kpeddie]

Whats the real world transfer speed(undamaged drive) between port 0 and host and port 0 and 1 on the new UDMA-E cards in comparison to my old UDMA PCI card? Been out for a while now so hopefully a few of you have them.

I have both UDMA and UDMA-E running...assuming that the drive is reading healthy:

UMDA: about 40MB/second
UDMA-E: about 90MB/second

That said, if the drive is healthy enough to clone without PC3K utility, I clone with DDI. Most drives cloning on DE are getting getting less than 3MB/second average.

How fast is DDI?

How fast is DDI?

Again, depending on the condition of the drive. I have seen speeds over 100MB/second, but usually average around 90MB/second. Assuming we are talking about DDI4 and not DDI3, which tends to peak at about 55MB/second.

hmm, ill have to change the board my ddi4 is in! Ive never seen it go above 60.
