"[...] a 3 Gbit/s signaling rate was added to the Physical layer (PHY layer), 
effectively doubling data throughput from 150 MB/s to 300 MB/s."

By my calculations, that should come out to about 2 1/4 minutes for a 40 GB 
file.

and

"Backward compatibility between SATA 1.5 Gbit/s controllers and SATA 3.0 Gbit/s 
devices was important, so SATA/300's autonegotiation sequence is designed to 
fallback to SATA/150 speed (1.5 Gbit/s rate) when in communication with such 
devices. In practice, some older SATA controllers do not properly implement 
SATA speed negotiation. Affected systems require user-intervention to manually 
set the SATA 3.0 Gbit/s peripherals to 1.5 Gbit/s mode, generally through the 
use of a jumper."

Are you piping this through gzip or some other kind of process like that?

Does anybody know how long it takes for SATA drives to transfer data?

It's taken almost 3 hours to transfer about a 40GB Exchange private
DB, and I'm wondering if there is a problem or if it's a problem
related to the previous error.
