If you speak about minutes, then the compression progress is taking all the time.
The interface should not affect the speed at all. If it does, then some of your drivers are baaaaaaaad [/B]
Yes, every hdd can do about 30mb/sec without too any problems (assuming the drivers and settings all are correct), but it seems like these PATA->SATA convertors can be the cause of some problems. We've had a couple of those at the office (no name convertors, pretty cheap stuff) and they made the performance suck. That's why I suggested this to be a possible cause...
This could be a driver issue, yes, as he is doing the same process twice, but when connected to SATA there is quite a differnce in speed.
If the compression goes slower when connecting the HDD to the SATA interface, there must be some explanation for the lower availability of CPU cycles. Maybe UDMA isn't enabled for the SATA channel?
