I must not have the 'right components'. I used a Thermaltake blacX in eSATA interface to raw sector-by-sector clone a 250GB Seagate to a 250GB WD drive. I've lost the HDTach and HDTune numbers for SATA vs eSATA, but my results for eSATA vs SATA throughput for the cloning operation:
- 2.5 hours @ eSATA with the blacX docking station.
- 2 hours @ SATA with the drive bay docking device.
AHCI mode vs IDE mode may have some benefit besides hot-swap, but my OS was installed in IDE mode and I didn't want the hassle of OS reinstall in AHCI mode.
Do you think AHCI mode @ eSATA would make up the 20% effective throughput loss I experienced with eSATA @ IDE mode?
Ok I wanted to test my comment about ESATA should be as fast a SATA so I ran tests with my system and using my blackX and 2 Antec MX-1 units so heres the results..................

Seems like HD Tune so no major slowdows with internal and extrenal drives although I didnt test the 1.5tb drive internally the test seem good performance wise on ESATA devices.......
Check my rig for system information
