Using eSata for the first time not AHCI

Vantec NexStar eSata USB Dock

When you start messing around with hard drives, it becomes apparent at some point that you will need an external one.  These days of terabyte (TB) storage you begin to realize that USB 2.0 just won't cut it for drive copying.  Thank goodness for the eSata option, but read on for a recap of my first time.



My motherboard the Asus P5B-VM supports SATA via it's Intel chipset, but it seems that the eSata port was a different story.  For that I had to enable the JMicron controller via the BIOS-Advanced Tab.  Even then using the AHCI option didn't work, instead I had to choose BASIC for the controller mode.

Maybe it's the device I'm connecting it to which is the Vantec NexStar Dual Dock Hard Drive Bay.  Either way it works for me now.  But before then I also had to download the current Windows Vista driver and buy a longer eSata cable than the one included with my dock.  All Fry's Electronics had was a blue colored one from Link-Depot.

Since going eSata (the Vantec device handles both interfaces and 2.5" or 3.5" drives) I've enjoyed the speed bump.  From what I've heard USB 2.0 has a theoretical speed of 480 Mbit/s versus eSata's 3,000 Mbit/s.  Try it and see.
