Does performance vary with external hard drive enclosures?

[Ravynmagi]

I've been thinking about replacing my eSATA hard drive enclosure (blew up my last one by accidentally using the wrong AC adapter, oops).

Typically when buying one I looked what cooled the best and then the price.

However something I'm curious about... is there going to be much variance in the transfer speeds from one eSATA enclosure to the next?

I very much doubt it, since eSATA is basically just a pass-through to the motherboard's SATA controller?
