Anyone here tested eSATA? Is it slow?

[M A V I C]

Thanks Larry. Yeah, I'm using two Seagate 7200.10 320GB drives. One is connected internally. The external drive I've connected to an eSATA bracket which goes straight to a SATA header.

It is an eSATA+USB2 enclosure http://www.antec.com/Believe_it/product.php?id=NzA0MjIx

I'd go for one of these and replace my ATA version of the enclosure http://eshop.macsales.com/shop/enclosure..._RAID_Quad but I like how quiet the Antec is. Of course, if the Antec is going to be slow...
