I would totally agree that buying separate "box" and "disk" is a
better plan.
I would probably go further and say buy an eSATA enclosure, separate disk
and a USB to eSATA converter

Then comes the problem mentioned earlier - what chip is in the converter?

My Lindy eSATA adapter shows up as 13fd:160e Initio Corporation
The only chip on their web site is INIC-1605
However 13fd seems to be Micro Science Inc not Initio Corporation
which is listed as 1101

In practice my machine will copy a 2.4GB file
from int SATA disk to ext SATA disk at approx 50MB/s eSATA
and 25MB/s with the USB/eSATA adapter

OT
OCZ Throttle memory stick - has USB and eSATA I/F
eSATA I/F
[root naxos ~]# hdparm -t /dev/sdb1
/dev/sdb1:
 Timing buffered disk reads:  268 MB in  3.00 seconds =  89.28 MB/sec

USB I/F 152d:0602 JMicron Technology Corp
/dev/sdb1:
 Timing buffered disk reads:  102 MB in  3.05 seconds =  33.48 MB/sec
