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

OCZ Throttle memory stick - has USB and eSATA I/F
eSATA I/F
[root at 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
