I have a Western Digital WD5000BEVT 500GB 2.5" Hard Drive SATAII
5400rpm 8MB Cache - OEM Scorpio Blue hard disk.

I wish to purchase an external USB case in which to place this disk.

I am looking at Safecom products 2.5" SATA / IDE HDD
USB 2.0 Enclosure

model SU2-25SJA

<http://www.qtds.com/products.asp?recnumber=1058>

and model SU2B-25SPJA

<http://www.qtds.com/products.asp?recnumber=1059>

The former says it supports hard disks of capacity up to 320 GB
and the latter of capacity of up to 160 GB.

What is it which places a limit on the capacity of the disk
which can be used with these enclosures, and thus why would
these not work with the 500 GB disk?

I'm not sure, but I can tell you that a cheap "Kingwin" adapter (no
case) that I got on sale for about $12 will work for at least a 320GB
drive, although the box does not indicate that there is any size
limitation at all. (320GB being the largest WD Black laptop drive
that was available when I bought it.)

One of the problems I find with these recent
external drive boxes
is that the cables are very stiff and the
connectors are the same size
as for earlier flexible cables. That puts a lot of
strain on the connectors -
possible trouble ahead.

If your 2.5" drive is only for at home use for backups, etc,
consider something like the Therlmaltake BlacX. If you're
not familiar with that device, it's an external plug in drive dock.
The unit I have takes 3.5" or 2.5" disks and has USB2, and
eSATA interfaces. It's great for backups, cloning drives, etc.
Using the eSATA interface, it can also be used for booting OS
drives.

I don't know what its max drive capacity is, but it works with
a 1TB drive. The BlacX has a built in interface for USB2, but
for eSATA, the drive is controlled directly by the motherboard
eSATA controller. It comes with a power brick, and cables
for both interfaces. This device makes it easy to use multiple
2.5" bare drives as compact backup media. At $100 a drive for
500GB drives, it may seem expensive, but not when you consider
that not much over 10 years ago tape backup cartridges of much
lower capacity, and reliability, could cost that, or more.
