I've used external drives on Linux systems, using either USB or FireWire
interfaces, and have had no trouble with using them as FAT32, NTFS, or
reformatted as ext3. It all depends on what you plan on using it for,
and where else you might connect it. (Just as John suggested above.)

Also, as Bill mentioned, the BIOS is not an issue if you're not going to
boot from it or use it with an OS that needs BIOS support for I/O.
(Linux doesn't.)

I've found that not only reliability can vary a lot, but performance
too. So, you might want to check online first to get good technical
specs., reviews, etc., before you buy.
In particular with USB interfaces on these external drives, even if
they're USB 2.0 rated, it doesn't mean you can get the maximum
throughput that USB 2.0 would allow. Some of them are quite a bit
slower than that. If you'll be transferring a lot of data, look for a
drive that has good I/O performance. (I'm not familiar with either of
the two you mention above, nor really any of the current crop of 1TB
external drives, so I can't offer specific recommendations.)
