Packaged External drives sometimes have only 1 year warranty, whereas the internal drive mechanisms you buy usually have 3 to 5 years. Also some brands (Maxtor for one) do not allow you to open the case to take out and recover data from the hard drive, if the enclosure fails - they will void the warranty if you open it.
One option is to buy a good enclosure, and put in the 'internal' drive of your choice. It takes 2 minutes to assemble. That way you have complete control of the brand and model of drive mechanism, and you can be sure to get a 16 Mb cache.
For a Mac, get a Firewire drive. USB is much slower in real world performance than Firewire (I benchmarked USB 2.0 and Firewire 400 on the same drive. A 1.3 GB file transfer was almost exactly twice as fast on Firewire 400)
No Macs come standard with eSATA ports. eSATA is an option only if you can install an eSATA interface card and can afford the extra. eSATA is useful because it reduces the load on the Firewire bus if you are using a Firewire interface. But you cannot add eSATA to a Mini, a MacBook or an iMac.
Many of the 'one touch backup' software bundles are Windows only. Check before you consider that as a factor in a purchase.
Avoid bus powered drives, unless you absolutely must have a portable solution without AC adaptors, AC powered drives are more reliable.
