Best HD for back up/speed/reliability?

[frankyk]

I am considering a few hard drives for backup of my data:

1. 750 GB or 500 GB WD My Book (External HD)
2. 750 GB WD SE16 Caviar
3. 750 GB 7200.11 Seagate
4. 640 GB WD
5. 750 GB Samsung Spinpoint

anyway...

which is the best one for hard drive backup and just overall speed/reliability? I am considering putting these HD's in an external enclosure also. Any recommendations on those?

depends on what type of external enclosure you're going to get. If you're getting usb then there is no point in being fast. eSata is another story though.

For speed, the WD 640GB drive is about the fasted 7200rpm drive on the market but there isn't much to be said about reliability yet since they haven't been out too long.
