[GRLUG] Enterprise hard drives

[David Pembrook]

I must say in defense of the warranty... I sent in a dead 160 and got a 
nice 250 back.. better than the trash can. You'll find cheep drives with 
less than 3 years, try 1 year.

I won't argue the hardware vs software raid but I'm sure I could find a 
suitable page on the net with just as many arguments against software 
raid. This sounds like the beginning of a religious argument so I will 
refrain LOL.
