Hello :-)

I've come across a deal where by I can either buy two identical 20GB 
drives, or a 20GB drive and a 40GB drive for the same price as the two 
20GB's. I was intending to use the drives for a RAID 1 array and have 
read that ideally the drives should be identical, but it is do-able with 
different size drives.

Obviously as both options are the same price I would like to get more 
for my money and get the 40GB and 20GB drive, rather than two 20GB's. 
This should also give me the option of buying only a single 40GB drive 
later on for cheap if I need to bump the space up a bit, rather than 
buying two drives.

Simple questions really I suppose. Is having two different size drives 
going to work? Is it going to make configuration trickier in any way? 
Are there any disadvantages (other than I will be losing out on 20GB on 
the 40GB drive, and that it's only going to be as fast as the slowest 
drive I imagine)? I've never ever touched vinum before!

Thanks in advance for any advice / comments,
Mark
