The nostalgia factor might be considered a good thing, then again... ;-)

Theo didn't mention how much storage he needs or the number of physical
drives needed. He did in another message mention that keeping his
basement cool was one of the reasons why he wants to run the single 18gb
drives. It's his/their call. 

If the primary goal is just getting more reliable storage for machines,
it's tough to beat the 7 to 25 dollar price tag. For the price two
st318416n disks at $175 he can have 50 of the more nostalgic drives.

Maybe some combination of the two models would be a more cost effective
fit?

I don't live too far from the place selling the disks, so if necessary I
can pick them up and ship them off.
