Harddrives 10k vs 15k

[C.News]

I have the option on a hp raid5 server running win2k3 as follows
3 146gig 10k hard drives at raid 5
or 3 72gig 15k hard drives at raid 5.
the price for both options is equal. Given that storage space is very
imprtant to us
I am inclined to go with the 1st option.
Question? how much will this hinder performance comared to the 15k option.

Since you're going to have 66.6% storage efficiency, choose the first
option. Performance differences between 10K and 15K hard drives are not
large, in many instances.
