[dba-Tech] Replacement Hard Drive for Raid 5 Array

Thanks Arthur.
It's a Dell so I'm hoping it will be fine. I'm not so much worried about
speed, I just want to make sure we can keep the server running in case
something happens.

It depends most on what RAID driver you have. With something like HP for
example, you will have no problem. Some of the cheaper drivers, not so
lucky. What will happen, however, is that the 15k RPM drive will only run at
10k.
