We have an HP DL380 G5 terminal server that is running a mirrored 10k SAS. the hard drive usage is 99.5%. We have bought 3 15k SAS drives to replace the 10k drives, but we don't have imaging software that will work on our servers. We are going to put the 15k drives in a RAID 5 array instead of RAID 1. Does anyone have any suggestions on how to get the data off of our 10k drives and onto our 15k drives?
