The HP server I bought (ProLiant ML110 G5, to be specific) comes with an integrated hardware RAID controller, but only one hard drive (a 250GB 7200RPM NHP SATA drive) My company is on a limited budget, so if possible I would like to avoid buying HP-branded drives, as they are more expensive than if I were to just buy some decent drives off Newegg.
Now, I know software RAID supports mixed drives, but I'm not clear on hardware RAID. The ultimate solution I came to while searching was "it depends on the RAID controller". So, my question is: If I buy similar drives (250GB 7200RPM SATA etc etc) from a third party vendor and try to use them with my HP RAID controller, will there be any issues?
