Question: Does anyone know if I can install normal 2.5" SATA drives inside an HP DL360 G5 server? Right now it has 6 72GB SAS drives. I am looking for raw storage for my files SAS performance in not required.

Answer: 
You should be able use any SATA drive, but I'd consult the bare drive model numbers on HP's *[Hard Drive Model Number Matrix](http://h20565.www2.hpe.com/hpsc/doc/public/display?sp4ts.oid=408482&docId=emr_na-c00305257&docLocale=en_US)* before you buy. That'll give you a strong indication of which drives will work well in your server, and point you to any special firmware.

Old question, I know, but it took me ages to find that list.
You can use SATA drives, but make sure they are "raid edition" drives intended for use in servers, and not drives intended for use in desktops. "Raid Edition" is Western Digital's name for it: other vendors each have their own name, but this is important; it's not just snake oil and you can run into problems if you get cheaper disks.

Expect to spend about $100 for a 1TB disk of this type:

or $120 for a more recent version with a larger cache:
