Looking inside my R10 I see that I have 2 empty 2.5" hard drive slots.  I've installed many 3.5" hard drives, but haven't installed a 2.5" one before.  I was curious if there was anything specifically I should look for?  Can pretty much any 2.5" hard drive work?  I was thinking of getting this Seagate 4TB Barracuda Sata 6GB/s 128MB Cache 2.5-Inch 15mm Internal Hard Drive (ST4000LM024) 2.5 Internal Bare/OEM Drive or possibly the 5TB version of it.    Just wanted to make sure this would work before buying it.
