The RAID controller that comes stock with this specific listing would be okay if I wasn’t planning on using large disks. As previously discussed, the PERC6i controller won’t see drives larger than 2TB, nor will it process anything faster than 3Gb/s. If I was using a separate NAS, then I could have stocked this machine with smaller-capacity, faster-spinning drives and RAID’d them together to get the space needed for my virtual hard drive files. This would be better practice, but hey, where’s the fun (and savings) in that?
