Discussing spindle count vs. rpm for overall performance. Building a HP ML350 G6 ESXi server that uses 2.5" SAS drives.
For slightly less money than as using 10k RPM hard drives, I can get twice the drives/spindles/capacity if we went with SAS 7200rpm drives.
I would believe that twice the spindles will increase IO performance, fault tolerance and double my storage capacity. The only downside seems to be less free bays for the addition of drives in the future.
Is there anything I'm not considering?
