5400 RPM drives for my setup... Nope. VMs would run like a dog. Same with video encoding and performance. Best off just having a few smaller cap faster drives. This won't sit too well with the media pro and Hypervisor crowd. VMs are slow enough on a 7200RPM drive... let alone a 5200 RPM drive. I plan on getting a larger capacity SSD for my VMs when I can afford it. Use a laptop (most have 5400/5200 RPM drives) and they are hella slow.
