I have about 30 or so hard drives that have been pulled out of brand new Dell Optiplex machines. This was due to installing aftermarket solid state drives. So I have a bunch of 500gb and 1TB drives. I have a Dell T310 server that I will be using with ESX or Hyper-V. I would like to utilize these drives in some external attached storage device for development/testing VMs. I am not looking to spend a boat load but I would like to utilize some of these drives. I do not need a ton of space. More need something that will be reliable and fast enough to spin up some VM when I need to. What is the best solution for this?
