Zalman ZM-VE300 External Hard Drive Enclosure Review
 

"The ZM-VE300 is a great tool for having portable data and could save some space by no longer needing disk or disk drives. That being said, it is still something that most PC users would not need or use often, but for those who do need both an external hard drive and the ability to mount ISO files and use a virtual optical drive, there are not many options on the market."
