The Vizo Ares II is a convenience product that makes installing the latest 2.5 inch hard drives into a desktop a breeze. Since most of the new solid state drives are hitting the market in a 2.5" package, the demand for such a product is there. I can tell you, the Ares II does make life much easier for what it was designed to do.
My only complaints for Vizo would be that they didn't include SAS support with the Ares II and the high cost at this time. At close to 60 USD the convenience factor really starts to fade if you are not looking to hot swap drives. There are other products on the market that perform similar and the price of those units are around the same price, but I would like to have seen Vizo really break the mold and come out with a solution that costs around 20 Dollars less.
