The Thermaltake BlacX USB is a convenience product and is one that enthusiasts have waited a long time for. I personally have used a USB external hard disk carrier many times without the cover on it so that I could quickly swap drives around, and I am sure many reading this have done the same thing. The BlacX makes swapping drives around easier and "less dirty".
The only thing that has me frizzled with the BlacX is that they have two versions named the same thing, yet with a big feature loss on one of them. I think more than a few users will accidently order the USB only version when trying to get the USB + eSATA. Since Thermaltake already has an upgraded model (also only with USB?); the BlacX SE with four USB ports, the BlacX without eSATA could have been named the BlacX LT (for Lite) and in the long run a few headaches would have been eliminated.
Overall, the Thermaltake BlacX is a remarkable product that I will not be able to live without from this time forward. No more digging around for a flashlight, removing a side panel and looking for an extra SATA cable just to dig a file off a drive, and I think people who routinely work on other peoples computers will really benefit from the BlacX.
Thermaltake has one of the best retail and e-tail client lists in the PC accessory market, with nearly all of their products sold locally in every major city in the USA. Newegg has already started to sell the BlacX for less than the MSRP, and picking one up at less than 40.00 US Dollars is a bargain.
