The Mini-Kart is so small you could lose it in a bag of potato chips if you're not careful. Luckily, an included lanyard helps you keep track of the wee device. Instead of the standard rectangular metal USB port, the Mini-Kart’s pins are out in the open—it doesn’t even have a cap.
The PNY drive not only sports the most capacity in this roundup, it’s also the fastest. It blew the others out of the water in our 3GB read/write test. Its read speed (361 seconds) was an incredible minute and a half faster than the Verbatim drive, and its write speed (430 seconds) was an ass-kicking three minutes faster than both the Verbatim and Western Digital models.
Koolance’s new Exos-LT is a cross between the too-expensive Exos 2 and the previous-gen Exos system. At just $200 (plus an extra $40 for a Koolance CPU block, which isn’t included), it’s the budget contender of this roundup. Of course, it’s the sole CPU-only kit in the group—if it were spec’d with extra blocks, we’d expect it to be priced like the others.
