TestFreaks posted a review on SiSoftware Sandra 2010 Portable USB Edition
Sandra is a well known and respected set of tools that will do much more than just benchmarks though, it's a complete suite of tools that can help you learn everything and anything about your computers from temperatures to voltages to even giving you information about your portable devices like MP3 players and phones. SiSoftware has recently released portable versions of their Sandra testing and diagnostic utility, it comes on a USB drive to make it fully portable so you can easily take it with you if need be, and it can be run right from the USB drive with no installation necessary.SiSoftware Sandra 2010 Portable USB Edition Review
