The Super Talent RBST is a bell and whistle free USB device that has been designed for use with Microsoft Windows Vista's ReadyBoost feature. ReadyBoost improves the performance of your PC without opening your case. The secret behind ReadyBoost is that it is a lot faster to access data on a USB drive than on the harddisk. Access time is what matters for this with transfer rate being secondary. Your whole memory is organized in so-called pages of 4 KB size each. As you can imagine actual transfer rate doesn't really matter for a 4 KB transfer. With a typical HDD a seek + transfer of 4 KB takes about 13 ms = 12 ms (seek time) + 1 ms (transfer time). With a ReadyBoost USB stick this time is reduced to only 5 ms = 1 ms (seek) + 4 ms (transfer). This has great potential in situations where main memory is scarce or the harddisk is busy doing other things.
Super Talent's RBST comes at a very competitive price, which makes it a no-brainer if you are unhappy with your Windows Vista performance and want an easy way to upgrade your system without doing an actual hardware upgrade. Also this allows notebooks with limited memory to improve their Vista performance without going for expensive SO-DIMM memory upgrades.
