This tiny accessory from Japan's Sanwa Supply might come handy for boosting system responsiveness on the cheap, using the Ready Boost flash-drive caching feature available with select versions of Windows. The 800-TK021 from Sanwa is a small blue PCB, which fixes itself to the motherboard on one end, using a standard USB 3.0 front-panel header, and gives out two USB 3.0 type-A ports.

The ports can then be used to stash away discrete USB 3.0 storage devices (such as flash-drives, DRM sticks, HDDs, USB 3.0 portable SSDs). One incentive is using a discrete flash drive to speed up system responsiveness using Ready Boost. On sale, the 800-TK021 is priced at 780 JPY (US $9), it could be distributed under different labels, in different markets.
