SD Speed Increase, which requires a rooted Android device, tries to speed up your SD card's file-transfer rates and general read-write functions by increasing the default cache size of the SD card.

All you have to do is open the app, set it to a higher cache size and hit a button. Since the cache size isn't kept after reboots, SD Speed Increase has an option to automatically reset it every time you start up your device.

As the developer advises, this app may not work on all Android devices. You may not see any noticeable differences in the SD card speeds -- I didn't -- but it's worth a try.
