The new CompactFlash adapter from Photofast can hold four 16GB microSD cards running in RAID. This makes the slower microSD format as fast as CompactFlash by striping data across all four microSD cards at once.
For those that don't need 64GB of storage, the CR-7100 will hold one 16GB microSD, while the
CR-7000 holds one 32GB SD. The 7200 will be available for $30 and the 7100 and 7000 for $25, all in July. [Photofast via Akihabara]
