This four slot microSDHC to CF converter can take up to 4 16GB microSD or microSDHC cards that run in a RAID configuration.
As microSD is a slower format, the RAID system actually bumps it up to the speed of a compact flash card. If you are using microSD then it is important to note that the capacity will be limited to 2GB per card.
