| Hard Disk Drives |
| Sample Driver and reference designs have been created for interfacing an IDE HDD to a FAT file system. Also provided in the file system are caching options which are essential when using a HDD. The caching mechanisms combined with the efficiency of SFATFS and its mainly zero-copy reads and writes gives the best possible performance when implementing a HDD on an embedded system. |

MultiMedia Card and
Secure Digital Cards |
| This is probably the simplest method to add a DOS compatible file media to your embedded device. We provide a range of drivers for interfacing to SD and MMC cards including standard SPI implemented in either hardware or software. We provide hardware design information for implementing this. |
| Compact Flash Cards |
| Compact Flash cards require a more complex communication with a PC compatible media but offers performance advantages because of the wider data bus thus generally a higher throughput is achieved and in many cases a reduced CPU load. We also provide hardware design information and CPLD logic where appropriate. |
| RAM Drive |
| A RAM drive is provided as standard and is particularly useful in getting a system up and running without any hardware dependencies. |
