Compact Flash Drive

Compact flash drive is a storage device, first introduced by SanDisk in 1994. Latest compact flash drives require no necessity to download drivers to plug and use them as compared to older ones. Latest compact flash drives have plug and play feature. Compact flash drives are portable because of their small size and has more storage capacity compared to floppy disks.

The competitors to compact flash drive are MMC/SD, memory sticks etc., which provides comparable capacity and speed. It helps in transferring data in desktop computers, digital cameras, DSLR, PDAs (Personal Digital Assistants) and so on. Storage capacity ranges from MBs to GBs(128). As the storage capacity increases, the cost increases.

Two types of compact flash cards namely, CF I (3.3 mm thick) and CF II (5.5 mm thick). Compact flash cards have non-volatile memory. It has good resistivity to physical shocks because of its ruggedness compared to traditional or older storage devices. Compact flash is present in professional grade digital cameras for storing large amount of data. Flash resembles the solid-state mechanics of EEPROM (Electronically Erasable Programmatically Read Only Memory).

Compact Flash’s interface is electronically identical to PCMCIA (Personal Computer Memory Card International Association). Therefore, CF is well established. The availability of adapters for Compact Flash to access through USB port, PC card slot, memory card readers etc., is an added advantage. Most of the platforms support it. Input and output interface devices having CF specification can communicate with any device having a CF slot like modems, digital cameras, GPS receivers, Ethernet cards etc.

Applications

  • Data is stored in a reliable manner than hard disk
  • It is faster and has more capacity than floppy disk
  • Portable and easy to use
  • Helps in transferring the data across different platforms
  • No movable parts as compared to Hard disk drive

Advantages

  • Slightly less battery consumption i.e., increases battery life slightly
  • Produces less noise and vibration
  • Risk of damage due to physical shocks is less
  • High read and write throughput
  • Accessing is faster

Disadvantages

  • Low capacity (when compared to hard disk)
  • Price increases for every GB capacity
  • Size of CF is bigger compared to SD and MMC

File Systems

Depending on the device, file system format differs from FAT12 to FAT32. In case of media, the device having capacity up to 16MB is formatted as FAT12, likewise for up to 4GB it is FAT16 and for larger than 4GB it is FAT32. A device with FAT32 capability should read and write to a FAT32 formatted card easily without problems. The flash cards can be formatted to any type of file system like NTFS, ext2, ext3, ext4, exFAT, HFS+.

USB data recovery
If you have lost data from USB drive, try recovering lost files using best recovery software like Remo Recover. Files from USB drive oftenly get corrupted due to virus attack. Take precaution while connecting a pen drive to other device that, whether it has an updated anti-virus software activated.
