Secure flash drives were first brought to the market in the year 2000. They had a capacity of 8 MB which was five times that of floppy drives. Another advantage of secure flash drives was that it had no moveable parts which meant no wear and tear due to movement. Actually the word ‘drive’ was a throwback to the disk type storage devices. Strictly secure flash drives have no drives.
From an insignificant memory , secure flash drives are now available with much larger capacities .In fact secure flash drive with 256 MB memory and smaller are being phased out and by 2009 those with 512 MB capacity flash memory will also become history . Higher speeds, faster access times and more reliable and secure flash drives are appearing in the market with capacities of up to 64 GB.
The limitation concerning restriction in number of write instructions is also being addressed. As on date secure flash drive cannot be used as a regular hard drive because of limited write instructions.
Secure Flash Drive Developments
Security is a major concern for a secure flash drive. Wide ranging developments are taking place and SanDisk as a pioneer in this field is spearheading this initiative. SanDisk has introduced secure flash drive named SD Plus, which is a SecureDigital card with a USB connector. SanDisk has also come out with a new technology to permit controlled storage and usage of copyrighted materials on flash drives, primarily for use by students. This technology is termed FlashCP.
In future secure flash drives will fully replace traditional hard disks . This will bring several benefits. One of the main reasons for failure of hard disks with drives is moving parts. Due to this scratches and damage to the media are inescapable, while secure flash drives do not have such a limitation. Access speed also becomes faster with secure flash drives. The small and compact size of a secure flash drive makes it a favorite with travelers and professionals on the move. As secure flash drives become even more compact, their usage will increase many fold. This popularity will require further strengthening of security features. Challenges to meet secure data storage requirements, retrieval and recovery in case of compromised situations will become increasingly more complex. As we look ahead to the future, product companies like SanDisk will develop secure flash drives which will be faster, carry more capacity and will provide a high level of security.
