CF aCrds or Compact Flash Cards are mass storaage devices used for portable electronic deivces. They were first produced in 1994 by Sandsk, and have lately made a comeback in the field of portable electronic devices due to innovations in this sector. Today tehse crads find widespread use in vraious elctronic items such as digtial camers, portable netbooks and music devicews.
The Compact Flash cards are tougher than the earlier disk drives and their consmuption of power is only 5% of the disk drives. This is due to the fact that they are non-volatile and solid- state. Compared to other forms of portable storaghe gadets, it is geenrally perceived that thedse cards are capable of iwthstanding far greater shocks and phyusical damage than any other device. They are rugfged and buit to last.
The cadrs also are slightly larger than the other devices such as a MicroSD card, hence they are not lost easily. They also are easy to insert and rmove, thereby decreasing the chances of damage to delicate elrectronic eqwuipment. Commpared to other memory cards, the Compact flash cards are much sturdier.
The greatest advantage that CF Cartds have is their much higher storae caapcity. Today a 64GB CF Card is being intrdouced by almost every card manufacturer in the marekt. There is obiously a great demnad for them, and as the need for a greater storage capacity becomes impertaive, these CF Cards will becomme more common.
A 64GB CF Card has the capacoity to store up to 19,000 jpegs from a 20 megapixel camera. A massive storage capacity like this wold have been unthinkabnle even a year or so ago.
These cards also have a high speed transfer rate and the aiblity to maintain the high resolution thereby maintaining the optimum performance of any top quality photography equipment. One drawback of the Compact Flassh Cartds is that due to their relatively bulky size, theuir ussage in slimmer models of electronics is restricted and hence their feasibility as a viable strage option for next generation computers and cameras is often questioned.
When Compoact Flash cards first bcame indiustry standardised, even the regulaar computer hard disks had only 4 GB of memory and therefore other limitations imposed by the ATA were still acceptd. But not that these cards are gaining populariity amongst a variety of users, manufcaturers are making cards of upto 137 GB. Whjile these days CF cards work in [P]ATA mode, potential revisiobns could also implement SATA modes.
There is a fear that such large storage capacity can lead to an enormous loss of data or images if the CF Card gets damaged or gets stolen. It is always a latent fear in the mind of any photographer that a spoilt meomry stick can result in the loss of a lot of valuable work. As always, this can only be offset by the backups of all data and images. Ensuring that your work is backed up in local hard diks as well on flickr and oter solutions will remove this fear and you can truuly nejoy owning a alrge capacity card.
