If you have been around for more than a few years then undoubtedly you will remember the frustratingly painful floppy drives that used to be the only way to effectively transfer files between computers. Frustrating of course because often the floppy would not write or even more frustratingly would not read on the donor machine.

Also the USB 1.0 format was relatively new back in the day, devices that took advantage of the technology were relatively thin on the ground so if you were really lucky you did not have to get involved with larger files that often required spanning across many disks which was even more fraught with frustrastion.

But as computing power grew at a fast pace the size of files seemed to grow exponentially and the floppy drive was simply not up to the job meaning many people were left having to burn very expensive CD’s as burning technology came into play in the nick of time.

USB was making rapid gains fortunately and manufacturers were coming up with many new uses for this very user friendly (operating system permitting) plug and play capability, and the pen drive was borne not a moment to soon in my opinion. Mobile data transfer capacity rocketed upwards from a humble 2mb and it did not seem too long until the capacity of USB pen drives surpassed that of the CD.

The IT support and IT industries where some of the first serious adopters of pen drives primarily due to the fact that system tools could be easily carried on a flash drive and with the larger capacities reduced the need to carry around a number of CD disks used for diagnostics or computer maintenance utilities.

Increased capacities then drove the need for higher data transfer speeds and it was not long before USB 2.0 and then Hi-speed USB appeared and filled the need for speed

There was of course a lot of confusion between USB 2 and Hi speed USB at the time, which could transfer data at an astonishing 480mbps per second but a lot of early adopters were left more than a tad upset as industry often sold devices and PCI cards as USB 2.0 but in reality they were only USB 2.0 compliant and still had a much slower transfer speed.

The USB interface and standard is now nicely matured and USB interfaces are common across a range of consumer devices from phones to cameras and even video players although it was and still is to a degree questionable as to whether USB or Firewire would win the day as the dominant data transfer protocol.

The USB pen drive has really risen to the challenge to take advantage of the USB interface and storage capacities are enormous and far beyond most peoples requirements, What were almost in the beginning icons of your technical prowess have now become a mainstream device and sales are said to exceed 150 million units per year just for pen drives alone. The USB interface is also said to be present in over 6 billion consumers devices and this number is growing at over 30% per annum.

Increases in drive capacities has raised a number of issues across many industry sectors including the data recovery industry, which has had to evolve new USB memory recovery techniques for recovering data from these flash based devices.

It is so easy to transfer and store data on these devices that many users are really taking them for granted and not saving their data elsewhere, which is all well and good until your drive breaks or gets damaged, or perhaps the memory controller fails.

Some Data recovery companies have of course stepped up the mark and the USB recovery industry is now alive and well.

Another issue these devices have highlighted is the need for security as sensitive data (business or personal) can be quickly and easily stolen from the source. Technology has answered the problem and secure pen drives are now available and manufacturing giant Fujitsu has continued its innovation in security with the invention of a smart USB drives which even have the ability to auto erase data on a USB memory device.

As it seems with all technology every development brings us even greater speed and the new USB 3.0 standard is no exception promising data transfer speed 10x greater than current specs which will give us transfer speeds around 5Gbps.

This very fast transfer speed may of course signal the end of the older firewire standard which has been falling behind more recently.

USB 3.0 standards have been ratified and the first devices are expected to be available towards the end of the year and it will also be interesting to see if Windows 7 ready boost feature will be able to increase the operating systems performance far greater than is apparent in Windows Vista.
