Many of us slightly older folk will still remember the humble floppy disk which was the computing industries first real mobile storage media for the mainstream user and when first introduced was an ideal way of transferring data across computers, as long as you did not mind formatting the disk or re-writing it a number of times because of corruption on the first few attempts.

USB 1.0 which was first introduced in 1996 was still an emerging standard so if we had a larger file we had to span the data across many floppies which I remember was a real pain at the time.

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.

Fortunately the USB (universal serial bus) standard was rapidly gaining ground and it was not long before a new breed of mobile storage hit the market which was of course the humble memory stick also affectionately called a thumb drive. These simple plug an play devices could hold a heady 2,4,6 or even 8mb of data (ok don't laugh) and data transfer speeds of 12mbps which although slow by modern standards was in fact blisteringly fast back then.

The business computer 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

The emergence of USB 2.0 and hi speed USB was a bit of a debacle for many consumers however as many USB pen drives and PCI cards were sold at the time claiming to be USB 2.0 but it was not made clear that the devices still only had the transfer speeds of 12mbps as opposed to 480 mbps.The problem was so widespread that many countries trading standards bodies were involved due to consumer lobbying for clearer packaging.

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 humble and originally very expensive thumb drive really took the market by storm and capacities rose to become greater than some people still have on their old computers, and it is now estimated than in excess of 150 million flash drives will be sold a year which of course is only the tip of the iceberg when you consider the estimated 6 billion plus USB interfaced devices in circulation which is growing at a rate of 2 billion per year.

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 drive 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.

The USB 3.0 standard has now been rolled out and accepted by most mainstream technology players but it may be still be some months before we see any consumer based products or reasonably priced motherboards supporting this latest standard.
