USB Flash Memory storage devices are a practical and highly portable method of storing and moving data between places. Flash Memory is highly practical for this task as it has no moving parts, supports fairly large storage and if used properly has very little chance of failing in any serious manner.
Recently though the reliability of these devices has come under a lot of scrutiny as the failure rate of what is normally very reliable technology has escalated to previously unseen levels. Data recovery companies around the world are fielding increasing number s of enquiries and have geared their operations to cope. So what is the problem here?
USB storage devices are also dropping in cost all of the time. They are growing in popularity at such a rate that the number of devices shipped in 2007 was double that shipped in 2006. By the end of 2008, annual sales are estimated to be in the region of 300 million shipped units.
With the higher number of units in the market place it goes without saying that that the actual physical numbers of failures of portable storage devices will increase, double the units = double the failures. However along side the number of failing units of more concern is the increase in the ratio of failed units that is being seen.
So why is it that a storage media famed for its reliability fail in such high numbers? Well in about 98% of cases it is not the Flash memory that fails, in fact, following a failure it is not uncommon that the NAND memory chip within the USB device is found to be in perfect working order.
The failures are normally attributed to poor manufacture quality by mushroom companies in Korea, Taiwan, Singapore and China. These devices often make their way on to the market as unbranded devices, however there are huge problems with fake devices as noted by a leading and respected UK Based Data recovery company in this article:
These fake devices often take advantage of the consumer by reporting much higher storage capacity than is actually available which is very misleading right from the off. Another problem here as well is the cost , yes they are cheaper but what are you actually getting for your money? The manufacturing process can only go so far and that only leaves one option, cheaper and substandard components!
The best advice that anyone can give you here is to buy branded devices if the cost is affordable (which it generally is). And also ask your self this question, is the risk of losing all my data really worth risk of saving a relatively small amount of money?
