In general, USB flash memory devices are small, lightweight, practical and inexpensive USB flash drive and rewritable memory type NAND data with an integrated USB memory interface. There are several advantages over other portable storage devices, particularly in the conservative media such as floppy disks, USB flash drive faster to collect more data and are considered more reliable than any other storage device on the market today.
ByCompared to 88.2 million USB flash drives sold in 2005 and 115.7 million were shipped in 2006, Gartner Dataquest shows statistics of media worldwide, 100% increase in the number of USB flash drives user. SanDisk is the number 60 of the 100 fastest growing companies in FORTUNE.
USB flash drives are a relatively dense form of storage, even the cheapest and smallest flash memory chips, data disks to save tens of dollars. Most flash memory chip can today that new dataCD. Top of the line of flash drives more data, maybe even a DVD. Compact Flash storage available on the market before you get to 64 GB of memory PRAM. The devices most common sizes of 1 GB USB flash memory industry reports show a recent increase for the first time in over a year for these USB storage devices with 1 GB because of its popularity. The flash market experienced price declines. This is an indication that the profit margins of Memory Productsmay see more positive gains during the quarter.
can read and write your own operating system and USB flash drives without additional drivers. export rather than fixing the technical details of the basic equipment Composite USB flash drive, USB flash memory, a single unit structured logic blocks for the host operating system. The operating system is independent of the type of file system or block addressing scheme it wants.
Most USB flash drives do not usewrite protection mechanism. This switch actuator unit located in the mainframe data would change or a. Write-protect a system of writing would be appropriate for the repair of viruses infecting the host without the USB flash drive itself contaminated.
USB flash drives are more tolerant to mechanical abuse, but statistics show failure rate eprovided.com USB flash drive to 300% every year due to problems of quality control,misuse and a growing number of devices manufactured on the market shortly.
According to the expert Bruce Cullen, president of Data Recovery Services eProvided.com "Like other storage devices USB flash drives are mechanical and margins of mechanical threshold, and the problems faced by potential fragmentation issues. This fragmentation occurs when documents are created and then saved or deleted, and if the new files available onadjacent room. The data in these files is broken and the cells placed at random on the disk, start the resulting files are fragmented. Issues related to fragmentation is not known to consumers so that consumers are not adequately flash disk defragmentation. "
Generally, the consumer expects to find a single level cell NAND flash drive is a standard one can accuse of 100,000 read / write cycles, usually a huge amount of writing, reading for mainstream users. Topics such as virusesThe attacks, damage caused by extreme heat and hot air, troubleshooting, downloads, etc, the life of the equipment or cause a malfunction of a sudden shortening in many cases.
However, the real problem of the huge INCREASE USB disk defects in workmanship and quality control issues, defective flashes are poorly constructed compared to the contract specifications for the price control pulses with the parameters of a similar quality.
"I expect a dramatic increase in problems with USBflash drives, pushing a large number of companies producing fungi and flash storage today, "said Bruce Cullen are." Most manufacturers of USB flash memory in Taiwan, Singapore and China are due to price competition, these other companies by the quality, and because of that competition on price or quality of production and sale of flash memory circuits, capacitors and crystals low grade, resulting in a massive increase in the USBThe rate of failure and reliability problems. And 'the creation of themes, such as flash memory technology, "he added.
