In general, USB flash memory devices are small, lightweight, convenient, low cost, rewriteable and removable USB flash drive memory type NAND memory interface data with integrated USB. There are several advantages over other portable storage devices, especially conservative media such as floppy disks, USB drives are 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 statistics show global average rise of 100% in the number of USB flash drives user.
SanDisk ranks No. 60 of 100 fastest growing companies in the Fortune list.
USB flash drives are a relatively dense form of storage, even the cheapest and smallest flash memory chips, the data is to save dozens of floppy disks worth. Most flash memory chip can today, as more dataa CD. Top of the line flash drive can also more data on a DVD. Compact Flash storage available on the market soon and come from 64 GB memory PRAM. The most common USB flash memory devices are the size of 1 GB on the latest industrial relations show an increase for the first time in over a year for these 1GB USB storage devices because of their popularity. The flash market had only recently experienced price declines. This is an indicator that the profit margins on memory productscan see much more positive earnings in the quarter.
can read and write, most modern operating systems and USB flash drives without additional drivers.
export, rather than expose the composite technical details of USB flash memory devices basic USB flash drives, a simple block-structured group logical host operating system. The operating system is independent of the type of file system or block addressing scheme it wants.
Most USB flash drives are not using aWrite protection mechanism. This switch on the body of the actuator that would keep the data on the host computer to write or edit a. Both write-protection device for repairing virus-contaminated USB host to infect appropriate one without the flash drive itself.
USB flash drives are more tolerant of abuse of mechanical drives, but the failure rate USB flash drive under eprovided.com statistics show 300% annual increaseproblems of quality control, improper use and an increasing number of devices manufactured on the market shortly.
According to the expert Bruce Cullen, president of data recovery services eProvided.com “Similar to other memory devices, USB flash drive mechanics and mechanical memory margin threshold, and tackle the problems of fragmentation potential. This fragmentation occurs when documents are created and then saved or deleted and if the new fileslarger than the adjacent room. The data in these files is broken and the cells placed at random on the disk, open the resulting files are fragmented. The issues of fragmentation is not known to consumers so that consumers are not defragging their flash drives correctly. “
It is generally expected to find a consumer that a single standard NAND flash drive cellular level can recognize a 100,000 read / write cycles, usually an immense amount ofReading and writing for ordinary users. Issues such as virus attacks, damage caused by heat and cold, failure, shock, etc., cases, power can shorten the life of the disc or cause a sudden failure in many.
