Because they are solid state - there are no moving parts - flash drives usually last longer and the data stored on them is safer. They can transfer data much more quickly than these older technologies. BenefitsĮquipped with a large amount of memory, the pen drive is often considered to be an improvement on both the older floppy drive disks and the more modern compact disks. The age of the drive and how it's being used - such as for writing and erasing small files - also affects the transfer speed. Manufacturers usually list the speed in megabytes per second (MB/s). Generally, a pen drive's advertised speed is the reading speed because it is faster than the speed at which data can be written to it. The actual transfer speed depends upon several factors, such as the computer's speed at reading and writing to the device.
Using blocks rather than allowing random access allows the drive to store more information and be made at a lower cost.
This technology works by storing data in blocks rather than randomly as such, it doesn't work in the same way that a computer's main memory systems - read-only memory (ROM) and random-access memory (RAM) - do. Technicians classify pen drives as NOT AND, also called NAND, gate-style data storage devices.
