which type of storage technology is used in pen drives
USB flash drive A USB flash drive, also variously known as a thumb drive, pen drive, jump drive, disk key, disk on key, flash-drive, memory stick or USB memory,[a] is a data storage device that includes flash memory with an integrated USB interface. It is typically removable, rewritable and much smaller than an optical disc. Most weigh less than an ounce (approx. 30g).[1] Since first appearing on the market in late 2000, as with virtually all other computer memory devices, storage capacities have risen while prices have dropped. As of March 2016[update], flash drives with anywhere from 8 to 256Â GB are frequently sold; less frequent are 512 GB and 1 TB units.[2][3] Storage capacities as large as 2 TB are planned, with steady improvements in size and price per capacity expected.[4] Some allow up to 100,000 write/erase cycles, depending on the exact type of memory chip used, and are thought to last between 10 and 100 years under normal circumstances. shelf storage time.[5][6][7]
Digital cinematography Digital cinematography has mostly shifted towards "tapeless" or "file-based" workflows. This trend has accelerated with increased capacity and reduced cost of non-linear storage solutions such as hard disk drives, optical discs, and solid-state memory. With tapeless workflows digital video is recorded as digital files onto random-access media like optical discs, hard disk drives or flash memory-based digital "magazines". These files can be easily copied to another storage device, typically to a large RAID (array of computer disks) connected to an editing system. Once data is copied from the on-set media to the storage array, they are erased and returned to the set for more shooting.
