Companies in particular are at risk when sensitive data are stored on unsecured USB flash drives by employees who use the devices to transport data outside the office. The consequences of losing drives loaded with such information can be significant, including the loss of customer data, financial information, business plans and other ...
A flash drive (also thumb drive, memory stick, and pen drive/pendrive) [1] [note 1] is a data storage device that includes flash memory with an integrated USB interface. A typical USB drive is removable, rewritable, and smaller than an optical disc, and usually weighs less than 30 g (1 oz).
High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small 3-inch (7.6 cm) nickel plate. Up to 196,000 8.5×11 in (22×28 cm) pages of information can be stored onto the plate using a focused ion beam.
Network Direct Attached Storage (NDAS) is a proprietary storage area network system, originally marketed by the company Ximeta, for connecting external digital storage devices such as hard-disks, flash memory and tape drives via the Ethernet family of computer networks.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
The programming is permanent, and further changes require the replacement of the device. Data is stored by physically altering (burning) storage sites in the device. An EPROM is an erasable ROM that can be changed more than once. However, writing new data to an EPROM requires a special programmer circuit.

A direct-access storage device (DASD) (pronounced / ˈ d æ z d iː /) is a secondary storage device in which "each physical record has a discrete location and a unique address". The term was coined by IBM to describe devices that allowed random access to data, the main examples being drum memory and hard disk drives . [ 1 ]
