Applications that comply with U3 specifications are allowed to write files or registry information to the host computer, but they must remove this information when the flash drive is ejected. Customizations and settings are instead stored with the application on the flash drive. Microsoft and SanDisk created a successor called StartKey.
The SanDisk Cruzer Enterprise [1] was an encrypted USB flash drive. This secure USB drive imposed a mandatory access control on all files, storing them in a hardware-encrypted, password-protected partition. The Cruzer Enterprise is designed to protect information on company-issued USB flash drives.
Secure USB flash drives protect the data stored on them from access by unauthorized users. USB flash drive products have been on the market since 2000, and their use is increasing exponentially. [ 1 ] [ 2 ] As businesses have increased demand for these drives, manufacturers are producing faster devices with greater data storage capacities.
Until 2008, SanDisk manufactured a product called SD Plus, which was a SecureDigital card with a USB connector. [81] SanDisk introduced a digital rights management technology called FlashCP that they had purchased in 2005 to control the storage and usage of copyrighted materials on flash drives, primarily for use by students.
The other type of wear leveling is called static wear leveling which also uses a map to link the LBA to physical memory addresses. Static wear leveling works the same as dynamic wear leveling except the static blocks that do not change are periodically moved so that these low usage cells are able to be used by other data.
Write blocking, a subset of write protection, is a technique used in computer forensics in order to maintain the integrity of data storage devices. By preventing all write operations to the device, e.g. a hard drive , it can be ensured that the device remains unaltered by data recovery methods.
The position [i.e., setting] of the write protect switch is unknown to the internal circuitry of the card." [121] Some host devices do not support write protection, which is an optional feature of the SD specification, and drivers and devices that do obey a read-only indication may give the user a way to override it.

First SanDisk logo (1995–2007) Second SanDisk logo (2007–2024) SanDisk (originally Sundisk) was founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan. [5] In 1995, just before its initial public offering, SunDisk changed its name to SanDisk, to avoid confusion with Sun Microsystems, a prominent computer manufacturer at the time. [6]
