The Linux kernel has supported USB mass-storage devices since version 2.3.47 [3] (2001, backported to kernel 2.2.18 [4]).This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling the ...
On April 5, 1999, Amir Ban, Dov Moran, and Oron Ogdan of M-Systems, an Israeli company, filed a patent application entitled "Architecture for a Universal Serial Bus-Based PC Flash Disk". [ 11 ] [ 3 ] The patent was subsequently granted on November 14, 2000, and these individuals have often been recognized as the inventors of the USB flash drive ...
Whereas NOR flash might address memory by page then word, NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial applications (such as hard disk emulation), which access only one bit at a time. Execute-in-place applications, on the other hand, require every bit in a word to be accessed simultaneously. This ...
A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
The first magnetic tape drive, the Univac Uniservo, recorded at the density of 128 bit/in on a half-inch magnetic tape, resulting in the areal density of 256 bit/in 2. [6] In 2015, IBM and Fujifilm claimed a new record for the magnetic tape areal density of 123 Gbit/in 2 , [ 7 ] while LTO-6 , the highest-density production tape shipping in 2015 ...
To set up a live USB system for commodity PC hardware, the following steps must be taken: A USB flash drive needs to be connected to the system, and be detected by it; One or more partitions may need to be created on the USB flash drive; The "bootable" flag must be set on the primary partition on the USB flash drive
For each file, exFAT uses two separate 64-bit fields in the directory: the valid data length (VDL), which indicates the real size of the file, and the physical data length. To provide improvement in the allocation of cluster storage for a new file, Microsoft incorporated a method to pre-allocate contiguous clusters and bypass the use of ...
Binary digits are found together in 128-bit collections. Modern GPU chips may operate data across a 256-bit memory bus (or possibly a 512-bit bus with HBM3 [3]). The Efficeon processor was Transmeta's second-generation 256-bit VLIW design which employed a software engine to convert code written for x86 processors to the native instruction set ...
