The endurance of an SSD is typically listed on its datasheet in one of two forms: either n DW/D (n drive writes per day) or m TBW (maximum terabytes written), abbreviated TBW. [43] For example, a Samsung 970 EVO NVMe M.2 SSD (2018) with 1 TB of capacity has an endurance rating of 600 TBW. [44]

SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. [7] In 1991, SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000. [8]
SanDisk again announced pre-loaded cards in 2008, under the slotMusic name, this time not using any of the DRM capabilities of the SD card. [145] In 2011, SanDisk offered various collections of 1000 songs on a single slotMusic card for about $40, [ 146 ] now restricted to compatible devices and without the ability to copy the files.
Uses the SCSI command set including queuing. The electrical interface makes use of differential signaling, which enables high bus speeds and robustness under noisy conditions and reduced pin count (compared to parallel bus alternatives such as UHS-I). USB flash drive: Various USB 1.1/2.0/3.0/3.1 2000/2001 1 TB+ (not to scale)
Like MMCmobile, MMCmicro allows dual voltage, is backward compatible with MMC, and can be used in full-size MMC and SD slots with a mechanical adapter. MMCmicro cards have the high-speed and four-bit-bus features of the 4.x spec, but not the eight-bit bus, due to the absence of the extra pins. [10]
SanDisk Professional (previously G-Technology) is a brand of Western Digital that produces external storage products designed and marketed for the Macintosh, creative pro, photography and A/V markets. [1] Its USB, FireWire, eSATA, SAS, SCSI Thunderbolt, and Fibre Channel systems support all levels of audio/video production. [2]
CompactFlash IDE (ATA) emulation speed is usually specified in "x" ratings, e.g. 8x, 20x, 133x. This is the same system used for CD-ROMs and indicates the maximum transfer rate in the form of a multiplier based on the original audio CD data transfer rate, which is 150 kB/s.
