microSD (2005 – ) | Museum of Obsolete Media (original) (raw)
microSD (also called TransFlash) is a smaller variant of Secure Digital (SD), created by SanDisk and introduced in 2005.
SanDisk introduced microSD as current memory cards were too large for newer mobile phones.
Initially, microSD cards were available in capacities of 32, 64, and 128 MB, but the original microSD standard allowed for up to 2 GB of storage. microSDHC (introduced in 2007) allows for between 4 and 32 GB, and microSDXC (introduced in 2009) allows for up to 2 TB. As of 2019, the largest commonly available microSDXC cards are 1 TB.
microSD cards will work in devices that require SD or miniSD cards by use of an adaptor.
microSD has also been used as a format to distribute music, most notably in the form of gruvi and subsequently slotMusic by Sandisk, MQS by Astell&Kern, and also on generic microSD cards.
