M2kortit

M2kortit, also known as M2 cards, are a type of memory card used primarily in digital cameras and other portable devices. They were developed by Panasonic and Toshiba in 1999 as a smaller, more compact alternative to the Secure Digital (SD) card. The name "M2" stands for "Micro2," reflecting its small size and the fact that it was designed to be a second-generation memory card.

M2kortit cards are physically smaller than SD cards, measuring 18.0 mm × 14.0 mm × 1.8 mm, making them suitable for compact devices where space is limited. Despite their small size, M2 cards offer storage capacities ranging from 32 MB to 1 GB. They use a 16-pin interface and support both asynchronous and synchronous data transfer modes, with speeds up to 4 MB/s.

One of the notable features of M2kortit cards is their compatibility with certain devices through the use of adapters. For instance, they can be used in devices that support SD cards by using an M2 to SD adapter. This adapter allows the M2 card to fit into an SD card slot, making it versatile for various applications.

Although M2kortit cards were once popular in certain digital cameras and other portable electronics, their usage has declined over time due to the widespread adoption of more advanced memory card formats like SDHC, SDXC, and microSD. These newer formats offer higher storage capacities and faster data transfer speeds, making them more suitable for modern devices.

In summary, M2kortit cards represent an early effort to create a compact and efficient memory card format. While they are less common today, they played a significant role in the evolution of digital storage technology.
