mikroSD

mikroSD is a family of flash memory cards based on the Secure Digital (SD) standard that uses a small form factor. Introduced by SanDisk and the SD Association in 2005, mikroSD cards are widely used in smartphones, tablets, cameras, and other portable electronics. The cards measure 15 mm by 11 mm by 1 mm and can be used in devices with a mikroSD slot or in full-size SD slots via an adapter.

Capacity and variants: The mikroSD family includes mikroSD, mikroSDHC (High Capacity), mikroSDXC (eXtended Capacity), and mikroSDUC (Ultra Capacity). The mikroSD base format supports small capacities, while the HC and XC variants increase capacity: mikroSDHC cards range from 4 GB to 32 GB, mikroSDXC from 32 GB to 2 TB. The mikroSDUC specification extends theoretical capacities up to 128 TB, though such cards are rare and not widely supported by devices yet.

Speed and compatibility: The mikroSD family uses speed class ratings to indicate performance: Class 2-10, UHS speed classes U1 and U3, and newer Video Speed Class ratings V30, V60, and V90. Real-world speeds depend on the card and the host device. mikroSD cards can be used in devices with mikroSD slots or via adapters to full-size SD; however, read/write performance may vary, and high-end cards are preferred for 4K video or rapid burst photography.

Usage and reliability: mikroSD is widespread in consumer electronics, including smartphones, tablets, action cameras, drones, and portable consoles. To maintain data integrity, format cards in the device they will be used, back up important data, and avoid abrupt removal. Buy from reputable brands and verify compatibility with the host device. While mikroSD is robust for everyday use, high-end applications or extreme conditions may require industrial-grade or built-in storage alternatives.
