Crucial microSD (Secure Digital™) Card

The microSD card's tiny size, about 38 percent of the (surface area) size of a miniSD card and a mere 21 percent of the (surface area) size of a regular SD card, is designed for use in cellular phones with memory-hungry multimedia features such as music players and built-in digital cameras.

The microSD card is for use in devices equipped with microSD slots. The card can utilize the provided adapter that converts the microSD card into a regular-sized SD card, allowing the microSD to be used with other regular SD-compatible devices, such as digital cameras, MP3 players, and handheld computers. The adapter is also convenient for using a microSD card in card readers that accept SD cards but not microSD cards.

At its release, the microSD card is the smallest memory card with worldwide availability, measuring 0.4331 inches wide, 0.5906 inches high, and 0.03937 inches thick (11 mm by 15 mm by 1 mm) and weighing 0.4 grams.

What is flash technology? Flash cards are solid-state devices designed with NAND flash technology, a non-volatile storage solution that does not lose its information when power is removed from the card. The cards contain no moving parts and are extremely rugged, providing much greater data protection than conventional magnetic disk drives.

1 gigabyte (GB) = 1 billion bytes. Total accessible capacity varies depending on operating environment
