Toshiba Develops Faster SD Cards

by Reads (21,467)

Toshiba America Electronic Components (TAEC) has just announced a family of High Speed SD Memory Cards that are up to five times faster than its standard SD memory cards.

The new High Speed SD Cards are initially available in densities of 128 MB and 256 MB, and are designated SD-F1284B1 and SD-F2564B1. They capable of achieving a maximum write speed of 10 MB/second and a sustained write speed of 5 MB/second.

Toshiba’s High Speed SD Memory Cards are based on Single Level Cell (SLC) NAND Flash technology, which stores one bit per cell, and utilize an optimized controller combined with large block NAND technology to achieve high data transfer rates.

Toshiba’s standard SD Memory Cards use Multi-Level Cell (MLC) NAND Flash, which allows each memory cell to store two bits of information. This reduces cost but also slows performance.

“Toshiba developed this new line of High Speed SD Cards with faster write speeds to meet the needs of higher performance applications such as digital video, and faster downloading of digital content such as music and motion pictures,” said Brian Kumagai, business development manager for NAND Flash memory at TAEC.

Samples of Toshiba’s 128 MB and 256 MB High Speed SD Cards are available now, priced at $70 and $110, respectively. The cards should be widely available in the near future. A 512MB High Speed SD Memory Card is expected from TAEC later this quarter.
