CHIPMAKER Toshiba has announced its Exceria Pro series of compact flash memory cards sporting read and write bandwidths of 160MB/s and 150MB/s, respectively.

Toshiba, known more for its NAND flash memory than its consumer compact flash memory cards, claims have the world's highest bandwidth compact flash card with its Exceria Pro models. The firm announced 16GB, 32GB and 64GB cards, with the 32GB and 64GB models sporting 160MB/s read and 150MB/s write bandwidth.

Toshiba said its Exceria Pro cards comply with the Video Performance Guarantee Profile 2, which should provide some indication as to where the firm expects these cards to be used. The firm said that its Exceria Pro cards use its own NAND flash chips and its own firmware.

While Toshiba's 32GB and 64GB Exceria Pro cards offer breathtaking performance for compact flash cards, the 16GB card has a slightly more modest write bandwidth of 95MB/s, though read bandwidth remains at 160MB/s.

Toshiba said it expects the cards to be used in devices that record video at 4K resolution. However the firm is likely to see interest for its latest cards from those that use digital SLR cameras where compact flash memory is still the primary storage medium, and higher write bandwidths will allow longer continuous image capture before the camera's buffer is filled.

Toshiba said its Exceria Pro range of compact flash memory cards will go in sale in Japan on 27 April. While the firm said it will offer the cards in Europe and North America, it didn't say when. µ
