MEMORY MAKER Toshiba has announced four Secure Digital cards that offer up to 260MBps read and 240MBps write bandwidth for 4K video recorders.
Toshiba's range of high-end Exceria Secure Digital cards will receive a performance boost that should take it to the top of the pile for bandwidth performance. The firm's Exceria Pro cards come in 16GB and 32GB capacities and will offer read and write bandwidth of 260MBps and 240MBps, respectively.
The memory maker will also release two Exceria cards with 32GB and 64GB capacities that have 260MBps read bandwidth but lower 120MBps write bandwidth. The firm's four new Exceria cards will support the UHS-II format.
According to Toshiba, the impressive bandwidth in the Exceria Pro cards is due to a new controller that supports the UHS-II standard. The firm said that as cameras increase in resolution the need for higher bandwidth cards is growing, and it is good to see the vital write bandwidth almost gaining parity with read bandwidth.
Toshiba has been pushing its NAND flash memory production for solid-state drives in PCs, laptops and tablets along with removable media such as Secure Digital cards. The firm said it will continue to ramp up memory card production that meets UHS-II specifications if it sees market demand.
Toshiba said its Exceria Pro cards will be available on shelves in October, while its Exceria cards will be available in November, with all four Secure Digital cards having open pricing highlighting the volatility of removable flash memory pricing. µ
