MEMORY MAKER Samsung launched a 64GB microSD card that it claims has 70MB/s read bandwidth.
Samsung introduced its Pro series of microSD memory cards that tops out at 64GB. The firm said the cards support the UHS-1 standard, and have read bandwidth of up to 70MB/s, putting them close to high-end compact flash memory cards in performance.
Samsung said its 64GB microSD Pro card uses 20nm class NAND flash and the firm is pitching it to high-end smartphones. Samsung said the card can play back HD 1080p resolution videos, and while it didn't spend too much time talking up the maximum 104MB/s write bandwidth, it could be a tempting proposition for use in high-end digital SLR cameras with the addition of an adaptor.
According to Samsung, its microSD Pro cards are waterproof and shielded against magnetic fields and X-rays.
Development in microSD card technology has been driven by smartphones, many of which can now make use of high read and write bandwidth thanks to high resolution cameras and the ability to play back high-definition content.
Samsung said its Pro range of microSD cards will be available in October, but didn't say what capacities other than 64GB will be available, nor did it quote pricing. µ
