The creators of the brand ProGrade not sit back. They promised to invest in CFexpress card technology, и вот результат – самая емкостная карта памяти доступна на рынке. The company does not forget about demanding users SD card.
Only recently, the issue was whether that XQD Memory Card will be superseded standard CFexpress. This future has already come, with the introduction of the world's first CFexpress memory card from ProGrade, whose capacity is up to 1 TB.

At first glance, the card CFexpress volume 1 TB may seem too capacitive, and having too much speed (record 1000 MB / sec, and reading 1400 MB / sec), but surely they can find a buyer. Of course, primarily interested in their professional photographers and cameramen to shoot the film. Over time, they become interested and lovers, since the resolution SLR cameras increases from year to year.
What is CFexpress?
CFexpress memory is essentially a successor XQD technologies. It uses the same chassis, ie more than the SD, but less than CF cards. Принимая во внимание объем и целевое назначение – 29,6 x 38,5 x 3,8 мм – это оптимальные размеры на сегодняшний день.
The size 1 TB, by far the highest, but we know that the option is expected in the future 2 TB. Without doubt volume model 512 GB i 1 TB will find their supporters.
CFexpress as XQD uses PCIe data bus, but has twice the number of channels (in the current version, This two channel). Besides, NVMe interface has been applied, which users of small solid state drives know well. These features allow data transfer rates of more than 1 GB / sec.
Effective SDXC memory, compatible with the V90 class
ProGrade company does not focus only on the memory CFexpress. She remembers the huge market SD memory cards, which is used in most consumer digital camera models. AND, probably, many more years will be used.
To meet the requirements of video recording in the resolution 4 or even 6K, SD Memory Card should be fast. ProGrade SDXC UHS-II V90 media available in capacities 64, 128 and 256 GB equipped with UHS-II bus, so that regardless of which version is able to record data at a maximum speed 200 MB / s, and read at a speed 250 MB / s. This allows you to match the class V90, which incidentally has a lower rate, ie at the level of 90 MB / s.
For SDXC memory card 64 GB will need to put up 100 dollars. It is not enough, but justified by the guaranteed outstanding performance. CFexpress media prices not yet known, but not likely to be small.
