The 3rd-Generation CFast 2.0 Cards that ProGrade has to Offer Are the Company’s Quickest Ever

Even though the usage of the CFast file format has been on the decline in recent years, the CFast file format is still required for use in some cameras, such as Blackmagic’s Pocket Cinema Camera. In light of this, ProGrade Digital has launched its third-generation CFast cards, which are the company’s fastest cards to date.

Even though the CFast standard allows for a data transmission speed of up to 600 MB/s, no vendor has yet been successful in reaching that limit. On the other hand, CFexpress may get significantly, significantly faster, and contemporary GPUs already outpace the quickest that CFast has ever been able to attain.

The difference in interfaces between CFast and CFexpress is what prevents CFast from reaching those greater speeds. CFast utilizes SATA, whereas CFexpress uses PCIe. Since the exact speed maximum of SATA is not theoretical, it is not actually possible to go faster than 600 MB/s on the format. SATA is not able to grow to meet the demands of 6K and 8K cameras, which is one reason why the PCIe format CFexpress has grown so popular in recent years.

There are still a few cameras on the market that use the more archaic CFast format, but the vast majority of cameras that have been introduced in the past few years have transitioned to either the CFexpress or SSD storage technology. As a result, ProGrade is continuing to manufacture the format.

Memory cards from the CFast 2.0 Cobalt series manufactured by ProGrade Digital are of the third generation and come in sizes of 320GB and 650GB. These cards provide read rates of up to 550MB/s, burst-to-write speeds of up to 520MB/s, and sustained write speeds of up to 470MB/s.

That performance is just somewhat higher than what the business was able to wring out of its earlier Cobalt series cards, which claimed read rates of up to 525 MB/s and write speeds of up to 445 MB/s.

Note that these cards only have a rating of VPG 130, which indicates that the cards have only been approved to sustain transfer speeds of up to 130 MB/s while in operation. This rating is significantly slower than the VPG 400 rating that is increasingly becoming standard on CFexpress cards.

The latest CFast cards come equipped with error correction technology that can identify and fix data write and transfer problems. These controllers are optimized for use in professional-grade cameras and are built exclusively for use in such cameras. In addition, according to ProGrade, the cards include something called “wear-leveling,” which safeguards the integrity of the data and enables them to last for a far longer period of time.

In addition to being resistant to x-rays and shocks, the Cobalt cards can function in temperatures ranging from 0 to 70 degrees Celsius (0 to 70 degrees Celcius). In order to facilitate speedy compatibility testing and after-sales assistance, each card has a laser-etched serial number, and the product comes with a guarantee that is good for three years.

Late in the month of December, consumers will be able to acquire the brand new third-generation CFast 2.0 Cobalt series memory cards for a price of $330 for a 320GB card and $600 for a 650GB capacity card.
