Last year, Wise issued a batch of CFexpress Type-A memory cards with big promises but no certification to back them up. The corporation has done the right thing, and its new cards are speedier and have more capacity possibilities.

The company’s first CFexpress Type A cards were available in 160GB and 512GB capacities, with varying projected levels of performance. While both had peak read and write rates of 820 MB/s and 730 MB/s, the lesser capacity card was able to sustain higher speeds of 650 MB/s. The bigger capacity card only guaranteed to support 200 MB/s.

However, the Compact Flash Association did not verify the promised sustained speeds, hence neither card was VPG-certified. Lacking certification did not appear to be a problem as long as the cards delivered on what Wise promised, but in actuality, the opposite is true. Sony requires VPG certification to unlock the highest-end video recording capabilities on some of its cameras, which means that without it, certain frame rates will be limited, even if the card is theoretically capable of handling the data.

Since this became more widely known, several memory card manufacturers who were avoiding VPG certification have fallen in line, and Wise is the latest to do so. Its Type A cards are now back in stock, with not only greater capacity options, but also consistent speeds across the board and VPG certification.

“Now that we are VPG certified and fully compliant with industry standards, Alpha users can make a choice,” explains Wise Senior Product Manager Frank Wang. “It’s about authenticity and dependability, correct? There are choices now.”

All three Wise CFexpress 4.0 Type A Mk-II versions maximize the performance of Alpha cameras by supporting all video codecs, including slow-and-quick modes in HD and 4K in XAVC S-I format.

Wise no longer makes maximum sustained write speed promises, instead stating the definition of VPG400: write speed will never drop below 400 MB/s. It claims that its new cards, which come in 256GB, 512GB, and 1TB capacities, have peak read speeds of 1,865 MB/s and peak write speeds of 1,750 MB/s.

The Wise CFexpress 4.0 Type A Mk-II cards will be available in early June, priced at $219.99, $359.99, and $549.99, respectively. Not only are these cards legitimate and significantly faster, but they are also less expensive per gigabyte than the first generation cards.
