Up to now few months CFexpress Kind B playing cards developed from the super-expensive-but-fast choice for flagship our bodies to super-fast, almost-as-cheap-as-SD-UHS-II playing cards. And so they received quicker nonetheless. Clever, Delkin and Angelbird launched new playing cards and Mark II variations of older playing cards. Every launched a flagship line designed for extra dependable high-bandwidth video recording and an improved massive capability line that’s cheaper. Camnostic up to date its complete overview of CFexpress Kind B playing cards to check these new choices and others in opposition to a quickly rising library of legacy playing cards.
Of all of the playing cards examined over the past two years, the highest three performers have been all launched prior to now few months to the previous few days. Launched earlier this week, the Angelbird AV Professional XT Mark II 660 GB card (pictured left, within the center) proved the quickest in pushing nonetheless images onto the cardboard. The Mark I model is on the left, and the brand new 2 TB Professional card is on the precise. Subsequent in efficiency are the Clever 320 GB and the Delkin Black 512 GB, as quantity two and three respectively. The graph under exhibits velocity as blue outlined containers displaying velocity (greater is best).
However to place issues in perspective, the first-place Mark II model of the Angelbird AV Professional XT card’s velocity improve is barely 5 frames over 30 seconds quicker than the Mark I model of the identical card; now in seventh place.
The complete vary of manufacturers is proven under:
Extra attention-grabbing to most individuals are the developments on the different, cheaper finish of the graph. Delkin and Angelbird have been lowering the worth of their very massive capability playing cards. Whereas the Delkin card could sit within the decrease half of the velocity rankings, it’s nonetheless pushing 90 p.c as many images onto the cardboard per second as the highest performing card. And the cheaper Angelbird card competes with the perfect in velocity, but is barely a bit of dearer than the Delkin Energy card. They price roughly 1 / 4 the worth per gigabyte; as seen within the graph above with the strong orange columns (decrease is cheaper).
Camnostic up to date virtually the entire figures in its CFexpress complete overview, as new digicam firmware required new knowledge throughout all playing cards to do correct comparisons. Curiously, Canon made small modifications to how the R5 and R3 at this time deal with CFexpress playing cards versus the unique R5 firmware launched in July 2020. This meant that many charts needed to be up to date to mirror the relative efficiency with the newer firmware.
The typical value per gigabyte for CFexpress Kind B playing cards lowered from a bit over $1.20 again when the R5 launched the demand for the format to round $1.10 within the fall of 2021, and now in 2022 sits under $1.05. That is taken from knowledge collected periodically from main on-line retailer pricing for a similar playing cards over time. The picture at proper exhibits the overall downward shift for many playing cards, with just some exceptions.
In comparison with different codecs, the CFexpress Kind B card costs are getting higher quicker. Pricing for SD UHS-II playing cards has been stagnant over the previous two years. CFexpress Kind A, popularized with some main Sony physique releases, has solely just lately seen competitors come into the market. ProGrade and Delkin joined Sony in producing the playing cards, however the brand new opponents didn’t underprice Sony by a lot. And the CFexpress Kind A playing cards – each intrinsically slower and smaller capability – began off at about twice the worth per gigabyte as CFexpress Kind B playing cards.
Additionally new to the market is a do-it-yourself package offered by Sintech, which gives a CFexpress Kind B case into which a separately-sourced SSD drive (2230 nVME chips faraway from recreation consoles work properly) may be inserted. It requires the applying of specialised – additionally not included – electronics warmth paste, and may not be for these uncomfortable with the entrails of digital units. But it surely does present the most cost effective CFexpress Kind B choice. After sourcing components from Turkey, the US and China, we put collectively a 512 GB card that price us in all about $96.
The shocking factor was how briskly the cardboard is. Whereas on the decrease finish, it’s nonetheless quicker than ProGrade Gold playing cards and prices lower than one fifth the quantity per gigabyte.
Pictured at proper, the cardboard has been used for a number of weeks with out incident. It does seem to get hotter than different playing cards, and overheated an R5 capturing 8K about twice as quick as most different playing cards. The interior drive is a 512 GB Kioxia (previously Toshiba) chip taken out of a recreation console that was being upgraded.
The extra complete overview has extra conclusions, however for these on the lookout for suggestions, it’s onerous to not go together with one of many three least expensive choices. For these not prepared to go DIY, the Angelbird and Delkin massive capability playing cards (Angelbird AV Professional or Delkin’s Energy fashions in 2 terabyte capacities) are clear winners for bang for the buck, and each corporations have been among the many most proactive in each service and firmware growth. Video shooters with video-class budgets and 8K or 4K HQ wants would possibly take a look at the other finish of the graph. The highest three in velocity efficiency (Delkin Black, Clever 320 and Angelbird AV Professional XT Mark II) are priced equally and are among the many latest market entries.
