The brand new CFexpress 4.0 specification guarantees considerably sooner switch speeds than the playing cards recently in the marketplace and whilst no digicam can make the most of it at this time, your pc can, which makes a robust case for consolidating your garage {hardware} right into a unmarried media.

Introduced on the finish of August, CFexpress 4.0 remains to be just a little of some distance out for many reminiscence card producers. No longer ProGrade Virtual, alternatively, who introduced a brand new 1.3TB card and card reader only some days later.

PetaPixel were given its fingers in this very new {hardware} and the preliminary assessments are proving extraordinarily spectacular. The brand new reminiscence card was once in a position to mainly triple the examined learn speeds of our best-performing last-generation CFexpress playing cards and it was once just about 4 instances sooner in terms of write speeds:

In truth, those speeds are so just right that they’d blow any non-Thunderbolt SSD out of the water and are the nearest we’ve ever observed USB come to the efficiency of the OWC Envoy Professional FX and Lacie Rugged SSD that we examined in our very best SSD information.

This top efficiency is such that it lets in photographers and filmmakers a brand new choice: ditch moveable, standalone SSDs and simply use CFexpress and a reader. PetaPixel‘s Jordan Drake already does this with less-intensive video information, you’ll be able to use them with the brand new iPhone 15 Professional (it treats the playing cards similar to an SSD), and the speeds proven right here illustrate that CFexpress 4.0 is rapid sufficient to function as a devoted power for even 8K workflows. With earlier CFexpress, there simply was once now not sufficient bandwidth for 8K ProRes 422 HQ information. Now? No drawback.

However the excellent news doesn’t forestall there: editors gained’t even wish to purchase a brand new CFexpress 4.0 card to make the most of this selection.

The true benefit for CFexpress 4.0 and related readers is the bandwidth of the USB 4.0 interface they’re supported through. ProGrade’s new $100 reader is started working with its new playing cards, however the wonderful thing about CFexpress is that it’s backward suitable, which means older CFexpress 2.0 playing cards can get a efficiency spice up in the event that they’re plugged into a brand new reader.

For instance, underneath are the trying out numbers from a brand new Silver version Lexar 512GB CFexpress card — the similar style it introduced in August — as processed thru Lexar’s latest-generation USB 3.2 card reader:

Those are very, excellent numbers through outdated metrics. So just right, it might be poised to unseat the Sony TOUGH CFexpress Kind B card that has been PetaPixel‘s advice for the final 12 months.

However this card isn’t even appearing us its very best as a result of that USB 3.2 reader doesn’t have the bandwidth to permit the cardboard to in reality act on its true doable. Putting the Lexar card in ProGrade’s new reader presentations us what it’s in fact in a position to:

That isn’t a small building up: that represents about 300 MB/s sooner write speeds and about 700 MB/s sooner learn speeds simply by the use of a next-generation reader. Clearly, because of this PetaPixel must replace its whole CFexpress reminiscence card take a look at and put in combination new numbers according to what’s imaginable due to USB 4.0, so sit up for that within the close to long term.

The primary takeaway here’s that USB 4.0 CFexpress card readers are in a position to letting present playing cards succeed in new heights. If photographers and filmmakers have CFexpress playing cards already, getting a $100 reader will supply them get admission to to speeds that outpace all different USB 3.2 moveable SSDs (USB 3.2 2×2 was once now not examined as a result of it’s so uncommon). Simply be sure that the host pc is equipped to strengthen USB 4.0. Whilst now not each and every pc has it, it’s way more commonplace than USB 3.2 2×2: Apple has been transport it in its units for a while now.

Doing this may permit photographers and filmmakers to scale back the entire funding in reminiscence and make allowance playing cards to accomplish double accountability — report within the box and function a operating power within the administrative center. That’s what PetaPixel can handiest describe as a win.
