Several weeks ago, Lexar sent us their biggest and brightest 2TB Lexar Professional Gold CFExpress B Card and, well, it has found a permanent home in my Canon EOS R5 mirrorless digital full frame.  That wasn’t an easy feat considering I had relied solely on the ProGrade Cobalt 650GB card since its release 2 1/2 years ago, but this Lexar …

CFExpress Type B cards have become a main stream item and will be here for some time.  We don’t feel the same with respect to CFExpress Type A as it is supported by few media devices in comparison and can’t come close to capacity or speed of CFExpress Type B.  Don’t get me wrong. CFExpress Type B has had its …

CF Express Type-A memory cards are a particularly niche product restricted for the most part to those newer Sony camera lovers; Sony A7S III, A1 and A7 IV.  It was that mid-choice between XQD and CFExpress Type-B but then XQD saw firmware upgrades enabling CFExpress Type B which left Type-A on its own.  Our first showing of Type-A cards saw …

Lexar has recently released their Professional Diamond Series CFExpress Type B Memory Card and they believe this card is the ‘worlds fastest’ CFExpress card to date. Specifications list speeds of 1900MB/s read, 1700MB/s write and 1600MB/s sustained write and, if these numbers pan out, this would be an industry leading storage device.  As much as we appreciate these numbers, we …

One of the biggest advances at the forefront of digital technology in the past few years has to do with data storage and the introduction of CFExpress cards.  As an avid photographer and digital enthusiast, myself… I wonder what took so long and… in fact, I wonder why the digital industry has lagged so far behind when we consider the …

I get asked quite often what I prefer with respect to storage cards in my camera equipment.  I try to stay away from exact brands and move the conversation into what I believe are necessary characteristics of the cards that I will put in my digital equipment.  Three things stand out.   I want storage that has high sustained write speeds …

To say that CFExpress Type B cards haven’t redefined digital media in the past two years would be an understatement.  Many enjoy their advantages in moving large photo and video files from the card to PC for work in a fraction of the time that it used to take, but more importantly, its what CFExpress B cards do inside the …

Without a doubt, the toughest lesson learned on release of the Canon EOS R5 Mirrorless camera was that of storage and this relatively new thing called sustained write performance.  Countless people purchased these cameras, along with first generation CFExpress Type B cards that had not been approved by Canon.  They quickly learned that features that should be available within their …

The popularity of CFExpress Type B cards has been overwhelming over the past year and we are certain that it will continue to grow as newer digital equipment is released with this type of storage in mind.  It moves us from under 100MB/s data transfer speed for most up to over 5x that with CFExpress highs of 1700MB/s.  Don’t get …

Type B CFExpress cards have gained massive popularity as of late  but what about CFExpress Type A.  Has it been forgotten?  The unfortunate reality of CFExpress Type A cards is that they are a very niche product limited to very few Sony cameras; the Sony a7S III, FX3 and Fx6 specifically. If it’s a professional DSLR that has CFExpress storage, …
