In my own speed tests, the ProGrade Digital CFexpress Type A reader consistently outperformed the Sony MRW-G2. I often saw speeds in excess of 820MB/s for read speeds, which is remarkable given that the Sony card I used for testing only claimed a max of 800MB/s. Repeated tests made it clear to me that the ProGrade Digital reader is much faster. This is an excellent result considering that it is quite a lot cheaper. Conclusion The cards that perform best as hard drives hooked up to the computer are the Sony cards. They’ll offload images and video faster than the others. Around the same size and shape as a computer mouse, Sandisk’s Extreme Pro CFexpress card reader is a nicely designed piece of kit. The spring-loaded memory card slot has a pleasing action too, with a gentle push of the memory card ejecting it from the reader. The Lexar Professional Multi-Card 3-in-1 USB 3.1 reader is compact, sleek and looks pretty good too. It offers slots for CF, SD and micro SD, which covers the most popular memory card types.
In conducting the tests for the cards hooked up to a computer, we saw some very strange results, eventually figuring out that major differences would be introduced not only by using different card readers, but also even which port we chose to hook it up to on the computer, and also what sort of cord was used. These results retested, standardized on a Sonnet dual CFexpress card reader using a Thunderbolt 3 port and cord. The reader uses a 10 Gb/s USB 3.2 Gen 2 Type-C interface to provide fast transfer speeds of up to 1.25 GB/s, making it perfect for offloading large files, including high-res raw images, as well as 8K, 4K, Full HD, and 3D video. The reader is bus-powered, meaning that it doesn’t require an external power supply, making it easy to use on the go. With the latest laptops like the MacBook Pro ditching every port other than Thunderbolt/USB Type-C, it isn’t just your memory card that you may be struggling to connect.If you want the most number of shots in 30 seconds, you’ll have the Angelbird 660GB XT. But it’s best by only 1 picture out of 337, and it has an odd behavior of causing camera startup to take 4 more seconds than any other card. This will be a deal-breaker for some. As with the SD card format, there are several different types of CFexpress memory cards. CFexpress Type-B which is the most common for mainstream cameras.
You have dealt with many items and majority might have even failed. What we are bringing you now is one item that has been upgraded from its first make. This is a high grade professional item that has been made for photographers so that they never miss an action when they are taking their pictures and even videos. It is a plug and play item that does not need installation. Sony MRW-E90/BC2 XQD USB 3.0 Reader Price mattered to start, of course, but when you figure out that the performance on these cards is pretty consistently good, price takes on even greater importance as a differentiator. Here’s the breakdown of prices as of mid-September 2020 at B&H… In summary, the Exascend CFexpress Type A / SD Express Card Reader is a versatile and high-performance card reader that is designed to meet the needs of professionals who require fast and efficient data transfer. The reader’s dual-slot design, USB-C 3.2 Gen 2 interface, and rugged aluminum casing make it an essential tool for those working in demanding professional photography environments. The CFexpress standard, as interpreted by camera manufacturers, is still being established in implementation, so we can expect issues to crop up as new cameras are introduced and firmware needs to be adapted. There is no amount of testing that would solve the issue of a third party camera maker launching a camera with a slightly different protocol interpretation a year later, so all manufacturers are likely as vulnerable to this problem as all the others. It may be a fairly cheap card reader, but the ImageMate Pro feels like a quality product, as it’s well built and weighty enough to sit securely on a desk. And this is where it belongs, as at 122 x 58 x 17mm, it’s big by card reader standards.
The ProGrade Digital CFexpress Type A & UHS-II SDXC Dual-Slot USB 3.2 Gen 2 Card Reader is an affordable and high-speed memory card reader that is designed to work with both CFexpress Type A and UHS-II SDXC memory cards. With a maximum data transfer rate of up to 1.25 GB/s or 1250 MB/s, this card reader takes advantage of the 10 Gb/s USB 3.2 Gen 2 bus, which is even faster than the maximum speed of CFexpress Type A memory cards. When looking at online forum discussions for Canon EOS R5 performance, we noticed that several people seemed to think that the R5 had a terribly long initial startup time, making it inconvenient for action and wildlife photographers. Many of us other R5 owners were puzzled by this, as the spooling-up time seemed to be impressively short.
If you want the best price per GB, you’ll have the Delkin Power 512GB, which is also one of the top 5 in performance. The larger versions of these cards are even cheaper per GB; less than half the average price per GB of the other cards.Delkin’s CFexpress card reader is one of the best mid-range options and uses USB 3.2 Gen 2 Type C technology for fast data transfers. Boasting read/write speeds of 800MB/s and 700MB/s respectively, ProGrade's Cobalt CFexpress Type A offering matches its Sony 160GB counterpart for speed, yet it'll cost you around 10% less. That's a handy saving if you're in the US where ProGrade cards are readily available, but in other territories a Sony card might still be your only available option for CFexpress Type A. We tested using repeated real-world transfers of a large folder of image files (multiple small files will always take longer to copy/paste than a single video of the same total file size), as well as a single large 4K video file, to determine the maximum possible real-world sustained transfer speeds you're likely to achieve. Finally, to test theoretical maximum possible transfer speeds of the card, we used CrystalDiskMark's storage benchmarking software, specifically the sequential read/write setting. Other features include an LED light to show when transfers are active and compatibility with Windows and iOS.
On the outside there isn't much to get excited about with CFexpress, as CFexpress card closely resemble XQD cards, but it's this very compatibility that's a key CFexpress attraction. If you've not encountered an XQD - and by extension, CFexpress - card before, imagine a blend between a traditional CompactFlash card and an SD card and you won't be far off. It should be said that each of these cards has a different shooting rhythm style. The Sony 512 has a pleasing, consistent rhythm to the shots, shooting roughly equal amounts on and off after filling the buffer. The Lexar is a big more syncopated, perhaps less predictable. The Angelbird and ProGrade cards create more tension, with a spattery non-pattern. You never really know in which tenth of a second the shutter will start up again, or for how long. If you’ve recently invested in a camera with an XQD card slot, or XQD and SD cards slots, the Sony MRW-E90 XQD/SD Card Reader could be a good addition to your kit.Of interest here is the fact that Sandisk’s smaller card sizes – which sport very similar performance metrics on the label – perform terribly relative to the 512 GB card. Unfortunately, this seems to be the norm. Sony’s smaller sizes also perform poorly in the other tests relative to the 512 GB, although they are keeping up with their bigger sibling in this test of initial speed capacity. Heat
