SanDisk Extreme PRO CFexpress Card Reader USB-C USB 3.1 Gen2 compatible with CFexpress Type B format

Product Information

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.

The Sony MRW-G1 CFexpress Type B/XQD Memory Card Reader also comes with both USB Type-C to Type-C and USB Type-C to Type-A cables, making it compatible with a wide range of devices. This is particularly useful for those who work with a variety of different computers and devices and need a card reader that can work with all of them. USB 3.1 Gen 2 is twice as fast than Gen 1, but few readers use it, and even fewer memory cards are fast enough to exploit Gen 2.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.

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. The market for CFexpress Type A card readers is still relatively new, and the options are somewhat limited. However, there are several models available that offer impressive transfer speeds and convenient features to help streamline your workflow. Some readers use a USB cable that’s hard-wired to the reader body, which can be problematic if the cable ever gets damaged.

One of the standout features of this card reader is its anodized aluminum construction, which makes it sturdy and durable, perfect for use on-the-go. Additionally, the reader has a rubber end cover that protects the CFexpress Type A slot when not in use. The reader also has multiple heat sinks for increased cooling, ensuring that it stays cool even when transferring large files. This card reader sports the classic combo of SD and CompactFlash slots, both being the fastest of their type - UHS-II, and UDMA 7. You can use both simultaneously, and the case’s design means a card of each type can be stored inside the reader, protected by a hinged rubber door that closes around them. On the one hand these figures are hugely impressive results that eclipse any other memory card we've ever tested. However, aside from the 1678MB/s theoretical read speed score we achieved, which comes very close to the 1700MB/s claimed by Sandisk, in every other respect our CFexpress card didn't reach its claimed maximum speeds. The problems noted above can be solved with the use of either the Delkin or the Angelbird card readers, which each work fine with all 10 cards tested. Methodology

The card that clears the buffer the fastest is the SanDisk Extreme Pro 512GB, clearing it more than half a second faster than the other cards of its capacity. [Note the late entry of the Lexar Professional 512 GB card after this article was written upset this record, but both are fantastic at clearing cache.]

Here are our top recommended & fastest CFexpress Type B card readers and CFexpress Type A card readers in 2023: CFexpress Type B Card Readers: Relative to one another, the cards in the same class as one another showed only about 10 percent variance in performance. There certainly is shown a different set of classes, though, when looking at the 128 GB and 256 GB cards versus the higher capacity models. Those smaller cards get a roughly 20 percent performance hit on average. So, with everything performing at a very, very high level, and little variation among them, factors like price and service weigh heavily.We will soon have a review available comparing this reader to the Delkin Devices card reader and the Angelbird card reader, both of which use USB 3.2 ports.] These are very, very good numbers by old metrics. So good, it would be poised to unseat the Sony TOUGH CFexpress Type B card that has been PetaPixel‘s recommendation for the last year.
