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

Product Information

Other features include a magnetised bottom for connecting it to your laptop and an LED indicator to indicate transfer activity. Some readers use a USB cable that’s hard-wired to the reader body, which can be problematic if the cable ever gets damaged. This is a device that has been designed in a unique manner to ensure that you are allowed to ingest, edit and even reach the extent of archiving any content that you have made in a creative manner. It is one of the greatest because it ensures that this is all done with the best known speeds of the content. The metal closure is one that is rugged hence ensuring durability and also longevity. We highly recommend this as the top best XQD card reader for 4K video workflow. However, where the Cobalt cards really shine is that ProGrade doesn't just advertise their peak read/write speeds, it actually guarantees the minimum sustained write speed (host device permitting). In this case, that's 1400MB/s - just 100MB/s shy of the 1500MB/s max write rate, which is hugely impressive. Two capacities are offered - 325GB and 650GB - and both are 'reassuringly' expensive for their size, but when has top performance ever been cheap?

With many current high-end cameras now utilizing both the CFexpress and SD card formats, it makes sense to get a card reader that also takes both standards. This offering from Prograde Digital is a high quality choice and an ideal match for today's mirrorless and DSLR cameras. Our CFexpress Type B Card Reader MK2 processes data at uninterrupted transfer speeds using a USB-C 3.2 Gen 2x2, 20 Gb/s based recessed connection logic. It has to be said that the CFexpress format is a leap forward. The cards are all so fast that the difference between the top performer in clearing a full buffer and the card that came in second from last is just 1.5 seconds. The buffer is that on-board, super-fast memory that fills up, and then you’re just left with the raw speed of your memory card, chewing through what the buffer can upload to it. These are the best memory card readers to supercharge your SD, CFexpress & XQD memory card image transfers 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.]Kingston’s MobileLite Plus SD reader supports UHS-II and UHS-I SD cards and delivers fast data transfer speeds thanks to its USB 3.2 technology. Smooth and efficient workflow is all that is needed in day to day activities of taking videos, transferring them and pictures too. What should be noted also is that the actual performance will also vary depending on the device that will be used. Don’t let the action go, snap it and record it. It never fails users and when you have it, then you are sure that everything you have planned will just go as planned UGREEN SD Card Reader USB 3.0 Card Hub Adapter 5Gbps Read 4 Cards Simultaneously ProGrade Digital’s SD Dual-Slot USB 3.1, Gen. 2 Card Reader is compatible with both UHS-I/UHS-II. It also includes two 18-inch connection cables: one Type A to Type C and one Type C to Type C. This change in memory card type means that many photographers are having to change their memory card reader. The Sony MRW-E90 XQD/SD card reader is an attractive option as it has two slots, one for XQD cards and the other for SD-type media.

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.] 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. ConclusionAt least the USB 3.1 Gen 2 (10 Gbps) interface is speedy, equating to a maximum transfer speed of 1250 megabytes per second. However, even this is still some way short of the 1700+MB/s read speed that the best CFexpress cards can manage. even this can't let the fastest CFexpress Type B cards run at max speed. 5 things to look for in a card reader 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. 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.

If you shoot video, or if you photograph sports, news or other fast-moving events, XQD is the memory card format for you. CFexpress Type A cards first appeared on the market when Sony launched the a7S III mirrorless camera. Sony has continued to add compatibility for this card type to their new camera models, including the Sony a7R V, Sony a1, Sony a7 IV and the Sony FX30, FX3, FX6 Cinema cameras. Other camera manufacturers are likely to follow suit, making CFexpress Type A cards a more prevalent choice in the industry. 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. In conclusion, CFexpress Type A card readers have become increasingly important for professional photographers and videographers who require fast and reliable data transfer speeds. After reviewing several options, the ProGrade Digital CFexpress Type A & UHS-II SDXC Card Reader, Sony MRW-G2 CFexpress Type ASD Memory Card Reader, and Delkin Devices CFexpress Type A & UHS-II SDXC Memory Card Reader stood out as the top three choices.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 streamlining of laptop designs and expansion of memory card formats has led to the rise of memory card readers. From memory card readers dedicated to one card type to multi-use, all-in-one devices, there are all sorts of memory card readers out there to suit your needs as a photographers.

With USB 3.1 Gen2 speeds 3 the SanDisk Extreme PRO® CFexpress® Card Reader optimizes the performance of the CFexpress® Card Type B 2 for smooth, efficient workflow from location to post production. Our CFexpress Type B Card Reader comes with a Write-Protect Switch that protects against unintended file deletion and keeps your system from writing unwanted data files to your card.

Specifications

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. The compact device boasts a durable design with rubber covers on the end to help protect it from being dropped. This also means you can safely store your CFexpress card inside. Below, is a table of the claimed maximum write and read speeds of the cards. As discussed earlier, dynamic heat reactions prevent there being a real minimum write speed figure, but even so, these maximum speeds show the manufacturers being pretty generous with themselves. These numbers are an industry convention that doesn’t have a great deal to do with actual card performance. To round out the table, we added a couple of additional rows with information just slightly more useful than the marketing claims. A critical factor – perhaps the most important for sports and wildlife shooters – is the number of shots you can rip before you get the unpredictable stutter of a full cache. In mechanical shutter at 12 FPS, the R5 will give you between 10 and 15 seconds of glorious, uninterrupted shooting. This is the sum of the buffer and the number of shots a card can manage to ingest while the buffer is filling. The Delkin consistently took the lead here.
