And for the CF reader, we used a SanDisk Extreme CF card rated at 120 MBps (UDMA 7) to copy 7.7GB of JPEGS (402 files), since that cards capacity maxed out at 16GB. IDG.The answeras with everything else that needs to connect to the USB-Conly MacBook Prois an external USB-C SD card reader.
But which one As you would expect, third parties have rushed to create adapters for everything, including memory card readers. And to no ones surprise, the quality, specifications, and prices are all over the map. We tested six adapters that stood out among the field based on online reviews, word of mouth, and design. Choosing which reader is best for you depends a lot on what you need and how much youre willing to spend. For most people, that could turn out to be one of the least expensive of the bunch. Before you view the picks, you may want to consult our SD Card explainer to understand the stew of acronyms and jargon the industry uses to describe memory card storage and speed. But its fast. On one hand, the speed is due to its UHS-II compatibility, transferring up to a theoretical 312 MBps from UHS-II memory cards that include a second row of contacts from which to read data. In our real-world tests, we recorded an average throughput of 195.45 MBps for photos and 267.67 MBps for video; the latters increase is due to the reduced amount of overhead needed to copy nine files versus 684 files. That said, even when copying from more common UHS-I cards, which top out at a theoretical speed of 104 MBps, the SanDisk Extreme Pro UHS-II USB-C Reader bested the other adapters we tested. We also liked the fairly compact design, with its bendy neck and minimal footprint, although the angle of the case where you insert the SD card makes extracting a card less elegant than needed. But if youre shooting with a camera that works with UHS-II cards and you need the fastest copy turnaround, the cost is worth it. In our testing, we found an average throughput of 179.36 MBps for photos and 221.89 MBps when transferring video files. The Verbatim reader is a little more bulky, and sports a short cable for the USB-C plug, but it also features slots for SD and Micro SD cards. We expected to run into tradeoffs at this price, but the Cable Matters adapter was almost as fast as the SanDisk adapter. Our photos transferred at 82.17 MBps, while videos zipped along at 95.6 MBps. The adapter has dedicated SD and microSD card slots that can be used simultaneously, and a discrete LED to indicate the adapter is getting power. With dimensions of just 2.8 x 5.4 x 0.5 inches and a 6-inch cable, it doesnt add bulk to any bag. If you dont need UHS-II compatibility, the Cable Matters USB 3.1 Type-C Dual Slot Card Reader is the one to get. For photos, we timed three transfers of 12.9GB of JPEG and raw images (684 files) and averaged the results. For video transfer, we copied 31GB (9 files) from the same card. We also copied the same files using a SanDisk Extreme Pro SDHC UHS-II card rated at 280 MBps to test the difference that UHS II compatibility affords. And for the CF reader, we used a SanDisk Extreme CF card rated at 120 MBps (UDMA 7) to copy 7.7GB of JPEGS (402 files), since that cards capacity maxed out at 16GB.
