For that matter, most users won’t be using a pro-grade card even 1/3 as fast as the Lexar Professional 2000X 64GB SDXC.īut as a professional photographer, when I am shooting huge raw files and a day’s shoot is 30GB or more, I do care, especially after hiking back from a grueling dawn to dusk outing and I haven’t eaten and want to get some shuteye. Of course most users shooting JPEG just won’t care about speed much, since 90 MB/sec is quite fast and JPEGs (even 50 megapixel JPEGs) are not all that large. Attached to the 2016 MacBook Pro, I wondered how the SD slot would fare versus the card slot on the 2015 MacBook Pro (my travel laptop), and how both would fare versus a dedicated high-speed SDXC card reader, the Lexar Professional USB 3.0 Dual-Slot Reader UDMA 7.
