2021 MacBook Pro SD card slot supports over 300MB/s transfer speed

Apple’s new 2021 14-inch and 16-inch MacBook Pro SD card slot is SDXC (Secure Digital eXtended Capacity), but the company did not mention the supported transfer speeds. However, we now know that the SD card slot supports 312MB/s transfer speed, which means that its bus interface is UHS-II.

2021 MacBook Pro SD card slot is UHS-II

Dan Seifert from The Verge posted on Twitter that Apple confirmed to him that the new SD card slot is UHS-II, which means that the supported transfer speed is up to 312MB/s. To take advantage of these speeds, users will need to use UHS-II compatible SD cards.

Despite the latest and greatest features such as Thunderbolt 4 and USB4, the SD card slot’s UHS-II interface is not the fastest one that is available right now. There are faster speeds available such as UHS-III and SD Express, which support speeds up to 624MB/s and 3940MB/s respectively.

The new MacBook Pro models are available for pre-order now with M1 Pro and M1 Max chips, mini-LED displays, HDMI port, three Thunderbolt 4 USB-C ports, support for up to 64GB memory, up to 8TB storage, MagSafe 3, and fast charging which can charge the new machines up to 50% in just 30 minutes.
