U3 has largely been supplanted by the newer and slightly less confusing “V” video speed class mark.)Īfter the Dell, the XPG Xenia 15 doubles the performance of the G5 15 SE with about 91MBps read speeds. Yes, they seriously have U3 and UHS-III which don’t mean the same thing. U3 refers to the card’s “UHS Speed Class” mark for video performance of a camera and card.
(And no, don’t confuse UHS-III (the bus) with the U3 symbol. Searching just last week, we saw no signs of a UHS-III card for sale.

If you’re wondering why we’re not using an even faster SD card using the newer UHS-III bus, it’s because we couldn’t find a card that even supported the newer interface, which takes speeds to 312MBps in full duplex mode and 624MBps in half duplex mode. The SanDisk Extreme Pro SD Card is rated for read speeds right up to the limit of UHS-II at 300MBps with write speeds rated at 260MBps. We used a 128GB SanDisk Extreme Pro card rated for 300MBps reads and 260MBps writes for our testing. We formatted the card in exFAT, which has seemingly become the standard for most large-capacity SD media. The UHS-II bus can hit 312MBps in full duplex mode and 624MBps in half-duplex mode. The card is a UHS-II card, meaning it rides on the Ultra High Speed II bus and features a second row of contact pins on the back to hit the higher performance ratings of the interface. In the meantime, if you're considering buying this machine, make sure to take a look at our in-depth 14-inch MacBook Pro review and 16-inch MacBook Pro review for more guidance.Because this test would be pointless without a fast SD card, we used a 128GB SanDisk Extreme Pro SD card.

We've reached out to Apple for additional comment and will update this article should we receive a response. Hopefully similar issues don't crop up in the rumored 2022 Pro XDR display with custom Apple silicon.
Just a week ago, we reported on users having problems with MagSafe charging and external monitor connectivity on their 16-inch MacBook Pros. This wouldn't be the first time we're hearing of problems with the new MacBook Pros.

However, many users agreed that using an external SD card reader via USB-C seems to be working better than the actual SD card slot in the MacBook Pro.Īccording to MacRumors, Apple has responded to some of the reported complaints and said that "the company is aware of the issue and that a fix is coming in a future software update." However, at this stage, it's hard to say whether the problem is hardware-related, considering some users were able to fix their issues by replacing their MacBook Pros. And based on the inconsistency of the reports, it's hard to distinguish what seems to be the primary cause behind all this. There's also no clarity on what cards seem to work fine and which are problematic. Apparently formatting the card doesn't seem to help and users have specified that their cards "work as expected" with other readers.Īnother user reported issues such as constant error messages, slow loading speeds when reading an SD card, and even the Finder tool crashing - all despite using "a fairly new 64GB SD card which had been working fine." Half the time it'll recognize the card successfully (though it takes anywhere from 30s to 1m) and half the time it'll throw an error," the user explained. "Just seems to be super flakey and inconsistent.
