![]() Most videographers use UHS-I or UHS-II cards, both of which are supported. The MacBook Pro SD card slot supports any capacity, and four of the six speed ratings.Īlthough UHS-III would have been nice, these cards are not in common use due to their cost. ![]() But its in the adapter (and a MicroSD card) and I cant figure out. Oh, and some cards will, for some reason, be labeled as supporting a speed standard but cite some speed between the full- and half-duplex standard. My Early 2011 MacBook shows the correct amount of memory, etc but says SD card is lock. That’s because that’s the maximum full duplex speed (with one lane each assigned to upload and download), but most applications only require read or write at any one time – so they can also be used in half-duplex mode, where both lanes are used in a single direction to double the bandwidth. ![]() SD Express (HC/XC/UC): 985MB/s or 1970MB/s or 3940MB/sĪs if all that weren’t complicated enough, you will sometimes see UHS cards marked with half the speeds shown above.Ultra High Speed III (UHS-III): 624MB/s.MicroSD (requires an adapter for full-size SD card slots)įinally, speed rating (ones supported by the MacBook Pro shown in bold):.The situation with SD cards is complicated by the three different things you need to consider. MiDrive is compatible with MacBook Air/Pro computers with SDXC memory card support. Not as forward looking as UHS-III (over 600 MB/s) would be, but thank god it’s not UHS-I (about 100 MB/s). ![]() ![]() Verge deputy editor Dan Seifert got the confirmation.Īpple has confirmed to us that the SD card slot in the new MacBook Pro 14/16 is UHS-II (over 300MB/s). Apple has confirmed the specification of the new MacBook Pro SD card slot, and there’s reasonably good news for videographers.Īpple says that the slot supports UHS-II transfers, though not UHS-III or SD Express. ![]()
