SanDisk 256GB SDXC Extreme Pro V60 UHS-II geheugenkaart

The product generally lived up to its performance claims, but failed to completely fulfill them, despite being tested on a 2025 Apple M3 Ultra workstation with a data transfer capacity far in excess of the claimed write and read speeds. Perhaps the fault lies with MacOS (Sequoia 15.6), as the SanDisk tech finger-pointed when I discussed this issue with him, but nothing was offered to substantiate that. And yes, I verified with Apple that the unit's memory card slot is UHS-II and no, there was nothing between the card and the reader - it was directly inserted in the slot on the front of the machine. Actually, if SanDisk had just advertised the speeds that I got, I would have given it five stars, but I won't reward what amounts to less than frankly honest advertising about device performance.
