SanDisk 1 Tt Extreme Pro SDXC V60 UHS-II muistikortti

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.

These 256GB Extreme Pro SD cards work perfectly every time for the video that I shoot

Best balance of performance, reliability, and cost

Sandiskin muistikortit ovat luotettavia ja laadukkaita. Kyseinen muistikortti toimii juuri niin kuin pitääkin ja tilaa riittää hyvin myös pitkille kuvaussessioille. Erittäin hyvä muistikortti esim. videokuvaukseen.

Delivered exactly as promised, speedy and works perfectly
