SanDisk Ultra 64GB
Score: 75/100
Lexar E-Series 256GB
Score: 81/100Rankings
Lexar's 256 GB E-Series microSDXC provides up to 100 MB/s read and 140 MB/s write speeds, IPX7 waterproofing and a broad compatibility range across smartphones, tablets and action cameras. However, its UHS-I performance cannot exploit the higher speeds of UHS-II devices, and some variants lack detailed temperature specs. It's a solid choice for mobile and action-camera users seeking rugged storage.
The SanDisk Ultra 64 GB SDXC card delivers solid read performance up to 99.5 MB/s and broad compatibility with major camera brands. Write speeds hover around 16-22 MB/s and it lacks higher video class ratings, limiting 4K use. Suited for casual to semi-professional photographers.

Professional reviewers view the Ultra as a budget-friendly option that delivers solid read performance but falls short on write speed. They note its suitability for users with modest bitrate needs while recommending the Extreme or Extreme Pro lines for demanding video or burst photography.
Everyday users generally express high satisfaction, praising the large capacity, reliability, and seamless camera compatibility. Complaints are minimal, with most reviewers reporting error-free operation and quick delivery.
Professional reviewers note that Lexar's high-end GOLD card provides the fastest UHS-II speeds suitable for demanding 4K/8K workflows, while the SILVER PLUS and PLAY cards offer solid V30 performance and rugged durability for action cameras and gaming consoles. The inclusion of an SD adapter and a lifetime warranty are repeatedly praised, though reviewers caution that UHS-II benefits require compatible host devices.
Everyday users provide limited feedback, but the few available comments praise the fast transfer rates and reliability for gaming and video storage. Some users express uncertainty due to the lack of detailed performance data, especially for the GOLD and PLAY variants.
