Score: 78/100
ProGrade Digital V60 512GB
Score: 83/100Rankings
The ProGrade Digital 512 GB UHS-II SDXC card offers blazing 250 MB/s read speeds and a guaranteed V60 (60 MB/s) sustained write speed, making it ideal for 4K/UHD video and rapid RAW photo bursts. However, its maximum write speed tops out at 130 MB/s and performance falls back to U3/V30 levels in legacy UHS-I slots. It is best suited for professional photographers and videographers who need rugged durability and fast off-loading in UHS-II-compatible devices.
Amazon Basics 1TB microSDXC delivers budget-friendly high-capacity storage with up to 100 MB/s read and 80 MB/s write, featuring IPX6 waterproof and shockproof protection. Speed can vary across devices and older hardware may face compatibility limits. Ideal for cost-conscious photographers and gamers needing large space.

Professional reviewers commend the Amazon Basics card for delivering sequential and random speeds that meet or surpass the SanDisk Extreme/Pro reference, maintaining cool operation during prolonged 4K/8K recording, and offering a compelling price-to-performance ratio.
Everyday users appreciate the card's accurate capacity, reliable adapter, and fast transfers without heat, noting it as a solid value for high-resolution media and app storage. Common themes include satisfaction with performance for typical use and occasional remarks about speed variability and the need to check device compatibility for larger capacities.
“performs faster than most high-end SanDisk cards”
“at least as good as, if not very slightly better”
“fast and cheap -- better than Sandisk”
Professional reviewers praise the card's near-spec read performance and reliable V60 sustained writes, emphasizing its cost-effective speed for 4K and RAW capture. However, they caution that the write speed ceiling and the steep performance loss in legacy UHS-I slots limit its suitability for the most demanding 8K workflows.
Consumer commentary is sparse; the few available mentions echo the professional view, highlighting fast reads and durability but offering no additional praise or complaints.
