Sandisk Ultra microSDXC 512GB Class 10 U1 A1 UHS-I
Differenze e somiglianze principali
A2 vs A1 Application Class: Samsung Evo Plus faster for app loading
The Samsung Evo Plus (2021) is rated A2, while the Sandisk Ultra is rated A1. In practice, A2 cards deliver significantly higher random read and write IOPS, making the Samsung model better suited for running apps and games directly from the card in devices like smartphones and tablets.

U3 vs U1 UHS Speed Class: Samsung Evo Plus handles 4K video recording
The Samsung Evo Plus has a U3 rating, guaranteeing a minimum sequential write speed of 30 MB/s, which is required for 4K video recording and high-bitrate burst photography. The Sandisk Ultra is only U1 (minimum 10 MB/s), limiting its use to full HD video and less demanding tasks.

V30 vs no V30 video speed class: Samsung Evo Plus certified for 4K video
The Samsung Evo Plus includes a Video Speed Class rating of V30, ensuring it can reliably sustain 30 MB/s write speeds for 4K video. The Sandisk Ultra lacks any Video Speed Class rating, which means it may not meet the requirements for consistent 4K recording.

Claimed read speed: Sandisk Ultra 150 MB/s vs Samsung Evo Plus 130 MB/s
Sandisk rates the Ultra for up to 150 MB/s sequential read speed, while the Samsung Evo Plus (2021) is rated for up to 130 MB/s. While both are UHS-I bus-based, the Sandisk claims a 15% faster sequential read performance on paper.

Write speed specification: Sandisk claims 150 MB/s; Samsung does not specify
Sandisk explicitly lists a write speed of 150 MB/s for the Ultra model. The Samsung Evo Plus product data does not include a write speed specification, making it less transparent about write performance. However, note that both cards operate on the UHS-I bus, which has a theoretical limit of 104 MB/s; real-world sustained write speeds for both are typically lower than these claimed values.

Recommended use: Sandisk Ultra is narrower; Samsung includes action cameras
Both cards are recommended for smartphones, tablets, and gaming. However, the Samsung Evo Plus also lists action cameras as a recommended use case, whereas the Sandisk Ultra does not — likely due to the Samsung model's higher write performance rating (U3/V30) better suited for continuous high-bitrate recording.
