Score: 53/100
SanDisk Ultra 64GB
Score: 75/100Rankings

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.

The Kingston 4 GB microSDHC Class 4 card offers robust waterproof and shockproof protection with a lifetime warranty, making it reliable for basic storage needs. However, its low 4 MB/s transfer rate and limited 4 GB capacity restrict performance for modern high-resolution media. Best suited for users of older devices needing a small, durable card.
