Buying Guide: What to Look for in a PNY Micro SD Card

Speed Class for 4K Video and Burst Photography

All three PNY cards reviewed here are Class 10, U3, and V30 rated. This means they support sustained write speeds of at least 30 MB/s, which is the minimum required for smooth 4K Ultra HD video. If you shoot in burst mode or record high-bitrate footage, these ratings ensure the card keeps up without dropping frames. For devices like the Surface Pro, you can find compatible micro SD cards for Surface Pro that also meet these speed standards.

App Performance: A1 vs. A2

App Performance Class determines how well a card runs apps directly from the storage. A1 provides a minimum of 1500 random read IOPS and 500 write IOPS, which is sufficient for most smartphones and tablets. A2 doubles those figures to 4000 read and 2000 write IOPS, making it ideal for heavy app users or those who run games and productivity tools from the card. The PNY 256GB PRO Elite is A2 rated, while both Premier-X models are A1.

Capacity: 256GB vs. 512GB

Choosing the right capacity depends on your storage needs. A 256GB card holds roughly 12 hours of 4K video or tens of thousands of photos, making it a solid middle ground. The 512GB option is better for users who shoot extensively or store large media libraries. Both capacities are available in PNY’s lineup, with the 512GB Premier-X offering the highest storage in this comparison.

Durability and Reliability

All PNY micro SD cards are built to withstand harsh conditions. They are magnet proof, shock proof, temperature proof, and waterproof. This makes them suitable for use in outdoor gear, dash cams, and security cameras. For more rugged storage options, explore the Cards category on our site.

What is the difference between A1 and A2 performance on a PNY micro SD card?
