  • 32 GB capacity stores thousands of photos and videos
  • Read speed up to 100 MB/s moves files quickly

Capacity and speed class

This 32 GB microSD card carries UHS-I U3 and V30 ratings with 100 MB/s read and 60 MB/s write speeds. It targets enthusiasts and creators who need reliable 4K UHD video capture and fast app loading on Android devices, laptops and handheld consoles. The A2 rating helps apps launch and run smoothly.

Installation and common pitfalls

Insert the card into a compatible microSD slot and format it with the host device before first use. The most frequent issue is using a reader or adapter limited to UHS-I speeds below U3, which prevents sustained 4K recording. Avoid removing the card while the activity light is on to prevent file-system corruption.

Compatibility checks before ordering

Confirm the host device supports microSDXC UHS-I U3 or V30 and can sustain 60 MB/s write for 4K workflows. Verify the slot accepts cards up to 32 GB and that the firmware recognises the A2 command set for app performance. Check whether your device requires a full-size SD adapter, which is not included.

Questions about this item

How can I verify the card is delivering the rated 100MB/s read and 60MB/s write speeds after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a PC or compatible device; the sequential read result should approach 100MB/s and the sequential write result should approach 60MB/s for this 32GB model.

What comes in the box and is a card reader or adapter required separately?

The package contains the 32GB microSD card only; a microSD-to-SD adapter is not included and a USB card reader must be purchased separately if your device lacks a built-in slot.

Which capacity should I choose among the 32GB, 128GB, 256GB, 512GB and 1TB versions?

Select 32GB for light use such as documents or occasional photos; step up to 128GB or 256GB for regular 4K video and app storage; choose 512GB or 1TB for extended 5K recording sessions and large game libraries.
