512GB microSDXC card for Android

The SanDisk Ultra GO microSDXC 512GB card adds high-capacity storage to Android smartphones, tablets and digital cameras. It uses UHS-I interface with a rated read speed of up to 190MB/s. The A1 rating ensures faster loading of installed apps and games. NAND flash technology provides durable solid-state storage for everyday capture and playback.

Check device slot and file system

Verify that your device accepts microSDXC cards and supports the exFAT file system used at this capacity. Confirm the host can utilise UHS-I speeds to benefit from the quoted read performance. The card is formatted out of the box but may need reformatting in the device settings for optimal compatibility.

Replaces lower-capacity or slower microSD cards

Upgrading from a smaller card removes the need to delete files to free space for new Full HD video or large apps. Moving up from a Class 10 or non-A1 card reduces app launch times and improves sustained write performance during recording. The jump is worthwhile when internal storage is full or current transfer speeds feel sluggish.

Questions about this item

Does the SanDisk Ultra GO microSDXC 512GB card come with an adapter or reader, or must I buy one separately?

The card is sold on its own; a microSD-to-SD adapter or USB reader such as the SanDisk QuickFlow USB-A reader is purchased separately if your device lacks a microSD slot.

The specs list UHS-I A1 C10 V10 — which rating should I check to match my Android phone or camera?

Check your device manual for UHS-I, Class 10, or V10 support; this card meets all three, and the A1 rating means it can run apps directly from the card on Android.

The box says up to 190MB/s read — what speed will I actually see when copying files to my laptop?

Real-world read speed depends on your reader and USB port; with a UHS-I reader on USB 3.0 you can approach the 190MB/s figure, while older ports will be slower.
