Overview

The SanDisk SDSQUAR-200G-GN6MA 200GB Ultra microSDXC card was designed to provide generous storage expansion for Android smartphones, tablets, and compatible cameras. With 200GB of capacity, it can hold extensive libraries of Full HD video, high-resolution photos, music, and applications without requiring constant file management. The UHS-I interface delivers read speeds of up to 100MB/s, which translates to transferring approximately 1,000 photos per minute when used with a USB 3.0 card reader — making the process of backing up or moving content between devices efficient.

The A1 Application Performance Class rating distinguishes this card from basic storage-only microSD cards. With minimum random read performance of 1500 IOPS and random write performance of 500 IOPS, apps installed directly on the card launch and operate more responsively than they would on a non-A1 rated card. The included SD adapter extends compatibility to devices with full-size SD card slots, adding flexibility for camera use and desktop transfers. While this specific model has been discontinued by SanDisk, it remains a capable and reliable storage solution for devices that support the microSDXC format.

Frequently Asked Questions

This card is designed for Android smartphones, tablets, and MIL cameras. It uses the microSDXC form factor and includes an adapter for use in standard SD card slots.
The A1 rating indicates the card meets minimum random read (1500 IOPS) and write (500 IOPS) performance standards, which means apps installed on the card load and run faster compared to cards without this rating.
No, this version of the SanDisk 200GB Ultra microSDXC has been discontinued by the manufacturer. It may still be available through remaining stock from retailers.
While marketed as 200GB, the actual user-accessible storage is less than 200GB. This is because 1GB is calculated as 1,000,000,000 bytes by the manufacturer, while operating systems use a binary definition that results in a lower displayed capacity.
The card supports up to 100MB/s transfer read speed, though actual performance may vary depending on the host device, USB reader, and other factors.
