Choose the Capacity Your Device Supports
The available options are 512 GB and 1 TB. Both are microSDXC cards, so check the device’s maximum supported capacity before selecting one. The larger option gives more nominal room for files; usable space is lower after formatting, and actual recording time depends on media settings.
Up to 150 MB/s Read Performance
The two listed SDSQUAC variants support reads up to 150 MB/s using SanDisk’s proprietary technology with compatible equipment. This exceeds the conventional UHS-I limit and needs a suitable host or reader to reach the rated maximum. Real transfer rates depend on the host, files and operating conditions.
A1 for Compatible Application Workloads
The A1 rating addresses application performance on supported devices, including the small random reads and writes used by apps. It is useful when the host permits application storage on a memory card. Operating-system policies still determine which apps and files can be placed on external storage.
Class 10 for Full HD Video
Class 10 and UHS Speed Class 1 support suitable Full HD recording workloads. The camera or device must support the selected capacity and recording mode. A maximum read-speed rating does not establish support for every high-bitrate video format, so follow the recorder’s card requirements.
Move and Organise Your Files
Use a compatible microSDXC reader or the host device’s transfer function to copy files to a computer. Keep projects and media folders organised by session, then verify the copies before freeing space on the card. The reader and computer connection also affect the transfer speed.

Keep the Storage Ready for Everyday Use
Follow the host’s formatting and safe-removal instructions and let writes complete before taking the card out. Keep a separate copy of valuable media and documents. The microSDXC format makes the card easy to move, while supported capacity and file-system requirements remain specific to each receiving device.
Choose Storage Around the Actual Port
Check the supported interface, connector and the files or devices you plan to use. Match the cable and host port to the drive, and keep a separate backup for important files. Compare related options such as SanDisk Portable SSD V3 1TB, USB-C 1000MB/s or SanDisk Portable Drive 1TB, USB-C 600MB/s SSD, keeping the exact model and configuration in the decision. For the wider setup, explore Samsung 980 PRO PCIe 4.0 NVMe M.2 SSD and check the connection, size or mounting requirements before pairing accessories. Browse the SanDisk range at AX for more choices.
