Product details
SanDisk Extreme GO microSD 128GB Memory Card is a 128GB microsdxc intended for capturing compatible 4K footage and managing files on action cameras, drones and Android devices. A newer Extreme GO generation with distinct 128GB and 256GB write-speed ratings. This listing refers to manufacturer model SDSQXGN-128G-GN6MN, so its capacity and performance should be compared with that exact model rather than another product in the same brand.
Performance and everyday use
Read speeds are rated up to 240 MB/s, with writes up to 120 MB/s. These figures describe the drive or card under the manufacturer’s test conditions. They are not a promise that every file copy will reach the same rate. The host connection, compatible reader or cable, file sizes and workload affect real transfer times. The Class 10 / U3 / V30 / A2 classification specifies a minimum sustained writing level of 30 MB/s for the relevant recording class; it is different from the maximum read rating. Check your camera’s requirements for the recording mode you intend to use.
Compatibility and design
Compatible microSDXC action cameras, drones, Android and handheld gaming devices; compatible SanDisk QuickFlow reader required for peak read performance. UHS-I is the specified interface for this model. Check the host’s supported capacity and connection before installation or use. Some usable capacity is reserved for formatting and system management, so the space reported by a computer will be below the nominal 128GB label.
Why choose this model?
Removable memory card. A2 application and U3/V30 video ratings on official artwork. The product is intended for capturing compatible 4K footage and managing files on action cameras, drones and Android devices. Handle the connector and storage contacts carefully, and keep a separate copy of important data. Manufacturer durability claims describe specified test conditions and do not replace a backup or guarantee protection from every accident.
