SanDisk 256GB_TF_Extreme_R4 Micro SD Card GoPro Bundle

The SanDisk Extreme 256GB microSD is rated at Class 10, UHS-I U3, V30, and A2 — a combination that positions it specifically for the sustained write demands of 4K video recording. The V30 rating guarantees a minimum 30MB/s sustained write floor, the measurable threshold above which GoPro-class 4K capture remains stable without frame drops. The card's 90MB/s write ceiling provides meaningful overhead above that floor, accommodating the variable bitrate spikes that action footage generates when high-motion scenes are recorded. On the read side, 160MB/s enables fast file offloading when connected to a USB 3.0 host via the included microSD reader — a practical capability that reduces the time spent waiting for footage transfers before you can review or edit.

This bundle is built for action camera shooters who need a card they can leave mounted and forget about. The four-proof durability rating — temperature, water, shock, and X-ray — covers the realistic abuse profile of a card permanently mounted inside a GoPro across outdoor shoots, water sports, and travel. At 256GB, capacity is generous enough for full-day 4K sessions without mid-shoot card management. The included Everything But Stromboli USB reader is a practical addition that removes the need for an extra purchase before your first offload. This configuration is optimized for GoPro, DJI action cameras, and similar consumer-action formats; it is not positioned as a card for high-bitrate cinema cameras, which demand V60 or V90 write ratings the Extreme does not carry.
