Overview

The SanDisk Extreme 32GB microSDHC UHS-I card is designed for users who need dependable speed in a compact format. Rated at UHS Speed Class 3 (U3), Video Speed Class 30 (V30), and Class 10, it guarantees a minimum sustained write speed of 30MB/s, which is the threshold required for smooth 4K UHD video recording. Sequential read speeds reach up to 90MB/s and write speeds up to 60MB/s, enabling quick file transfers when moving footage to a computer or other storage. This performance profile makes the card well-suited for GoPro action cameras — SanDisk specifically recommends it for the HERO, HERO3, HERO3+, HERO4, HERO5, and HERO+ LCD — as well as Android smartphones and tablets that benefit from fast external storage.

The card ships with a full-size SD adapter, extending its usefulness to DSLR cameras, laptops with SD card slots, and standalone card readers. SanDisk backs the Extreme 32GB with a lifetime warranty, reflecting confidence in the card's durability and long-term reliability. While the 32GB capacity is modest by current standards — holding approximately one hour of 4K footage or several thousand high-resolution photos — it remains a practical and cost-effective option for users who rotate cards during shoots or who primarily use it for day-to-day mobile storage where massive capacity is not essential.
