Name: SanDisk 43237-2 Ultra 32GB Micro SDHC Card - 98MB/s, 2-Pack
Brand: SanDisk
SKU: 43237-2

Overview

The SanDisk Ultra 32GB Micro SDHC 2-Pack delivers straightforward, dependable storage expansion for Android smartphones, tablets, and cameras. Each card carries a U1 and Class 10 speed rating, ensuring the sustained write performance needed for Full HD video recording and playback. The A1 app performance designation goes a step further, certifying that the cards meet minimum random I/O benchmarks for running applications directly from the card — a practical advantage on Android devices where internal storage runs short.

With transfer speeds up to 98MB/s, moving photos, videos, and files to a computer is quick and painless, and the included SD adapters extend compatibility to DSLRs, laptops, and desktops with full-size card slots. SanDisk's durability certifications — shockproof, waterproof, temperature-proof, and X-ray-proof — mean these cards can handle the rigors of daily carry, travel, and accidental exposure to the elements. The 2-pack format makes this an economical way to keep a spare card on hand or equip multiple devices at once.
