SanDisk 16G_TF_Ultra_R4BKEBS 16GB Ultra Micro SD Card

Name: SanDisk 16G_TF_Ultra_R4BKEBS 16GB Ultra Micro SD Card
Brand: SanDisk
SKU: 16G_TF_Ultra_R4BKEBS

Overview

The SanDisk 16GB Ultra microSDHC card is a straightforward, budget-friendly storage expansion option designed primarily for Android smartphones and tablets. Carrying an A1 app performance rating along with UHS Speed Class U1 and Class 10 designations, it delivers enough throughput for Full HD video recording and playback, photo storage, and running apps directly from the card. Its compatibility extends well beyond the Samsung Galaxy S9 and S9+ that it is packaged with — any device accepting a standard microSDHC UHS-I card can use it.

SanDisk has built in protection against common physical threats, rating the card as shockproof, waterproof, temperature-proof, and X-ray-proof, which provides confidence when traveling or passing through airport security. The inclusion of an Everything But Stromboli combo card reader adds convenience for transferring files to a computer without hunting for a separate adapter. While the 16GB capacity is quite limited for today's media-rich workflows, it remains a practical choice for light storage needs, secondary backup, or as a spare card to keep in a bag.
