SanDisk SDSDQUIP-016G-A46 16GB Ultra Plus MicroSDHC Memory Card

The SanDisk Ultra Plus SDSDQUIP-016G-A46 is a 16GB microSDHC UHS-I card rated at 40 MB/s maximum sequential read and Class 10 / U1 write performance. To contextualize those numbers: the UHS-I bus provides a theoretical 104 MB/s bandwidth ceiling, and this card operates comfortably within the lower tier of that range — fast enough for HD video playback and responsive app performance, but not positioned for burst photography pipelines or high-bitrate recording demands. The U1 minimum 10 MB/s sustained write is the key specification for video users: it satisfies the minimum throughput requirement for uninterrupted 1080p recording, including 3D video formats. The card's physical durability ratings — waterproof, temperature-proof, X-ray-proof, shockproof — address real-world carry conditions rather than controlled lab use, and the included SD adapter extends the card's compatibility to full-size slots without additional accessories.

This card's natural home is in devices where storage expansion is needed but peak throughput isn't the priority: entry-level action cameras, dashcams, older smartphones, portable audio players, and secondary card slots where overflow capacity matters more than speed. The 16GB capacity, while modest relative to current card pricing, covers roughly 80–100 minutes of typical 1080p video or several thousand JPEG images — sufficient for defined use cases where the card is regularly offloaded. Power users running 4K-capable cameras or high-speed continuous shooting should look to U3 / V30-rated cards; for everyone else operating within 1080p and HD media workflows, the Ultra Plus 16GB delivers reliable, specification-matched performance backed by a lifetime limited warranty.
