Product identity

The SanDisk Ultra microSDHC card offers 16GB of storage with a Class 10 speed rating. It delivers a maximum read speed of 80MB/s for quick file transfers. The card uses the UHS-I interface and is sold without an adapter. It suits users needing basic removable storage for compatible devices.

Bundled accessories impact

No adapter is included in the package, so the card fits directly into microSD slots only. Users with full-size SD slots must source a separate adapter to use this card. The absence of bundled software means operation relies entirely on the host device's built-in file management. This keeps the package minimal and focused on the card itself.

Who this suits

This card works well for expanding storage in smartphones, tablets or action cameras that accept microSDHC media. It handles Full HD video recording and everyday file storage within its 16GB capacity. Buyers who need more space or faster sustained write speeds for 4K capture should consider higher-capacity or higher-class alternatives. Those requiring an adapter for immediate use in SD slots must purchase one separately.

Questions about this item

How many write cycles can the 16GB microSDHC card handle before it wears out?

The card uses standard NAND flash rated for typical endurance; with 16GB capacity and Class 10 write speed, normal use spreads writes across the full array so replacement is rarely needed for years.

What limits continuous recording at the 10MB/s write speed?

The Class 10 rating guarantees a minimum sustained write of 10MB/s; the limit that appears first is the card's own write-speed ceiling, not the UHS-I bus or the host device.

Does the card get hot or draw extra power during all-day video capture?

microSDHC cards draw very little current and have no moving parts; at the rated 10MB/s write speed they stay cool and consume minimal power even during extended recording sessions.
