64 GB microSDHC for action cameras

The Ackmioxy 64 GB Extreme microSDHC UHS-I card delivers up to 100 MB/s read speed with C10, U3, V30 and A2 ratings. It targets creators who record 4K video on drones, action cams or OSMO Pocket units and need sustained write performance. The bundled adapter lets it slot into full-size SD devices.

Upgrading from slower Class 10 cards

A jump from a basic Class 10 or U1 card is worth it when 4K footage drops frames or burst shooting stalls. The V30 rating guarantees 30 MB/s minimum sequential write, so high-bitrate streams stay intact. Buyers who only shoot 1080p or store documents will not see a practical benefit.

Simple drop-in with adapter

Insert the microSD card into the included adapter, then into the device slot; no drivers or formatting tools are required. The most common issue is using a legacy card reader that caps transfer at USB 2.0 speeds, masking the card’s true throughput. A modern UHS-I reader restores full performance.

Questions about this item

Does the 64 GB microSDHC card need a full-size SD adapter to fit my camera?

The package includes an adapter so the microSDHC card can be used in full-size SD slots.

What is the correct way to insert the card so the U3 and V30 ratings actually work?

Insert the card label-side up until it clicks; the adapter must be fully seated in the host device before powering on.

When should I replace the card to keep 4K recording reliable?

Replace the card if write speeds drop below 30 MB/s or after roughly 360 TB of total data written.
