Twin 64GB MicroSDXC cards

This pack supplies two SanDisk Ultra microSDXC cards, each with 64GB capacity, for a combined 128GB of removable storage. They are Class 10 rated for Full HD video recording and playback on Android smartphones and tablets. The bundled SD adapters let you use the cards in standard SD slots for easy file transfers.

Plug in and format

Insert the card into your device or the supplied SD adapter; most phones and PCs recognise it immediately without extra drivers. The SanDisk Memory Zone app, free on Google Play, helps move files off internal storage automatically. If a device does not see the card, try formatting it in the device settings before use.

Class 10 ceiling

The Class 10 rating guarantees a minimum sequential write speed suitable for Full HD video, but it does not support higher bit-rate formats such as 4K. Maximum read speed reaches 80MB/s, so large transfers to a PC are quick, yet sustained write performance will not meet the demands of professional video workflows.

Questions about this item

How can I confirm the cards are delivering the rated 80 MB/s read speed after I insert them?

Use a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a PC with the supplied SD adapter; a sequential read result near 80 MB/s shows the cards are performing to spec.

What exactly is included in the retail pack and do I need to buy anything else to use the cards?

The pack contains two 64 GB microSDXC cards and one full-size SD adapter; no extra accessories are required for phones, tablets, cameras or card readers.

Should I choose this 64 GB x 2 pack or a single larger card for my Android phone?

The twin 64 GB cards give 128 GB total with the flexibility to swap cards between devices or keep one as a spare; a single larger card only makes sense if your device supports capacities above 64 GB and you prefer not to swap.
