Ideal for Android devices

The SanDisk Ultra microSDXC card delivers 64GB of storage for smartphones, tablets and MIL cameras. Rated UHS-I U1 Class 10, it offers read speeds up to 120MB/s for quick file transfers. The A1 rating ensures faster app loading and smoother performance on Android. A full-size SD adapter is included for broader device compatibility.

Suits mobile users needing app speed

This card is built for Android owners who want quicker app launches and reliable Full HD video capture. It is not suited for workflows that demand sustained write performance beyond the U1 rating. Users recording high-bitrate 4K video should consider cards with higher video speed class ratings. The bundled adapter adds flexibility for laptop or camera slots.

UHS-I U1 Class 10 with A1 rating

The speed class rating guarantees a minimum sequential write of 10MB/s, enough for Full HD recording and playback. A1 certification means the card handles random read and write IOPS for responsive app operation. Read speeds reach 120MB/s, moving up to 1000 photos per minute. The 64GB capacity balances space and cost for everyday mobile storage.

Questions about this item

How many write/erase cycles can the 64GB Ultra microSDXC card handle before it needs replacement?

SanDisk does not publish a cycle rating for this model; the card is covered by a limited lifetime warranty and built with wear-levelling firmware to extend usable life under normal Android smartphone and tablet workloads.

What is the minimum sustained write speed the U1 and Class 10 ratings guarantee during long Full HD video recording?

Both U1 and Class 10 certify a minimum sequential write of 10 MB/s, so the card will maintain at least that rate for continuous Full HD capture.

How much power does the card draw and does it get hot when transferring at the 120MB/s read speed all day?

MicroSD cards typically draw under 100 mA during reads and stay near ambient temperature; the Ultra series has no active cooling and is rated for the standard operating temperature range.
