64GB microSDXC card for mobile devices
The SanDisk Ultra microSDXC card delivers 64GB of removable storage in the compact microSD form factor. It is designed for smartphones, action cameras, drones and other portable electronics that use microSDXC slots. The card carries a U1 speed rating and Class 10 designation for reliable capture of Full HD video. No SD adapter is included in the package.
Thermals noise and power in typical use
As a solid-state memory card with no moving parts, the device produces no audible noise and generates negligible heat during normal read and write operations. Power draw is minimal, drawing only the small current supplied by the host device's card slot. This makes it well suited for battery-powered equipment where thermal and acoustic signatures must stay low.
Behaviour under sustained write load
The card supports a maximum read speed of 100MB/s and a write speed of 120.0MB/s, allowing continuous recording of high-bitrate Full HD footage without dropped frames. U1 guarantees a minimum sequential write of 10MB/s, so performance remains consistent during long capture sessions. Devices limited to the older microSD or microSDHC standards will not recognise this 64GB XC capacity card.

商品問答
How do I install the SDSQUNR-064G-GN3MN microSDXC card, and what step do people often miss?
Insert the card label-side up until it clicks into the device's microSD slot; the step many miss is confirming the host supports microSDXC 64GB capacity, as older devices limited to microSDHC 32GB will not recognise it.
What maintenance or replacement will this 64GB Ultra card need over time?
No scheduled maintenance is required; replace the card if write speeds drop below the U1 10 MB/s minimum, if read performance falls well under the rated 100 MB/s, or if the device reports read/write errors.
What limit appears first during sustained writing on this U1-rated card?
The U1 speed class guarantees a minimum sequential write of 10 MB/s; under continuous heavy writing the card will throttle to maintain at least that rate, making 10 MB/s the first sustained-use ceiling.
