Capacity and class

This 128 GB microSDXC card carries a Class 10 and UHS-I U1 rating, delivering up to 140 MB/s read and 10 MB/s write. It targets smartphone and tablet owners who need more space for photos, apps and Full HD video. The A1 rating means Android applications launch faster and run more smoothly on the card. An SD adapter is included for use in larger slots.

Sustained transfer behaviour

Sequential reads reach 140 MB/s, allowing roughly 1000 photos to be moved in about a minute, while writes hold at 10 MB/s during long captures. The U1 guarantee keeps minimum write performance steady for continuous Full HD recording without dropped frames. App execution stays responsive because the A1 spec enforces consistent random I/O, not just peak bursts.

Deciding specification

The 10 MB/s sustained write speed is the figure that determines suitability; it covers Full HD video and Android app storage but will not satisfy 4K recording or high-bitrate workflows that demand faster sequential writes.

商品問答

Does the card generate noticeable heat or draw much power when recording Full HD video all day?

Flash memory has no moving parts, so the Ultra microSDXC runs silently and stays cool during continuous Full HD capture.

Which host slot and file system are required to use the full 128 GB capacity?

A microSDXC-rated slot and exFAT formatting are needed; older microSDHC readers will not recognise the full capacity.

Will the A1 rating improve app launch speed on an older Android phone that only supports UHS-I?

Yes, the A1 spec works with any UHS-I host, so older Android devices still benefit from faster random reads for app loading.
