Questions about this item

Does the 128 GB microSDXC card come with an adapter or do I need to buy one separately?

The card is supplied on its own; a microSD-to-SD adapter is not included and must be purchased separately if your device requires a full-size SD slot.

Should I pick the 128 GB model or a larger 512 GB version for hours of Full HD video?

The 128 GB capacity holds several hours of Full HD footage; choose 512 GB only if you need space for many more hours or a larger media library.

Will I actually see the advertised 140 MB/s read speed when the card is in my Chromebook?

The 140 MB/s figure is a maximum transfer rate; real-world speed depends on the Chromebook's UHS-I interface and file sizes, so sustained rates are usually lower.
