The Lexar Professional 1667x takes second place in this guide, and it is the card here whose numbers hold together. The 128GB version is listed at £78.88, with 4.7 out of 5 from 14,247 ratings.

The bullet claims up to 250MB/s read and up to 120MB/s write. The spec fields agree: Read Speed is given as "250 Megabytes Per Second" and Media Speed as "120.0". The advert even pairs the 1667x name and the 250MB/s figure in the same sentence rather than in two different places. The one field that does not fit is Model Name, listed as "Lexar Professional Multi-Card 3-in-1" — that is a Lexar card reader, not an SD card, and the model number in the same advert (LSD128CB1667) is the card's own. Everything on this page comes from the Amazon listing, not from testing we carried out.
