The Integral 128GB SDXC card sits sixth in this guide to 128GB SD cards. At £25.95 it is one of the dearer cards in the set, and it carries a strong record: 4.5 out of 5 from 12,645 ratings, with 74 of the 100 ratings shown in the breakdown sitting at five stars and 4 sitting at one star.

The finding for this card is inside its own model number. The model is given as INSDX128G-100/90V30, which reads as 100MB/s read and 90MB/s write. The bullets in the same advert say "up to 100MB/s read speed and 50MB/s write speed", and the media speed field is listed as 50. Two of those numbers agree with each other; the 90 in the model number turns up nowhere else in the advert. Everything below — speeds, capacity, compatibility, warranty — is taken from the Amazon listing as it stands, not from any testing we have done on the card.
