The Lexar Silver 128GB is a UHS-I SDXC card that finished fifth in our guide to 128GB SD cards. It is also the card in that set whose headline number carries the biggest condition attached. The 205MB/s in the product title only applies with a Lexar RW310X card reader, and the listing says so in its own first bullet: "Must Use Lexar RW310X card reader to achieve maximum transfer speed. (Sold separately)." What the advert actually promises for shooting without extra kit is the 140MB/s write figure and the V30 rating.

At £43.19 for 128GB this is a considered purchase rather than an impulse one, and the listing carries a 4.6 average from 4,093 ratings. The way those ratings fall is worth a look: 77% are five-star and 13% are four-star, but 5% are three-star, 1% is two-star and 4% are one-star, so roughly one rating in ten sits at three stars or below. Every figure on this page — the specification fields, the bullet points and the customer quotes — comes from the Amazon listing rather than from testing we carried out ourselves.
