Rank #9 in Best 1TB microSD Card 2026: 10 Ranked, Read vs Write
SanDisk Ultra 1TB microSD Card + Adapter
Price and rating as shown on Amazon when we collected them. Both change.
The SanDisk Ultra 1TB sits ninth of ten in this guide. It is a microSDXC UHS-I card supplied with an adapter, rated Class 10, U1 and A1, and sold on the headline "Up to 150MB/s Read Speeds". It costs £109.99 and carries 4.6 stars from 132,166 ratings.
The listing gives you one number and never accounts for the other. "Read Speed" is stated as 150 Megabytes Per Second, and the specification table's "Media Speed" is a range of 0.4 to 150 MB/s — a floor of 0.4 MB/s is not a figure anybody buys a card for. No write speed is stated anywhere in the bullets or the specs, and write speed is what a console, camera or drone actually lives with. There is one further oddity worth knowing before you buy: the "Colour" field on this listing reads "Up to 150 MB/s".
