Rank #3 in Best 1TB microSD Card 2026: 10 Ranked, Read vs Write
SanDisk Extreme 1TB microSD Card + Adapter
Price and rating as shown on Amazon when we collected them. Both change.
The SanDisk Extreme 1TB is the number three card in this guide, at £157.99. That is £113 less than the 900 MB/s Lexar PLAY PRO at the top, and the two cards are not doing the same job: the Lexar's 900 MB/s applies only in a microSD Express slot, while this SanDisk is a UHS-I card — the listing's own Model Name reads "UHS I" — running at UHS-I speeds in a console, camera or drone.
The SanDisk Extreme 1TB is also where this guide's problem appears twice on one page. One bullet promises "Up to 130MB/s write speeds for fast shooting"; the spec table on the same listing gives "Media Speed: 20 megabytes_per_second". Write speed is what a camera, drone or handheld actually lives with, and this listing carries both a 130 MB/s claim and a 20 MB/s figure without reconciling them. The 190 MB/s read figure comes with its own condition in the next bullet: maximum speeds need the SanDisk Professional PRO-READER SD and microSD, which is sold separately. Everything on this page — price, specs, rating and review counts — is taken from the Amazon listing for this card, not from testing we carried out.

Questions people ask
Why does the listing give two different write figures?
One bullet on the SanDisk Extreme 1TB listing says "Up to 130MB/s write speeds for fast shooting", while the spec table on the same listing says "Media Speed: 20 megabytes_per_second". Both numbers come from the same Amazon page and we cannot say which applies in your device.
Does the SanDisk Extreme 1TB reach 190 MB/s read?
