Overview

Amazon Basics microSDXC Memory Card with Full Size Adapter sits on our memory cards & storage shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: Compatible with Nintendo Switch (NOT Nintendo Switch 2). Always check your device's max supported capacity. World Capacity - Labeled Capacities/Usable Capacities: 64GB/≥58GB; 128GB/≥116GB; 256GB/≥232GB; 512GB/≥465GB; 1TB/≥908GB (Due to OS formatting and binary/decimal calculation differences). That is the maker talking, not us, so read it as a claim rather than a finding. 97,314 ratings put it at 4.6 out of 5. The comparison with the rest of the shelf follows.

How it compares on the memory cards & storage shelf

We track 50 rated memory cards & storage products, and the middle of that pack scores 4.6 out of 5. This one is on 4.6. Mid-table, in other words. The stars aren't going to pick a winner here, so it comes down to pack size, cost per unit and the details further down.

That score rests on 97,314 ratings. The median for this shelf is 12,973. That's a deep enough base for the score to be stable, and it is the reason we rank on volume as well as stars.

Price-wise it falls in the middle third of a shelf that stretches £6.99 to £185, with £21.84 in the middle. That's the middle of the shelf, which is usually the least regretted place to buy from.
