We keep SanDisk 128GB Extreme microSDXC card +SD adapter, microSD on our memory cards & storage shelf alongside 49 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Save time with card offload speeds of up to 190MB/s powered by SanDisk QuickFlow Technology. READER SD and microSD to achieve maximum speeds (sold separately). That is the maker talking, not us, so read it as a claim rather than a finding. 101,244 ratings put it at 4.7 out of 5. The comparison with the rest of the shelf follows.
We track 50 rated memory cards & storage products, and the middle of that pack scores 4.6 out of 5. This one is on 4.7. That puts it in the top quarter of the shelf. Most things here rate well, so what matters is the gap to the pack rather than the number on its own, and the gap is real. Weighted for review volume, we place it first on this shelf.
That score rests on 101,244 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.
