How we make money
We may earn a commission if you buy through links on this site. You don't pay any more. It never changes the numbers or the order of any list.
Which links earn us money
Links to retailers and to brands' own stores may be affiliate links. When you click one and buy, the retailer may pay us a share of the sale. Buttons that say "See price at" or "Check price at" are affiliate links. Links to testers' reviews and to makers' manuals are not.

What commission doesn't change
- Capacity figures come from independent tests and are calculated the same way for every model.
- Rankings are sorted by the data, never by commission rate.
- No brand pays to be listed, and no brand sees a page before it goes live.
- We include models we can't earn from.
