The BIWIN Amber ME300 is the fifth card in this guide: a 1TB microSD Express card at £244.99, listed at up to 900MB/s read and rated 4.4 out of 5 from 85 Amazon ratings. It is the second card here that names the 900 MB/s figure — the guide's most expensive card, at £270.99, is listed at the same 900 MB/s peak, which makes this one £26 less for the same claim on paper. The listing describes it as SD 7.1 with a PCIe Gen3x1 interface alongside UHS-I, and puts Switch 2 first in its compatible devices.

The number worth stopping on is inside the listing's own spec table. The title and bullets say 900MB/s read; the table lists a Media Speed of 800 megabytes_per_second. That is two figures for the same card, 100 MB/s apart, and neither of them is a write speed — no write figure appears anywhere in the details we have. The same 900 MB/s applies only in a microSD Express slot, because the card is sold as backward compatible with UHS-I devices, where UHS-I speeds are what you get. Everything on this page comes from the Amazon listing and its spec table; nothing here was measured by us.
