The Fanxiang KM800 is a new 256GB microSD Express card that utilizes PCIe/NVMe-based interfaces to achieve high read and write speeds. It is marketed toward handheld gaming and high-performance storage needs, featuring significant durability protections.
Why it matters
This product represents a shift in mobile storage technology, bringing desktop-class interface speeds to the compact microSD form factor.
As games, videos, photos, and other files continue to take up more storage, having a reliable memory card is becoming just as important as having enough internal storage. The Fanxiang KM800 is designed for users who want more than basic expandable storage, bringing the newer microSD Express standard to a compact 256GB card.
Fanxiang claims up to 900 MB/s read and 810 MB/s write speeds, putting the KM800 well above the typical performance of conventional microSD cards. It also carries U3, V30, and A1 ratings, making it suitable for gaming, media storage, and other everyday workloads.
We tested the 256GB Fanxiang KM800 using both a tablet and PC, looking at its sequential and random performance and how it handles everyday storage tasks.
The Fanxiang KM800 uses the standard microSD form factor, so it fits into compatible devices just like a conventional microSD card.
