Biwin bridges the gap between microSD portability and SSD performance with the launch of the Amber ME300. This new microSD Express card targets the next generation of handheld consoles, promising to kill long loading screens for good.
Desktop Speeds in a Small Form Factor
The ME300 utilizes the SD 7.1 specification and PCIe NVMe technology to hit speeds that dwarf traditional cards. It clocks in at 900 MB/s for sequential reads and 800 MB/s for writes. This means massive open-world games launch almost instantly and texture streaming stays fluid during high-intensity gameplay.
Gaming handhelds eat through storage fast. Biwin addresses this by offering the Amber ME300 in three distinct capacities:
- 256 GB
- 512 GB
- 1 TB
A single 1 TB card can house dozens of AAA titles, turning a portable console into a comprehensive digital vault.
Built for the Future
While the ME300 is a pioneer for upcoming microSD Express hardware, it won’t leave your current gear behind. It features full backward compatibility with UHS-I devices. You can buy the speed you need for tomorrow’s consoles while still using the card in your current Nintendo Switch or Steam Deck today.

Biwin engineered these cards to survive more than just a software crash. They’re built to withstand:
- Water and Dust
- X-rays and Shocks
- Accidental Drops
Every unit undergoes rigorous environmental stress testing to ensure your save files don’t vanish if you drop your bag or spill a drink.
