As devices become thinner and AI-driven workloads demand higher bandwidth, traditional eMMC and UFS storage are hitting their limits. Biwin is addressing this bottleneck with the launch of the CL100 Mini SSD and the RD510 Reader—a duo designed to bring PCIe 4.0 performance to an ultra-compact, “SIM-card-style” form factor.
Big Performance, Tiny Footprint
The standout feature of the CL100 Mini SSD is its physical size. Measuring just 15.0 x 17.0 x 1.4 mm, it is roughly the size of a coin. Despite its diminutive stature, it utilizes advanced LGA packaging to integrate the controller and flash memory, delivering speeds that rival full-sized desktop drives.
The innovation hasn’t gone unnoticed; the technology behind this drive recently earned a TIME “Best Innovation of the Year” award.

| Durability | IP68 (Water/Dustproof), 3-meter drop resistance |
RD510: Unlocking USB 4.0 Speed
To complement the CL100, Biwin introduced the RD510 Mini SSD Reader. Featuring a unique “slot-in” tray design similar to a smartphone’s SIM tray, the RD510 transforms the CL100 into a high-speed external drive.

Utilizing USB 4.0 connectivity, the reader maintains impressive throughput, reaching up to 3,300 MB/s read speeds. It is designed for cross-platform versatility, offering plug-and-play compatibility with Windows, macOS, Android, iOS, and even the PlayStation 5.
Targeted use cases:
- Handheld Gaming: Ideal for expanding storage on devices where internal space is at a premium.
- Content Creation: Fast enough for 4K/8K video editing directly from the drive.
- AI Workflows: Provides the high-speed data ingestion required for large-scale AI datasets in a portable format.
The Biwin CL100 and RD510 represent a significant shift in portable storage, proving that you no longer have to sacrifice high-end NVMe speeds for a pocketable form factor.
