China’s Mini SSD Redefines Portable Storage

Biwin has launched a groundbreaking Mini SSD that promises massive storage in an ultra-compact design. Measuring just 15 x 17mm and 1.4mm thick, it’s smaller than a US penny but offers storage capacities of 512GB, 1TB, and 2TB. Despite its tiny size, this Mini SSD delivers sequential read speeds of 3,700MB/s and write speeds of 3,400MB/s over PCIe 4x2. This makes it a serious contender against traditional M.2 drives while fitting comfortably into laptops, tablets, phones, and even cameras.

Mini SSD Performance vs MicroSD and SD Cards

When compared to standard storage cards, the Mini SSD clearly stands out. MicroSD Express cards, often used in devices like the Nintendo Switch 2, cap at around 985MB/s, while full-size SD Express cards reach up to 3,940MB/s—almost matching the Mini SSD, but at nearly twice the size. By contrast, Biwin’s Mini SSD offers similar performance in a fraction of the footprint, combining portability with speed. For users needing fast, compact storage, it represents a major upgrade over traditional card-based solutions.

Design and Compatibility of the Mini SSD

The Mini SSD’s size is so small that its slot resembles a smartphone SIM tray, making it easy to integrate into thin devices where space is limited. This tiny form factor allows manufacturers to add high-speed storage without redesigning devices around larger drives. It is compatible with a range of modern hardware, including laptops, tablets, cameras, and mobile devices, ensuring versatility for both personal and professional use.

Why Mini SSDs Could Be the Future of Storage

With speeds rivalling larger M.2 drives and a footprint smaller than a penny, the Mini SSD signals a shift toward ultra-compact, high-performance storage. As devices continue to shrink while demanding faster data access, solutions like Biwin’s Mini SSD could become standard in next-generation laptops, cameras, and mobile devices. It’s not just about size; it’s about delivering terabytes of storage without compromise on speed or reliability.
