Chinese storage manufacturer Biwin has introduced a new 'Mini SSD,' a compact solution measuring just 15x17mm that offers high-performance sequential read speeds of up to 3,700MB/s and capacities up to 2TB via PCIe 4x2. This innovation aims to bridge the gap between slow MicroSD cards and larger M.2 drives, targeting portable devices such as laptops, tablets, and phones. The Mini SSD has already secured early adoption in two new Chinese gaming portables, signaling its potential to establish a new standard for high-speed, compact storage in the evolving mobile computing market.
A new 'Mini SSD' storage format, developed by Chinese manufacturer Biwin, presents a significant technological advancement in compact, high-performance storage. Measuring just 15x17mm, this SSD offers sequential read speeds of up to 3,700MB/s, a performance level more than triple the theoretical maximum of the upcoming MicroSD Express standard. This positions the Mini SSD to fill a critical market gap between the slower, smaller MicroSD cards and the faster but larger M.2 drives used in PCs. The technology has already gained initial traction, securing design wins in two high-end Chinese gaming portables, the GPD Win 5 and the OneXPlayer Super X, indicating early market validation in a demanding consumer electronics segment. However, critical uncertainties remain that will determine its broader market impact, including the lack of pricing information and, most importantly, whether this format will be adopted as an open standard or remain a proprietary solution. Its success hinges on its ability to offer a compelling cost-performance proposition and achieve widespread industry support beyond these initial niche applications.
