Mini SSD vs microSD: A New Threat to Dominance?
- Shenzhen,China - Chinese storage manufacturer Biwin has unveiled a new solid-state drive (SSD) format dubbed the "Mini SSD," boasting remarkable speeds and a remarkably small form factor.
- Why it matters: Offers significantly faster speeds than microSD cards in a much smaller package, possibly improving performance in portable devices.
- The Mini SSD utilizes a PCIe 4x2 interface, achieving sequential read speeds of up to 3,700MB/s and write speeds of 3,400MB/s.
Biwin’s “Mini SSD” Promises Big Speed in a Tiny Package – But Faces an Adoption Hurdle
Shenzhen,China - Chinese storage manufacturer Biwin has unveiled a new solid-state drive (SSD) format dubbed the “Mini SSD,” boasting remarkable speeds and a remarkably small form factor. Measuring just 15mm x 17mm x 1.4mm – smaller than a US penny – the Mini SSD aims to revolutionize storage in portable devices like laptops, tablets, smartphones, and cameras. However, its success hinges on industry-wide adoption, a challenge Biwin will need to address through standardization.
The Mini SSD utilizes a PCIe 4×2 interface, achieving sequential read speeds of up to 3,700MB/s and write speeds of 3,400MB/s. This performance dramatically surpasses the 985MB/s ceiling of microSD Express, currently the fastest microSD standard. Capacities are available up to 2TB.
Why universal standards matter for adoption
Despite its impressive specifications, the Mini SSD faces a meaningful challenge: lack of standardization. The success of microSD serves as a crucial case study. When SanDisk introduced microSD (originally called T-Flash) in 2005, they immediately submitted the format to the Secure digital Association (SDA).This pivotal move opened the door for numerous companies to manufacture compatible cards, ultimately establishing microSD as the ubiquitous storage solution it is indeed today.
Without a similar commitment to open standards, Biwin’s Mini SSD risks becoming a niche product, limited by its exclusivity.
Here’s a comparison of storage speeds:
| Storage Format | Typical Read Speed (MB/s) | Typical Write Speed (MB/s) | Interface |
|---|---|---|---|
| microSD | Up to 95 | up to 90 | SDIO |
| microSD Express | Up to 985 | Up to 800 | PCIe |
| Biwin Mini SSD | 3,700 | 3,400 | PCIe 4×2 |
| Standard NVMe SSD | Up to 7,500+ | Up to 6,800+ | PCIe 4×4 |
the key takeaway is that while the Mini SSD offers a substantial performance leap over microSD,its future depends on collaboration and standardization. Biwin must decide whether to submit the format to the SDA or the PCI-SIG (the group overseeing PCIe standards) to foster broader industry support.
The mini SSD is a genuinely exciting advancement.The speed difference compared to microSD is substantial, and the form factor is incredibly compact. Though, history teaches us that technical superiority isn’t enough. SanDisk’s proactive approach with the SDA was critical to microSD’s success. Biwin needs to learn from that example. Without opening up the standard, the Mini SSD risks becoming a captivating but ultimately limited technology. The question isn’t if this technology is good, but how Biwin will ensure it becomes widely available.
