Lexar’s Muse is an ultra-slim portable SSD that’s less than 4mm thick

Lexar is set to release the Muse, an ultra-slim portable SSD measuring just 3.8mm thick. The drive achieves its thin profile by removing the traditional USB-C port, yet maintains high-performance speeds of up to 1,050MB/s.

The Evolution of Storage: Lexar’s Ultra-Thin Muse SSD

Lexar has officially announced the upcoming release of the Muse, an ultra-slim portable SSD that pushes the boundaries of hardware design. By measuring just 3.8mm at its thickest point and tapering down to a mere 1mm at the edges, the Muse represents a significant shift in how manufacturers prioritize portability and aesthetic form factor in the storage market.

The Trade-off: Form Over Function?

A notable development in the design of the Muse is Lexar's decision to sacrifice the integrated USB-C port, following a design trend recently popularized by companies like Xteink. While this removal allows for an unprecedented reduction in thickness, it raises questions about long-term durability and the necessity of external adapters. By prioritizing a slim profile, the manufacturer is betting that consumers value portability above the convenience of a native, built-in connector.

Technical Engineering and Performance

Despite its compact size, the Lexar Muse does not compromise on performance. The device utilizes high-density NAND stacking and a custom ultra-thin PCB architecture to achieve read speeds of up to 1,050MB/s and write speeds of 1,000MB/s. These metrics position the drive as a professional-grade tool capable of handling demanding tasks, such as recording 4K Apple ProRes video at 120fps, despite its minimalist footprint.

Market Positioning and Future Trends

The portable SSD market is increasingly crowded, with manufacturers constantly seeking unique selling points to differentiate their products. By targeting the 512GB and 1TB capacity segments, Lexar is aiming at content creators and mobile professionals who require high-speed data transfer without the bulk of traditional external drives. This trend suggests a broader industry shift toward 'invisible' technology that integrates seamlessly into slim laptop carry cases.

Conclusion

The Lexar Muse is a testament to current advancements in NAND storage density and PCB miniaturization. While the loss of a native USB-C port may be a point of contention for some power users, the device’s high-speed capabilities and extreme portability make it a compelling option for those who prioritize space-saving hardware in their creative workflows.
