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

Lexar has announced the Muse Ultra-Slim Portable SSD, joining other manufacturers in prioritizing compact form factors for portable storage devices. The drive will become available later this year in storage capacities of 512GB and 1TB, positioning itself as one of the thinnest options currently available on the market.

The device achieves its minimal profile through high-density NAND stacking and a custom ultra-thin PCB architecture. The drive measures 3.8mm at its thickest point in the center section, tapering down to just 1mm at the edges. Performance specifications indicate read speeds reaching 1,050MB/s and write speeds up to 1,000MB/s, capabilities that Lexar states are sufficient for recording 4K Apple ProRes video at up to 120 frames per second when used with compatible iPhones.

The design trade-off involves the elimination of a standard USB-C port. Instead, users must employ Lexar’s proprietary SnapLink cable, which connects via a pogo-pin connector on the drive’s side and uses magnetic attachment. This design choice introduces certain considerations: the magnetic connection strength is not publicly specified, and the cable could potentially disconnect if struck during file transfers. Additionally, users planning to record video through a smartphone must place the drive into an included magnetic sleeve for mounting, which adds considerable thickness to the overall setup during use.
