Internally, the device uses an NVM Express (NVMe) SSD using quad-level cell (QLC) flash memory, providing lower performance than SSDs using triple-level cell (TLC) or 2-bit MLC flash.
The drive is based on Crucial's P1 internal SSD, but with modifications to its firmware to optimize it for external storage rather than for an operating system installation.
The internal SSD is connected to the external USB-C interface via an ASMedia 2362 bridge chip.
The drive was made available in capacities of 500 GB and 1 TB.
