UFS (Universal Flash Storage) is a high-speed, low-power flash storage interface designed for mobile and embedded applications. Unlike eMMC, which uses a half-duplex parallel interface, UFS uses a full-duplex serial interface (MIPI M-PHY + UniPro stack), enabling simultaneous read and write operations.

The performance difference is significant. UFS 2.1 delivers up to 1200MB/s sequential read. UFS 3.1 pushes to 2100MB/s. UFS 4.0 reaches 4200MB/s — roughly double what the best eMMC can achieve. That matters for camera burst buffers, OS boot times, and application load on compute-intensive embedded platforms.

UFS is not pin-compatible with eMMC or SD. The physical package (typically BGA) and the electrical interface are completely different. If you're migrating from eMMC to UFS, the carrier board needs a redesign. For automotive applications, look for AEC-Q100 qualified devices — standard commercial UFS parts are not rated for the temperature range or long-term reliability requirements of automotive electronics.

TRX sources UFS devices from Samsung, Micron, SK Hynix, and Kioxia through authorised distribution, with stock available across Johannesburg, Cape Town, Durban, and Pretoria. No minimum order.
