Real-World Performance Analysis

• Read speeds are respectable: 100-130 MB/s is fine for transferring movies or ISO files.
• Write speeds are mediocre to poor: While initial burst writes may hit 40 MB/s, sustained writing (over 1GB) will often drop to 8-15 MB/s due to TLC/QLC direct writing (no pseudo-SLC cache).
• USB 2.0 Mode: If plugged into a USB 2.0 port, expect ~35 MB/s read and ~12 MB/s write.

The Phison PS2251-19 is a single-chip USB Flash Drive (UFD) controller. It serves as the bridge between the NAND Flash memory (where your data is stored) and the USB interface (how your computer talks to the drive). Phison PS2251-19 Go to product viewer dialog for this item
