The Phison PS2251-19 is a high-performance, single-chip USB 3.2 Gen 1-to-Flash controller supporting 32GB to 512GB capacities for Type A and Type C drives. It offers sequential speeds up to 220 MB/s read and 100 MB/s write, serving as a versatile solution for consumer pendrives. For more details, visit Phison.
One of the biggest challenges with USB 3.0 drives is heat and power consumption. The PS2319 features intelligent power saving modes and thermal throttling mechanisms. This prevents the drive from overheating during sustained writes, a common issue with cheaper controllers, and ensures compatibility with low-power ports (like those on ultrabooks or hubs).

The controller is designed for COB packaging. This allows manufacturers to solder the controller and the NAND flash directly onto the printed circuit board and cover it with a single black epoxy blob. This reduces manufacturing costs and creates smaller, more durable form factors (like the "nano" receivers often used for wireless mouse dongles or car audio drives).
While real-world speeds depend heavily on the NAND flash used, the PS2251-19 typically delivers:
