: USB 3.1 Gen 1 / USB 3.0 (Backward compatible with USB 2.0).

回顾 Phison PS2251-09 的技术生命周期，它既不是性能最强的战神，也不是稳定可靠的高端旗舰，但在消费级 USB 存储设备的发展史上，它绝对是一个绕不开的里程碑。

PS2251-09支持单通道闪存，最高可支持4个片选信号（4CE）。其主要升级在于官方加入了对于 的支持，这使得它能够搭配现今主流的3D TLC颗粒，在有限成本下实现高容量存储。

在具体的实测中，这款主控搭配 TLC 闪存颗粒时，读取速度普遍能够稳定在 120MB/s 至 200MB/s 之间，写入速度则在 40MB/s 到 100MB/s 左右。实际测试数据也验证了这一表现： phison ps225109
