RTL9210C 固态硬盘盒SSD Enclosure

极致小体积 NVMe 转 USB 方案Ultra-compact NVMe-to-USB solution

基于 Realtek RTL9210C 单芯片 USB 3.2 Gen2 转 PCIe 3.0×2 桥接方案，我们为便携固态硬盘盒设计了一块极致小体积的 PCBA。正面 USB-A 直插，背面 M.2 2242/2230 插座，整板尺寸紧凑，可直接装入定制外壳成为高速移动存储。Built on the Realtek RTL9210C single-chip USB 3.2 Gen2 to PCIe 3.0×2 bridge, we designed an ultra-compact PCBA for portable SSD enclosures. USB-A plugs directly in on the front, while the M.2 2242/2230 slot sits on the back — ready to drop into a custom shell for high-speed mobile storage.

为什么做这么小Why so small

体积Size
极小Tiny

便携是第一优先级Portability first

USB-A 公头直插设计，省去转接线；PCBA 尺寸压缩到可放入口袋级外壳，真正做到即插即走。A USB-A male plug eliminates cables; the PCBA is squeezed into a pocket-sized shell for true plug-and-go.

兼容Compatible
即插即用Plug & play

主流 NVMe 协议支持Mainstream NVMe support

RTL9210C 原生支持 PCIe 3.0×2 与 NVMe 1.3，无需额外驱动即可在 Windows / macOS / Linux 下识别。RTL9210C supports PCIe 3.0×2 and NVMe 1.3 natively, recognized on Windows, macOS and Linux without extra drivers.

散热Thermal
低功耗Low power

低发热，长时稳定Low heat, long-term stable

RTL9210C 采用先进工艺，满载功耗低；PCB 预留散热过孔与外壳导热贴合位，连续读写不易掉速。RTL9210C's advanced process keeps full-load power low; thermal vias and shell contact pads help sustained reads/writes without throttling.
