This article covers StarTech.com 4ポート SuperSpeed USB3.0ハブ ブラック ST4300USB3.
Overview
The StarTech.com ST4300USB3 is a 4-port USB 3.0 hub that supports data transfer rates up to 5 Gbps. It is backward compatible with USB 2.0 and 1.1 devices, making it a versatile solution for expanding your desktop or laptop's connectivity. The hub can operate in bus-powered mode for basic peripherals, but it also includes an external power adapter that delivers up to 900 mA per port (2.9 A total) for power-hungry devices like external hard drives. This hub is a reliable choice for users who need to connect multiple USB-A devices simultaneously. Its compact footprint and driverless plug-and-play operation work across Windows, macOS, Linux, and Chrome OS. The model has been a staple in StarTech's lineup for years, earning a reputation for build quality and consistent performance.
Connectivity & Compatibility
The ST4300USB3 features four USB Type-A (female) ports and connects to a host via an included USB Type-A (male) cable. It supports USB 3.0 (5 Gbps) and is fully backward compatible with USB 2.0 (480 Mbps) and USB 1.1 (12 Mbps). When using the external power adapter (5V, 2.9A), each port can deliver up to 900 mA, which is sufficient for most external hard drives and USB-powered devices. In bus-powered mode, the hub draws power from the host's USB port, limiting the total available current to approximately 500 mA (USB 3.0 standard), so high-power devices may not work reliably without the adapter. Compatibility extends to all major operating systems without driver installation. However, note that the hub uses USB Type-A connectors; if your host only has USB-C ports, you'll need a USB-C to USB-A adapter or cable. The total bandwidth of 5 Gbps is shared among the four ports, so simultaneous use of multiple high-speed devices (e.g., two external SSDs) may result in lower throughput.
Product Info
The StarTech.com ST4300USB3 is a mid-range USB 3.0 hub priced around 3,000 JPY (~$30 USD). It comes with a 2-year warranty and lifetime free technical support from StarTech.com. The package includes the hub, a 45 cm USB 3.0 cable, an external power adapter, and a quick-start guide. This hub is positioned as a reliable, no-frills solution for users who prioritize stable power delivery over raw speed. While there are cheaper hubs available, the ST4300USB3 stands out for its clear per-port power specifications and the inclusion of a power adapter, ensuring compatibility with power-hungry peripherals. It is widely available on and directly from StarTech.com.
Best Use Cases
- Desktop users who need to bring USB ports to the front of their desk. Plugging in a mouse, keyboard, USB flash drive, and printer becomes much more convenient. The external power adapter ensures that even a 2.5-inch portable hard drive works without issues. 2. Laptop users with limited USB-A ports. If you have a thin-and-light laptop with only one or two USB-A ports, this hub instantly expands to four. It's also small enough to toss in a laptop bag. Just remember to bring the power adapter if you plan to connect high-power devices. 3. Office or educational environments where multiple peripherals are shared. The hub's rugged build and driverless compatibility make it easy to deploy across different computers. However, it's not ideal for transferring large files at full USB 3.0 speed to multiple devices simultaneously; for that, consider a USB 3.1 Gen 2 hub or a USB-C hub with higher bandwidth.
