## Description

GRAUGEAR

## Features

- 【40Gbps Ultra High Speed】USB 4.0 ASM2464PD chipset supports USB-C(USB Type-C) connection and data transmission speed up to PCIe 4.0 x4 40Gbps for steady and efficient data transfer. Compatible with Thunderbolt 4/3 and backward compatible with USB 3.2/3.1/3.0/2.0 at respective speed limits (Please be sure to use USB 4.0 or Thunderbolt 4 interface and upgrade the OS build and NVM FW version to the lastest version to achieve 40Gbps transfer speed. Backward compatibility will limit the speed, and the device might not be recognized)
- 【Efficient Heat Dissipation】The combination of active heat disspation with built-in cooling fan and passive heat disspation with copper heatpipe and aluminum heatsink helps dissipating the heat generated by M.2 SSD. Effectively protect your SSD from overheating and keep high transfer rate
- 【Optimal Cooling】Highly optimised 30mm fan with low-noise adaptor for ultra-quiet operation would find the balance between the cooling performance and noise level. This cooling fan reduces the heat of M.2 SSD by 60%. Better heat dissipation, less strain on his M.2 SSD when working
- 【Direct Touch Heatpipes】Dual copper heat pipes provides better cooling performance by using DTH(Direct Touch Heatpipes) technology. Its flat machined surface touches the SSD evenly and conducts heat extremely fast
- 【Stability and Safety】NVMe PCIe reader adopts an advanced ASM2464PD controller that built with short-circuit, over-current and multi-protection to ensure safety for your SSD and valuable data

## Questions & Answers

**Q: Is Thunderbolt the same as USB4?**
A: Both can drive dual 4K displays, transfers data at 40Gbps, and provide power to charge a laptop. But USB4 has lower minimum specs, and makers can choose not to implement all the features to minimize costs.

**Q: Why does my hard drive enclosure's performance differ from what's advertised?**
A: Speed test results can vary based on factors like software, hardware, and operating environment. For optimal performance, use a USB4 or Thunderbolt 4 connection.

**Q: Why is my hard drive enclosure unreliable on Windows?**
A: Windows system compatibility can vary due to platform differences and infrequent firmware updates. To improve reliability, use a Windows system with an Intel 12th generation or newer CPU, or an AMD Ryzen 12th generation or newer CPU.

**Q: How can I improve writing speed on Windows devices?**
A: Because speed test performance can vary due to different software, environments, and hardware, it is recommended to use a USB4 or Thunderbolt 4 interface to get the best speed performance.

**Q: How can I prevent an increase in unsafe hard drive shutdowns?**
A: The enclosure is connected to the PCIe interface of the device and cannot be directly removed like ordinary USB devices, please shut down your computer and remove the enclosure to avoid an increase in the number of unsafe hard disk shutdowns.
