ACASIS 80Gbps M.2 NVMe SSD enclosure with cooling fan, compatible with Thunderbolt 5/USB4 V2.0. Supports MacBook Pro M4/M4 Pro and M4 Max, as well as Mac mini M4.

["1. Next-generation chip: JHL9480: Powered by the advanced JHL9480 chip, this enclosure offers high performance, stability, and future-proof features. It ensures fast data transfer and compatibility with various Thunderbolt interfaces. We are equipped with two chips, JHL9480 and RTL9210, ensuring fast data transfer and compatibility with various Thunderbolt interfaces. Additionally, it is backward compatible with Thunderbolt 4/3, USB4 V1.0, USB3.2/3.1/3.0. 2. Read and write speeds of up to 6000 MB/s: Achieve lightning-fast read and write speeds of up to 6000 MB/s, perfect for content creators, gamers, IT professionals, and developers needing fast, reliable storage for large files, data-intensive tasks, and high-speed transfers. ⚠️ To reach speeds over 3000 MB/s, use an SSD with PCIe 4.0 x4 and NVMe 1.4 or higher, avoiding M.2 PCIe 5.0. 3. Adjustable cooling fan for optimal performance: The built-in cooling fan activates automatically at 55°C and stops at 40°C to maintain stable performance and extend the SSD's lifespan. It also supports manual control – Hold the switch for 1 second to force the fan to turn on. Once turned off, the system will resume automatic temperature detection. 4. Universal compatibility: Compatible with Thunderbolt 5 and USB4 V2.0 for maximum speeds, MacBook Pro M4/M4 Pro and M4 Max, Mac Mini M4, and backward compatible with Thunderbolt 4/3, USB4 V1.0, as well as older USB standards like 3.2, 3.1, and 3.0, ensuring broad device compatibility. ⚠️ Not compatible with an M.2 NVMe key to PCIe adapter for connecting PCIe devices. The device speed is 80Gbps. To increase performance speed, it is recommended to set the hamster interface to 80Gbps. 5. Plug-and-Play, driverless: No drivers needed – simply plug in and start using it. The easy and user-friendly installation allows you to focus on your tasks without delays. 6. Compatibility notes for Thunderbolt 3 users: Thunderbolt 3 systems may not fully support Thunderbolt 5 and may default to USB speeds, limiting performance to 10 Gbps. For Thunderbolt 3 users, we recommend using a Thunderbolt 3/4 SSD enclosure instead of this Thunderbolt 5 model, as it offers faster speeds than a USB connection. 7. For smartphones/tablets: A 1TB SSD is recommended – Works seamlessly without additional power supply. ⚠️ 2TB/4TB SSDs – Due to higher power requirements, an external power supply enclosure may be necessary. Universal computer support: ✔️ All capacities (1TB/2TB/4TB/8TB) deliver optimal performance."]
