Compatible with a wide range of NVMe SSD sizes and operating systems, it features a powerful ASM2426PD chip for real-time SSD health monitoring and robust protection. Compact and portable, this enclosure is designed for professionals demanding speed, reliability, and style on the go.

## Description

Product Description UGREEN USB 4.0 M.2 NVMe SSD Enclosure (40Gbps) 40Gbps nvme enclosure 47% more area compared to a 10Gbps Enclosure, provides more robust protection and better dissipation Thanks to the thermal pad, heat generated by the SSD is quickly transferred to the aluminum case Quickly remove the huge heat generated by SSD out of the system with PWM Turbofan. Why can't my computer recognize my SSD? 1. Verify that the product, hard drive, and computer are properly connected and that the hard drive is correctly installed. 2. A new hard drive must be partitioned and formatted for the first time; otherwise, the computer will not recognize the drive letter. 3. Verify that the system supports large-capacity hard drives. 32-bit Windows XP does not support hard drives larger than 2TB. 4. Verify that the hard drive format matches the system's supported format. If not, format the hard drive to a supported format: Windows supports NTFS/exFAT/FAT32, while Linux and macOS support exFAT. 5. Test by connecting the product to another USB port on the computer. For a desktop computer, connect the product to the USB port on the back of the unit. 6. Replace the product cable and test again. 7. Replace the hard drive and test again.8. Test again by connecting the product and hard drive to another computer. How to improve the transfer rate on Windows when used with Thunderbolt 4/USB4 ports? 1. The NVM and PD versions of the operating system are relatively old. Please try to update the operating system to the latest version. 2. For Windows users, please select Better performance and enable write cache: Go to Disk Management > Select Properties > Click Policies > Choose Better performance and enable write caching on the device. Why does the enclosure heat up during using? The enclosure uses an aluminum alloy shell with a PWM turbo cooling fan to help transfer heat from the hard drive to the outside to prevent the internal temperature from heating up. The maximum operating temperature of the enclosure is below 60°C, which is a safe range. Why does the read and write speed of the enclosure decrease after running for a while? The maximum transfer rate of the enclosure can reach 40Gbps. High-speed transfer makes the hard disk heat up. If the temperature is too high, the controller of the enclosure and SSD may activate thermal throttling protection, automatically reducing the transfer speed to protect the hardware from damage.

Review: Works amazingly - when setup correctly! - Summary: Looks good, feels good, performs amazing - IF YOU ENABLE WRITE CACHING! This SSD enclosure is amazing, its really fast (not quite the 40Gbps advertised limit - but it is expected not to hit this as this is a theoretical raw transfer rate that is also bidirectional), it also had a very good build quality, and feels very premium. To all those reading the comments and feeling torn due to the reviews that report slow write speeds - fear not! I also had my doubts; when testing the product for the first time (with a Kioxia gen 4 drive) I had the same issues (see picture 1). After doing a little digging I found that under Device Manager > Disk Drives > (NVME Drive in your enclosure) > Properties > Policies: "Enable write caching on this device" had defaulted to off. After turning this on (see picture 2), and testing again, the expected speeds instantly shot up to expected speeds (see pictures 3 and 4). Note: Enabling write caching this way is specific to Windows, I am unsure how this setting defaults on Apple devices, but I am confident that a synonymous setting exists.
Review: So far so good. It works well on my Mac Mini M4 - I like, it feels very well made and is a decent weight The fan works and is quiet Works with my Time Machine The included screw and attachment process - much preferred to a tool less design. Looks good - not an issue for me but it does I don’t like, the heat. This is hot when in us and when idle. This may be down to the thermal pad, not doing a job - It is TOO THIN. Currently I have no other pads but have ordered a pack - update to follow Currently NOT attached 24/7 as I don’t wish to consistently run it hot Long term, I may get a couple of stainless steel blocks 80x30x30 and use those as heat soaks Update, Had this a week or so now, running cooler than it originally was, I suspect that’s due to the whole system now registered together. It does run faster when connected to my hub, a bit strange but not significant.

## Features

- Transfers 1GB of Files in 0.3s: The M2 SSD enclosure features a USB 4.0 Type C port with data transfer rates up to 40Gbps. Compatible with the Thunderbolt 3/4 interface and supports UASP & TRIM protocols. The actual tested transmission rate reaches 3656.3 Mb/s.

### ⭐⭐⭐⭐ Good external memory enclosure
*by D***N on 29 December 2024*

Operates well with very fast NVMEs. Runs warm when idling and hot when working. The fan is quiet, almost silent. The rubber enclosure protector is not necessary unless to limit vibration, which I haven't experienced. It impedes air intake for the fan and reduces heat dissipation. Works fine without it.
