In 2023, driven by the replacement of the old and new laptops of the new generation, the penetration rate of USB4 and Thunderbolt 3/4 (hereinafter referred to as Thunderbolt 3/4) has increased significantly, from entry-level all-round laptops and ultrabooks of four or five thousand yuan to tens of thousands of yuan of e-sports flagships and workstations, USB4 and Thunderbolt 3/4 high-speed interfaces have high visibility, and ordinary consumers can access the high-speed interfaces that were unattainable a few years ago.
In contrast, the corresponding USB4 and Thunderbolt 3/4 accessories market has also ushered in a big wave of enthusiasm, among which the most popular is the USB4 ultra-fast SSD enclosure. In the past Double 11, Greenlink, which won the TOP1 in the 2023 JD hard disk enclosure category, has newly released a new USB4 ultra-high-speed solid state drive enclosure with a variety of heat dissipation technologies, which refines the already rich product line of Greenlink hard disk enclosure and brings consumers a low-temperature, stable and high-speed external storage experience.
The detailed model of the USB4 M.2 NVMe SSD enclosure is CM642, the three measurements of the whole machine are 120*48*19mm, the body is made of thickened CNC aluminum alloy, the sturdy metal shell has the characteristics of drop-resistant, wear-resistant and fast heat dissipation, the nickel-plated USB-C interface provides 5000 times of plugging and unplugging durability, and there is a white LED indicator next to the "UGREEN" logo on the surface of the body, which is solid to indicate standby/hibernation, flashing to read and write data, and clearly know the current working status of the SSD.
Old-style SSD enclosures are limited by the 5Gbps bandwidth of the device, and the read and write speeds are generally only hundreds of MB/s, which cannot give full play to the real performance of SSDs, and cannot be separated from USB flash drives. The Greenlink USB4 M.2 NVMe SSD enclosure is an ultra-fast external hard drive enclosure that uses a universal USB-C physical interface and supports the USB4 ultra-fast protocol to connect with devices at speeds up to 40Gbps.
According to the CrystalDiskMark test provided by Greenlink, the sequential read and write speeds of Greenlink's USB4 M.2 NVMe SSD enclosure reach 3658MB/s and 2978MB/s respectively, and about 3GB files can be transferred in 1 second, and a large number of file copies can be completed in an instant.
The price of large-capacity SSDs on the market is becoming more and more affordable, 4TB has dropped to more than 1,000 yuan, and the Greenlink USB4 M.2 NVMe SSD enclosure supports 4TB ultra-large capacity SSD, which can be loaded with about 1.39 million high-definition photos, 130,000 lossless music, and 2,700 ultra-HD movies.
The Greenlink USB4 M.2 NVMe SSD enclosure is also equipped with a silicone protective case, which is wrapped around it to cushion and absorb energy, and is resistant to drops and scratches, providing all-round protection for the SSD and hard disk enclosure. Built-in surge protection, short circuit protection, and ESD protection protect data from the inside out.
As we all know, in the process of reading and writing SSDs, the main control and flash memory particles will generate considerable heat, and high temperatures will limit the performance of SSDs and have an impact on the lifespan. As an ultra-high-speed storage device, the Greenlink USB4 M.2 NVMe SSD enclosure has been systematically reconstructed in terms of heat dissipation to ensure stable SSD performance.
The Greenlink USB4 M.2 NVMe SSD enclosure uses two thermal pads, the heat dissipation stickers precisely fit the core heating area, the sandwich wrap method is the main control, and the particles quickly dissipate heat, and the top cover is composed of a silver flat cover plate and a copper-colored hollow groove plate, and the heat dissipation area is 150% larger than that of traditional flat products In addition to passive heat dissipation, the drive's built-in turbofan actively dissipates heat, drawing cold air from the outside to take away the internal heat and then dissipating it from the heat vents, reducing the temperature of the drive by another 17°C.
The top cover of the USB4 M.2 NVMe SSD case is installed by pressing the screws to close the lid, which makes the thermal pad in better contact with the SSD than the common push-pull closure method. Inside, there is an M-Key M.2 slot, a high-speed SSD that supports the NVMe protocol, and a total of four fixed holes, which are assembled by Phillips screws, and can be installed with the most common 2280 specifications, as well as the 2260 / 2242 / 2230 "short strip".
In terms of compatibility, it is suitable for macOS, Windows, Linux, desktops, laptops, Android phones, iPhone 15 series, iPad and other devices, and the device interface specifications support USB4, Thunderbolt 4, Thunderbolt 3, USB 3.2 / 3.1 / 3.0 / 2.0.
Summary of the charging head network
The USB4 M.2 NVMe SSD enclosure uses USB4 high-speed interface, supports the NVMe protocol M.2 SSD, is compatible with a variety of lengths, and can be installed up to 4TB capacity. Greenlink uses four means: aluminum alloy metal body rapid heat conduction, dual thermal pad sandwich clamping core heating area, hollow cover plate to enhance convection passive heat dissipation, and turbofan active heat dissipation, to quickly take away the heat of the SSD, so that the performance is durable and stable, the test data speed can reach 3658MB/s, which can run the performance limit of the PCIe 3.0 SSD, and can also make the PCIe 4.0 SSD play better.
The packaging of the Greenlink USB4 M.2 NVMe SSD box contains the SSD case body, silicone protective case, thermally conductive silicone pad, screwdriver, CtoC USB4 data cable, and AtoC data cable.
