[Unopened/Unused] UGREEN USB4® 40Gbps M.2 SSD External Enclosure M.2 SSD Case Thunderbolt 3/4 PCIe 4.0x4 Compatible NVMe SSD Case 2230 2242 2260 2280 (M-Key M&B Key) SSD Compatible USB C Cable Included ・Hardware Interface: USB-C ・Brand: UGREEN ・Color: Silver ・Product Dimensions: 12.2 length x 6.6 width x 2.7 height cm ・Hardware Platform: Linux, Mac OS, Windows [Ultra-High Speed Next-Generation Standard USB4 Compatible] This M.2 NVMe SSD case supports USB4, enabling high-speed data transfer at 40Gbps (theoretical value). The measured maximum read/write speed reaches 3600MB/s. [Please Note] With this product, the read/write speed on M2 chip MacBooks and those with SSD capacities of 256GB or less will be slower, with a maximum speed of approximately 20Gbps. To achieve speeds of 40Gbps, a Thunderbolt 3 or USB4 equivalent port is required. [Rapid Cooling, Powerful Heat Dissipation] Achieves quiet and high-speed transfer with a triple heat dissipation design. High thermal conductivity aluminum material and dual fin panel design, along with a built-in thermal conductive sheet, expand the heat dissipation area by 90%, quickly dissipating heat from the HDD. ※Everything in the photos is included. #UGREEN #Hard Drive Accessories #Enclosure #HaruSHOP SOC IT i7-3-2
