4 x 80mm PCIe M.2 M-Key NVMe and/or AHCI SSD to Thunderbolt 3 enclosure - Data transfer speeds up to 40Gbps - Downstream TB3 port - DisplayPort output wesolutions up to 4K 60Hz - Thunderbolt 3 Certified - 72W EPS power supply - 3.3ft TB3 cable General Information Manufacturer: StarTech.com Manufacturer Part Number: M2E4BTB3 Brand Name: StarTech.com Product Name: 4 Bay NVMe TB3 SSD Enclosure Marketing Information: This Thunderbolt 3 to 4x M.2 PCIe SSD enclosure enables you to turn four M-Key PCI-Express based M.2 NVMe or AHCI solid state drives (SSDs) into a high-performance external storage solution. The SSD enclosure is self-powered with an included 72W EPS power supply that powers the enclosure, the connected drives, and provides up to 15W of power to any downstream Thunderbolt 3 devices. A 2.3 ft. (70 cm) Thunderbolt 3 Certified host cable is also included, to connect the enclosure to your computer. High Performance M.2 Storage via 40Gbps Thunderbolt 3 The enclosure is compatible with 80mm M.2 PCIe based (M-Key) single/double-sided SSDs. Create an external storage solution that utilizes the high-performance bandwidth available to your Thunderbolt 3 port, providing combined data transfer speeds of up to 40Gbps for up to four drives. The vented metal enclosure features thermal pads and a cooling fan to ensure your SSDs are operating at optimal temperatures. Dedicated 8Gbps Throughput for Each Individual Drive A single 8 Gbps PCIe lane is dedicated to each connected drive. This ensures consistent read/write performance across the entire enclosure, regardless of individual drive activity. The enclosure also supports software RAID with storage management systems like Storage Spaces (Microsoft), RAID Assistant (macOS), or mdraid/mdadm (Linux). The support for software RAID, combined with exceptional drive performance, makes this the ideal enclosure for creative professionals working with large files such as high-resolution graphics, video, and CAD files. Thunderbolt Certified This enclosure is Thunderbolt Certified to ensure an optimal user experience and compatibility when connected to a Thunderbolt 3 host device, such as a MacBook Pro 16, 13, Air, Lenovo ThinkPad X1 Carbon / T Series, Dell XPS / Latitude / Precision or HP EliteBook. The external drive enclosure is also forward compatible with Thunderbolt 4 devices (at Thunderbolt 3 performance). Additional Ports for Workspace Flexibility The enclosure features a DisplayPort output port, enabling you to connect a DisplayPort monitor to your computer through the Thunderbolt 3 enclosure, with resolutions up to 4K 60Hz. The enclosure also features a downstream Thunderbolt 3 port for daisy chaining an additional TB3 device or connect an additional TB3 compatible display (up to 5K 60Hz).
