4-Drive PCIe M.2 Enclosure | Thunderbolt™ 3 | 72W EPS Power Supply & 2.3 ft (70 cm) Thunderbolt 3 Cable IncludedThis 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 3The 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 DriveA 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 CertifiedThis 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 FlexibilityThe 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).M2E4BTB3 is backed by a 2-year StarTech.com warranty, with free lifetime North American based multilingual technical support.Notes:• This device is not compatible with SATA based (B-Keyed or M+B Keyed) M.2 solid state drives.• This device does not support Thunderbolt 2 or Thunderbolt 1 host devices using interface adapters.• This device only supports 80mm M.2 SSDs.• Connected downstream devices share bandwidth with connected SSDs and may reduce overall data transfer performance when connected.• Apple Mac computers with M1 processors can only support one external display connected through the SSD enclosure. However, Apple Mac computers with Intel or M1 Max / Pro processors can support dual external displays connected through the SSD enclosure.The StarTech.com Advantage
