StarTech.com M2E4BTB3 Drive Enclosure - StarTech 4 Bay Thunderbolt 3 NVMe Enclosure, For M.2 NVMe SSD Drives, 1x DisplayPort Video and 2x TB3 Downstream Ports, 40Gbps, TAA 4 x 80mm PCIe M.2 M Key NVMe and/or AHCI SSD to Thunderbolt 3 enclosure Data tran

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).

M2E4BTB3 is backed by a 2-year StarTech.com warranty, with free lifetime North American based multilingual technical support.

- This M.2 enclosure does not provide full power delivery but will provide 15W of power, resulting in a slow charge to some laptops, such as MacBook Pro. When the dock is connected to your host laptop, a charging icon may appear on the screen. This is only sufficient to charge your laptop in sleep state, and charging will require an extended time period.
- 5K support can only be achieved using a Thunderbolt 3 5K monitor. DisplayPort 5K monitors will not work at 5K with this M.2 enclosure
- A 4K-capable display is required to achieve 4K resolution (4K is also known as 4K x 2K).
- Certain monitors may be limited to 4K at 30Hz when connecting through DisplayPort. These monitors include the following models: Dell P2715Q, Viewsonic VX2475Smhl-4K, Philips 288P6LJEB, LG 31MU97C-B, and Asus PB287Q (these models must be set to 4K at 30Hz).
- When connecting a display to one of the Thunderbolt 3 USB-C ports, a USB-C video adapter may be required, depending on the input of your display.
- Secondary Thunderbolt 3 port can also be used to connect USB 3.2 Gen 2 (10 Gbps) USB-Type C devices, such as USB 3.2 Gen 2 Hubs. Backwards compatible with USB 3.2 Gen 1 (5 Gbps), and USB 2.0.
- Not Compatible with SATA Based M.2 Drives.
