VANGREE 80Gbps M.2 NVMe SSD Enclosure with Cooling Fan — Thunderbolt 5/4/3 & USB4 V2.0 Compatible, Backward USB 3.2/3.1/3.0/2.0, Supports B+M M-Key NVMe 2230–2280 up to 8TB — Works with Mac M4 Pro

High-speed external enclosure delivering up to 80Gbps when used with Thunderbolt 5 — also backwards compatible with Thunderbolt 4 and 3, USB4 V2.0, and older USB standards (USB 3.2 / 3.1 / 3.0 / 2.0). Important: the full 80Gbps rate requires cables and hosts that support Thunderbolt 5 or greater. This enclosure is not compatible with M.2 NVMe key-to-PCIe adapter cards for direct PCIe device connections. Storage compatibility: accepts NVMe M.2 SSDs in 2230, 2242, 2260 and 2280 form factors, supporting up to 8TB of capacity and B+M M-Key configurations. Note: it does not support M.2 (B-KEY) or (M&B)-KEY SATA NGFF SSDs. Cooling system: a built-in fan helps keep temperatures down — it kicks in automatically when the internal temperature exceeds 40°C and can be forced on manually by holding the fan switch for 2 seconds. Ideal for high-performance workflows and compatible systems including Mac M4 Pro.
