Capacity Limitation: Compatible with 4TB, 6TB, and larger capacity 2.5 -inch U. 2 NVMe SSDs without any restrictions on storage size ^^
Wide Compatibility: Plug and play with no driver required. Compatible with Windows 11/10/8, Linux, and macOS, and backward compatible with PCIe 3.0 / 2.0 / 1.0. New U. 2 SSDs need to be initialized and formatted ^^
