Some Thunderbolt 3 ports support a 2-lane PCI Express configuration (PCIe x2), and some support a 4-lane PCI Express implementation (PCIe x4). Performance will depend on the specific workload. The maximum throughput of the drive be reduced in some scenarios on systems with a PCIe x2 implementation. In our testing, the maximum R/W results on an x2 system were ~1400MB/s R and 1200MB/s W.
Will the drive perform differently based on the host system PCIe specifications?Last Update: August 13th, 2020
