Upgrading my MacBook Pro (Retina, 13-inch, Early 2015) with 500GB flash storage.
Decided to use the Adata XPG SX8200 Pro 2TB 3D NAND NVMe Gen3x4 PCIe M.2 2280 for my SSD upgrade. Purchased from Fuwell @ SGD359 on 28 December 2019.
The Adata SX8200 Pro 2TB connected to the NVMe convert adapter is detected by the system.
Due to the PCIe 2.0 x4 interface limitation (Retina MacBook Pro 13-inch, Early 2015), we will not be able to achieve the XPG SX8200 Pro advertised sequential read/write speed of 3500/3000 MB/s.
Did you install something else?? Or only update Catalina? My makbook is a MacBook air 13” early 2015
