Hello, I have a macbook pro 13 2017 no Touch Bar and I'm about to replace the SSD. The MBP has a PCIe 3.0 x4 bus, the drive I chose was a lexar NM620 1 tb PCIe 3.0. 3300MB/s read, 3000MB/s write. My question is if I chose the Lexar nm710 PCIe 4.0 read 5000 mb/s, write 4500 mb/s or Lexar NM800 pro PCIe 4.0 read 7500mb/s, write 6300 mb/s, what speeds would the speed of PCIe 4.0 drives be reduced to ?? Is it better to buy Leca NM630 PCI 3.0?? Thank you for your help
