** Sabrent Rocket PCIe 4.0 NVMe SSD in Top PCIe 4.0 M.2 Slot **
Thanks to the recent NewEgg FantasTECH sales event, I purchased a
Sabrent Rocket 1TB PCIe 4.0 NVMe SSD at an attractive price. Because the Gigabyte B550 in combination with AMD Ryzen 7 3700X supports PCIe 4.0, the natural destination for that SSD is the B550 Vision D. The
Z490 Vision D, however, will be able to support PCIe 4.0 NVMe SSDs with new Rocket Lake processors.
After moving the previous Silicon Power 512GB SSD to the bottom slot and installing the Sabrent Rocket in the top slot, I needed to perform a CMOS Reset and configure BIOS parameters. After that, macOS booted up just fine.
The Sabrent Rocket 1TB PCIe 4.0 drive is performing quite well at over
4000 MB/s in both read and write. I can happily state that macOS supports this drive on a PCIe 4.0 bus.
NOTE: When we populate the lower M.2 slot with an NVMe SSDs, we lose the bottom PCIe X4 slot.
