Note that PCIe Gen3 SSDs are needed to get the best performance with M1 due to RK3568's PCIe limitation being Gen3 two lanes only.
As such every Gen2 x4 SSD will only be able to establish a Gen2 x2 connection halfing its sequential transfer speeds as well as harming random I/O performance.
Actual Base Clock Speed : PCIe 3.0 (Gen3) = 8.0GHz, PCIe 2.0 (Gen2) = 5.0GHz .
Ideal Data Rate per lane : PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s
PCIe 2.0 uses an 8b/10b encoding scheme
PCIe 3.0 uses an 128b/130b encoding scheme for faster data transfer rate
NVMe benchmark test
Please be aware of performing a storage benchmark could cause a data loss on a target storage, one must make sure data in the storage is backed up before start.
Installing performance test packages
sudo apt install fio iozone3
