Description and Notes
KIOXIA’s BG4 M.2 NVMe SSD drive is an inexpensive NVMe SSD commonly used in laptops.
It is an inexpensive SSD that doesn’t include any DRAM, and relies on a technology called NVMe Host Memory Buffer (HMB) that essentially moves NVMe cache to the system’s RAM.
Using my disk-benchmark.sh script, I got the following performance numbers on the Pi CM4:

|iozone 1M random read||170 MB/s|
|iozone 1M random write||157 MB/s|
|iozone 4K random read||29.71 MB/s|
|iozone 4K random write||54.50 MB/s|
