The Toshiba KBG30ZMT128G is a compact (M.2 22x42) NVMe class SSD. We found the 128 GB drive's performance to be subpar in our independent testing in 2018.

Notebookcheck says:

... The Toshiba KBG30ZMT128G, a rather unconventional M.2 2242-sized drive, requires an adapter to span the full length of the M.2 2280 slot. It's also not a very impressive drive in context with its NVMe peers - Lenovo Legion Y530 Laptop Review, 2018

... at just 116 MB/s sequential write the performance turned out to be pretty poor despite NVMe support. Sequential read speeds were as fast as expected, and application launch times were decently fast. We suspect the SSD’s self-encryption (OPAL 2.0) to be mainly responsible for the poor write performance - Lenovo Thinkpad E580 Laptop Review, 2018
