Despite being an entry-level to mainstream PCIe 3.0 drive, the EXCERIA G2 drive from KIOXIA does incorporate BiCS TLC Flash, which means that we are getting much better performance versus the QLC variants, but also increased endurance, the TBW being set at 400 TB. On this particular drive, we noted the most notable performance drop after about 30GB have been written continuously to the drive, which tells us that the pseudo-SLC cache is quite small.
