I know it means more testing having to run the tests with ext4 and xfs this would kind of give best and worse cases. Yes excess IO not well ordered IO can completely flip your results because the SSD performance can be stalling as it attempt to move data from 1 or 2 bits to 3-4 bits per cell for long term storage that are only happening because the writes to drive were not well ordered. Lot of your M.2 items are using multi bit per cell flash 3-4 per cell for long term storage and 1 or 2 bit per cell for fast writes. am sorry Michael Larabel we are getting more and more to the point that the fault that the XFS developer detailed in 2012 at LCA ( )with ext4 with excess IO and not well ordered IO will be messing with your results. Phoronix: Seagate FireCuda 520 PCIe Gen4 NVMe SSD Linux Performanceįor those that have been considering the Seagate FireCuda 520 as a PCI Express 4.0 NVMe solid-state drive, here are some benchmarks under Ubuntu Linux with this ZP500GM3A002 drive.
