Yeah, thats pretty similar to the bench I did in the enclosure. Though for time I limited the run to 3 instead of 5. There is an updated storage driver (IRST F6) to include PCIE support. (to enable Windows to recognize the drive during installation): M.2 storage devices are classified numerically based on performance. The higher the Class, the faster the overall performance:

Basically, if you are installing it into an external USB enclosure the fastest drive isn't worth much. The quality of the USB enclosure provides more of a boost than the fastest NVMe drive will. The SATA drives were all in a Startech USB M.2 SATA enclosure. The USB's are of course simply USBs. This enclosure is also the fastest of the bunch, but only by about 15-20MB/s pure sequential with large files. https://www.dell.com/support/article/us/en/19/sln312251/upgrading-storage-in-the-dell-precision-5820-7820-7920-tower-workstations?lang=enhttps://www.dell.com/support/article/us/en/04/sln312251/upgrading-storage-in-the-dell-precision-5820-7820-7920-tower-workstations?lang=en Full-custom loop builds: Meshify C (Full custom loop SLI) , Ncase M1(8700K + 1080Ti Full custom loop) Obsidian 900D (1950X + Quad 1080Ti)& Fractal Define C (1080 in SLI)

SABRENT M.2 SATA SSD to SATA 2.5 Enclosure Adapter, M.2

Please be aware that systems with Xeon W CPUs support two NVMe drives in the Flex Bays, whilst Core X Series CPUs support only one. I have been unsuccessful in getting support from Dell on installing this, so I am turning to the community for help.In addition my Parallels VM running Crystalmark. Even in a VM that is the fastest drive I have. The PCIe drive in the MBP is crazy fast. I think the randoms take a hit because of the VM acting as an interface layer. The drive you install (Samsung EVO, Intel 760p, etc....) has more impact on the speed than the enclosure does. M3X3 screw(most computers include these. These secure the Y1WJX M.2 drive carrier, or a 2.5" drive into 745TM) I didn't want to start a new thread for this as I had a few questions more or less related to this topic.
