Performance of NVME SSD Disk with VMware Workstation 12 Pro

This post was originally published on this site



Recently we installed some of Samsungs new NVME SSD Disks (PCIE M2) and there is quite a difference in the performace of that SSD on the Win 7 PC directly and within a Win 7 virtual machine on that very same PC…



The AS SSD Benchamrk gives following results:


Seq Read, 10 GB on PC directly:   2611 MB/s

Seq Write, 10 GB on PC directly:   1620 MB/s


Seq Read, 10 GB in VM:                1446 MB/s

Seq Write, 10 GB in VM:                  778 MB/s


The VM uses the SSD via SCSI.


Since it is the very first time I installed a VM I wonder if that loss of disk performance is to be expected, or should the VM perform better?




If the performance for read / write on the PC directly is set as 100% what performance could be expected within the VM?
80% or maybe just 60%? Or did I do something wrong?


If the disk performance in the VM can be improved, how so?













Thanks in advance,
