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,
