Slow SSD disk in VMware ESXi

Slow SSD disk in VMware ESXi

Experiencing poor performance in VMware ESXi 6.5 with virtual machines on your SSD disk? Talking about 4-5 Mb/s in file transfers. I did and I fixed it by following tips on forums to disable the native AHCI driver. I have since upgraded to ESXi 6.7 and no longer have the issue.

Solution

Execute this command in the command line interface on your ESXi host:

esxcli system module set --enabled=false --module=vmw_ahci
