Very Slow SSD Benchmarks on VM

[Hexenhammer]

Hello,

I have windows 11 installed on Samsung 850 PRO SATA SSD [these are old MLC drives that easy benchmark 540Mb/s read writes]

JMB585 in Gen 3.0 x1 slot with just this SSD, IOMMU, no VDISKS, its installed directly to SSD [I can boot without VM from bios too]

 

I got 223MB/s Reads, 214MB/s Writes

Samsung programs also says AHCI disabled

 

What am i doing wrong here?

 

P.S. I installed a driver pack that comes on Virtio 229-1 ISO file

 

Thanks
