Quote: "The SSD is more than fast enought for my needs. Funny thing is that it’s even faster under Windows (3.5 GBps read and 3.3 GBps write)." Also OP is showing ~2.5 Gbps in an image.

Funny thing, I run my Macs in virtual machines (VMWare), and the speed is identical to Windows (host OS), while all other OS'es (Linux / BSD / other Windows') show slower speed. I wonder why.

I thought you could only run Mac VMs on a Mac host. Has that changed, or did you hack VMware somehow?

Our automation group has a couple of maxed out trash cans just for Mac VMs. The IT department probably can't wait to replace them with the new rackmounts.

As other said it, there is unlocker for VMWare which allows you to have Mac OS as option when creating a new virtual machine.

As for hacking VMWare I got my hands on a official Mountain Lion image years ago, directly from Apple, which I used to copy/upgrade into new VM each time a new Mac OS was released. I have lying around cca 15 VM's with different flavors of Mac OS each, all tests for various projects for my clients.

Legally you can only run them on Mac hardware, even if it's a windows/linux OS.

As for technically, it's possible. I believe you either have to edit some file or run a patcher to get it to run MacOS though.

look for unlocker on github

Screenshot shows 3 GBps for both read and write under Windows. Windows has 3.5/3.3.

Correct. Also for curiosity I did a test on my host and Mac VM. Program reported on both Windows and Mac VM same speed of ~500 MB/s (which translates into 4.8 Gbps for OP style). On Linux I got ~450 MB/s. I used Total Commander in all cases (my normal file manager) and used my Witcher 3 .iso file as test (66 GB in size).

I think you are misreading/misunderstanding the performance of modern NVMe SSDs.

SATA based SSDs which it sounds like you have, top out at around 550MByte/sec.

However a PCIE 3.0 NVME can easily achieve 3500 MByte/sec throughput. That's saturating the PCIE 3.0 x4 link. PCIE 4.0 based SSDs are even faster, with advertised 5000MByte/sec throughput (but in testing may top out slightly slower than that)

Yes, modern SSDs are stupid fast.

Aye, it's SATA. PC is from 2013, old badly, planning this year to make a new one. But it covered me in past 7 years quite nicely. I made a quick math with my wife when she complained why I need a new one since this one is still good. Calculated that in past 7 years she paid 20% more in her cell phone subscription then me in buying/upgrading the PC all these years. And it was the work horse with at least 10 hours daily running, average of 16 and plenty of times stayed on for days.
