I had to (unexpectedly) upgrade my lab PC because of a MB malfunction. It was over 3 years old so most of the peripherals (except disks) were also replaced/ will be replaced soon.
Since the financial damage is done, I now want to consider a better solution for my hard disks. Remembering my lab work and performance, the troubling part has always been the IOPS when I turn on multiple VMs, I ended up having 2 SATA disks to address that. I also tried external disks (SSD with USB 3 interface) - the results also did not please me, I could only turn on 2 VMs in parallel with less than acceptable performance.
I want to know your thoughts and chosen approaches for this. I am wondering if there's any external chassis you can recommend (or perhaps a PCI card) which I can go for when I need to increase the number of VMs or storage.
Final Note, I am using maximum 10 VMs at a time.
Thank you in advance
