|I just bought a new laptop for the sole purpose of doing labs at home to help advance my professional life. I bought a Lenovo Y70 laptop. When I run about 8-9 VMs, everything is fast except the hard drive. The VMs will slow down to a crawl and I check the resources and the hard drive is 100%. |
So, as I lied awake sleepless last night, I got to thinking, maybe a USB 3.0 hard drive would be faster, and having a dedicated HD for the VMs might be faster than using my OS drive.
I just copied them over. Preliminary results, it seems to be about the same speed. Not faster or slower.
The specs of my laptop says my SSHD is 6 Gb/s. But I'm sure when I'm running VMs, they're running from the spindle hard drive and not SSD, so I'm sure that 6 Gb/s is slowed down by the slow hard drive.
When I copied my VMs from the laptop to the HD, it was averaging about 70 MB/s. But when checking resources, I think what was limiting it to 70 MB/s was the USB's internal hard drive, not the USB port.
I was wondering then maybe getting a USB 3.0 adapter for a desktop drive and hooking it to a SATA desktop HD. Maybe an SSD. But any ideas. I know any bottle neck in speed of drive, port speed, bus speed, etc, are all going to slow me down.
