SSDs and disk bottlenecking
Some years ago I learned to have my virtual machines on a separate HDD because when on the same disk as the main OS there where performance issues. The reason: because it was a mechanical drive, with moving parts, when there were many requests for reads it had to prioritize.
From then on I always distributed things amongst as many disks as possible.
But what about SSDs? without moving parts would there be a performance penalty all the same? Even if minimal? Is it feasible to have, say, a 2 TB SSD with everything on it (OS, VMs, games) with several apps running simultaneously?
Thanks in advance.
