We already did this unintentionally during our natural evolution. All we really got out of it were a group of humans who can run slightly faster on average, and a group of humans who can drink milk as adults without shitting themselves.
I imagine the timeframe to get any noticable results would be in the thousands of years, even with deliberate selection for specific genes.
Most hardrives live in servers, as part of storage volumes where IO can be optimised well beyond the capability of a single disk.
For the boot disk on my workstation I am absolutely using an SSD, but for the hundreds of terabytes of largely static data that I need to keep archived? Spinning disks all the way. Not only to SSDs need to match on price, but they also have a long way to come in terms of longevity.
