For drives it was relatively easy, though we would have to eventually just use the next bigger size. All of our RAID systems would handle that just fine. Drive quality never really was an issue, even in the "Deathstar" days... The bigger standardizing issue was the system. We use Supermicro barebones, and between memory and CPU changes, we would have to qualify a couple-three new chassis every couple of years. And those chassis were much more expensive than a disk drive. Mostly, Supermicro quality was very good. With the exception of around a year or 18 months where the power supplies they were using all failed roughly a year after we bought them. We had older and newer servers with no problem, but around 30 in the middle all failed.
