If you listen to all-flash array vendors's shiniest, happiest, propaganda, you'll learn that moving from disk to solid state storage will more or less immediately turn your organisation into a white-hot innovator. Flash puts you in with a chance of both becoming the Uber of [insert your industry here] and avoiding an Uber-reaming by some new competitor where not a single employee has ever owned a suit.
Just add Flash, the story goes, and habitual suit-wearers and shareholders alike will sail away into the sunset on yachts they bought courtesy of a soaring share price.
What they're not saying in public is that flash arrays can also make a royal mess of your current rigs, in two ways.
The first mess Flash can create is on your network, which almost certainly wasn't built to handle the kind of input/output per second (IOPS) Flash arrays can deliver. Networks may therefore choke/stutter/collapse once asked to handle more data than they've seen in years. Hardened IT pros know this. Folks who read about Flash in an airline magazine, or a business magazine in an airline lounge, are going to need some education about adopting all-Flash arrays requiring a bit more work than is required to wield an RJ45 clip.
