They already created Red Pro for business use, and market it as "Designed and tested for RAID environments 8-16 Bay NAS", at a 37% markup relative to the Red in my market. My quick Google sleuth indicates those are not SMR. The Red line is marketed as "Designed and tested for RAID environments 1-8 Bay NAS", which implies they're for more than just a 2-bay Synology box.
Either way yeah this was an attempt at a cash grab. Which was quite stupid, because there's no way they'd be able to hide the fact that it's SMR for long, the performance characteristics is just too different.
But it's also totally unnecessary, because SMR is perfectly fine for use-cases with sparse random write workloads. Something most casual home users or small businesses with a 1 or 2 disk Synology or similar has.
