Business and production NAS users where downtime or package breakage would be a serious problem.
Users relying on Mail Station or Synology Mail Server, because these are no longer supported in DSM 7.4.
Third-party drive users expecting Storage Efficiency to work everywhere.
Older NAS owners who can install DSM 7.4 but may not gain the headline features.
Users upgrading mainly for AI, because the current DSM Agent is still early and some major AI services are expected later.
Anyone who needs a NAS today should not wait on an unreleased product unless the Gen 3 features are essential.
Users who require confirmed slot-by-slot NVMe bandwidth should wait for final PCIe lane specifications.
Budget buyers should wait for price confirmation; all-flash NAS plus NVMe SSDs can escalate quickly.
AI buyers should wait for real testing of the local AI stack, memory requirements and security model.
If you were interested in Flashstor Gen 2 but hesitated because of graphics, HDMI, USB4 direct-connection expectations or the lack of a stronger local-AI roadmap, the Flashstor Gen 3 is absolutely worth watching. If your priority is proven performance and immediate availability, current Flashstor Gen 2 models remain the safer known quantity until Gen 3 receives final specs, pricing and a full review.
