Indeed this is bad and I would like to know that this is something that can be reproduced, but I guess there will be more and more similar situations.
It is probably true to say that the number of users needing an SSD volume on their NAS is relatively small, especially when you get into model specifics (although this may also impact those who use SSD caches I guess).
There will be some real pain felt by those who followed the Synology recommendation to the letter and purchased IronWolf SSDs. At the time, this was the Synology's vendor of choice for SSDs, with bespoke options in DSM and the (questionable) ability to revise firmware via DSM. In actual fact the SSD that they purchased SSDs would go on to be artificially crippled by a firmware update from DSM itself.
Not that the Synology-badged SATA SSDs have arrived here in the UK in any meaningful numbers. You can at least order them on Amazon with a 4 to 6 week delay for the dizzying price of £1,172.95 for a single 3.8TB SSD. Clearly it make no sense for anyone to buy a new empty Synology NAS impacted by this if you cannot get the SSDs to make it work.
For my current 6 drive volume it would cost me an additional £7037.70 to make the Critical warning go away, plus at least 1 spare SSD to cover the availability issues. Grand total of £8210.65 (€9644.00) extra, plus downtime, just to restore the same functionality I had... all for use on a £1k consumer Linux box.
