Maybe it's just me, but rare harware isn't something I'd look for in a reliable storage system unless I had a really special need general hardware just couldn't be made to do
Per sibling comment, "unique" is a better descriptor than "rare". The NAS is made in Taiwan and has been readily available from Amazon or QNAP store.
The Marvell CN913x SoC has been shipping for 5 years, following the predecessor Armada SoC family released 10 years ago and used in multiple consumer NAS products, https://linuxgizmos.com/marvell-lifts-curtain-on-popular-nas.... Mainline Linux support for this SoC has benefited from years of contributions, while Marvell made incremental hardware improvements without losing previous Linux support.
Rare more means a unique combination of common hardware products, where other manufacturers don't put all of the features into one piece of hardware like qnap or others might, to keep people buying more devices to get what they want, or buy a device that is way too overkill for their needs.
