NAS bay planner
People choosing a NAS enclosure. The decision this page isolates is narrow on purpose: translate disks and raid into a nas bay class. Fit and capacity are the expensive mistakes. Settle those before you commit to a finish or a brand.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Synology and UGREEN. It produces an explainable class so Synology DS220+, Synology DS423+, and UGREEN NAS DH2300 2-Bay for Beginners & Personal Users, Phone can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in Synology. This page does not quote a price or rank a brand.
How to use this calculator
