NAS

NAS hardware in plain English: what the spec sheet numbers mean, and which drives, memory and UPS units work with which Synology and UGREEN models.

This section covers network-attached storage for homes and small offices, and the parts a NAS owner adds over time: hard drives, memory upgrades and uninterruptible power supplies. Every number on these pages is checked against the manufacturer’s own documents, such as datasheets, user manuals and compatibility lists, and each page lists those sources with the date they were checked. Each figure then comes with what it means in practice: how much space you keep, what happens to your data when a drive fails, which add-on actually fits your model.
