How it works

1. The official specification table

Every scored figure comes from an official Synology, QNAP or ASUSTOR specification table, linked on the product card. If a figure is not published we show "Not listed" and score it at the category minimum, so an unpublished number never outranks a published one. We do not use retailer listings or brochure speed claims in place of the official table.

2. Different jobs, different weights

Compact and 4-bay NAS units are weighted toward official installed memory, the fastest official onboard Ethernet port, official CPU core count and official port count. Multi-bay NAS units are scored on official bay count, official installed memory, official onboard Ethernet and official CPU core count. Optional PCIe Ethernet is not scored as onboard speed.

3. Match it to the desk, the rack and the network

A higher official bay count is not automatically the right NAS for a quiet desk or a shallow rack. Official form factor, dimensions and Ethernet speed help you match the install path. Use the official PSU, keep vents clear, change the default password, and remember that RAID is not a backup. Then check the price on Amazon. Commissions never change the order.
