Overview
Not a portable external drive, this is an internal disk meant to live inside a network storage box. Synology designed the Plus Series for constant use, with validation testing for multi-user environments.
The reason to buy is a drive validated by the same maker as the NAS it goes into. The limit is the modest spin speed and that the package holds just the one drive.
Who it's for
A small office with a Synology enclosure and users who read and write at the same time is the target. Anyone planning a gaming build or an external backup drive should look at other storage.
Pros and cons
- Made by the NAS maker
- Built for constant operation
- Tested for multi-user use
- Long warranty period
- Mechanical disk, slower than flash
- Modest spin speed
- Single drive in package
Performance notes
The drive is designed for constant uptime, so it favors steady reads and writes over peak speed. Two numbers are listed for transfer, one for the interface and one for sustained media speed. In a multi-user NAS, the controller and the number of drives affect overall results.
