NAS storage means network-attached storage units that keep files, backups and media on your own network, for home users, small offices and growing businesses. Our range of over 90 models is led by Synology, with ASUSTOR, QNAP and UGREEN also available. Check each product page to see whether drives are supplied or need to be bought separately.
How to choose a NAS
Number of drive bays. A two-bay NAS suits basic file sharing and a mirrored copy of your data. Four or more bays give you more capacity and allow RAID levels that combine speed with protection against a failed disk. It is usually sensible to buy one or two bays more than you need today.
RAID and drive choice. RAID keeps the NAS running if one drive fails, but it does not replace a backup. Pick drives sold for NAS use, as they are built for running around the clock. Capacity matters less than having enough bays to build the RAID layout you want.
Processor and memory. A basic processor copes with file sharing, backups and streaming to a few devices. If you plan to run virtual machines, containers, Plex transcoding or many users at once, look for a stronger processor and memory that can be upgraded later.
Network speed. Gigabit Ethernet limits transfers to roughly 110 MB/s, which is fine for documents and backups. Models with 2.5GbE or 10GbE ports suit video editing, large photo libraries and several people working on the same files, provided your switch and computers support the same speed.
Software and apps. The operating system decides how easy the NAS is to live with. Look at the backup tools, photo management, surveillance support, mobile apps and remote access options before you compare hardware.

- ASUSTOR: offers the ADM operating system and a mix of home and business models, including units with 2.5GbE and 10GbE networking.
- QNAP: known for feature-rich models with virtualisation and container support, and for higher-speed networking and expansion options on many units.
- UGREEN: a consumer electronics brand better known for chargers and cables, now also making NAS units with its own UGOS software for home users.
Also in our range: Ubiquiti and Lenovo.
NAS storage FAQ
Do I need a NAS at home?
A home NAS is worth considering if several people or devices need the same files, photos or media. It keeps everything in one place and can back up your computers and phones automatically. If you only store a small amount of data for one computer, an external drive may be enough.
Does a NAS come with hard drives?
Many NAS units are sold as empty enclosures, and you add the drives yourself. Some bundles include disks, so check the product page before ordering. Buying drives separately lets you choose the capacity and drive type that fit your budget.
Which RAID level should I choose for a NAS?
RAID 1 is the usual choice for a two-bay NAS, as it stores the same data on both drives. With four or more bays, RAID 5 or RAID 6 gives more usable space while tolerating one or two drive failures. Whatever you choose, keep a separate backup, because RAID does not protect against deletion, theft or ransomware.
What is the difference between a NAS and an external hard drive?
A NAS connects to your network, so many devices can reach it at once, at home or remotely. An external hard drive plugs into a single computer. A NAS also supports multiple drives, RAID protection, scheduled backups and apps, which a simple external drive does not offer.
