Who each option suits

Households replacing a PC-dependent media library

A NAS is relevant when TVs, phones, tablets or computers need local access to personal media without leaving the main computer on. Plex Support advises checking the intended devices and any transcoding requirements before choosing a NAS for media-server duties.

Single-computer library managers needing more capacity

An external drive or direct-attached enclosure can suit a library mainly organised from one desktop or laptop, provided that computer can remain the point of access. OWC and Plex Support describe direct-attached storage as a computer-centred arrangement rather than a standalone household server.

Families protecting irreplaceable photos and documents

Choose a separate backup destination alongside the main library when photos and documents cannot easily be replaced. Synology Knowledge Center and the National Cyber Security Centre both distinguish drive redundancy from an independent backup, and an off-site copy adds protection against risks at home.

Buying priorities

Start with where the media server will run, then check playback compatibility, usable capacity and the protection needed for files that matter.

Priority What to check Your needs
Access while the PC is off Decide whether the library needs a host computer, or whether a NAS must be reachable over the home network. Check media-server apps on each intended TV, console, phone and tablet. I want household devices to reach the library without relying on my main computer being switched on. A NAS or another always-on server is the more suitable arrangement.
Playback compatibility List common containers, codecs, bitrate, resolution and subtitle use. If the NAS will run the server, check its exact processor architecture and transcoding support for those files and clients. I need the files I use most to play on the screens and devices around my home. Plex Support notes that Direct Play depends on compatible file formats and client capabilities.
Capacity and recovery Calculate current files, expected growth and backup copies separately. For multi-bay systems, check usable capacity after the chosen RAID layout, drive sizes and redundancy allowance. I need room to grow without treating a mirrored array as my only safeguard. Keep an independent backup destination, with an off-site copy for important files where appropriate.
Remote access and accounts Keep local access as the default where possible. Check update support, unique accounts, strong passwords, MFA or 2SV, and whether remote access can avoid direct port forwarding. I may want access away from home, but I do not want to expose NAS administration services unnecessarily. The National Cyber Security Centre recommends using an extra verification step for protected accounts.

Mistakes to avoid

  • Treating a mirrored or RAID-protected array as the complete backup plan

    A NAS or enclosure can still be affected by failures, deletion, ransomware or an incident affecting the whole home. Synology Knowledge Center warns that RAID crashes and hard-drive failure can still lead to major data loss, while the National Cyber Security Centre recommends a recent offline backup for important files.

    Plan the primary library and backup storage as separate purchases. For important files, keep three copies on two media types with one copy off-site, and test that you can restore files.

    Independent protection requires capacity for an additional backup drive or an off-site backup destination.

  • Buying a NAS based only on drive bays or advertised network speed

    A NAS may hold media successfully but still struggle if its server must convert incompatible video, subtitles or remote streams. Playback depends on the files, client devices, expected simultaneous users and whether transcoding is required.

    List the most demanding regular files, subtitle types and playback devices. If the NAS will run the media server, verify the exact model against the relevant media-server compatibility guidance.

  • Enabling remote access through automatic router exposure without checking settings

    UPnP, port forwarding and direct public exposure can increase the attack surface. QNAP UK recommends disabling unnecessary exposure and keeping firmware and applications updated; relay-style remote access can also be slower.

    Begin with local-network access. If remote use is necessary, use a supported method that avoids unnecessary direct exposure, restrict access to named accounts, enable MFA or 2SV, and keep software current.

  • Assuming a direct-attached enclosure works when the computer is off

    A USB or Thunderbolt enclosure adds capacity and can offer RAID options, but it is designed around a connected host computer. It does not become a standalone network server simply because it contains several drives.

    Choose direct-attached storage only when a connected computer is acceptable as the library host. Select a NAS or another always-on server when independent household access is the main requirement.

    Changing later to independent household access may require a NAS, an always-on computer or a different media-server host.

Synology

A NAS platform for households that want network storage, user accounts, backup tools and optional media-server use in one appliance.

  • Synology Knowledge Center describes backup options using different destinations and security controls including MFA, password rules and automatic blocking.
  • Media-server suitability remains dependent on the exact NAS model, client devices, file formats and any transcoding demand.

QNAP

A NAS option for households seeking multi-bay network storage, with local HDMI output, 2.5GbE networking and hardware-accelerated transcoding available on selected models.

  • QNAP UK lists the TS-264 with two 3.5-inch bays, two 2.5GbE ports and hardware-accelerated transcoding.
  • Drives are bought separately, and secure setup still requires compatible drives, current updates and careful remote-access configuration.

OWC

A direct-attached storage-enclosure option for a computer-centred library where Thunderbolt connection, multi-drive capacity and configurable RAID matter more than standalone network access.

  • OWC describes ThunderBay 4 as a Thunderbolt four-bay enclosure that can use RAID software for performance and drive-failure tolerance.
  • It relies on a connected computer workflow and RAID remains separate from an independent backup.

Synology DiskStation DS925+ 4-Bay NAS

Synology DiskStation DS925+ 4-Bay NAS

A network-storage option for a growing household library that needs access without the main computer running.

Western Digital Elements Portable 4 TB External Drive

A computer-attached option for expanding a single-computer media library or keeping an additional local copy.

Stated 4 TB capacity with USB 3.2 Gen 1 connectivity and an included cable.

Frequently asked questions

Is RAID the same thing as backup?

No. RAID can help a multi-drive system continue after certain drive failures, but it does not create an independent copy. Synology Knowledge Center advises backing up to a different destination, and important files benefit from a separate backup with an off-site copy.

How much storage capacity should I buy?

Calculate the current library, expected additions and backup copies separately. In a redundant multi-drive array, usable capacity is lower than the raw total, so check the chosen RAID layout and drive sizes before assuming all installed space will be available.

Will every TV, phone or console play every file from a NAS?

No. Plex Support states that Direct Play depends on a compatible container, codecs, bitrate and resolution on the specific client device, and subtitles can require transcoding. Check the files and subtitles used most often on every important playback device before choosing a NAS to run the server.

When do I need a more powerful NAS instead of a basic file-storage NAS?

More processing power matters when the NAS itself must run a media server and convert incompatible video, subtitle streams or remote streams. If it only stores files while the server runs elsewhere, concentrate first on usable capacity; otherwise, verify the exact model’s processor architecture and transcoding capability for your intended workload.

How should I set up remote access to a NAS safely?

Avoid making direct internet exposure the default. QNAP UK recommends disabling unnecessary UPnP, DMZ and port-forwarding settings; use separate accounts, strong passwords, MFA or 2SV where available, and keep firmware and applications updated before enabling remote access.
