Which is better, Synology DS923+ or TerraMaster F4-424 Pro?

The Synology DS923+ 4-Bay Diskless NAS is the stronger software-first pick, while the TerraMaster F4-424 Pro 4-Bay Diskless NAS has faster built-in networking and a more powerful processor. Both models have 4 drive bays, so the key difference is the balance between operating system and hardware.

Synology’s DiskStation Manager is a strong fit for buyers who want a clear path to backups, file sharing and remote access. The DS923+ starts with 4GB of ECC memory and has two 1GbE ports, with optional 10GbE support. TerraMaster’s F4-424 Pro pairs 32GB of memory and an 8-core processor with dual 2.5GbE ports, making it attractive for heavier local workloads.

Choose the DS923+ for Synology’s software and expansion options. Choose the F4-424 Pro for faster built-in Ethernet and stronger specifications out of the box.

Which NAS should you choose for Black Friday 2026?

The Synology DS923+ 4-Bay Diskless NAS is the best all-round choice for buyers who want 4 bays, reliable backup tools and a system that grows with a home office. The TerraMaster F4-424 4-Bay Diskless NAS is a practical alternative when two 2.5GbE ports matter more than Synology’s software environment.

For an entry-level setup, the Synology DS224+ 2-Bay Diskless NAS keeps the drive count and management simple. The TerraMaster F2-424 2-Bay Diskless NAS offers dual 2.5GbE in a compact enclosure. Buyers with larger libraries or multiple users can step up to the Synology DS1522+ 5-Bay Diskless NAS.

Skip it if the network, drive count or apps do not match your setup: a NAS is most useful when it solves a specific storage or backup need. Check drive compatibility and the manufacturer’s current support information before adding disks.

How many NAS drive bays do you need?

A 2-bay NAS such as the Synology DS224+ 2-Bay Diskless NAS is a straightforward fit for a personal backup library, while a 4-bay model gives a household or small office more room to grow. Bay count describes the number of internal drives the enclosure accepts, not how much storage comes included.

Mirroring two drives helps protect against a single drive failure, but it does not replace an independent backup. Four bays allow more flexibility when balancing capacity and redundancy, and larger models such as the Synology DS1522+ 5-Bay Diskless NAS provide another step up.

Plan around usable capacity rather than adding every drive’s label capacity together. Storage layouts use some capacity for redundancy, and actual available space varies by drive size and configuration.

Does 2.5GbE matter on a home NAS?

Dual 2.5GbE ports on the TerraMaster F4-424 Pro 4-Bay Diskless NAS and TerraMaster F2-424 2-Bay Diskless NAS offer more network bandwidth than a standard 1GbE port when the rest of the network supports those speeds. A faster NAS port alone does not make every transfer faster.

A computer, switch or router, cabling and the storage drives all contribute to real file-transfer performance. Buyers with a standard 1GbE home network still get useful storage from a 2.5GbE NAS, but they need compatible networking gear to use the higher connection speed.

For ordinary document backups and occasional streaming, software and storage capacity are often more important than the fastest Ethernet specification. For large video files or several users transferring files at once, faster ports are more relevant.

Are Synology and TerraMaster NAS systems diskless?

All seven models in this guide are diskless NAS systems, so the Synology DS923+ 4-Bay Diskless NAS and TerraMaster F4-424 4-Bay Diskless NAS require separately purchased drives. Diskless models give buyers control over drive brand, capacity and configuration.

Use NAS-rated drives listed as compatible with the model, and check each manufacturer’s current drive compatibility guidance. Mixing capacity or drive types affects the storage layout, so decide on redundancy and usable space before filling the enclosure.

A NAS is also not a complete backup by itself. Keep a second copy of important files on another device or service, and make sure a restore process is part of the plan.

Buying Guide

1. Match the bay count to your storage plan

The Synology DS224+ 2-Bay Diskless NAS suits a smaller start, while the Synology DS923+ 4-Bay Diskless NAS gives a home office more room. Count present files and planned growth, then account for capacity used by redundancy.

2. Compare network speed with your other gear

The TerraMaster F4-424 4-Bay Diskless NAS and TerraMaster F2-424 2-Bay Diskless NAS include dual 2.5GbE ports. A compatible router, switch and computer are required to use that faster connection.

3. Choose software for the jobs you need

Synology DiskStation Manager is a key reason to choose the Synology DS923+ 4-Bay Diskless NAS. Compare backup, file-sharing and media applications before choosing between Synology and TerraMaster systems.

4. Check the hardware headroom

The TerraMaster F4-424 Pro 4-Bay Diskless NAS combines an 8-core processor and 32GB memory. Lighter file sharing does not need the same hardware as a busy multi-user server, so match specifications to your workload.

5. Budget for drives and an independent backup

Each diskless NAS requires separate drives, and RAID or mirroring does not replace a second copy. Include compatible drives and a separate backup destination in the full storage plan.
