ASUSTOR vs Synology vs QNAP: Which NAS Brand Suits You? (Australia)

A neutral, source-based comparison of ADM, DSM, QTS and QuTS hero: snapshots, RAID, backup, remote access and surveillance.

ASUSTOR, Synology and QNAP all make capable NAS for Australian homes and businesses, and the right choice depends on the software you want to live with. ASUSTOR runs ADM and pairs it with well-specified hardware, a 3-year warranty on every model, MyArchive removable drives and four free camera channels. Synology runs DSM, with its own backup suite (Hyper Backup, Active Backup for Business) and Synology Hybrid RAID. QNAP offers two operating systems: QTS (ext4) and QuTS hero (ZFS, with self-healing and inline deduplication).

ARC IP Networks is a trusted ASUSTOR supplier in Australia: genuine ASUSTOR NAS and accessories at competitive prices, with the full ASUSTOR manufacturer warranty, Australia-wide delivery and trade pricing. We also sell QNAP NAS, so this comparison is about fit, not favourites. Every brand fact below comes from that brand's own published pages.

The real difference: ADM vs DSM vs QTS and QuTS hero

All three brands sell hardware, but you spend your time in the software. Each operating system runs in a web browser, has mobile apps, and handles RAID, users, shared folders, backups and an app store. The differences are in emphasis.

ASUSTOR ADM

ADM is Linux-based and looks like a tablet home screen. ASUSTOR's current release, ADM 5.1, adds post-quantum (PQC) TLS encryption, stronger password rules, firewall profiles for EZ-Connect and Docker, and local facial recognition in Photo Gallery. ASUSTOR-only features include MyArchive, which turns a spare bay into a removable archive slot, and Btrfs snapshots on its ARM-based Drivestor Gen2 and Drivestor Pro Gen2 as well as its Intel and AMD models. Our ADM explained guide goes deeper.

Synology DSM

Synology describes DSM as the operating system that powers every Synology NAS, with DSM 7.4 as its current release. Its package list leans into business data protection: Hyper Backup, Snapshot Replication on Btrfs (including immutable snapshots), and Active Backup for Business, which Synology says backs up Windows PCs and Macs with bare-metal recovery and global deduplication. Synology also offers Synology Hybrid RAID (SHR and SHR-2), which it recommends for drives of different capacities.

QNAP QTS and QuTS hero

QNAP is the only one of the three to offer a choice of operating system. QTS uses the Linux kernel and ext4. QuTS hero uses ZFS, which QNAP says checksums every data block and repairs errors automatically (self-healing), supports inline deduplication and RAID-Z with triple parity, and allows up to 65,536 snapshots. QNAP also notes that ZFS benefits from as much memory as possible, so QuTS hero suits higher-specification hardware.

RAID, mixed drives and snapshots

This is where the brands genuinely differ in philosophy.

  • ASUSTOR deliberately does not offer hybrid RAID. Its knowledge base explains why: mixed drive sizes and ages can slow an array, rebuilds carry more risk with old drives, and capacity is wasted. ASUSTOR recommends same-capacity drives, and suggests MyArchive for old drives instead. Standard RAID 1, 5, 6 and 10 are all available on four-bay models.
  • Synology recommends SHR or SHR-2 (Synology Hybrid RAID) when you combine drives of different capacities, to minimise unused space.
  • QNAP QuTS hero uses ZFS RAID-Z, with triple parity and triple mirror options, and QNAP says RAID-Z capacity can be expanded with a single drive.

If you buy matched drives up front, as most people do, all three approaches work well. Our NAS RAID guide explains RAID 1, 5, 6 and 10 on ASUSTOR, and choosing NAS hard drives covers which drives to buy.

Hardware: compare models, not logos

Each brand sells a wide range of models, and hardware changes with every generation, so compare the exact models you are considering rather than the brands. Look at:

  • Processor and memory: x86 (Intel or AMD) for Docker, virtual machines and Plex transcoding; ARM for simple file serving and backups.
  • Network ports: 2.5GbE suits most homes; 5GbE and 10GbE matter for video teams.
  • M.2 slots for SSD cache or fast storage, and whether they are PCIe 3.0 or 4.0.
  • Warranty and local support, and whether drives are included.

For reference, here is what ASUSTOR publishes for the models we stock most often:

ARC IP Networks suggestions based on each brand's published features.

Already own one brand? Staying with it is usually the easiest path, because accounts, apps and backup jobs carry over. ASUSTOR's system migration lets you move drives from one ASUSTOR NAS to a newer one; moving between brands means copying data across.

Where ASUSTOR stands out

  • Warranty: ASUSTOR lists 3 years for every model in our range, from the Drivestor 2 Gen2 to the Flashstor 6 Gen2.
  • Fast networking for the price: 2.5GbE on the Drivestor Gen2, dual 2.5GbE on the AS5404T, dual 5GbE on the Lockerstor 4 Gen2+ and dual 10GbE on the Lockerstor 4 Gen3.
  • MyArchive: removable, encryptable archive drives for cold, off-site backups.
  • Snapshots on entry models: Btrfs Snapshot Center runs on the ARM-based Drivestor Gen2 and Drivestor Pro Gen2.
  • Four free camera channels in Surveillance Center.
  • All-flash options: Flashstor models hold only M.2 NVMe SSDs.

Buying a NAS in Australia: what to check with any brand

  • Genuine local stock with the full manufacturer warranty, and a supplier who will help with claims.
  • Drives on the brand's compatibility list, ideally NAS-rated drives such as Seagate IronWolf.
  • A UPS, so the NAS shuts down cleanly in a blackout (see does a NAS need a UPS).
  • Your NBN connection type if you need remote access, because CG-NAT can affect direct connections on any brand (see remote access).

Common questions

Straight answers from the ARC IP Networks team. Last reviewed October 2026.

Neither is better for everyone. ASUSTOR pairs ADM with well-specified hardware, a 3-year warranty on every model, MyArchive and four free camera channels. Synology DSM offers Synology Hybrid RAID and Active Backup for Business. Choose by the software features you need.

It depends on your priorities. ASUSTOR ADM is simple and runs Btrfs snapshots even on entry models. QNAP offers QTS on ext4 and QuTS hero on ZFS, with self-healing, inline deduplication and up to 65,536 snapshots. ARC IP Networks sells both.

ASUSTOR uses ADM (ASUSTOR Data Master), which is Linux-based. Synology uses DSM (DiskStation Manager). QNAP uses QTS, based on the Linux kernel and ext4, or QuTS hero, based on the Linux kernel and ZFS.

No. ASUSTOR has chosen not to offer hybrid RAID, citing speed, rebuild risk and wasted capacity with mixed drives. It recommends same-capacity drives in an array and suggests MyArchive for older drives.

All three include strong backup tools. ASUSTOR offers Backup and Restore, Cloud Backup Center, DataSync Center, Backup Plan for Windows and Time Machine support. Synology offers Hyper Backup and Active Backup for Business. QNAP offers Hybrid Backup Sync.

Yes. ASUSTOR Surveillance Center includes four free camera channels, Synology Surveillance Station lists over 20,000 compatible IP camera models, and QNAP QVR Pro includes 8 channels, expandable to 128.

Not directly. ASUSTOR system migration moves drives between ASUSTOR NAS models. To change brands, copy your data to the new NAS over the network or from a backup.
