XCubeNAS Network Attached Storage
The lightest SMB multi-function data centre.
XCubeNAS is QSAN's NAS lineup, spanning everything from compact desktop towers to high-density rackmount units — all powered by QSM, the 128-bit ZFS-based operating system that treats data integrity as a first-class citizen. If you've ever lost data to silent bit rot on a cheaper NAS, you'll understand why ZFS matters.
What makes XCubeNAS genuinely interesting is the "N+X" hybrid drive tray design. It mixes 3.5" HDD bays with hidden 2.5" SATA/NVMe SSD slots, so you get automated SSD caching and tiering without sacrificing any of your main storage bays. Pair that with AES-256 pool encryption, SED support, and WORM for ransomware defence, and you've got enterprise-grade data protection in a box that an SMB can actually afford and manage.
The range includes rackmounts (XN8100R, XN8000R, XN7000R, XN5000R) and towers (XN8000T, XN5000T), with networking from built-in Gigabit up to 25GbE and Thunderbolt 3. Cross-platform file sharing, video editing, local backup, remote work sync — there's a model that fits the workload. It competes head-on with Synology and QNAP — but with ZFS data integrity, proper enterprise security, and that clever N+X chassis design.

Let's be direct: Synology and QNAP dominate the NAS market in Australia, and for good reason — they're well-known, widely available, and have excellent ecosystems. But QSAN's XCubeNAS brings something neither of them can match: a true 128-bit ZFS file system that inherently prevents silent data corruption. No bolt-on checksums, no afterthought — it's foundational. The N+X chassis design is also clever: you get dedicated SSD cache slots hidden inside the drive trays, so you don't sacrifice any HDD bays for caching. Add in enterprise-grade WORM and SED security that Synology and QNAP only offer at their very top tiers, and XCubeNAS is a seriously compelling alternative for organisations that value data integrity above all else.
One of the advantages of working with CRS — we can recommend the best combination of vendors for your specific needs.
NAKIVO
NAKIVO uses XCubeNAS as a backup repository target — NFS or SMB shares for VM backups with immutable WORM protection.
Keepit
Keepit handles SaaS data in the cloud while XCubeNAS manages local file shares and backup archives — complementary, not competing.
Proxmox
XCubeNAS provides NFS/iSCSI shared storage for Proxmox VE clusters — ISO libraries, VM templates, and backup destinations.
StoneFly
StoneFly DR appliances replicate critical XCubeNAS file shares to air-gapped offsite locations for disaster recovery.
QSAN XCubeNAS is available through Cloud Ready Solutions and our network of authorised partners across Australia, New Zealand, and the Pacific.
