eRacks Expands NAS Lineup: 11 Models, 4 Bays to 100 Bays, From $1,995

eRacks Open Source Systems has expanded its rackmount NAS server lineup to 11 models, spanning from the 4-bay NAS4 at $1,995 to the 100-bay NAS100 at $29,995. The expansion targets the accelerating cost pressure of cloud storage subscriptions versus on-premise alternatives, with full Linux, ZFS, TrueNAS, and Ceph support across the entire range – and zero per-TB licensing fees.

The math behind on-premise NAS in 2026

Storing 100 terabytes on Amazon S3 costs roughly $27,600 per year in standard-tier fees. The same 100 TB sitting on an eRacks NAS24 – 24 bays, ~480 TB raw capacity – is a one-time $8,995 purchase. Payback is under four months.

Then there are egress fees. A single 100 TB pull from AWS to your office costs around $9,000 just to get your own data back. Cloud storage made sense when the data was small. At terabyte and petabyte scale, the math has flipped.

The lineup at a glance

Model	Bays	Form Factor	Price (starting)	Best for
NAS4	4	1U or desktop	$1,995	Branch office, dev team
NAS6	6	1U	$2,995	Small office, light backup
NAS8	8	2U	$4,995	SMB primary file server
NAS12	12	2U	$5,995	SMB with growth headroom
NAS16	16	3U	$6,995	Mid-tier file + backup
NAS24	24	4U	$8,995	Mid-enterprise (the bestseller)
NAS36	36	4U	$10,995	Mid-large workloads, scale-out node
NAS50	50	4U top-load	$14,995	Media production, surveillance
NAS60	60	4U top-load	$19,995	High-density archive, large backup
NAS72	72	4U top-load	$24,995	Broadcast, large-scale archive
NAS100	100	4U top-load	$29,995	Petabyte-class, Ceph nodes

Plus a parallel all-flash NAS lineup for performance-tier workloads: FLASH10 ($5,995), FLASH20 ($9,895), FLASH24 ($8,995), FLASH48 ($15,995), and FLASH72 ($19,985) – all-NVMe arrays for database backends, AI training datasets, virtualization storage, and any workload that needs IOPS rather than raw capacity.

Open source the whole way down

Every eRacks NAS ships with full Linux – not a locked appliance OS – and supports your choice of:

• ZFS with ECC RAM for data integrity
• TrueNAS Scale for the friendly web UI experience
• Ceph for clustered scale-out
• MinIO for S3-compatible object storage
• Nextcloud for private cloud file sharing
• OpenMediaVault for the lightweight option
• Proxmox if you want NAS + VMs in one box

No vendor licenses. No per-TB fees. Full root access. You own the OS, you own the data, you own the hardware.

Hardware standards across the line

ECC RAM as standard. Hot-swap drive bays throughout. Redundant power supply options on NAS12 and above. NVMe SSD caching on larger models for accelerated reads. 25 GbE networking on demand for AI training workloads, video production pipelines, and large-scale backup.

The lineup also scales without chassis replacement. A NAS50 shipping with 24 drives today expands to 50 as needs grow – no forklift upgrade required.

When does it pay off?

For most organizations storing more than 5 TB of business data, on-premise NAS is cheaper than cloud subscriptions in year one. For HIPAA-aligned healthcare deployments, law firms protecting privileged data, or any organization with data sovereignty requirements, on-premise is not just cheaper – it is the right architecture.

Custom-built since 1999

eRacks Open Source Systems has designed, built, and shipped custom Linux servers since 1999. Every system is configured to order, burn-in tested before shipping, and supported directly by engineers who built it. No call centers, no upsell scripts, no per-feature licensing.
