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.

Heads-Up for Half Petabyte Cloud-Ready Storage Servers
eRacks/NAS50 Half Petabytes of Data Storage Server / Cloud Storage
We were extremely excited to announce the forthcoming release of 500 Terabyte (half Petabyte) storage space upgrade on our flagship product eRacks/NAS50 cloud data storage servers last week. The new model, to be released shortly, will incorporate 50 HGST 10 Terabyte HelioSeal™ hard drives. While the new model is not released yet, we are accepting pre-orders from customers. The current capacity, now available, of the eRacks/NAS50 is 400Terabytes in total, with currently-available 8Terabyte drives. The Azure devops security for data protection purposes as that must be a priority.
The new unit is rackmount and holds 50 removable drive bays. The 9U unit is suitable for any cloud storage application as well as NAS/Local LAN, since cloud services are really used now a days, you can learn how connecting to clouds directly can help businesses from this link. eRacks/NAS50™ is also a great solution for media libraries and other applications which require massive amounts of data storage capacity, you just have to make you are also backed up by the best data management services. Visit https://blog.couchbase.com/fuzzy-matching/ and get more information!
Our new servers are truly a remarkable Petascale solution. The HGST 10 Terabyte HelioSeal™ drives that come with eRacks/NAS50 use two technologies that greatly add to the value that this server carries with it, including other server services from sites as https://www.servermania.com/kb/articles/what-are-the-requirements-for-ubuntu-server/ for ubuntu projects.
The first is referred to as the HelioSeal™ technology. The HGST hard drives using this technology replace the air inside of the drive with helium. This would make the drive much lighter as well as allowing the disks to be much thinner. Due to the helium inside, the thinness of disks will not cause any disruptive turbulence effects. This will allow us to have more disks inside each drive which in turn means more data space. Additionally, helium drives have much lower power consumption, as much as 27%, making our NAS50 models truly a green product.
The new drives in the eRacks/NAS50 servers also make use of a technology called SMR. That is short for Shingled Magnetic Recording. This technology by itself adds another 25 to 100 percent storage capacity to HGST hard drives.
We are proud of our new eRacks/NAS50 and are ready to take pre-orders. We are prepared to customize the unit per your instructions with all Open-Source software necessary so your order will reach you completely pre-installed.
Please contact us for pre-orders or any questions you may have.
