Silent Cubes for compliant archiving with WORM storage
Silent Cubes are hardware WORM storage systems for organizations that need to store data securely, demonstrably unalterable, and cost-efficiently for years.
The solution is suitable for legal archiving, GDPR retention, audit trails, and long-term storage of documents, files, images, and other critical data. With Zero Loss storage, digital audit, and modular expansion, you maintain control over compliance, storage costs, and availability.

Why choose Silent Cubes
Many organizations store data much longer than before. Think of medical records, financial documents, legal information, research data, production documentation, or other data with a legal or business-critical retention period.
Silent Cubes are developed for situations where data must not be lost, cannot be modified unnoticed, and must remain demonstrably reliable even after years. The hardware WORM technology ensures that stored data is protected against modification and deletion at a lower level than software settings.
The benefits at a glance:
- Hardware WORM storage for unalterable archiving
- Suitable for compliant archiving and long retention periods
- Digital audit for data integrity control
- Low energy and management costs for long-term storage
- Scalable from a few terabytes to petabyte level
- Replication to a second location possible
- Suitable for organizations with compliance, audit, or retention obligations
Why Silent Cubes for compliant archiving?
WORM sealing, Erasure Coding, Digital audit.
Excellent security against data loss, hardware failure and misconfiguration
Modular configuration, expansion by adding memory modules.
Particularly low power and operating costs, highly scalable to petabytes
Managed Storage – our promise.
Comprehensive FAST LTA on-site service with hardware replacement with full data retention
Silent Cube DS Pro for modern archive applications
Systems with larger storage capacities usually also require higher performance. That is why we have now equipped the 16, 32, 64, and 128 TB models with 10G Ethernet, redundantly of course. Together with the latest Head Unit Pro, this enables installations with an end-to-end 10G infrastructure. Ideal for new modalities and modern archive applications that need that little bit extra.

Silent Cubes in your archive environment
Silent Cubes fit seamlessly into your network structure.
01. Clearing online storage of data rarely used creates free storage space
02. Significantly lower acquisition, management and energy costs
03. Shorter backup and recovery times for online storage due to less data traffic
04. Silent Cubes archive storage is highly secure, replicable and requires no additional data protection.
Benefits of Silent Cubes as WORM archive storage
Highest security
With conventional hard disk storage, user error cannot be completely eliminated. However, the FAST LTA WORM controller protects data from erasure and overwriting at the lowest hardware level.
To protect against batch failures, 4 hard drives from 3 production batches are used per Cube. The redundancy coding of a Silent Cube with 4 redundancies is more secure than a mirrored RAID6 configuration – with a better gross/net ratio.
The data are regularly and automatically checked bit by bit within the storage unit by means of a digital audit. Faults can thus be detected and corrected at an early stage.
Scalable and modular
Silent Cubes storage systems are scalable to more than 4,000 terabytes. You can add storage units at any time to adjust capacity to meet your growing needs.
Silent Cubes offer a compact, award-winning design and are designed for 19-inch rack mounting.
To protect against the loss of an entire system, for example due to fire or water damage, the Silent Cubes installation can be replicated to a second location. The software required for this is included with the system at no additional cost.
Energy & cost savings
Silent Cubes are certified as CAS (Content Addressed Storage) for compliant archiving and thus meet the relevant legal requirements – at a convincing price. Special features include low operating and energy costs.
Silent Cubes consume less than 2 watts per long-term storage unit in standby. Energy requirements for power and cooling are lower than any other long-term storage.
Installation, maintenance and expansion of the Silent Cubes require exceptionally low personnel costs, saving you money on your IT budget.
All-round worry-free service
FAST LTA offers comprehensive service as part of the Silent Cubes maintenance contract. Upon request, we are available 24 hours a day, 7 days a week. In case of failure, FAST LTA replaces the affected components via on-site service with full preservation of the data stored on the long-term storage media. Software updates and hardware costs are also fully covered.
Integrated monitoring (e-mail, SNMP) provides insight into the status of the system at any time via a web browser and regularly informs FAST LTA via e-mail. This allows FAST LTA to proactively ensure the safe, smooth operation of your system.
Flexible archive storage with FLEX and STAR
Flexible billing for your archive storage: With FAST LTA FLEX , we offer billing for Silent Cubes Pro systems based on actual capacity used.
As with cloud-based storage, you only pay for what you actually use. We provide expansion, maintenance and all updates.
Second location without the need for a second location: with FAST LTA STAR, we provide protection for your Silent Cubes system in the event of a disaster.
Your local system (or your first FLEX instance) is replicated in our data center. This means that your data is always backed up, even in the event of a total failure.
Frequently asked questions about Silent Cubes
What are Silent Cubes?
Silent Cubes are hardware WORM storage systems for long-term archiving. They are developed for organizations that need to store data securely, unalterably, and demonstrably reliably. Think of documents, files, images, research data, or other data with a legal or business-critical retention period.
What do you use WORM storage for?
WORM storage is used when data must not be modified or deleted after storage. WORM stands for Write Once, Read Many. This is important for compliant archiving, audit-proof storage, legal retention obligations, and situations where you must be able to prove that data has not been modified since storage.
What is the difference between Silent Cubes and Silent Bricks?
Silent Cubes are primarily intended for compliant archiving and long-term WORM storage. Silent Bricks are mainly suitable for backup, recovery, VTL, and air gap storage. In short: you use Silent Cubes for data that must remain unalterably stored for years, Silent Bricks for data that must be quickly and safely recoverable.
Are Silent Cubes suitable for compliant archiving?
Yes. Silent Cubes are developed for compliant archiving with hardware WORM, digital audit, and protection against modification or deletion. This makes them suitable for organizations that must comply with internal compliance requirements, legal retention obligations, or oversight by auditors and regulators.
How do Silent Cubes help with long-term storage?
Silent Cubes help with long-term storage by storing data securely and efficiently without it having to remain continuously on expensive primary storage. The solution is scalable, energy-efficient, and designed to keep data available, verifiable, and protected for the long term.
Can Silent Cubes help to reduce storage costs?
Yes. By moving archive data from primary storage to specialized archive storage, organizations can save on capacity, management, and energy consumption. Silent Cubes are specifically intended for data that must be kept for a long time, but does not need to be on fast production storage every day.
