DDP — Dynamic Drive Pool

High-performance shared storage optimised for media & entertainment workflows

What is a DDP?

DDP stands for Dynamic Drive Pool, a powerful shared storage solution designed specifically for demanding multimedia workflows.

Manufactured by Ardis Technologies in Arnhem, Netherlands, every DDP is an Ethernet SAN that allows multiple workstations — Windows, macOS, and Linux — to access the same files simultaneously, regardless of file size. Since 2003, DDP products have been sold worldwide through a selection of authorised resellers, including Mediaspec. Customers range from post-production facilities, broadcasters, and rental companies to universities, colleges, schools, and houses of worship.

With its hybrid architecture (HDD + SSD), intuitive browser-based Control Panel, and support for massive capacity and bandwidth, DDP is the ideal solution for seamless 4K, 8K, and uncompressed video workflows.

As an appointed reseller of the DDP, Mediaspec proudly supports a growing roster of satisfied clients across academia, media, and the public sector. Among the institutions that rely on Mediaspec for seamless content delivery are the Welsh Assembly, Northumbria University, Canterbury Christ Church University, Blazing Griffin, Savalas Post, University of Sunderland, Big Mouth Audio, Kelvin College, City of Glasgow College, Ulster University, Waddell Media, plus many more thriving partners. Their success stories underscore the reliability, scalability, and ease‑of‑use that define DDP. To see the impact in action, read our case study on Northumbria University here.

Who Benefits from a DDP?

Educational Institutions

Universities and film schools needing centralised, secure storage for students and staff.

TV & Film Post-Production

Facilities requiring real-time collaboration on high-resolution video projects.

Music Studios

Multi-room facilities that need fast, low-latency shared storage for Pro Tools and other DAWs.

Broadcast & Live Events

Rental companies and broadcasters needing reliable centralised storage on location or in the facility.

Why Choose a DDP?

Real-time collaboration with ultra-low latency

DDP uses a full block-level Ethernet SAN architecture, meaning client workstations access storage directly at the block level — not through slower file-sharing protocols like SMB or NFS. The result is latency comparable to a locally attached drive, even when multiple editors are simultaneously working on the same project.

Customisable storage management and allocation

Rather than a one-size-fits-all volume, DDP gives administrators granular control: create dedicated Folder Volumes per project or department, assign storage quotas on a per-volume basis, and adjust allocations dynamically as project demands change — all without moving or reorganising data.

RAID protection against drive failure

All DDP systems distribute data across multiple independent RAID groups. This not only protects against individual drive failure, but enables the system to continue operating and serving data to clients while a failed drive is replaced — minimising any disruption to production.

SSD caching for significantly faster performance

Unlike competing systems that apply a global cache setting, DDP allows SSD caching to be configured on a per-volume basis. High-priority projects can be assigned dedicated cache, ensuring consistent performance where it matters most, without cache contention from lower-priority workloads.

Auto-mounting of volumes on desktop login

DDP integrates with user account management so that the correct volumes are automatically mounted when a user logs in. Editors and students see exactly the storage they need — and nothing more — without manual configuration or IT intervention for each session.

Easy-to-use web-based administration

The browser-based Control Panel requires no client software on the administrator’s machine. System health, volume usage, user permissions, and RAID status are all visible and configurable from a single interface, accessible from any device on the network.

Highly scalable architecture

DDP systems are designed to grow with your organisation. Additional DDP units or third-party storage arrays can be added to an existing deployment without disrupting live workflows. Capacity and bandwidth scale independently, allowing you to address specific bottlenecks as they emerge.

Broad application compatibility

DDP is validated with the leading professional media applications, including Avid Pro Tools, Avid Media Composer, Blackmagic DaVinci Resolve, Adobe Creative Cloud, Apple Final Cut Pro, Grass Valley, Dalet, Fairlight, and Sony. If your facility relies on any of these tools, DDP is designed to support them natively.

Pricing

The HyperDDP 12D system costs only £12,500 plus  VAT and includes 36TB of RAW storage

Higher models offer greater flexibility in storage, networking, and bandwidth. Thanks to the modular architecture, you can expand capacity and performance step-by-step as your needs grow. Contact our team for a quote tailored to your requirements.

Key Technologies

SSD Caching

SSDs can handle the demanding read/write cycles of audio and video production, but their cost still exceeds that of traditional hard drives. A hybrid system combining SSDs and spindle-based HDDs can take advantage of intelligent caching to get the best of both. Unlike other manufacturers who apply a global cache setting across the whole system, DDP lets you configure caching on a per-volume basis — aligning cache allocation directly with project priority for a markedly more efficient workflow.

Load Balancing

Rather than relying on one massive RAID array, a DDP spreads data across several smaller RAID groups. This Load Balancing prevents any single group from becoming a bottleneck. As additional disks and RAID sets are introduced, access latency drops and overall throughput climbs. Because the workload is shared among multiple, evenly utilised groups, no single segment becomes congested — allowing the storage subsystem to sustain far higher data rates than a single, oversized RAID configuration could ever achieve.

Folder Volumes

Unlike traditional file-based NAS systems, DDP lets you turn any folder into a virtual Folder Volume. Once created, these mount on client desktops and behave like normal internal drives with full block-level access. For example, Avid Media Composer always places media files in a “MediaFiles” folder at the root of a volume. On a large shared system this quickly becomes disorganised. With Folder Volumes, administrators can create a dedicated volume per project, keeping everything clean and simple to manage — without any underlying data restructuring.

Quotas & Permissions

DDP supports per-volume storage quotas, allowing administrators to allocate guaranteed space for each volume. Access control permissions (read / write / delete) can be configured per individual user, desktop, or user group. Quota control is dynamic: when a job needs a burst of additional space, the quota can be temporarily expanded and snapped back once ingest is complete — without the overhead of reshuffling data.

Ardis Virtual File System (AVFS)

At the heart of every DDP is the proprietary Ardis Virtual File System (AVFS), which seamlessly manages any combination of HDDs and SSDs while delivering outstanding performance and reliability. A DDP system enables full project and file-level sharing, utilising almost 100% of the available Ethernet bandwidth.

Log In and Go

Managing users in a storage system doesn’t have to be complex. DDP can be configured to automatically mount individual volumes based on the user’s account — so the correct volumes simply appear when someone logs in, without needing to access the DDP backend or connect through additional client software.

In environments with a high turnover of users — such as educational institutions where students enrol and graduate each year — administration can otherwise become cumbersome. With DDP, user accounts can be created, grouped, and assigned access to Folder Volumes in an automated way using scripts or Excel exports from Active Directory, saving administrators significant time and effort.

The DDP Product Range

Six product families cover everything from portable field production to petabyte-scale broadcast infrastructure. All systems run the Ardis Virtual File System (AVFS) and are managed through the same browser-based Control Panel.

 

HyperDDP 12D

Entry-level — from £15,000 + VAT

The entry point to the DDP ecosystem. The HyperDDP 12D is a hybrid HDD + SSD Ethernet SAN suited to smaller teams of 4–8 workstations working with compressed or lower-resolution media. It delivers solid shared storage performance without the complexity or cost of higher-tier systems, and is fully expandable should your requirements grow.

Note: Comes with 1 year of support rather than the standard 2-year warranty that applies to all other DDP models.

 

Hybrid DDP Series

DDP12D • DDP16D • DDP24D • DDP24DF

The workhorse of the DDP range. These modular Ethernet SAN servers have the file system and metadata management built in, supporting Windows, macOS, and Linux simultaneously. They sit between the entry-level HyperDDP and the high-end DDP10EF, and are the most widely deployed DDP systems in post-production facilities, music studios, and universities. Capacity and bandwidth scale as you add drives or attach additional storage — making these the natural upgrade path for facilities outgrowing simpler solutions.

 

Micro DDP Series

Service & Warranty

Standard Warranty

Every DDP system purchased through Mediaspec is covered by a 2-year manufacturer’s warranty from Ardis Technologies, covering hardware defects and component failures under normal operating conditions. The one exception is the entry-level HyperDDP 12D, which comes with 1 year of support.

Under the warranty, Ardis Technologies will — at no charge and at its option — repair or replace any part of the product which proves defective by reason of improper workmanship. In the event of a drive failure, a replacement component is typically shipped within two business days of the fault being identified.

Extended Support

Support can be extended by a further five years beyond the standard warranty period. Hardware and software support can be purchased together or separately on an annual basis, with pricing dependent on the DDP model. Extended support is only available for systems currently under an active support contract, though reinstatement may be considered in some circumstances.

Remote Connection Requirement

A remote connection is mandatory for warranty and support, and should be tested at installation. This is how Ardis diagnoses and resolves issues — both hardware and software problems are addressed remotely in the first instance.

The recommended approach is a service connection where the operator decides when to initiate the remote session. During the connection, a secure shell tunnel is established via port 22 outgoing to a fixed address at Ardis Technologies. If a customer has security concerns about this approach, Ardis will work with them to agree an alternative remote access method.

Mediaspec’s Role

As an authorised Ardis reseller, Mediaspec can provide an optional support package throughout the warranty period and beyond. If you experience an issue, our team can act as a direct point of contact — coordinating with Ardis on your behalf to minimise disruption to your workflow.

For facilities requiring extended coverage or enhanced service-level agreements — such as guaranteed response times or on-site support — please contact us directly to discuss the options available.

Frequently Asked Questions

The number of concurrent users depends on the model and network configuration. Entry-level systems like the HyperDDP 12D are well suited to smaller teams of 4–8 workstations, while higher-tier models with 25GbE or 100GbE networking can support significantly larger teams. Contact us with your workflow requirements and we can recommend the right configuration.

 

DDP uses standard Ethernet, so your existing network switch can often be used. The ideal setup depends on distance and required performance: fibre supports longer runs, and for maximum throughput, especially with 4K or 8K uncompressed workflows, clients can be connected directly to storage.

For best performance, a dedicated network segment or VLAN is recommended to isolate storage traffic. Managed switches with jumbo frame support (9000 MTU) are advised. Our team can help assess your network and recommend the right configuration before purchase.

Yes. DDP’s modular architecture means you can add additional drives to an existing system, or attach further DDP units and third-party storage arrays as your needs grow. Capacity and bandwidth can be expanded independently, so you are not locked into a fixed configuration at the point of purchase.

DDP is validated with the leading professional media applications including Avid Pro Tools, Avid Media Composer, Blackmagic DaVinci Resolve, Adobe Creative Cloud, Apple Final Cut Pro, Grass Valley, Dalet, Fairlight, and Sony. If you use an application not listed here, contact us and we can confirm compatibility.

Yes. DDP supports simultaneous multi-platform access, so a mixed environment of Windows, macOS, and Linux workstations can all connect to and work from the same storage system concurrently.

DDP distributes data across multiple independent RAID groups, so a single drive failure does not take the system offline. The failed drive can be replaced while the system continues serving data to connected workstations. Under the standard warranty, Ardis Technologies will ship a replacement component within two business days of the fault being identified.

Not necessarily. The browser-based Control Panel is designed to be accessible to non-specialist administrators. Routine tasks such as creating users, assigning volumes, and monitoring storage usage are straightforward. For more complex tasks — such as scripted user provisioning via Active Directory — some IT familiarity is helpful, but full-time IT support is not a requirement for most deployments.

Lead times vary by model and configuration. Contact our team for current availability and an accurate delivery estimate for your specific requirements.

Not Sure Which DDP Is Right for You?

Choosing the right shared storage system is a significant decision, and the best configuration depends on factors specific to your facility — the number of workstations, the resolution and codec of your media, your existing network infrastructure, and your plans for growth.

Our team has extensive experience specifying and deploying DDP systems across post-production, broadcast, education, and music production environments. We are happy to discuss your requirements in detail and recommend a system that fits both your workflow and your budget.
