Product Information


OWC Accelsior 8M2

Whether it leaves you speechless in amazement or uttering colourful phrases, the Accelsior 8M2 can be summed up in one definitive sentence: it’s the fastest, highest capacity PCIe SSD in the galaxy.

Obliterates Workflow Bottlenecks

As storage performance innovators, OWC knows that bottlenecks cramp your style. The Accelsior 8M2 was purposely created to be the fastest drive you can use in any workflow. With eight on-board NVMe SSDs and speeds up to 12,000MB/s on the PCIe Gen 3 equipped 2019 Mac Pro, video editors have the real world speed for sustaining the most demanding VFX, colour, and high-end video editing including seamless playback of...

  • 16 streams of 8K ProRes444 in Final Cut Pro X
  • 8 streams of 12K ProRes444 in Final Cut Pro X
  • 9 streams of 4K 16bit EXR in DaVinci Resolve

Now you have the overhead to go faster, process more, and save almost limitlessly.

Unlimited Possibilities

Accelsior 8M2 offers performance gains in so many diverse ways that it lets you create without limits…

  • Stream and edit multiple high-res video streams without a glitch
  • Experiment with larger formats and be closer to final work
  • Edit and store massive photo images and graphics files
  • Experience faster previews, renders, and processing in VFX programs
  • Keep page scenery and textures looking sharp and flowing uninterruptedly in virtual reality environments
  • Ensure augmented reality visualisations look life-like
  • Effortlessly store and work with multiple production libraries and applications
  • Run more iterations in DevOps in less time
  • Quickly offload essential data to cloud archives for more advanced IoT management

When Survival Depends on Reliable Performance

Government agencies, companies, and institutions need the ability to reliably access and quickly analyse enormous data files to make decisions. The Accelsior 8M2 is ideal for “big data” geospatial apps used by emergency management organisations to process real-time conditions, such as natural disasters like a fire or flood. Officials making life-saving decisions can count on the Accelsior 8M2 to deliver actionable data in extreme situations where every second matters.

Reduces Timelines and Project Budgets

Whether you’re a Media and Entertainment production pro or a transportation logistics wizard, there’s one ever-present formula that affects your success:

Time = Money.

There’s a priceless benefit in knowing you can work as fast as possible. Every microsecond saved adds up to money saved for your company. Case in point, a multiple Academy Awards winning film production company is currently using the best available storage technology, but still has workflow limits. Here are some of the company’s problems that could be solved by implementing the Accelsior 8M2...

  • Not enough capacity to store multiple reels, so they have to shuttle reel media between the main ingest drive and slower external storage devices
  • The time-consuming process of accessing a finished reel on external drives
  • Struggling with drive space-saving methods like flattening project layers, which requires re-rendering layers you’re working in
  • Not enough speed to view real-time playback. Playback must be viewed in several different modes to determine effects of filters and adjustments
  • Not enough speed to ensure smooth playback of industry’s emerging 8K and 10K 16bit film

Takes Data to the Edge

As a high-performance NVMe-based storage solution, Accelsior 8M2 delivers the consistent low latency data throughput required in edge computing applications such as industrial automation, smart city ecosystems, and smart retail solutions. It feeds CPUs and GPUs huge amounts of data lightning fast for real-time predictive analytics. If your business provides data-driven services to customers, any lag in service could frustrate customers accustomed to instant information and lead to irreparable brand damage. With 60% of storage professionals using NVMe SSDs to process large data sets generated at the edge, Accelsior 8M2 is more than a competitive advantage…it is a best practice.

Includes SoftRAID XT: Easy and Complete Drive Management

SoftRAID XT is the most powerful, intuitive software RAID utility on the market. Multiple RAID options let you select the RAID level that fits you or your project’s needs best. If you need maximum volume capacity, optimum drive performance, data protection, or a combination of attributes, SoftRAID has you covered.

Packed with features like drive validation, verification and failure prediction—SoftRAID includes features you simply don’t get with hardware RAID. It’s like having a data centre on your desktop! From home users looking to protect photos and documents to professionals needing to protect and quickly access projects, SoftRAID is the perfect solution.

  • Advanced: create RAID 0/1/4/5/1+0 (10) arrays
  • Protected: SoftRAID monitor constantly watches your disks and alerts you if problems are detected
  • Validated: volume validation ensures sectors can be read and parity is correct
  • Certified: checks disks before use to ensure they are safe for data storage
  • Vigilant: error prediction helps protect against unexpected failure
  • Universal: move SoftRAID arrays seamlessly between Macs and PCs with built-in OWC MacDrive technology

SoftRAID provides a level of performance that you simply can’t get with hardware RAID.
