Obliterates Workflow Bottlenecks

As storage performance innovators, we know 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, video editors have the real world speed for sustaining the most demanding VFX, color, 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.

Redefines SSD Reality

Creating the fastest PCIe SSD meant combining bold engineering with the latest technology. Each of the Accelsior 8M2’s eight NVMe SSDs can run at their full x4 lanes of PCIe data throughput. All that insanely fast speed is pumped through a full PCIe x16 lane architecture. And to ensure Accelsior 8M2 keeps running at peak speed for the long haul, there’s a quiet cooling fan in the aircraft grade aluminum heat sink. No compromises. No surrender. Just the ultra-reliable performance that Mac and PC users have come to depend on from OWC storage solutions.

Traffic Jam

The data traffic flow design of most SSDs looks like too many cars trying to merge onto a crowded freeway at rush hour.

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 huge benefit in knowing you can work as fast as possible. Every second 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:

Media professionals on film set
  • 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 12K 16bit format.
  • 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.

By eliminating the need to remove a reel and renders from their current storage platform, this company can shave up to two days from their production schedule. The Accelsior 8M2 could reduce production costs for this company with typical production projects of 10 reels of film by an estimated $8,000 per project. This revolutionary SSD is a seriously smart investment.

Takes Data to the Edge

The Accelsior 8M2 is a high-performance NVMe-based storage solution that delivers consistent low latency data throughput. It's perfect for 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.
