Product Highlights

Astonishingly, Mind-Blowingly Holy Cow Fast

Whether it leaves you speechless in amazement or uttering colorful phrases, the Accelsior 8M2 can be summed up in one definitive sentence: It’s the fastest, highest-capacity PCIe SSD in the galaxy. This beast destroys performance barriers and every PCIe SSD on the market today. So much so that we considered naming it the Annihil8r! We continuously push the boundaries of SSD capabilities so you can realize your true potential. With the Accelsior 8M2, we’re taking you beyond your wildest dreams and into the most demanding applications imaginable with certified reliability. From M&E postproduction to real-time AI, to huge dataset climate research… you now have the power to confidently reach higher.

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 space for up to eight NVMe M.2 SSDs, Accelsior 8M2 offers scorching speeds of over 26,000MB/s and industry-leading storage capacity. Now you have the overhead to go faster, process more, and save almost limitlessly.

Ultra-Reliable Design

Creating the fastest PCIe SSD meant combining bold engineering with the latest technology. Each of the Accelsior 8M2’s eight NVMe M.2 SSD slots can run at their full x4 lanes of data throughput. All that insanely fast speed is pumped through a full PCIe Gen 4 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.

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 visualizations 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
Crushes I/O Intensive Apps

When work requires your storage device to deliver maximum IOPS (Inputs/Outputs Per Second) performance, the Accelsior 8M2 crushes data-crunching tasks in a fraction of the time. Cloud applications, climate research, virtualization apps, you name it…the Accelsior 8M2 accelerates them all so you can work more efficiently.

Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
