High-Performance PCIe NVMe M.2 SSD Adapter Card

Build The Fastest SSD Available
When OWC launched its first Solid State Drive in 2010, it was engineered to deliver the same attribute formula that Mac and PC users expected from OWC external storage solutions:

High performance + high reliability + affordable price = The OWC Difference

Nearly a decade later, our commitment to that winning formula remains steadfast as we push the boundaries of leading-edge SSD development with the Accelsior 4M2. It’s ideal for uncompromised, data intensive, high bandwidth needs like large format video editing, VR/AR/MR environments, high transactional and complex calculation applications, and extreme gaming.

Accelsior 4M2 houses up to four NVMe M.2 SSDs under a finned heat sink cover that provides silent, throttle-free cooling. Has been tested with over 6,000MB/s real-world speed with the highest reliability possible.
Highly Versatile with Mobile Possibilities
Whether you have the Mac Pro 2019, a Mac Pro 2012 or 2010, or PC tower, Accelsior 4M2 can go to work for you. As a half-length x8/x16 compatible card, this game-changer offers the versatility you need, so you’re not tied to one PCIe slot size or limited by a space-confined computer case.

You can also enjoy the performance boosting benefits of Accelsior 4M2 with your Thunderbolt 3-equipped notebook computer, iMac workstation, or slot filled gaming rig. It’s Plug and Play easy with a PCIe expansion chassis like the OWC Mercury Helios 3S.
Change Your Reality
Accelsior 4M2 offers performance gains in so many diverse ways that it will change your storage reality:
  • Stream and edit high-res video and graphics files without a glitch.
  • Experience faster previews, renders, and processing in VFX programs.
  • Keep page scenery and textures looking sharp and flowing uninterrupted in virtual reality environments.
  • Ensure augmented reality visualizations look life-like.
  • Change game levels seamlessly and play flight/driving/MMO games with continuously changing scenery and heavily personal preference modded games without micro-stuttering.
  • Give your computer a significant speed boost with improved system “snappiness”, a fast OS boot drive, or a bottleneck-free scratch drive.

All RAM upgrades supplied by Upgradeable have a lifetime warranty.
Our definition of lifetime warranty is: If the product ceases to work at anytime, you can return it for a replacement. Simple. No if's, no but's. Our RAM will out last your computer. We have had the same warranty since year 2000. It has never varied or been modified. Our competitors have played catch up and matched our warranty but they can never match our service. We don't provide a lifetime warranty as a gimmick, it is a statement on the values of our company, our goal of exceptional customer service and the quality of the products we supply.

SSD warranty (3 to 5 year )
Unlike RAM, an SSD has limited write cycles, so it will eventually wear out. However, it will take 10 years or more to wear out an SSD! Warranty varies from 3 to 5 years, please check the SSDs description. Our faulty SSD return policy is to make it as simple as possible for the customer. We will replace faulty drives as soon as they are returned.

14 Day Money Back Guarantee
Our money back guarantee is about your assurance that our upgrades will make a difference. If is not about how many days, it is about customer service and trust. We have had the same guarantees for 20+ years because they are sustainable. We have had to make some modifications. We now reserve the right to charge a 5% restocking fee. This is because the credit card processing fee is non refundeable to us, which means the bank keeps their charges. A refund costs us 5%.
