Accelsior 4M2
Meet the fastest OWC SSD ever built
At an unprecedented 6,000MB/s, Accelsior 4M2 harnesses the power of M.2 NVMe technology to achieve breakthroughs in large format video editing, VR/AR/MR environments, and extreme gaming.
At an unprecedented 6,000MB/s, Accelsior 4M2 harnesses the power of M.2 NVMe technology to achieve breakthroughs in large format video editing, VR/AR/MR environments, and extreme gaming.
When OWC launched its first Solid State Drive (SSD) 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 = 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, virtual reality/augmented reality/mixed reality environments, high transactional and complex calculation applications, and extreme gaming.
Under Accelsior 4M2’s s finned heat sink cover that provides silent throttle-free cooling reside four Phison E12 M.2 NVMe SSDs with up to 16TB of storage capacity. These “blade” style SSDs utilize Triple-Level Cell (TLC) 3D NAND with SLC caching and 7% over-provisioning.
All those “ingredients” combine to deliver over 6,000MB/s real-world read and write speeds with the highest reliability possible to satisfy the biggest storage performance appetite.
Non-Volatile Memory Express (NVMe) is a communication standard specifically built to optimize the performance of modern flash technology. It enables significantly faster SSD performance vs an SSD using the SATA interface, a communication protocol that was originally designed for hard disk drives. With NVMe SSDs powering its heartbeat, Accelsior 4M2 offers the fastest data rates ever delivered by an OWC SSD.
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 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 (sold separately).4 Helios 3S lets the Accelsior 4M2 flow with your workflow by offering up to 2,500MB/s real-world read/write performance in the field on your notebook.5 Once back at your desk, the choice is yours…keep Accelsior 4M2 in the Helios 3S or install it into your Mac Pro 2019 to enjoy its blistering fast 6,000MB/s capabilities.
Accelsior 4M2 was designed with a PCIe switch to let your computer address each of the M.2 NVMe drives at full x4 PCIe speeds instead of hard-limiting each drive to x2 PCIe speeds. When running in JBOD, where all four drives are typically not accessed at the same time, each drive has the unlocked capability to run at full speed.
When over 6,000MB/s real world speed and 16TB of capacity isn’t enough to satisfy your needs, you can RAID two Accelsior 4M2 cards together to experience out of this world performance.
Accelsior 4M2 offers performance gains in so many diverse ways that it will change the reality of how you use a storage solution:
Now you can maximize disk space, get the fastest access speeds, and protect against disk failure with Plug and Play simplicity. SoftRAID’s easy setup makes it a breeze to create RAID volumes by helping you through the entire process. Just decide what you’re using your RAID volume for and how much space to allocate to it. It's that simple to create your preference of speed and/or redundancy attributes of your data volume.
OWC enclosures ship with the XT version of SoftRAID. SoftRAID XT and Lite XT are fully featured and designed to only work with OWC solutions. Click here to learn more.
We understand having confidence in gear reliability is paramount to creative professionals. That’s why every Accelsior 4M2 pre-configured solution undergoes a multi-step performance certification prior to shipping. This ensures your Accelsior 4M2 arrives operating properly and immediately ready for demanding use.
