Quatre SSD M.2 NVMe regroupés sur une seule carte d'extension PCIe 3.0 demi-longueur : voilà ce que propose le OWC Accelsior 4M2 16TB, une solution de stockage pensée pour les stations de travail vidéo professionnelles. Le cœur du dispositif repose sur un commutateur PCIe intégré qui alloue à chaque module son propre lien x4 complet, là où les cartes quadruples bon marché se contentent de partager la bande passante en x2. Résultat concret : jusqu'à 6318 Mo/s en lecture séquentielle et 6775 Mo/s en écriture séquentielle lorsque les quatre blades OWC Aura Ultra III sont agrégées en RAID.
Sous le capot ailettes en aluminium passif, quatre contrôleurs Phison PS5012-E12 pilotent de la NAND 3D TLC synchrone avec cache SLC et 7 % de surprovisioning, un trio qui tient la latence d'écriture lors d'une ingestion de plusieurs heures. Le refroidissement silencieux évite tout bruit mécanique sur un plateau de tournage ou dans une cabine de doublage sensible. La carte s'installe dans tout connecteur PCIe 3.0 ou 2.0 x8 ou x16 : Mac Pro 2019 et 2023, Mac Pro 2010-2012 « cheese-grater », ainsi que les tours Windows HP Z, Dell Precision ou Lenovo ThinkStation.
La licence SoftRAID fournie débloque les modes RAID 0, 1, 4, 5 et 1+0 ainsi que le JBOD, avec surveillance SMART par module, alertes prédictives de défaillance et prise en charge TRIM sur les NVMe internes sous macOS — un atout que l'Utilitaire de disque d'Apple ne couvre pas pour les blades PCIe. Les postes DIT sous DaVinci Resolve, Premiere Pro ou Avid Media Composer gagnent un volume de scratch capable d'encaisser du ProRes RAW 8K multi-flux, des séquences DPX 4K non compressées et des timelines de conformation BRAW 12 bits sans recourir aux proxys.
Le Accelsior 4M2 16TB trouve sa place au-delà de la post-production : déchargement des magasins ARRI ALEXA 35, RED V-RAPTOR ou Sony VENICE 2 entre deux prises, serveurs de diffusion broadcast avec pool média protégé, captations live multi-ISO issues de vMix, TriCaster ou OBS. Un des quatre blades peut rester hors du RAID et servir de disque système macOS bootable pendant que les trois autres forment le stockage média. La garantie limitée de 5 ans OWC et le support technique direct du constructeur closent une solution pensée pour des studios qui facturent à l'heure.

Our Not-So-Secret Winning Formula
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 32TB 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.
The Performance Advantage of NVMe
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 delivers extreme data rates that will change the way you work or play.
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 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.
More Lanes = Faster Throughput
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.
2 to the Second Power
When over 6,000MB/s real world speed and 32TB of capacity isn’t enough to satisfy your needs, you can RAID two Accelsior 4M2 cards together to experience out of this world performance.
Change Your Reality
Accelsior 4M2 offers performance gains in so many diverse ways that it will change the reality of how you use a storage solution:
- 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 lifelike.
- Change game levels seamlessly and play flight/driving/MMO games with continuously changing scenery and heavily 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.
