#SOFTRAID VS APPLE RAID UPGRADE#
Thus, it’s possible to upgrade the flash storage blades inside if the need ever arises in the future. Removing these screws and removing the heat sink will expose the flash modules, which can each be individually accessed via screwdriver. There are five torx screws that hold the giant heat sink on the outside of the unit securely against the four flash storage modules inside.
#SOFTRAID VS APPLE RAID INSTALL#
Accessing the drivesĪlthough I imagine that most users who purchase the OWC Accelsior with preinstalled flash storage will simply want to install the drive and start using it, it should be noted that it’s possible to open the unit to access the flash media inside. For that reason, I encourage you not to use a RAID 0 setup for storing irreplaceable data, and always make backups. Although flash storage failure is much less likely than it is on traditional spinning mechanical hard drives, it still remains a possibility. Obviously RAID 0 comes with one big caveat, and that’s the fact that if one drive fails, the entire array, and all of your data, will be lost. With all of that being said, users who purchase the Accelsior, especially the smaller storage configurations, will probably want to stick with RAID 0, as it provides the greatest amount of storage at the best performance. While Apple RAID Assistant is limited in the type of RAID configurations possible, SoftRAID, which OWC provides a free license for upon purchase of the Accelsior, allows for a wider range of RAID configurations, such as RAID 5. Users have the option of configuring the OWC Accelsior 4M2 via SoftRAID (preferable) or via the built-in Apple RAID Assistant. The 4TB is not a single unit of flash storage, but it’s actually comprised of four 1TB M.2 SSDs in a RAID 0 configuration. OWC provided me with a 4TB unit with a total of 3.84TB of usable storage space. Available now in 1, 2, 4, and 8TB configurations.
Full x4 PCIe speeds per SSD via on board PCIe switch.
Over 6,000MB/s real world speed in RAID 0.Installs into a full-height, half-length x8 or x16 PCIe 3.0 or 2.0 slot.But the Accelsior 4M2 may also a viable option for MacBook Pro users looking to add external external storage to their laptops via a simple Thunderbolt 3 enclosure. OWC’s newest Mac Pro-friendly accessory allows users to add a significant amount of fast solid state storage to their machines in just a few minutes. With the Mac Pro we finally have a modern Mac that can be expanded, not only via external Thunderbolt 3 peripherals, but via internal PCIe cards like the OWC Accelsior 4M2 PCIe SSD. One of the great things about the Mac Pro, and the primary reason why I’ve been anticipating it so much, is its ability to accommodate PCIe expansion.
