Don’t overspend—not which Mac to get or how to configure it? Consult with MPG Lloyd.
The OWC Accelsior 4M2 PCIe SSD has 4 slots for M.2 NVMe SSD modules. It is shipped with SoftRAID to combine those 4 modules into a single volume. As tested here, it was configured as a single RAID-0 stripe volume. It is also possible to configure it as 4 individual volumes (one per blade), or dual 2-blade volumes, or a RAID-4, and a variety of other possibilities, all courtesy of SoftRAID. Super fast and easy no matter what.
Results: speed across entire capacity, large I/O sizes
In modern parlance: OMG OMG OMG!!!!! This performance obliterates any SSD ever tested by MPG, doubling previously top-end speeds. Not enough? Two cards can be set up as an 8-blade RAID with speeds that should hit 10-12 gigabytes per seconds, which is fairly pointless, but very cool.
Next, see the speed versus transfer size graph, also impressive.
Results: speed vs I/O size
Holy upside bat shit fast, batman! Speed with only 256 KiB transfers already approaches maximum speed of any Apple internal SD and by 512 KiB, the OWC Mercury Accelsior 4M2 trounces the very fastest Apple internal SSD at its best. The Accelsior only gets faster from there!
