AJA in comparison reached 2.1 and 2.17GBps, still plenty fast for most use cases. A folder containing ten 10GB files was transferred in 77 seconds. We tested it on a Dell XPS 15 and CrystalDiskMark speeds pretty hit the headline speeds at 2.76 and 2.725GBps in read/write. Note that every drive is serviced by only one PCIe lane and is not multiplexed - each drive is allocated up to 700MBps (or 2.8GBps in total), so one might argue that the P12 is overkill. While the maximum theoretical speed of Thunderbolt 3 is 5GBps but in reality, this number is never reached due to overhead. OWC claims that the P12 can hit read/write speeds of 3.4GBps and 3GBps respectively (and individually) which should be more than enough for each channel. OWC, which owns SoftRAID, is also testing a Windows version of SoftRAID that also offers RAID-1. Use either the bundled SoftRAID software (for Mac) or Windows’s Disk Management’s feature. You have to configure the drives to work in RAID-0 (striped) in order to extract the maximum performance from the setup. Better to put the drive vertically so that the fan pushes the air sideways rather than on a flat surface. The drive is loud it reached 77dB making it less than ideal for acoustic/audio workflows.
