  1. Auxiliary power cable required for use in the Mercury Helios.

  2. Not compatible with OWC Mercury Helios 3.

  3. Benchmark testing conducted in March 2017 using a 2.93 GHz Quad-core Intel Xeon Mac Pro with 32GB of RAM and a 960GB 3G SSD. Testing conducted on a OWC Mercury Accelsior Pro Q PCIe SSD with 480GB of flash memory. This PCIe device was installed in the PCIe 2.0 x16 slot. QuickBench 5.0 Extended Test was performed using 10 cycles, with 'Asynchronous I/O' and 'Allow Cache Effects' disabled. Black Magic Speed Disk Test (version 3.0) was performed using the 5GB 'Stress' setting. AJA System Test (version 10.3.3) was performed twice: the 4K (4096x2160 10-bit RGB) 'DiskWhack' test with a 'File Size' of 16.0 GB, and the 1080p (1920x1080 10-bit) 'DiskWhack' test with a 'File Size' of 16.0 GB. [AJA 'Streams' test results depict 'Frame Rate' settings of 23.98, 29.97, and 60 frames per second.] Results represent the extended test average.

  4. Bracket not included in measurements. The "Width" measurement refers to the card's thickness. Notice: currently the Accelsior Pro Q is approximately 4 mm out of spec for a Full Height PCIe card. For this reason it may not fit in some PCIe expansion chassis.
