Works fine on MBP 13” (Early 2015) with macOS Sierra 10.12

Works perfectly fine, and was great at verifying which drive/connection combo bottleneck was the worst, and what to expect from others. I used it on the internal SSD, a SanDisk 960 GB SATA III SSD using an Apricorn USB 3.0 to SATA connection, an Addonics 5-disk array in RAID 5, and a WD 4 TB HDD in a USB 3.0 connected external enclosure.
