The RAID-0 stripe of 4 X 2TB SSD (8TB volume) delivers a consistent 2.64 GB/sec real-world throughput through file system APIs, which is very close to the limit of the Thunderbolt 3 bus (2.75 GB/sec) and identical to the performance of the OWC Thunderblade.

Average RAID-0 MB/sec: 2636 write, 2638 read

Vertical scale is MB/sec. Horizontal scale shows percentage of volume capacity, e.g., 50% is 4TB used of 8TB.
