GetOWC Thunderbay 4 Mini SSD RAID Edition at MacSales.com.
Following up on yesterday’s overview of OWC 40TB Thunderbay 4 Mini SSD, here is performance.
This is the best performance MPG has ever seen with Thunderbolt 2 (or from any external SSD). It sets the new benchmark.
- Read performance flatlines at 1425 MB/sec
- Write performance flatlines at 1192 MB/sec
Those are average figures across across a gigantic 39.37TB volume! Context: those figures beat the internal 1TB SSD in the MPG 2013 Mac Pro.
There looks to be cruising room here for 4K raw video capture. Or any hyper demanding task for writes and even better for reads.
It looks like Thunderbolt 2 has throttled the read performance. MPG expects OWC to offer a similar solution with Thunderbolt 3 in 2017, in which case the read speeds should rise to even higher levels.
Write @ 1137 MiB/sec = 1192 MB/sec, Read @ 1359 MiB/sec = 1425 MB/sec

A wide range of capacities is available. Capacity rating reflects usage as RAID-0 stripe or single drives. Using in RAID-5 mode means that 1/4 of the capacity used for parity, e.g., reducing 40TB to 30TB usable capacity.
