OWC Express M42 - Speed seems slow on TB3

CORRECTION: OWC Express 4M2!

Hi, speed tests via Aja attached. Shouldn't the Thunderbolt 3 (MBP 14,3) speeds be faster? We were hoping to get closer to 2500 MBps.

- macOS Mojave 10.14.2
- OWC Express 4M2
- 4x Samsung 970 EVO 256GB SSD
- Dedicated bus
- SoftRAID configured RAID 0

- Mac Pro 6,1 (Thunderbolt 2 - see attached)
- Macbook Pro 14,3 (Thunderbolt 3 - see attached)...

The write speed actually looks inline with the 256GB sticks, which are rated at 1500... you need at least 512GB sticks to get 2300+ (see here). Can't explain the slow read speeds though...

Interesting. Significantly slower read speeds.
