Soon to arrive for testing is an 8TB OWC Viper. The Viper will be available in 4TB or 8TB capacities configured as a hardware RAID-0 stripe or as a software RAID-4. For initial testing, the RAID-0 stripe version will be utilized.
- Configured as an 8 TB / 7.2 TiB stripe, OWC Viper performance will be throttled by Thunderbolt 2; it should redline at the maximum bus bandwidth of Thunderbolt 2.
- Configured as a 7TB / 6.3 TiB fault-tolerante RAID-4, OWC Viper performance is likely to be the same, because of the same Thunderbolt 2 bus throttling. The RAID-4 version will continue to operate even if one of the eight flash modules in it fails.
Thunderbolt 3 needs to arrive sometime soon! When devices are outstripping the bus bandwidth, it’s time for Apple to get its technology act together and deliver Thunderbolt 3 with its unified USB-C and HDMI 2.0. That changeover did not happen with the late 2015 iMac 5K.
