The Thunderbay 4 Mini RAID-5 edition is available with SSDs in capacities from 1TB to 40TB. MPG strong recommends the RAID edition.

Thunderbay 4 Mini configurations (non RAID) are also available, as well as hard drive configurations are also available.

Added to my review of the OWC 40TB Thunderbay 4 Mini SSD is analysis of RAID-4 vs RAID-5 with the OWC 40TB SSD.

RAID-4 mode is 16% faster for reads, and it also touches the estimated asymptote for theoretical best performance (based on testing the SSDs singly).

The supplied SoftRAID deserves kudos for implementing RAID with performance that sets a benchmark; few if any hardware solutions can do this well.

Figures are in MiB/sec. Multiply by 1.048576 for MB/sec.

Sustained transfer performance with a 30TB RAID-4 vs RAID-5 SSD configuration in OWC Thunderbay 4 Mini
