A very fine performer, the new 1TB OWC Mercury Extreme Pro 6G SSD delivers high performance on both compressible and incompressible data within a tight performance envelope. It looks eminently suitable for RAID use.
While OWC has offered the 1TB Mercury Electra 6G 1TB for a good while and it is a fine performer (MPG uses one for an external backup), the EXTREME Pro 6G line had been maxed out at 480GB for several years.
As of late 2015, the EXTREME Pro 6G now has a new high-capacity part, the 1TB OWC Mercury EXTREME Pro 6G SSD. At about $429, it offers excellent value with its 5-year warrant and 30-day money back guarantee.
