New vs Seasoned OWC Mercury Pro 240GB
The OWC Mercury Pro has 7% over-provisioning, which means that 7% of its flash memory is set aside for error correction, bad blocks, and performance enhancements.
Its RAID-0-ready sibling, the Mercury Pro RE has 28% over-provisioning (200GB capacity). Both variants are outstanding choices. Choose the 240GB Pro model for single-drive use, or the 200GB model for ultra-high performance RAID-0 use.
As of April 2010, the OWC Mercury Extreme (either model) are the only SSDs that I feel confident recommending. Either the Pro or the Pro RE models are great choice for the MPG Pro Workstation or MPG Pro Laptop, depending on workload and/or whether RAID-0 striping is used.
