New vs Seasoned OWC Mercury Pro RE 200GB
The OWC Mercury Pro RE has 28% over-provisioning, which means that 28% of its memory is set aside for error correction, bad blocks, and performance enhancements. It is an enterprise-grade unit with a rated MTBF of 10 million hours, about 8 times longer than the best hard drives! Unlike some SSDs, it has no memory buffer, which is a very good thing should the power fail: no data loss.
As of April 2010, the OWC Mercury Extreme is the only SSD that I now feel confident recommending.
Performance brand-new and after seasoning
