I bought one of the original OWC SSD's Code: 60GB Mercury Extreme Pro SSD 2.5" Serial-ATA 9.5mm Solid State Drive. High Performance internal MLC Flash storage with 7% Over Provisioned Redundancy. My question is, would a brand new 60 gig Mercury Electra 6g be a big enough difference to be worth replaceing the other SSD, or is the SSD to SSD different too small to worry about. I don't quite recall the benchmarks on the Mercury Extreme Pro SSD, but comparing that to the Electra 6g, is it worth updating to the new one? I really have no idea how to gauge this.
