Hard drive and SSD technology improvements continue

[MeercatMilker]

I have an OWC Mercury Extreme Pro 3G for over a year now. It's a 512GB SSD but only shows 480GB - as the remaining data is for over provisioning which allows more efficient wear leveling - so the drive keeps the same speed over time.
Assembly is in the USA too which eliminates most faults and failures.

OWC also have a 960GB SSD out but that's a RAID-0 combo of two 480GB (512GBx2) drives. I would stay away from that because of the dangers inherent to RAID-0.

Those OWC drives are quick under normal conditions, but the moment you use drive encryption they bog down to half their normal speed. I looked seriously at the 6G, but the sandforce controller was a no go for my needs as i have to encrypt my data.
