Just on the market is the new OWC Mercury Extreme Pro RE 400GB solid state drive.
Laptop users looking for a single drive should be looking at the 480GB model, but anyone looking for the ultimate MPG Pro Laptop will want two of these puppies installed for an 800GB double-speed volume (I currently run dual 200GB models = 400GB in my MacBook Pro, which is plenty of space for me).
I received two samples for testing, and I tested them both as single drives, and in a RAID-0 stripe.
The OWC Mercury Extreme line is the best choice on the market today for Mac users.
400 vs 480GB
Like the other 50/100/200GB Mercury Extreme Pro RE models, the 400GB version is a RAID-ready model with 28% over-provisioning that supports intensive 24 X 7 usage in heavy duty environments.
Mercury Extreme Pro RE = RAID-0 ready for extreme heavy duty usage, 28% over-provisioning
Mercury Extreme Pro = not intended for RAID, 7% over-provisioning with 20% higher capacity
The 60/120/240/480GB Mercury Extreme Pro line has 7% over-provisioning, which is still 7% more than most brands, and still very robust. With 20% more capacity, that’s the smart move for single-drive use (prices are similar). But if you are thinking of moving to RAID-0 striping for more performance or capacity, then stick with the RE line.
