Corsair Switches to 25nm in the Force Series
Corsair has announced a transition from 34nm to 25nm manufacturing technology for the Force series solid-state drives. The company cooperates with SandForce to make the transition as smooth as possible. Apparently Corsair has been satisfied so far with performance and reliability tests.
The transition to 25nm should lead to increased storage capacity and reduced costs, but the problem is that the smaller chips are not as durable as previous generations. To solve the problem the SSD manufacturer needs more over-provisioning, meaning that an increasing amount of cells have to be assigned for wear leveling. Consequently, 34nm-based SSDs with a capacity of for example 120GB will be sold as a 115GB 25nm-based device.
Corsair reports a relatively small reduction (3 to 4 per cent) in performance when benchmark testing the 25 nm-based Force series. All of the new Force-series devices will have a “A” suffix to assigned to its model name, i.e., the Corsair Force F120 becomes Force F115-A.
