Corsair Switches to 25nm in the Force Series

by: admin Sunday, February 27th, 2011

Corsair Force F115-ACorsair 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.

To retain the same maximum endurance, a 120Gb SSD (actually 128Gb ?) would have to be marked as ~80GB SSD, and definitely not 115 !

Perhaps the manufacturers are simply counting on the 25nm generation to provide “enough” endurance as not to be noticed by most users? At any rate, the hype and marketing tactics surrounding 25nm is a bit odd to say the least.

Probably they are hoping to increase the support costs (warranty and so on) and to increase the share of higher capacity SSDs while hoping that they won’t write much more information on higher capacity SSDs. Also, they are probably going to put more costs into dirty PR to silence the complaints from not very organized retail users. Of course, the increased expenses would be payed indirectly by the tricked customers (i.e. they are most likely going to sell the new products at higher price margin (the price is going to be above 60% of the previous generation)).
Example: the price of an older SSD is 200$, the price of the “new” one of the same capacity is not 120, but 160, about 30$ is put into dirty marketing methods, and 10$ of added profit is remaining. But from a more considerable consumer’s point of view any price higher than 120-130$ is UNFAIR.

(Even with older SSDs i faced multiple dirty marketing abuses when it came to problems related to lowered lifetime under higher workload.)

At present time, the reference price for Corsair F120 is 310 $ while Corsair F115 is 285 $, while in terms of reliability it would be worth buying ONLY at 186 $ (310*0.6) which means that now it is WAY OVERPRICED and DEFINITELY NOT WORTH BUYING !
