Corsair claims 25nm Flash ICs not as reliable as 34nm
 

ANYONE INTERESTED IN getting a SSD have been looking forward to more affordable 2Xnm Flash memory as it's been promising lower prices for consumers for the same size drives, but now it seems like things might not be as rosy as first thought, at least not if Corsair is right. The company has posted a long statement on its blog explaining the difference between 34nm Flash and 25nm Flash and it suggests that the newer 25nm ICs aren't as reliable as the older 34nm ICs.

It's not as if it'll matter hugely though and some of this depends on the SSD controllers if we're reading things right, which seems quite odd. The first two 25nm SSDs from Corsair will be the F80-A and F115-A where the “-A” denotes a SSD using 25nm ICs. The F115-A replaces the F120, so in other words, the new drives will offer less storage space, albeit at a lower price as Corsair's MSRP of the F115-A is about $15 cheaper than that of the F120. However, some smaller models might actually end up costing more due to the extra overprovisioning.
