G.Skill Jumps on 25nm Bandwagon
G.Skill has unveiled an upgraded Phoenix EVO SandForce-based SSD with (SF-1222) controller, based on 25nm NAND flash. Just like the shrunk version of Corsair’s Force series, the new unit has a usable storage capacity of 115GB instead of 120GB due to overprovisioning to compensate for the reduced endurance of 25nm NAND.
Write performance remains at 270 MB/s, and sequential reads 280 MB/s, but IOPS values have not been announced, likely because G.Skill’s drives have had some problems competing in this area in the past.
The production of solid state drives in the 2xnm process will result in reduced cost. The new unit is scheduled for early April, so it should be available any day now.

Actual maximum capacity (without reserved areas) – 128GB, (128-115)/128 = 10.15% is reserved.
Comment made on April 8th, 2011 at 8:50 amThe actual total maximum writing endurance is 100%*3000/5000 = 60% of the previous generation NAND SSD. In other words, to get the same write capacity as the previous generation SSD, you would have to purchase a “new” SSD of such kind with the total capacity of (128/0.6)*(1-0.1015) = ~ 192 GB, instead of 115 GB.
