"The new SanDisk Extreme Pro Series of SSDs feature the same controller as the Extreme II, albeit with updated firmware, slightly higher clock speeds and new 64Gbit 19nm MLC NAND. As such, their specifications have been bumped slightly as well as seeing a huge increase in the warranty length that’s been jacked up to 10 full years! Though curiously, the drive endurance rating remains the same at 80 TBW for which they are probably counting on most consumers to upgrade well before the 10 years. They’ve also dropped the 120GB version available in the Extreme II line and now offer only 240GB, 480GB and 960GB versions. Part of this is because the 120GB versions just don’t see the same performance as the larger drives and the second part is that SSD prices have dropped enough that the 240GB drives are now in the market sweet spot. The performance piece is key as these drives are targeted to gamers, PC enthusiasts and media professionals for which most are probably looking for 240GB drives at a minimum."
