Along with Al's review of the new EVO line you can get a second opinion from The Tech Report about the performance of the new SSD with a fast cache.  The majority of the storage is 19nm TLC NAND but there is an SLC cache sitting between the controller and that long term TLC storage to help with the overall responsiveness of the drive, aka TurboWrite. In the 120 and 250GB models that cache is 3GB while in the larger models you get a 6GB cache.  In their real world testing the new EVO drive is incredible at large file copying though Sandforce drives can beat it in small file copy speeds, likely thanks to the compressed write trickery that controller family is so good at.  Check out the review here and keep your fingers crossed that MSRP is the acual price these drives sell at.

Funny how these things can change your thinking about future machines. Suddenly I'm feeling like 1TB is the sweet spot for SSDs... :-)

at these (suggested) prices, hell ya!  I've paid more per MB on HDDs and bragged happily about it. 

 

Yes, I mean MB.

TLC flash + short warranty= they know it wont last very long but when it fails the warranty will be over and it is no longer their problem.
