Vigile (99919) writes "As SSD controllers continue to evolve, so does the world of flash memory. With the release of the Samsung 850 Pro SSD announced today, Samsung is the first company to introduce 3D NAND technology to the consumer. By using 30nm process technology that might seem dated in some applications, Samsung has been reliably able to stack lithography and essentially "tunnel holes" in the silicon while coating the inside with the material necessary to hold a charge. The VNAND being used with the Samsung 850 Pro is now 32 layers deep, and though it lowers the total capacity per die, it allows Samsung to lower manufacturer costs with more usable die per wafer. This results in more sustainable and reliable performance as well as a longer life span, allowing Samsung to offer a 10 year warranty on the new drives. PC Perspective has a full review with performance results and usage over time that shows Samsung's innovation is leading the pack."
