Samsung releases 3D solid state drive

story imageAnandtech reviewed the Samsung 850 Pro SSD that features a new 3D storage structure.
For years it has been known that the scalability of traditional NAND is coming to an end. Every die shrink has been more difficult than the previous as the endurance and performance have decreased with every node, making it less and less efficient to scale the size down.

By stacking transistors (i.e. cells when speaking about NAND) vertically, Samsung is able to relax the process node back to a much more convenient 40nm. When there are 32 cells on top of each other, it is obvious that there is no need for a 10nm-class node because the stacking increases the density, allowing production costs to scale lower. As we have seen with the history of NAND die shrinks, a higher process node provides more endurance and higher performance, which is what the 850 Pro and V-NAND is all about.
Although launching with a slight cost premium over traditional NAND, the benchmarks show that this drive is "without a doubt the best drive in the market" and the future of solid state drives.

So...when your spinning disk motor breaks how do you plan on recovering your data? Oh, backups? Cool, did you know that backups work just as well with SSDs?
