It also includes Samsung's excellent Magician software, which we've covered many times previously. The 4TB SSD 850 EVO still includes a five-year warranty, like the other capacities, which is the longest of its class, as most "value" drives include only three years of coverage. That's the usual order of things as you go up an SSD maker's stack. It's just odd that the rating didn't change, given the fact that the drive has twice as much NAND flash. For what it's worth, 300TB is more than a typical end user, under ordinary workloads, will ever write to a drive in a lifetime, so it's not a major concern. It's a decent step up from the lower-capacity drives, though it is surprising that we didn't see an increase in endurance when doubling the capacity from 2TB to 4TB. That is four times what the 120GB and 250GB drives are capable of, and double what the 500GB and 1TB drives offer. At both capacities, the drives are rated to be able to write up to 300TB of data. Surprisingly, one specification that the 4TB drive shares with the 2TB model is write-endurance. Some of the other specs (such as random read and write speeds) vary according to capacity, but not by much. What this means: Currently, all of the Samsung SSD 850 EVO drives have the same specs in terms of sequential reads and writes, 540MB per second and 520MB per second, respectively. (More chunks of memory allow for increased parallelism.) But in the case of the Samsung SSD 850 EVO, it seems like it was already as fast as the SATA interface previously allowed.

This performance-claim flatline is a teeny bit surprising, given that SSDs in a given family typically perform better as the capacity increases, all else being equal. (The 2TB drive had 2GB of DRAM cache.) Despite the audacious boost in capacity, the rated performance specs for this drive remain unchanged from the previous capacities.

(The 1TB and smaller drives used a different controller.) But it now has a staggering 4GB of DRAM cache, plus new firmware. This new model recycles a lot of the parts from the 2TB model, including its MHX controller and PCB. However, Samsung is now producing third-generation, higher-capacity 48-layer NAND, and thus the 4TB SSD 850 EVO was born. It used this technology for all of the original capacities of the SSD 850 EVO (120GB, 250GB, 500GB, and 1TB), as well as the 2TB version that came later. When the SSD 850 EVO launched back in 2014, Samsung was using its second generation of 3D V-NAND, which had 32 layers. This allowed Samsung to make its flash chips physically larger on SSD circuit boards and just pile up the NANDs instead. So Samsung, followed later by other flash-memory manufacturers, created a NAND die with multiple vertical layers, stacked one atop another. After all, you can make areas that hold data only so small before you begin to run into limitations. That was all fine and dandy for a few years, but as the memory cells were continually reduced in size to increase capacity (packing in more using increasingly advanced manufacturing processes), performance became an issue, as did endurance. If you're just catching up with that stuff, prior to the SSD 850 EVO series, SSDs used NAND flash that was laid down in a single flat plane.
