Kingston KC3000 2 TB Review - Faster Than Samsung 980 Pro
The Kingston KC3000 is built using the Phison E18 controller and Micron's best 176-layer TLC NAND flash. In our performance testing, the drive can beat the Samsung 980 Pro and is the fastest SSD we ever tested. It shares that performance throne with the WD Black SN850.

The Kingston KC3000 has 2000 GB of TLC cache. It can use almost all of it (1930 GB) in SLC mode for 1930/3 = 643 GB.
I keep wondering though. Isn't this writing to the NAND twice? Say I write 100 GB. First I consume 300 GB worth of NAND when writing in SLC mode. Then I consume 100 GB worth NAND in TLC mode. Of course, writing in SLC isn't nearly as harmful but it is somewhat harmful isn't it? We don't even get to choose if we are willing to let go of this SLC caching for better endurance.
@Chris_Ramseyer Can you offer some insights into how harmful (or harmless) SLC caching is to NAND endurance?
@W1zzard Can you offer some insights to this?
