The Silicon Power XS70 drive does perform great versus other models we have tested in the past thanks to the Phison E18 controller coupled with Micron’s 176-layer 3D TLC NAND. We could write lots of data continuously before SLC cache has been fully occupied and even then, the drive remained at very acceptable write speeds. The incorporated heatsink does help with delaying the heating up process till the drive reaches about 73 degrees Celsius, a maximum temperature we have seen other drives reaching with much smaller cooling systems, but those reached it considerably faster.
