Summary Comes with a heatsink that fits the PS5, but can still run hot under sustained load. Has used TLC or QLC flash depending on size and batch, so long writes on some drives can slow sharply. Also varies between TLC and QLC flash, so long writes on some drives can slow sharply. Not available Pairs the US75's controller with the XS70's heatsink design.
