I actually had a huge upgrade in install speeds on the original LCD by going with a 1TB SSD. The OLED was different because the included SSD was faster.
Thing is, that doesn’t mean much when, as other people have said, the Deck is limited to PCIe 3. So it comes down to power efficiency and price. Right now, Best Buy is selling the WD SN770M for ~$160, and that’s your best bet.
So, it works pretty well as far as the refresh rate is concerned.
But woo lord, it shifts the gamma entirely too much for me. But so far, it’s pretty awesome for messing with things - thank you!
