Obviously there's always a customer for faster speeds, but have we even hit the upper threshold of PCIe 4 in the consumer market?

- wtallis 5y agoThe first wave of consumer gen4 SSDs that all used the Phison E16 controller were only good for about 5 GB/s out of the ~7 GB/s possible (and 3.5 GB/s on PCIe gen3). But the newer gen4 consumer drives that started hitting the market last fall come a lot closer, and this summer a lot of those are getting refreshed with newer, faster NAND that will have PCIe 4.0 as thoroughly saturated as PCIe 3.0 has been for the past few years. Phison has already clearly stated that their next high-end controller after the recently-launched E18 will be a PCIe gen5 chip, and the E18 is fast enough to finish out the gen4 era.
- dstaley 5y agoAbsolutely wild that PCIe 4.0 was saturated just two years after introduction in the consumer market.
