I'm updating my rig this year and am considering updating the m.2 drive that I currently have, which is a 256GB Samsung 960.

Questions:
  • What's PCI-E 4.0 drives bringing to the table if used for an OS drive?
  • What's the best drive to pick up for OS - say 250GB or thereabouts?
 
no idea what said:
Until now the difference for the majority of people isn't noticeable, especially when gaming.

But with the upcoming RTX3xxx cards coming with direct ssd access, some lightning fast ssd storage could make a significant difference. We won't know until reviews and resting is allowed though.

I assume that would mean having the game installed on the Gen 4 SSD and not just running Windows on it? Sorry for the no0b question, it's just a significant point IMO as it would dictate the storage capacity required.
 
I've got a MSI X570 Tomahawk with a Samsung 950 Pro in the M.2 slot 1 (CPU) being used as the OS drive. Would it make a difference if I plugged the new Gen 4 drive into M.2 slot 2 (PCH) to use as a gaming drive, or would I need to be in slot 1 for fastest speed?
 
The chipset fan is a good point, but unavoidable if I'm to make use of the second M.2 slot for any reason. It actually isn't an issue for me personally because the PC is in my garage and I'm not, so I don't hear anything - unless you meant it could wear the fan out?
 
I picked up a Corsair MP600. Here's benchmarks compared to my Samsung 960 EVO.

I've moved some games to the Gen 4 drive that were slow loaders on my SSD and I have to say they seem to take just as long i.e. no improvement. I'm hoping the upcoming IO technology from Nvidia will reap some reward coupled with my 3080. :)

Summary is that the Gen 4 appears to be twice as fast as the Gen 3.
