Samsung 990 pro vs Crucial P510

On a gen 1 t14 what you pick is irrelevant. Get the cheapest thing possible.
FWIW the only metric that really matters is 4k random io without queue depth. If it’s anywhere near what the modern drives offer it’ll be fine regardless of pcie generation.
Doesn’t matter one bit if you’re running a 14000MB/s drive vs a 500MB/s drive. The 4k io is sitting under 200MB/s for all nvme options I know of in the consumer world.
Between those two devices, get the Samsung, after you get it installed just run their Magician software and make sure it’s on the latest firmware and you’ll be fine on that data issue.
