Probably not the right community for this, but I've been searching for a new 2TB SSD for my Thinkpad T14 G1, It's only PCIe gen 3.0, so both are going to be limited by that anyway. I specifically need resonably fast sustained write speeds, and both of these can write at >1GB/s for 15 minutes. The Samsung seems to be the better choice, but I remember them having some data loss issues a while back and that is worrying me, and the P510 is quite new, so not much time for any issues to be found. I can get both of them for the exact same price, which of these is the better pick? The P510 also seems to use a bit more power, so maybe not a good idea for a laptop?

EDIT: Thanks for the help, ended up getting the Samsung 990 pro

The Samsung has DRAM-cache. Better performance on write speeds and less wear.

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.
