Which SSD M.2 NVME to use for plotting?

I have just looked at 3 NVME M.2 Gen 4 SSDs. Which one shall I buy? I have read that Corsair doesn’t work properly on longterm reading and writing. Samsung has a low TBW. And from another thread about another version of Seagate SSD ( Barracuda) there was apparently a problem.

Hi guys, I’m having terrible problems with how slow this NVME is. When I run a plots on 2TB nvme barracuda, 1tb nvme Samsung evo, and on spare new 18tb HDD( for test purposes) I’m getting very strange results. Seagate nvme is slowest from the 3. For example from plot logs: When computing table 1: Seagate NVME: F1 complete, time 776.407 seconds; Samsung Evo : F1 complete, time 106 seconds; Sata HDD: F1 complete, time 146 seconds; Another example: after plotting for 1h40min: Seagate: 6% …

I don’t think there is a right or wrong answer here, you need to look at the numbers and decide what you want…

these read/write speeds are correct for the first short burst, then they drop off like crazy, hence why they are so slow.

Rocket (not the plus one) are pick of the bunch for me, high sustained, good TBW, no SLC. You can get a P5510 for roughly the same price as 2 rockets but not sure how it compares vs temp1/2 on rockets.
