Tldr; 14,9 GB/s read 14,0 GB/s write

How many seconds at that speed until it throttles though?

The thing that is always painfully missing from any benchmark, is an endurance test.

I want to know how many TB I can write consecutively before the disk starts to degrade in performance and stop being useful. So far the only way I have been able to achieve this is to purchase a couple of every disk and stress them until failure, logging that interval, and selecting the winners for usage.

I do not care about how fast it can write over the course of five minutes, I want to know how fast it can write over the course of five hours continuous usage.

AFAIK, some sort of endurance metrics are provided in the specification sheet. Although the exact metric can vary by manufacturer from what I remember.

Many but not all will have a 'total TBW' metric, but that is more of a 'how many write cycles can this theoretically last' metric. What I am predominantly interested in is "how many TB can be written before sporadic write delays start occurring"

So how long does it last?
