Intel 660p 2Tb Nvme help!

[AVlad4]

Please specify what is the established linear recording rate for this model after using the SLC cache.

For 1Tb model, it is about 100mb.

What is it for 2TB model?

Saw the screenshot that the speed is 245MB

Hello AVlad4, Thank you for your reply. • We followed the Evaluation Guide for Intel® SSD 660p Series (https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/consumer-ssds/Intel_SSD...) and the results were similar to the ones shared on the previous chart. Please take into consideration that those results were accomplished on a controlled environment and using the recommended benchmark tools as specified in the article, if you experience any difference in performance after following the guide in a similar or the same environment please let us know the results. • Regarding your second questions the usage of any third party adapter in order to connect your M.2 SSDs to a PCI-e is not tested, supported or validated by Intel® and we advise you to contact the OEM of the adapter and your motherboard to check compatibility and hardware support. We hope you find this information helpful. If you have future questions, please don’t hesitate to contact us. We will be more than happy to help you in any way we can. Have a nice day.

I watched a lot of reviews. And in all of them the steady speed in the region of 75-100mb for the model 500GB and 1TB was determined. And I was hoping that here me would help me to get the same data but about the 2Tb model. It's just because SLC is exhausted after about 1.5-2 minutes of copying. But I do not have a ssd to check it out! And to buy, I wanted to clarify

Hello AVlad4, Thank you for your reply. Some information that is available online can be misleading and confusing when it comes to benchmarking an SSD. The Evaluation Guide for Intel® SSD 660p Series (https://www.intel.com/content/dam/support/us/en/documents/memory-and-storage/consumer-ssds/Intel_SSD...) is an official and reliable source of information. Another option is to check https://ark.intel.com/content/www/us/en/ark/products/149403/intel-ssd-660p-series-2-0tb-m-2-80mm-pci... for performance and reliability information. Please, take into consideration that some traditional benchmarks and tests may involve pre-filling the SSD with data, and immediately followed by further writes to evaluate performance. Although it is a good way to stress the SSD to understand its characteristics, the testing methodology may not reflect the actual use case scenarios. Intel recommends that sufficient idle times be given, to mimic the common PC usages, especially on tests that expect a heavy pre-fill condition. The idle time, will refresh the SLC cache by transferring the data into available QLC media and will ensure a better user experience. We would like to know if you need further assistance or if we can close this case. If you need further assistance please do not hesitate to contact us. Best regards, Josh B.

I have the impression that you do not understand what I am asking.

 I want to know to what level the write speed drops to disk when the SLC cache is full. And that's it!

Here, for example, another reference to a similar test.

http://www.thessdreview.com/featured/intel-ssd-660p-m-2-nvme-ssd-review-1tb/6/

Cache overflow is pretty quick. And the speed drops to 100mb.s (but there is a lot of such data only for the 1Tb model)

That's what I want to know for the model 2TB! Do you understand?

This is a very important parameter that is not given in the documentation, but it will directly affect the transfer of large amounts of data.
