Hello AVlad4,
Thank you for your patience.
We noticed that you have an open case with our advanced technical support department that is related to the same issue, we will continue to provide you with support on that case.
In order to provide the community with the same information provided to you on your original case, we will be posting here the same official response to your question, which is related to the Intel® SSD 660p Series performance:
“The Intel® SSD 660p is built using Intel® QLC technology with a large and faster dynamic SLC cache in the forefront to handle drive writes and boost the write performance. The data from the dynamic SLC is transferred to the QLC during drive idle times thereby keeping cache fresh to enhance user write experience. The 660p is architected and designed for common PC usage models such as web browsing, e-mails, productivity tasks – project reports and spreadsheets and limited photo and video edits/storage wherein the workloads are clustered in burst with significant idle times in between. For usage case scenarios outside of the common PC usages and once the drive reaches 75% full, there are chances that the write performance may be below 100 MB/s.”
We hope you find this information helpful.
Best regards,
Josh B.
