    hello

    I have a 250GB Samsung 850 EVO (SATA6Gbps) which I have had for about 4 years, during this time it has had 40TB of writes (75% were within the first 2 years - optimized it 2 years ago and reduced writes by approx 75% - mostly through disabling hibernate and using a portable Opera browser in a RAM drive), the drives 4K and IOPS performance is severely hampered, up until recently I used to get an AS SSD score of 1080 and now scores 600

    The system is fully SSD optimized following Samsung Magician instructions for the most part, HIBS and Win10 Telemetry disabled, Windows Search/prefetch is disabled, Indexing and compression is disabled.

    My SSD is only about 30% full, it has 10% set aside for Over-Provisioning and I run Windows 10 on a Quad-Core i5 (Ivy Bridge) with 12GB RAM (RAPID off), I have tried forcing TRIM and various tools and even new/old/3rd party AHCI/IaStor drivers which yield the same results?

    The SSDlife Pro program reports no issues and excellent health - with a life expectancy of another 8 years, SMART data is below

    Should I start looking for a new SSD?

    also, what is the current 'go-to' SSD brand/model? is it still Samsung Pro..?

    thanks in advance
