Very bad 4K read speed with Sandisk SSD Plus 240GB, any idea why?
I replace the harddisk with Sandisk SSD Plus 240GB which I bought few days ago in my old samsung notebook NP350V5C. The notebook is running windows 10 Home 64 Bits version and the SSD is running in SATA 3. I have tried to use the Microsoft chipset driver, turn off the Windows Write-Cache Buffer Flushing, run windows safe mode, run in high performance mode, check partitions are correctly aligned. The CrystalDiskMark score pic is attached. Any idea why the 4K read speed is so low? Thanks.
