Running Adata S510 120 GB SSD on Win 7, Lenovo T420 laptop, here is what I've verified/tried:
Latest SSD firmware Latest Lenovo chipset drivers Updated/Switched to Intel RST drivers (no change) Verified TRIM enabled Disabled caching Verified AHCI is enabled in BIOS and in Windows Verified its SATA III Changed power profile to max performance Disabled Defrag schedule ATTO has similar results
I have done every major step that I can find, it seems everyone with this poor of benchmarks are running in SATA 1 or SATA 2, or have their TRIM disabled or don't have AHCI enabled. Not me.
