Advertised speeds for your drive are with ATTO benchmark software, not AS-SSD or CrystalDiskMark.
ATTO uses compressible data to test Read/Write speeds.
AS-SSD & CrystalDiskMark use incompressible data to test Read/Write speeds.
With incompressible data you will always have lower test results.
I would also "Log off" overnight if I were you to allow GC (Garbage Collection) to recover drive performance.
Your CrystalDiskMark settings indicate that you wrote 36GB on that 1 test run; and running AS-SSD you wrote an additional 5GB on that 1 run. Hopefully you ran each benchmark only once
