ATTO benchmark shows that the 3rd and newest disc reaches the speed it should.
I never realised the results could be so different in two "recommended" benchmark programs
Corsair drives use a SandForce controller. SandForce based drives work best when the data they are using can be compressed.
ATTO uses "best-case" scenario data. AS-SSD uses "worst-case" scenario data. Real-world data is probably in the middle.
Manufacturers like to advertise using best-case data.
As a side-questions:
When transfering files in Windows you get this pop-up-window with the current speed of the transfer. How accurate is that?
I would assume it's very accurate since "real-world" data is being used.
