Such measurements could indirectly provide some insight into the condition of the controller.
The "AKE" chip appears to consist of 5 switchmode step-down regulators plus 1 boost regulator. I couldn't find an off-the-shelf part that matches its function or pinout, but, FWIW, the following Power Management IC (PMIC) might help to understand how these chips work.
LM10692/LM10692B, Texas Instruments, Power Management Unit for SandForce SF3700 SSD Controllers, 6 buck regulators, I2C:

9.2.1 Design Requirements
The application needs to be able to operate with the default output voltages. Output voltages can be changed through I2C after start-up but the power-up levels will always be the default values.
ISTM that any significant difference between the OP's and sourcerer's voltage measurements might suggest that the controller and "AKE" chip were not communicating. Assuming any voltage difference was still within the operating range of the SSD, then the controller would be suspect.
