Battery drain from external SSD during sleep in MBP occurs due to unexpected power usage.
You're experiencing issues with your Samsung T1 SSD and MBP setup. The periodic lighting of the SSD even when the system is off might be contributing to battery drain. Checking Energy Saver settings to put HD to sleep and disabling wake-on-WIFI and power nap features seems correct, but the persistent activity could still be a factor. Consider testing with different power management configurations or consulting Samsung support for deeper diagnostics.
