Have you removed IC1 to see if the short goes away? In any case, even if the short persists after removing IC1, you could then power up the SSD and examine the other supplies. It seems strange to me that there are two 3.0V LDO regulators ("HJ", TLV70730), if indeed that is what they are.
Here is a review of the 1TB version of this SSD:

The SSD is populated on both sides, so one wonders how the two 3.0V regulators share the load, assuming they power the NAND Vcc.
The SDRAM is a 1.35V IC which can run at 1.5V.

This makes me wonder whether the NAND I/O is also running at 1.5V, but I can't locate its I/O voltage spec.
