Controller: Sandisk 20-8200162-3
Chip marking: D91030668-0326

I counted a total of 154 pins on this....Would the BGA-152 adapter work on this?

I'm not sure what that is, but definitely not BGA 152.

Ace?

It looks like some sort of eMMC. Sometimes Chinese manufacturers buy - and not-completely-working eMMC chips. They disabling CPU inside eMMC, and make it works like a common NAND chip. Maybe this is one of similar situation, when eMMC with turned-off controller, use external CPU on PCB. Reading data from this chip will be not easy - you will have to find pinout on default state interface, and use Spider Board or Circuit Board for reading data.

Also, you can try to detect pinout by yourself. The procedure is not so complicated - try to find controller on this drive PCB, then find pinout for this controller, and try to understand how pins from CPU are connected with pins on NAND chip (you can follow the small roads from controller contacts to NAND pins on PCB).

I have to treat this like a monolith?
Would the pin out be available on ace website?

Yes, that's right. You should solder it like monolith, with wires.
Pinout for this chip is not a property of ACELab development - it's open information that could be found in internet. We are not specified on pinouts for eMMC chips, but again - this information is open and not under NDA.

It is BGA-154 chip. It have 16-bit pinout. But sometimes need read it as 8-bit. I recover few cases with same chip. I have adapter too.

The client decided not to recover due to price but thanks for the info.
arvika, where did you get the adapter for it?

Rusolut.

Actually, BGA-154 chips are rare. So it's better to use the multifuncional solutions, than buy a single-chip adapter.
If you are advanced in soldering, you may solder and use the Circuit Board included in the PC-3000 Flash kit. If you want to save your time and recover data without soldering, you may use the universal Spider Board. Below you can see the target pinout:

How would you know how pins to connect?

You just arrange needles on Spider Board, and then - chose correct pin in software. For example - Needle number 1 - is a D0, Needle number 25 - is a ALE and so on.

Here is a link for Spider Board video with example. Pinout is different in video, but the main idea is the same.
