Could these additional flash memories be backups of cached data for data loss protection purposes?

The PCB appears to have data loss protection capacitors:

Just FYI, this thread contains dumps of the new WD firmware architecture:

6TB WD6001FSYZ-01SS7B1 PCB with 7 ROMs:

You need to know that recently (as an example charger, palmer, carmel....) all of those NEW families are 1024k ROM
that is how you know which one is which...

Now what is the use of the other 2, I really don`t know (sometimes NOTHING, similar to some SSDs i tried before)

I have a question, those PCBs so caled unlocked PCB, they originally unlocked or make them unlock?

Hello,
You Are Correct As you might have noticed that i saw 25Q40 eprom in 2 roms and 25Q80 in one so 25q80 is 1 mbit ,So this is rom for sure ,But i was wanting to know what other roms doo ,The Newer Drives From All brands are slowing increasing the complexity to work

ISTM that, if the extra memories contain cached data, you should satisfy yourself that there is no possibility to contaminate the patient's data with those from a donor. Therefore you shouldn't just dismiss them out of hand.
