M.2 ssd part identify?

[natsuu]

Hello does anyone know what this circled part of the ssd is? I just updated my laptop with this ssd and a small rubber thing slightly pushes against this part. Should I be concerned? Thanks in advance. The ssd is a WD SN750 4TB ssd

Is there a larger chip on the other side that's different to the two NAND modules on the left in the picture? If there isn't, this is the SSD's controller. If there is, this is DRAM (i.e. DDR3). It's fine to apply some pressure to it in both cases, but tbh what gets really hot is the controller, not so much the rest of it

Sorry I don't want to take the WD label off but this is what I see

it's fine, the label is soft and meant to fit surfaces that are not smooth

The small little metal package is the PMIC (power management integrated circuit). There must be four NAND packages at 4TB - 16DP (16 die packages) at 512Gb/64GiB BiCS3 with 64 dies required. Should also have 1-2GB of DRAM.

is it a problem if a rubber thing slightly pushes against that area?

At U36? That's next to the three capacitors, related to DC-DC conversion. You don't want shearing (lateral) pressure on this but there should be no issue of electrical conductivity.

its like a rectangular piece of rubber that pushes on that whole red part I circled, I think its a equivalent pressures of using your finger to lightly push something down. if that even makes sense lol. Sorry Idk how else to describe it

[NewMaxx]

Oops, I meant capacitors, sorry. Yeah it's a component for DC-DC conversion (U36) so it is necessary but it can take some vertical pressure.

worse case if it breaks, will i lose all my data?

[NewMaxx]

I mean, it's possible to get data back, but not inexpensively or without knowhow and tools. You don't want to be breaking components off. Sometimes you can get by without one but that isn't the case here...but I mean it is tough and soldered. You just want to avoid electrical conduction (not an issue in this case I believe) and shearing/lateral (sideways or twisting) movement. These drives are often subject to vertical pressure from thermal padding and such.
