I had a broken ssd lying around and decided to open it up. I found these inside it. Is it some sort of battery or capacitor?

Bend it up so you can see the other side of it, it might have something on the other side to tell you what it is.
Those are Freedonium modules, just be careful to not have any oil in the close surroundings or it might trigger a reaction.

Looks to be some sort of capacitor according to google lens results
Looks like a flatpak electrolytic capacitor to me. Used so the drive can commit writes from volatile cache if it loses power – so you don’t have data loss.
Looks like capacitors.
They are used to store a tiny bit of back-up power so the SSD can still finish any pending write actions if power is lost.
That way your data doesn’t get lost/corrupted if your PC loses power unexpectedly.
>There are four capacitors on the rear of the drive which are used solely for data protection in the event of power loss where any information still in the cache completes its movement to the NAND even after the power is lost.

that’s where the magic smoke resides
Like others said they’re caps to keep data in the event of a power loss. It is funny they have the blue cover on them like that would stop anyone outside the US from copying it.
Forbidden candies.
Hey!is this some emc ssd you can’t force to 512byte by chance?looks similar to mine,200gb samsung mz3s9200hmdp,tried everything,still 520byte sectors…no sg3utils,no hdparm..i have 2…
Capacitor so that in the case of a power loss, any data that’s still in cache can complete its movement and isn’t lost.
Interesting, never knew some manufacturers put capacitors like this. What’s is the brand and model OP?

Just to give you some info on patents: this is kind of exactly opposite what a patent does. A patent is to publicly disclose a design and claim it as owned by someone, meaning that no one can copy it or use that design, whether knowingly or accidentally, without permission.
Why file a patent if you’re gonna hide the tech in the first place? All you’re asking is for someone to know “oh shit! There’s a patent, it’s easier for me to search the USPTO database than spend hours carefully disassembling this chip!”

it looks like those packets of individually wrapped butter
Is this a capacitor that lays flat?
Looks like a type of capacitor.
I read SSD as ass. Jesus, I’m tired, I thought you may be a Smuggler when I saw all those packets. I’m going to bed now
That’s a good quality drive to have sudden power loss capacitance to make sure data is written from temporary RAM to storage nand.
