Hey, remember me ?
I posted about some entreprise SSDs here before, and now I made a full blog post about their insides! With even more pictures!
I hope you enjoy it :)
Yes, some chips (or rather parts of all chips) are spare on enterprise SSDs. You can even see how much is left via smart data

Crikey. I have to wonder what that ~2TB unit must have cost in 2016.
Interesting that the one has such large capacitors in it. I imagine that is as last-ditch effort to keep the board powered long enough to finish flushing all of its caches in the event of a power failure.

That’s exactly the point of power loss protection (aka PLP.) As a side effect of not needing to wait for a flush after a write synchronous write workloads are dramatically faster on enterprise drives with PLP.

I don’t even want to think about prices ahah, I could have done some research and talked about it on the article tho…
And yeah that is probably why

I can only conjecture it must have cost a mint.
