Question: Why do they need to retrieve and destroy(dispose) the giftia?

It's only Episode 2.

I'm sure they'll explain what happens in a future episode.

Why do they need to retrieve and destroy(dispose) the giftia, instead of retrieve it, save the memory, insert it back to old giftia with new OS and send it back to the owner?

Even today, the most data we can store on a medium is 297 terabyte and this is an experimental optical disc that reads and writes even slower than old fashioned tape drives.

The human brain is said to room around 2.5 Petabytes which is 8-9 times as much, and reads/writes at near the speed of light.

It's obvious that data integrity would be a huge issue in an android made to mimic a human. Even with error-correcting flash based memory, we're looking at, with technology we can "see" the horizon of in the future, a maximum of 0,5TB per volumetric inch. So if they used 70% of the internal space of an android for JUST memory and memory controllers with such technology, (3D or even 4D NAND flash with ECC) it still wouldn't reach the capacity of the human brain or even half of that.

Unlike computer storage, brain storage is always written to as you can not turn off or pause your senses. Even in a computer environment where you CAN do these things, consumer flash tires out and dies within 10-20 years for a power user.

So, let's say for argument's sake that they could have half the capacity of a human brain in a giftia. (Memory lifespan of 40 years, error-free lifespan of 20 years) Then a big portion, maybe even half of THAT has to be overprovisioned (effectively back-up sectors that kick in when an active cell dies) and that leaves the error-free lifespan to 10 years.

So 9 years is plausible, with the best possible memory technology we know we can make in the future today.

Sidenote: there is biological as well as crystalline-based memory in research right now that is possibly going to double these estimates, but the timeline for that is impossible to predict and is very very far into the future.
