Ask HN: iPhone X Tear Down
If I want to destroy my iphone and take the drive. Where is the hard disk?
The step-by-step teardown at https://www.ifixit.com/Teardown/iPhone+X+Teardown/98975 shows that the Toshiba TSB3234X68354TWNA1 64 GB flash memory is on the outside of the logic board sandwich; step 12.
Though I think you'll be disappointed, that stuff is probably soldered on and can't be removed.
