the 3mb EEPROM (Electrically-Erasable Programmable Read-Only Memory) is nothing like a "bootable thumb drive". thumb drives use FLASH MEMORY which is based on EEPROM, but unlike EEPROM can be rewritten and reprogrammed an unlimited number of times.
For something to be written on an EEPROM, any data existent has to be erased, it also has to be written bit by bit.
again this differs from a FLASH MEMORY where data is written block by block and existent data does not need to be erased.
unless we use SSD drives as our hard drives, which i guess most of us don't, then the 256 mb FLASH MEMORY on the rover is, again, nothing like our hard drives, except in the sense that it stores data...
for a senior engineer that worked 24 years at NASA you sure make very vague comparisons between existing technology.

Sorry about the teaser ending. I might as well have a little fun, and it was the best place to break. I'll try to post the next block within 24 hours.

Hrm. Hate to be pedantic, but flash memory is a type of EEPROM, not an alternative storage strategy. Whether or not you use something like flash has to do with how much write load you anticipate and other performance quantifications. So, to be very blunt, EEPROM is not just like a thumb drive, a thumb drive is an EEPROM implementation in every case I am aware of. A specialized one, certainly, but still. I respect your Wiki-fu but suspect you aren't truly an expert in this area. Pardon me if I've insulted you, it's not my goal. Just trying to illuminate.
If I were trying to explain a computing concept to a layman my analogies would leave a lot to be desired for an audience of computer scientists or engineers. The deeper your precision the less approachable your presentation to the unspecialized.

Not like its offensive to be having a hand at fooling the entire audience of this site for "a bit of fun".

Hey jerk, first of all there are only 2 threads that this guy has written. One of the being a freakin' introductory post. Where he even stated that there isn't a conspiracy to prove here, that he is awakening to realize that NASA is not a transparent organization.
