- NAND flash based mass-storage devices pretend to behave like hard drives. But actually it's just a simulation. TRUE hard drives can be written in units of 512 bytes, called "sectors."
- NAND flash is both readable, and writeable.
- Unlike hard drives, the fundamental read/write unit is a "page" NOT a sector. Older sectors from 2007-2008 have a 2k page size. Newer ones have a 4k size.
- Heres the typical block sizes:
32 pages of 512+16 bytes each for a block size of 16 KB
64 pages of 2,048+64 bytes each for a block size of 128 KB
64 pages of 4,096+128 bytes each for a block size of 256 KB
128 pages of 4,096+128 bytes each for a block size of 512 KB
- Nand can be replaced with hard drives.
Theres ALOT more information I could include, which I will overtime. But for now, here's some of the basics.
BLAH.. we already knew what NAND flash was.. LOL thats newbie firmware knowledge
