Post: Some information about the NAND.

(adsbygoogle = window.adsbygoogle || []).push({}); Well here is some information for people that don't know what the NAND is, or what it does.

- 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.

if we took out the nand in the ps3, got some special device, coyuld we read ad potenially write the nand.

Nothing stops you from ever reading/writing to a memory device. But the information is encrypted on it.

What shiver said. Unless you Decrypt, or corrupt it.

You corrupt it, the PS3 will never boot again.

BLAH.. we already knew what NAND flash was.. LOL thats newbie firmware knowledge
