Some questions for 25nm IMFT NAND flash

First let me introduce, my name is Jan Černý and I work as SSD reviewer for Czech web magazine: http://extrahardware.cnews.cz/ (in the past I working for http://pctuning.tyden.cz/hardware/30)

In these days I working on Kingston HyperX SSD review.

This SSD have Intel 29F16B08CCME2 NAND flash chips. This document says:

• 25nm MLC Intel
• ONFi v2.2
• 2 die, 2 CE, 2 R/B, common I/O
• 5000 Program/Erase cycles
• asynchronous mode only

But local PR:

after speaking also to R&D we don't give out those specifics. I can tell u that it is synchronous NAND w. 5000PE cycle endurance - everything else is internal only.

Intel SSD 320 have 29F16B08CCME1 and Anand says: http://bit.ly/r3yy9f

ONFi v2.1
asynchronous mode only

Which information is correct? It's only different version (1=synchronous; 2=synchronous)?
