Why Sandisk Brand NAme (Icon ) is Scratch?

Lests To Undrstand Step By Step

Example :Tishiba or sandsik make Nand Flash (TC58nvg6d2ja20)

Before Sale to Market Must Be Tested By (FC or ROHS Standad)
some Nand Have Problem «BadBlock Over Normal Or LitoGraphic Problem»

so Tohiba and sandisk Never Destroyed the bad nand They Scratch Brand Name And sale to Black Marketing as low price

Example 2:

Orginal tc58nvg6D2jta00 orginal toshiba brand is 12~yuan

downgraded tc58nvg6D2jta00 is 3~4 Yuan

80 % Flash Memory Price Is nand

downgraded in Smi

Also SMi HAve A normal Program= SmXXtest.exe (you see in tester debug)«V 2.5.31» or «2.5.18» or «2.5.36»

and Dyna Downgraded Tool you see in tester debug date «131023» or othere date


in Alcor Downgraded Flash Firmware Version is «FF00» Force Firmware (capacity Mode )

in Phison XX.XX.10 is normal MLC XX.XX.30 is downgrade MLC

note 2:

Apacer CoB Normal Flash

2251-68 + toshiba A19 MLC normal nand firmware =1.02.10 Read Speed :23 Write Speed is 13 (Speed Optimize )

Philips 8GB

2251-68 +Toshiba Downgraded A19 6d2DDk A19 19NM Firmware 1.02.30 Read is :17 Write is «7» (Capacity Optimize )

Downgraded Nand Cant Firmware By Speed Optimize because havent well quality
