| 11. Why actual capacity is lower than label marked? |
| The capacity won't be less than about 93% of on label after formated, which USB Flash Drive products are good.
For the capacity loss in normally, between Flash formatted and unformatted.
Here's example to a Hard Disk (same theory to NandFalsh):
Hard disk original capacity 80GB the trade mark is showed 80GB on it. 80GB→ 80?000 = 80,000MB→ 80,000?000 = 80,000,000KB→ 80,000,000?000 = 80,000,000,000 bit. when the hard disk 80GB is formatted, it possesses 80,000,000,000 bit , original capacity is to be marked 80GB too, but it is switched in windows system: 80,000,000,000 bit→ 80,000,000,000?024 = 78,125,000KB→ 78,125,000?024 = 76,294MB→ 76,294?024 = 74.5GB This is cause the capacity is deducted ,it is from converted unit 1000 and 1024.
Every flash memory products, include hard disk products have the same characters like this. |

| 15. What is upgraded chip? |
| The worst quality chip materials are might software modified chips.
Which are low capacity, but appeared in large capacity on the computer.
For example, the actual capacity is 64MB, the dishonest factory wrote a control software inside of the USB Drive,
when put this upgraded USB Flash Drive on a computer, it will be appeared at 2GB, when you copy 2GB file to this
USB Drive, even it's no problem on this company. But when take it out from this computer and test it on another computer,
the 2GB file will not be opened successfully. It made a terrible shelter, which would cheat most buyers.
This kind of material was called upgraded chip. Go to top |
