its alot smaller than a hard drive lighter and has no moving parts like a hard drive, but can store more than some hard drives if so why not make hard drives like flash disks but bigger then we could have tones of space talking in tera bytes?

A USB Flash drive is made up NAND gate circuitry based Flash Memory (a form of EEPROM ) integrated with USB-1.1 & 2.0 interface. A flash drive derives the power for its operation from the host USB Port. This was invented by IBM in 1998 as a replacement for floppy drives in their Thinkpad Line of products but they never patented it.

Not so!
The largest of USB flash drives are around 2 GB. Hard drives left that size behind (as a maximum size) nearly a decade ago. The smalest hard drive you're likely to encounter today is 40 GB. It would take 500 2 GB USB flash drives to equal 1 terabyte of storage space and would be the size of a good-sized tower PC or server. At current prices, it would cost over $50,000.00
Flash drives are actually slower than most hard drives.
Flash memory has a finite limit to the number of read/write cycles it will support before failing. Older flash memory was as low as 100,000 read/write cycles. Current flash memory is about 1,000,000 read/write cycles. A mass storage device using flash memory in the manner of a hard drive would wear out in a few months.
We should see single spindle (SATA) hard drives of 1 TB capacity sometime during 2007. A thumb-sized flash unit with that capacity is many years away.
Flash drives have their place, but it won't be as a substiture for the traditional hard drive any time soon. If ever.

many reasons .
Security
Transfer rate
Redundancy
Expense
Capacity
etc..
