Why cant you find a 1TB Flash drive? And what are the differences in USB1.0 /USB2.0 / USB 3.0 Technologies?

What is USB 1.0?
It is basically the first standard definition of USB it supports a low speed rate of 1.5 Mbit/s. It is intended primarily to save cost in low-bandwidth human interface devices (HID) such as keyboards, mice, and joysticks.
What is USB 1.1?
It is the next generation of the USB Devices. It supports full speed rate of 12 Mbit/s. It is very similar to the previous standard except each bit transfer is 8 times faster. All USB hubs support full speed.
What is USB 2.0?
A hi-speed (USB 2.0) rate of 480 Mbit/s was introduced in 2001. All hi-speed devices are capable of falling back to full-speed operation if necessary; they are backward compatible. Connectors are identical to the original USB.
What is USB 3.0?
It boasts a much more higher data transfer bandwidth of SuperSpeed (USB 3.0) rate at 5.0 Gbit/s. The USB 3.0 specification was released by Intel and partners in August 2008. New devices supporting USB 3.0 is expected to be produced by the end of this year. The new connectors will be backward compatible but they will include a new wiring system to allow for full duplex communication.
You could build a terabyte flash drive from 32 each, 32 gigabyte CF cards. At $90 each, this is almost $3k.Why cant you find a 1TB Flash drive?

>What is USB 1.1?
.....speed rate of 12 Mbit/s. It is very similar to the previous standard except each bit transfer is 8 times faster..... ((All USB hubs support full speed?))
>What is USB 2.0?
.........hi-speed (USB 2.0) rate of 480 Mbit/s.......
>What is USB 3.0?
......data transfer bandwidth of SuperSpeed (USB 3.0) rate at 5.0 Gbit/s........full duplex communication.:
You can probably buy 1 TB flash drives, for 4-10k
Do you have any idea of the data density level even the highest capacity chips are doing now....
Usb is a serial bus to get higher bus speeds the solution is easy, use high clock rates... You can get 2TB external USB drives for around 150-200
then why did'nt they do it first!? USB 1.0 would have been much more faster right!!!? :Ospeeds the solution is easy, use high clock rates
