Toshiba have made this amazing 0.85-inch 4GB HDD. Looking at the pictures below you will be amazed at how something so small can be made.
The drive is slightly larger then a stamp and would be ideal for cameras, phones, MP3 players as well as card readers where transporting data around would be made far easier. I can see this device from Toshiba doing really well!
HI THERE YOU COULD BE RIGHT BUT THEN AGAIN MOVING PARTS COULD HAVE HARD DRIVE FAILURE BUT I COULD SEE DEVICES WITH A SWITCH IF HARD DRIVE FAILS YOU CAN SWITCH TOO FLASH STORAGE MIGHT BE A OPTION
