pen drive.....IT age technology

I still remember during secondary school, I used 5" disk to save data. The disks performance very poor, low dense disk, save data had to wait long long time. Life also short, easy to bend and break. This is the first time I used disk. After graduate and work, the market came out with 3.5" disk which is much better and smaller thank 5"disk. IT age, the technology change so fast, now a day pen drive is used to save data. It can save up to 32GB and durable last longer life. If you are software or IT executive, you can save programme in one pen drive. Not like 3.5"disk have to save untill 20 pieces. difficult to carry, have to insert one by one when install programme. With pen drive, once plug in, can install fast. Pend drive easy to carry, put in your pocket. it also can tie together with the mobile phone string or name tag's string. The price also reasonable, have many brand, color and pattern on pen drive. pen drive help alot in my job. i would like to thank the person who invent this pen drive. i will invite him for a drink, but i dont know who is this person. did you know who is him???
