The storage that I know

As we all know, storage devices are the media that holds data, including tapes, CDs, videotapes, floppy disks, USB drives, hard disks, arrays, and so on. Here's what I'm talking about from the storage I'm touching:

1, primary and secondary school period, 90 's, 2000 years or so, the most contact is tape and CD-ROM.

Tape, which is played through a tape recorder. At that time the most listened to is the following, hehe. Later, there was a repetition machine. The tape recorder retired, and put it at home for mom and dad listening to music ~

　　　　

2. CD-ROM

Black and white machine was eliminated, color TV gradually popularized, the CD-ROM began to popular, at that time a lot of home to the color TV set Vcd/dvd, you can put the disc to see. Of course, the most watched is the film. People are still using CDs, but not many. At present, the more common CD-ROM is the system disk, specially re-installed computer.

It is said that the 1958 invention of optical disc technology, until 1972, the first video CD.

3, U disk

The first time I heard this novelty is about high school, listen to my brother said, that little thing can save a lot of content, the teacher all the courseware can be stored inside, no longer worry about missing what knowledge points. But I haven't used it yet, but I've seen it before.

When I was in college, I used it a lot. As a software engineering professional children's paper, since the use of a U disk has been a amnesia, U disk always forget to unplug from the computer room, go out to find a U disk, and then forget that they have already unplugged the U disk, still looking for a U disk ...

Upgrading from 2G to 4G, 8G, 16G, to the later 32G, and then never bought a U disk, because the mobile hard disk was invented.

　　

The history of tracing the USB flash drive should be first published in 2000, when a total of 5 companies worldwide have their own flash drive brand sales, 5 mainly Israeli m-system, Singapore track, Netac USB, Lowen Ipan and South Korea's flashdriver. The true acquisition of the U Disk Basic invention patent is China Netac Company. But the first U-disk I used in 2010 was Kingston Kingston, and everyone said it was a good brand, about twenty or thirty bucks.

4. Mobile HDD

In other words, the first time to see the mobile drive is also the new equipment brother bought. Look at the thick and big, the capacity seems to be 500G (it may not be so big), it will feel very big. After connecting with the laptop, there is a slight vibration at work. It looks something like this.

　　　

Sophomore or junior year, also about 12, see a classmate of this professional bought a very lightweight mobile hard disk, only know the original hard drive and tall on. and brother that big black ratio, classmate's small white obviously more attractive ah ~

The above is just I know the time of the mobile hard disk, in fact, people come out of the time than I know it time to early. It is said that the country's first mobile hard drive was listed in 2000. Http://m.zol.com.cn/article/1338977.html?via=index
