ASCII.jp Unexpected high -speed USB flash memory with a capacity of 1TB without thinking about how to use it

Until now, the USB memory, which has been collected a lot, had only 128GB classes.At one point, there was no fixed use, and the information came in the email news "HIDISC Toshiba 3D TLC equipped USB3.I bought a large -capacity USB memory with a long name called 1 flash memory 1TB.If you think about it, about 20 years ago, I felt that I was involved in the product planning of only 8MB USB memory named IBM USB Memory Key.

Extreme buying 1TB high -speed USB flash memory adopted by Toshiba 3D TLC NAND without thinking about how to use it

Many people who buy USB memory may sometimes feel questions, "What exactly do you buy?"Nowadays, if you look for a major online shopping, you can find only 16GB class products.If it is the best -selling capacity, the center of the market is around 64-128GB.

When I forcibly searched for a 16GB model, I found a product of 3899 yen for a set of 10 (10).And since the 1GB 10 -piece set sold by the same company is 3199 yen, the difference between 16GB and 1GB USB memory is 16 times, but the price difference is only 20 %.

By the way, it seems that the same company also sells a very small USB memory of a nostalgic "MB class" of 512MB.However, there is a proviso that "512MB, not 512GB", and it is quite interesting that some people buy it by mistake.By the way, the price for 10 bottles was surprisingly high, 2599 yen.

Even with the top selling 128GB, the actual selling price is about 2,000-6000 yen, and it seems like the distribution and manufacturing mechanism, the quality and generation of the memory elements used, the performance, and performance.The current situation is that amateurs do not understand at all.However, from the long experience of wasted use, it has been established somewhere in my brain that "there is a reason for cheap things."

This time, the author who bought the world's first USB memory (IBM USB memory key: 4800 yen at the time), which does not require a dedicated driver software 18 years ago, will also make the first 1TB USB memory in his life.I would like to introduce the story that I bought impulse in spinal reflex without a clear purpose.

Unlike the recent environment, which has a huge capacity of USB memory simply to the growth, expansion of the market, and lower prices, and that appear one after another, the appearance of the early USB memory is clear.There were reasons and purposes.

If you are a little interested in the memory elements and external storage devices of your computer from the past to the present, it will be a preaching to Buddha, but to hand over information to computers that do not have a common conversation language.From the past to the present, there were many physical media means.

Starting with a card in the 80 column that punches letters and numbers and holes the information, paper tape and various sizes can be replaced floppy disks (IBM created in 1971 is called "disket" (disk + biscuit).And a more compact and large -capacity hard disk and silicon memory (PCMCIA memory card and SD card) have appeared.

As the center of the information equipment evolves from the main frame (large computer) → desktop PC → mobile PC → mobile phone → smartphone, physical recording media is also required to change and innovate from the market, and it has responded from the past to the present.rice field.

The story was somewhat stuck on the side road, but the first USB memory has appeared as an alternative storage for floppy disks, which have become the limitations of operability and physical expansion.3 of IBM, which had already reached the world's largest capacity at the time.5 inch desket 1.44MB and 2.Two types of 88MB.It was inexpensive 1 that was used more.It was 44MB capacity.

This 1 is 1 to install OS (Operating System) such as Windows and OS/2 during the founding period or on a large package software..I needed about 5 to 30 floppy disks with 44MB capacity.The CD-ROM and USB Memory appeared to improve their inefficient operability.In addition, there was a place for USB memory in a mobile computing environment, which has become popular at the time.

The capacity of the first IBM USB memory key is only 8MB.But at that time.The large capacity of six 44MB diskocks was a valuable existence.On the other hand, "HIDISC Toshiba 3D TLC equipped USB3.1 Flash Memory (HDUF129C1TG3; then high -speed USB flash memory) is a very large capacity of 1TB.Roughly calculating, the capacity is 125,000 times the 8MB of the first IBM USB memory key.

The "IBM USB Memory Key" (8MB), which was announced in 2001 and released, did not require dedicated driver software, and was the world's first USB memory that would automatically recognize a PC equipped with a Windows OS at the time.

IBM USB Memory Key (above) and high -speed USB flash memory (bottom) purchased this time.Even after nearly 20 years, the appearance size is almost the same ... but the capacity has increased 125,000 times.

With the 80 column punch card of the paper mentioned above, the amount of data that can be used at most is 80 bytes per piece.Even the 8MB IBM USB Memory Key, which appeared in 2001, has 100,000 times the capacity of one punch card.The 1TB high -speed USB flash memory is 125,000 times.If you try to calculate with a normal calculator, 1TB is full of digit.

The recording medium has changed dramatically in decades, from punch cards, which had only 80 -byte data capacity, floppy disk, hard disk, and silicon memory cards.
