According to IDC, in 2014 the number of data will increase by 2.16 zettabytes worldwide (1 zettabyte is more than 1 billion TB). By 2016, the figure was 3.77 zettabytes and even more in 2018. Storage devices and semiconductor technologies are two of the fastest growing areas. Calculated from 12 to 18 months, the HDD, SSD … will have double capacity.
MicroSD memory cards from 128 MB up to 128 GB
In 1956, IBM introduced the first hard drive called RAMAC 350 (Random Access Method of Accounting and Control). The RAMAC 350 has “appearance” and “pit” dimensions, weighing about a ton. It has a capacity of 5 megabytes, just “stored” an MP3 song, costing about $ 1000 per megabyte.
Today, 3.5-inch HDDs, 4TB (5TB at the end of the year), store up to 760,000 songs. In addition, WD’s data center drive, filled with up to 6 TB of helium. Do you think this is great? By 2020, Seagate expects a technology called HAMR that will allow up to 10 times the hard drive space. That means the future HDD will have 60 TB, enough for 15 million songs or 6750 hours of HD video.
Digital data storage technology over years
Storage solution for businesses
EMC Symmetrix acts as the first virtual server in a data center solution for a corporate organization. On the left is EMC Symmetrix 1 with 2 GB, right EMC Symmetrix VMAX (10th generation) has 2 petabytes, 1 million times more than the first generation.
The speed is getting faster
Dysan Disk Pack was born in the 70s with a capacity of 200 MB, this disc is 14 “in size and weighs about 0.5 kg. The disk pack can be mounted to IBM 1311 hard disk drive, each disk has 20 sectors (physical area), each sector is 100 characters long and transfers data at 50 Kbps. Now we have a 512 GB NAND flash PCIe flash drive that you can find in a mobile device that can achieve 2 Gbps bandwidth with 4x PCIe 2.0.
The size is getting smaller
The RA80 was introduced in the 1980s as one of the first storage devices to use a 14-inch, 124-MB platter disk, which included 30 sectors, each capable of storing 412 bytes data. Today there is a 5-inch Microdrive drive from Seagate. In fact, the Microdrive was launched in 1999 by IBM’s 1.8-inch, 1-inch, and 0.85-inch models, which are used in MP3 players. such as iPods. Microdrive is the best example of a hard drive technology that allows you to “cram” large volumes into a small size. Today, you can easily see 2 TB hard drives with 2.5 “size.
Magnetic tape storage will be “dead”?
Tape storage, which began in the early 1950s, has been predicted to disappear several times, but so far they have survived, although the popularity is not as good as if it were not too small to compare to disk storage.
Digital data storage technology is developing faster and stronger than ever since the beginning. Nowadays, scientists have found a new storage technology in AND of humans. There’s no doubt that it will grow even more dramatically in the future.
