Data storage started with vinyl records storing songs in 1880. It could store 200 MB of data. Though, it could not rewrite the data & be for one-time use only. The first magnetic tape data storage originated in 1947. The tape could store 60 MB of data – data could be rewritten multiple times on the same magnetic tape.
The first hard disk drive came in 1957 named IBM 305 RAMAC. It could store 4 MB data and weighed 900 K.G. The hard drive could write & rewrite data in real-time. The first solid-state disk drive came in 1991 with a 20 MB data storage capacity. This drive had no moving parts & had only electronic circuits to write & rewrite data endless times.
Today biggest available hard disk drive capacity is 16,000 GB & the biggest solid-state disk drive available is 8,000 GB capacity. Their size is 3.5 inches * 2 inch & weight is only 500 grams (Half K.G).
The capacity of 20 MB in 1991 versus 16,000 GB in 2020 – is only 0.12 % of data storage capacity. The high-speed internet, YouTube videos, Industry 4.0, AI & machine learning technologies have become possible due to such huge data storage capacities available today.
Data storage capacity discusses how much data may be saved in a storage device. Different storage devices have changed capacities. Several have small data capacity while others have enormous data capacity.
The storage is a home where we put things for protection and for
future use. Data storage talks about a device where data is saved. It is associated with the computer through an input and output (I/O) process. It permits a computer to grip data, whichever for the time being or permanently. Data is protected either in electromagnetic or optical arrangements. The data kept can be saved By using a computer.
Types of Data Storage
There are two selections for data backup:
- Local Storage
- Remote Storage
The below are the types of storage under Local Storage.
External Hard Drive
This is like a hard drive installed on a computer. The only difference is that this hard drive may be persevered and removed from the computer.
Solid State Drive (SSD
It appears like a hard drive. Though inside it has no moving parts.
Network Attached Storage (NAS)
This is one or more fixed IDE or SATA hard drives linked to a network hub.
USB Thumb Drive or Flash Drive
Optical Drive (CD / DVD)
This type is ideal for storing media and software for distribution.
Cloud storage is the only type that comes under the Remote Storage Option. This storage space may be retrieved from any computer with an internet connection.
Units of measurement
- Data storage volumes are measured in bytes.
- Each byte is in fact a pattern of 8 bits.
- Bits are the elementary building blocks of data storage.
- 1 byte = 8 bits (for example 10011011)
- 1 nibble = 4 bits (for example 1001)
- Each bit is denoted by either a 1 or a 0.
- This is also recognized as binary code.
- 1 byte may grip 1 character of data, for example, p is 1 byte.
- All greater units are normally stated by their shortened names.
- Therefore, we could keep adding more prefixes to talk about increasing data.
We Need the Kind of Storage
Tools and technology have been progressed so quickly in the past few decades. The main hard drives thirty years ago would hardly be able to store more than a couple of modern MP3 files. Nowadays, customers purchasing a TB of external hard drive storage for their personal laptops may store 100,000 that amount.
Big floppy disks have been changed by tiny memory cards, USB drives, and a diversity of portable storage devices. However, the average user might not understand that the world is creating over 2.5 quintillion bytes of data every single day. By most of that data being shaped in the past few years.
A bit is the smallest likely data storage unit of measurement. We start talking about solutions with huge amounts of storage even though storage capacity for enterprises is slightly awaiting. Small businesses have more liberty. It may be sufficient to store files, images, or other important documents on CDs, USB drives, and low-capacity external hard drives for small businesses. Services similar to Google Drive and Dropbox let us store files online.
Digital storage needs;
- Physical servers
- Hard drives
- Cables, and other technology that requires to be stored.
We’re going to require much hardware when the business starts needing to store petabytes, exabytes, or even zettabytes of data. It’s significant to weigh the pros and cons of the different methods available to us. There are likewise options to depend on the resources of other companies and store the data in the cloud.
