A technology buff excited to share pendrive technology developments which have upgraded very quickly, replacing floppy discs and DVDs.
The Beginning of Pen Drives
The USB flash drive, which today is universally known as a pen drive, was invented by Fujio Masuoka in the 1980s. A pen drive was formerly known as flash memory, a kind of floating-gate semiconductor memory. To store data floating gate MOSFET transistors were utilized as retention cells, to hold data.
Since then, many folks have claimed to be an inventor of the USB storage drive:
- At the beginning of the 21st century, Amir Ban, Oron Ogden, and Dov Moran from an Israeli company named M systems
- Shimon Shmueli an engineer from IBM company
- Trek 2000 International, a Singaporean organization, claimed to have commercially sold the first USB storage drive
- Pua Khein Seng, an engineer from Malaysia are few patent filers and probable inventors of the revolutionary device. This finger size gizmo weighs less than 30 grams depending upon the designs and specifications.
The tiny gadget consists of an Electric Circuit board comprising of surface-mounted integrated circuits known as ICs, Write-Protect switch, Crystal oscillator, Test points, Controller device, information storage chip, LED light, and USB Connector.
As technology advanced the speed of data transfer increased exponentially which is governed by the speed of the controller device to read, write and transfer encrypted information and secondly by the speed of the hardware bus. Today USB 3.0 version drives are considered the fastest and high-performance device which could technically read at 92 MB/s and write at 70 MB/s which might differ radically when tested. The Latest high-capacity pendrives are equipped with temperature controllers, over current and short circuit protection chips, security keys, and biometric locks. Its been a long journey from version USB 2.0 to USB 3.0.
As of the year 2021, USB Pendrives can store upto 2 TB of data which can read and write highly rated 4K videos at lightning speed. It comes with various storage capacities starting from 1GB and maximum upto 2TB while the size of the device remains unaffected. Less than 1 GB of storage devices have become obsolete now. Most trusted stalwarts have developed 2TB USB 3.0 devices and are available in the market.
As Pendrive got evolved over the years, it replaced floppy discs and CD/ DVDs. Both have become almost obsolete considering the USB pendrives applicability. A Few of its ability is as follows:
- Backup – Storing of files and data’s in Pendrive as secondary storage or having a backup of all Infos under one device which can be plugged and accessed through any computer, laptop, or USB-readable device.
- Audio/ Video player – Music, audio, video, a podcast can be stored and played through an audio and video player
- Marketing -- Sharing products and services to B2B, B2C thereby marketing them endlessly through digital screens.
- Branding - Customizing Pendrive designs by imposing and printing company name and logo onto it enhances brand image.
- Authentication tokens – Allowing access to systems only when the device is inserted which consists of encrypted keys, security software.
Its applicability is huge and should not take long to replace heavy, bulky, and costly hard disk devices.
Encryption and Security
As a portable gizmo, the device can easily get stolen, misplaced, and lost but the content stored inside is completely protected from unauthorized access. Anyone can have their stored data protected with third-party encryption software in ZIP or Rar file format as a whole, which can be accessed through any computer, laptop, OTG supported devices. While some manufacturers have included hardware-based encryption in their design thereby eliminating the need for third-party encryption software. Likewise, the security it persists includes biometric scanning, password protected keys that only software drivers can authenticate. Manufacturers produce and design devices as per market needs.
- Mainly the size of Pendrive would be compact thereby integrating components and their functions in the single electronic chip which ultimately reduces the part count and whole package price.
- Memory cards and hard disk devices would be replaced by compact USB pendrives.
- Permitting controlled storage and usage of copyrighted material specially designed for students is labeled as FlashCP technology.
- Smart wearable Pendrive device cum wristwatches.
- Multi-storage chips which cumulatively stores all type of files but can be separated and used under various heads like only audios, only videos, only document, only photos, all encrypted under single device but separable at times needed.
- Enhanced security features along with biometric scanning, password-protected physical keys, cloud storage option, anti-theft feature, device tracking when stolen, self-protect, and self-delete data options when unauthorized access or security breach takes place.
- Increase storage capacity upto 100 TB
- Touch screen and display options which will indicate current operation or task performed, display read and write speed.
- Innovative Pendrive case designs shapes like keys, pen, coin, bullet, burgers, and many more customizable Pendrive case shapes.
- Transfer Speed enhanced to double rapidity upto USB 6.0 compared to the current USB 3.0 version thereby growing the read and write speed upto 500 MB/s to 1TB/s.

These days laptop don’t come with optical drive for inserting CDs. Next 5-10 years would reduce CD usage completely.
Mick on May 21, 2021:
CDs are still used for drivers, manuals, tutorials.
Pendrive itself includes drives which automatically gets installed once plugged into new laptop or computer
