The new millennium ushered in with a bunch of amazing possibilities and developments and when it comes to some of the most phenomenal century-defining development- USB Flash drive surely commands massive kudos and appreciation. Popularly known as pen drive or thumb drive, these little flash drives have revolutionized data storage and portability, showing us a more powerful and way better alternative to traditional CDs and floppy drives. They speak of a handy data storing device (around just 1.1 oz), equipped with flash memory & integrated convenient USB interface. These devices are usually removable & rewritable several times. All major operating systems like Linux, Windows, OS X & Unix-like systems are compatible with USB Flash drives. All PCs and laptops today are manufactured with in-built USB ports where you can plug-in the USB Flash drive to gather and transfer data. As the old adage goes-"All great things come in small packages" – and so are the USB Flash Drives.
The article below discusses everything you would wish to know about USB Flash Drives
History of the USB Flash Drives
Though there have been steaming debates about the creator of USB Flash Drives, yet many claim that Pua Khein-Seng, a veteran electrical control engineer from Malaysia, was the actual man behind the thumb drives. Revered as the "Father of Pen Drive", Khein-Seng was the one who incorporated world's 1st USB single chip flash controller. He founded the Taiwan-based Phison Electronics and had supposedly produced 1st USB Flash Drive of the world with the system-on-chip technology. However, Singapore's Trek Technology & China's Netac Technology have made competing claims.
1st generation USB Flash Drive
The 1st commercial USB Flash Drive forayed into the market in the year 2000 through IBM and Trek Technology. Under UBM it was sold under the name of "DiskoNKey" across North America while Trek started selling the device as "ThumbDrive". IBM's model was manufactured and developed by Israel's M-Systems. The first commercial model was released with 8 MB storage capacity that was 5x more capable of the conventional floppy disks (1440 KB). It featured USB 1.1 connectivity.
2nd generation USB Flash Drive
The 2nd generation USB Flash Drive hit the floors in 2003 with a more powerful USB 2.0 connectivity, carrying 480 Mbit/s transfer rate. Reports on history of pen drive show 64 MB storage capacity & later 128 GB with the second generation USB flash drives.
3rd generation USB Flash Drive
The 3rd generation model came with a better USB 3.0 which phenomenally heightened data transfer to up till 5 Gbits. It came to the commercial market in 2010. By 2014, 32- 64 GB pen drives started coming up. The more advanced models were equipped with 1 TB capacity.
4th generation USB Flash Drive
The 4th generation USB Flash Drive speaks of type-C USB 3.1connectivity with 530 MB/s read/write speed. It was announced something around 2015 March.
Make and Technology of USB Flash Drive
Pen drives come with a little printed circuit housing circuit elements inside a plastic casing, fitted with standard-A USB plug at the end- it's the USB connector that establishes the connection between the drive and the PC/laptop. A handy removable cap protects that USB connector. The standard USB Flash Drives generally bank on a USB type-A connection which enables the connection with the port on PC.
The 5 main components of USB Flash Drive:
- USB Standard-A Plug- it extends physical interface to host computer.
- NAND flash memory chip- it plays the main role in storing data.
- USB mass storage controller- you have a tiny microcontroller with small volume of on-chip RAM & ROM.
- Crystal oscillator- it produces the drive's vital 12 Mega Hertz clock signal & controls its data output via phase-locked loop.
- Cover- usually made of metal or plastic, it is meant to safeguard the electronics making up the device from mechanical stress & short circuits.
- Jumpers & test pins- these are useful for testing while manufacturing flash drive or while loading the code in its microcontroller.
- Write-protect switches- they help to disable or enable data write-up into memory.
- LEDs- they are to indicate data reads/ writes or data transfers.
- Free second space- provides room for 2nd memory chip.
- USB connector cap- for additional protection to the connector from dirt and damage.
- Transport aid- a convenient hole for lanyard or key chain.
- Memory card slot- Some of the USB Flash Drives come with memory card space for expandable storage.
One of the most frequently asked questions about USB Flash Drives is that how come these devices are so tiny. Well, these drives deploy solid-state advanced flash technology that can store your data sans using the elaborate moving parts- which are otherwise common with the larger PC hard-drives.
