USB sticks or flash drives as they are sometimes called, even memory sticks and probably a whole lot more different terminologies for this product, but I believe we both know what I am referring to.
Businesses are competing for the sale of their brand of USB sticks, but there are a few things you need to be aware of when buying these sticks, whether they be online or from a corner store.
In essence a USB stick is just a device that plugs into a port with a tail that (in essence) houses a cache <available space for storage> USB Ports however are becoming so much more.
These USB sticks are built with different transfer speeds governed by the software onboard.
Transfer speeds and what they mean to the user.
Universal Serial Bus 1.0 was introduced in January 1996 It is the original design, (mark I) if you like. which was frequently referred to as simply “USB”. The USB 1.0 technology was developed by the following: IBM, Nortel, Compaq, Intel, DEC, Microsoft, and NEC. They were devised as a way to standardize a protocol for connecting multiple devices, eliminating the need for multiple types of connectors and also allowing more bandwidth for devices. At this time, connecting devices were getting messy and a new way was sought to standardise this. USB cables were able to transfer up to 12 Mbps, which was much faster than any previous protocols. This made it feasible to connect hard disk drives and other devices that required high data transfer speeds to operate correctly. These connections also allowed for data transfer to/from another device. The wiring of this connection consisted of a ground and a positive (5 volt) feed to power another device, coupled with data transfer bar to the device and data transfer from the device, Excellence in its simplicity eh?
USB 2.0 was released in 2000 as an improvement to the USB specification.
It boasted speeds of up to 480 Mbps, which was by far, an improvement over the original speeds of USB 1.0. At this time USB 2.0 became very popular and is still the most popular connection type for peripherals in use today. Most computers and laptops include at least two USB 2.0 ports, and some include even more, owing to the increasing need for more ports to connect users’ devices, because of the popularity and wide use of this style of connection.
USB 3.0 was released in November of 2008, and is yet another improvement on the original protocol. USB 3.0 products looks to be a big improvement in speed, as it can theoretically reach speeds up to 4 Gbps, which is faster than the limitation of most hard drives.
While USB has been around for a few years now, its continued improvement and refinement means it will likely be around for years to come. The promise of very fast transfer rates for USB 3.0+ means that it could replace virtually every connection on a computer or laptop.
Don’t let us forget that the port needs to accommodate the speed asked of the device. (The host controller directs traffic flow to devices) So in other words, the USB devices that are (for example) USB 3.0 it will be backwards compatible to USB 2.0, which could be the host controller speed) however if the speed of the port is only USB 2.0 speed, then the USB device will still work but at the speed of the port (USB 2.0).
