I wanna buy a USB flash drive, but I have no idea about it. Are all flash drives the same? How many types of flash drives are there? What is the difference between 2.0 and 3.0 USB? There is too much information and I am so confused. Can anyone help me figure out the difference? Many thanks!
Are all flash drives the same? The answer is certainly not. Not all USB flash drives are produced equally. They are different in many aspects, such as the appearance, the usage, the storage capacity, the speed and ports, and many more.
In this article, we will introduce different types of flash drives based on their usage, looking, and storage capacity. But before that, let's have a snapshot of the flash drive.
USB flash drive also called a thumb drive, jump drive, pen drive and USB memory stick is a device that can be used to save information on a tiny flash memory chip. Users can read and save data on it. These storage devices have been designed to be smaller than a typical storage disk, with some being the size of a thumb. That is why some people know them as pen drives, while others prefer to call them "thumb drives". Whatever the name, they all share one important characteristic, they can be hooked up to any computer. Thanks to their universal serial bus (USB) port compatibility.
There are 2 types of memory being designed to save and store data on different devices, respectively volatile and non-volatile.
Volatile memory is temporary data storage. For example, the computer hard disk drive takes advantage of volatile memory. It writes and reads data using the moving parts only when the computer is on. And often, you can hear a clicking sound when the computer is working. It means that the moving parts of the hard disk are reading your data. Without a power source, it would be not possible for you to have access to the stored data.
By contrast, the USB flash drive is a non-volatile device. It has to resort to power to save, transfer, and put data onto it. However, it can keep data stored inside it without a power supply. It will transmit a memory command in the form of an electronic signal to the internal circuity. Even if there is no power source for a long time from the connected and powered-off computer, it can retain all the information without any harm and quality loss.
So, how does a USB memory stick work on a computer?
The Flash memory stick has no moving parts. A flash drive can be compatible across devices through the USB ports. By plugging the pen drive into the computer USB port, the device can start writing, reading, transferring, saving, and storing data. The data inside it will not disappear unless you remove them manually or something goes wrong with the memory stick.
The USB port is used to create the interaction between a flash drive with your computer. To meet different needs, there are different types of USB flash drives based on the ports, respectively USB 2.0 flash drive, USB 3.0 flash drive, USB 3.1 flash drive, and 3.2 drive. The biggest difference between them is the price and speed. But the price varies due to the storage capacity, brands, and many other factors. We will mainly talk about the difference in speed here.
Can a USB 2.0 be used in a 3.0 port? Yes, 100%. You can insert your 3.0 flash drive on a USB 2.0 port. But as we mentioned, a USB 3.0 thumb drive in a 2.0 port can't perform at the maximum speed.
Flash drives and pen drives are two terms that we use interchangeably today. However, that was not the case 15 years ago.
Flash drives were devices that ran on flash memory. Their sole purpose was to store information and transfer it between the connected computers. The connection takes place through the USB port that is on the hardware.
Pen drives, on the other hand, were bulkier than flash drives and had more length to it. Due to their elongated size, they were given the name Pen Drives. They also ran on flash memory and had a USB interface to communicate with the computer.
Nowadays, the difference in size is no more. All the flash drives and pen drives of today have the same function, the same internals, and the compact form factor. So there is no real distinction you can draw from them. Hence, the pen drives and flash drives of today are essentially the same.
Next, we will go over the different types of USB flash drives. Please note that they can be categorized according to their uses, or physical characteristics. We attempt to find a balance between the two.
Looking back to history, USB flash drive has developed varied application scenarios result from different needs. In this section, we will learn some types of USB flash drives that you may not hear of.
This is a normal USB storage device with a major twist in terms of the steps taken to protect your data. It is fortified with physical or logical security ways to ensure that the data is not compromised.
An example is the flash drive from Cryptex, which has a combination lock before you can access the USB disk embedded within. Others, like those from IronKey, come with an internal mechanism like password protection and encryption for added security.
All in all, these devices provide added security for the protection of all data. However, you will have permission to add or remove write protection to keep the flash drive more secure.
This is a flash drive that can be used to save or transfer music from one device to another. They may vary by fancy designs and different flash drive types, such as this one from SONY.
However, most of them are designed to be miniature and to enhance portability. The reason for this is because most people who want to carry their music files around in a flash drive want them to be easy to reach, while also to be out of the way.
A boot flash drive is a normal USB memory stick that has been enabled to install an operating system. The process of dedicating an external storage device to serve this purpose is called "making bootable”.
Whenever you have a computer that won't start because of a missing operating system, simply use a boot flash drive to fire up the computer. If you don't have one currently, get one for standby reasons.
