The flash drivesalso known as flash drives, they are a very useful storage medium for making backup copies or transporting data between devices, among many other uses. They are a more "standard" alternative to memory cards to make backups or simply play multimedia content on your Smart TV or other players. But if you are wondering, which USB should I buy? My answer is: it depends what you need it for.
In this article we will give you a brief review of the types of flash drives or available flash drives and what you should keep in mind before buying a USB flash drive.
history of pen drives
Before getting down to business, let's look at a brief overview of the history of pen drives, and that is that these small flash memory units have been with us for almost 20 years. In it year 2000the companies IBM Y Trek Technology They were the first to launch the first USB flash drives on the market. On the one hand, Trek Technogy presented a USB memory called thumb driveand IBM put out for sale a pendrive model that received the name of DiskOnKey.
The company that designed the first memories was an Israeli company called M-Systems. The first USB model they created had a capacity of 8, 16 Y 32MB. Nowadays talking about megabytes sounds ridiculous, but back then USB drives were a revolution and put an end to the use of 3.5″ floppy disks and their 1.44 MB capacity.
As a curiosity, these first USB storage units had a small battery inside, since they still did not use the electrical current of the USB port to be powered.
USB memory capacity
There is no correct or recommended size for a flash drive, you simply have to find one whose capacity meets your needs based on the amount of data you want to store. The capacity of the first USB flash drives ranged from a few hundred megs, to more than 1 TB today.
On the other hand, if you want to store larger or heavier content, such as photos and videos or movies, you may need several tens or hundreds of GB.
Another factor that you should take into account when buying a flash drive is the Transfer speed. There are currently two types of USB flash drives:
- USB2.0: is the older standard of the two. The maximum transfer speed for a USB 2.0 is 480Mbps.
- USB3.0: the most modern standard. The maximum transfer speed for a USB 3.0 is 4,800Mbps either 4.5Gbps. This means that the USB 3.0 is approximately 10 times faster than the USB 2.0 standard..
The type of USB you choose depends to some extent on the device you are going to use it on. If your PC only has USB 2.0 ports, even if you connect a USB 3.0 pen drive, the maximum transfer speed of the pen drive will be that of the USB 2.0 standard.
Without a doubt, flash drives or pen drives are a storage solution economical, fast, comfortable and reliable comfortable. But this comfort presents some risks that you should be aware of:
- Pen drives are usually small in size. This makes them very convenient to carry, but it also makes them easy to lose or misplace.
- An infected flash drive can spread viruses or malware from one computer to another.
When the data you need to transport is especially sensitive, you can opt for a professional-grade pen drive, with the possibility of being encrypted at the hardware level with 256-bit AES encryption.
Common problems with flash drives
To minimize the risk of data loss when a USB stick is lost, you can use software and hardware encryption. When you encrypt a flash drive you help prevent the transfer of malware and unauthorized access to your data.
USB device is not recognized
On certain occasions, the operating system does not detect or recognize the USB stick that you just connected, and the truth is that it is a more common error than it seems.
The most common faults are problems in the data table, format problems or in a driver failure that handle the USB device.
If when connecting your pendrive, Windows shows the dreaded message that the USB device is not recognized, try to carry out some of the solutions proposed by the guys at tutecnopro.

The price of pen drives
The price of flash memory is directly related to its size. Generally, the more memory, the more expensive a flash drive is. It will also cause the price to vary the type of standard. USB 3.0 is faster and also more expensive. Depending on the use you are going to give it, a USB 2.0 may be enough.

The smallest and lightest flash drive

The biggest drawback of this type of memory is that it is very easy to lose it.
