How to choose a flash drive: memory size, interface, case and design
There is no such person who does not know what a flash drive is. It is difficult to imagine how they managed without it before. Drives are forgotten, most will not even remember floppies. With a flash drive more convenient and easier.
The first flash drives appeared in 2000 and had a memory of 8 MB. Today, models of 8, 16, 32, 64 and more GB are popular. The full and correct name of the drive is USB Flash Drive, or USB drive.
Often the question arises, how to choose the right USB flash drive for the computer? Only at first glance it seems that choosing is easy and simple, but in addition to appearance, there are decisive factors in the purchase. Before we consider them, look into the past.
Appliances and the Internet in place are not worth it. In 1984, there was an exhibition of electronic devices, where they presented a storage device - a prototype of a flash drive. It took several years to refine and improve the device, which was later used in military technology.Flash drive was expensive and inaccessible to the public. In the mid-90s. last century, developed the first USB interface, and in 2000 appeared flash drives, developed by Israeli scientists, they were called DiskOnKey. Gradually the volume became larger, the design also changed.
Memory size and interface
The first thing you notice is volume. Popular are flash drives with a capacity of 8, 16 and 32 GB.
4 GB is enough to transfer files, you can even listen to music in the car. If you upload movies, it is worth taking 16 GB or 32 GB. Drives of 64 GB or 128 GB are purchased by avid movie fans. They store text documents, photos, music and some of the best New Year films at the same time. A flash drive can be purchased as a gift.
When buying, pay attention to the interface. If the computer motherboard supports USB 3.0 interface, buy a USB flash drive with the same interface. USB 2.0 will also fit USB 2.0, even USB 1.0, only the speed is lower. Read the characteristics of the models, consult the seller.
If on the package are abbreviations Hi-Speed or Ultra Speed - high-speed flash drive. Models with a write speed below 10 MB / s do not buy, it is a waste of time.10 Mbps and higher is a reasonable solution for writing and reading.
If we consider in detail the issue of reading and writing, I will note interesting facts: the difference in price, as in the case of the player, is imperceptible, but the difference in file transfer time is significant.
For example, flash drives are purchased at the same price, but with different read and write speeds. 5 minutes are uploaded to one film, 10 minutes to another. If you pay more and take a proven brand, the file transfer time will be reduced, and the film will download in 3 minutes. Do not pursue cheapness, remember the expression: "A miser pays twice!"
Pay attention to the rewriting cycles - the defining indicator of shelf life. Usually varies in the range of 10,000 - 100,000 times. Each addition or deletion of information is considered for 1 time rewriting. It turns out that 10,000 times is not much, considering that actions from a flash drive are carried out several times a day. Not all carriers work out the stated amount of rewriting, there are fakes or manufacturing defects.

Body and design
Cases of flash drives are various:
A flash drive with a plastic case is cheaper than a metal one. It is difficult to damage and information is stored longer. It is worth paying attention to the rubber case: such models are shockproof and waterproof, suitable for active users.
If the person is neat, the plastic case will do. Such a product is an ideal contender for the title of the best corporate gift for the New Year.
Caps are simple (usually removed and dressed), retractable or on a chain. There are small flash drives without a cap. Choosing a cap is an unimportant parameter, choose any one you like.
A beacon is built into the case that glows or flashes during data transfer. This is good when working with a computer, you can see whether the file is being copied or not. If you intend to watch movies or listen to music, choose a device without a beacon. It distracts from viewing or from the road if you are in a car.
Also pay attention to the size of the case. If it is voluminous, another flash card in the USB connector will not fit next. It turns out, the simpler the design, the better! Design choose what you like, as long as it does not interfere with the work with the media.
Data protection form
Manufacturers on flash drives establish a serious degree of information protection:
- cryptography system
- fingerprint reader.
Protected models are sold in specialized stores and are expensive. Ordinary people such devices are not required. Bearers with a high degree of protection are people with access to top-secret information. Do not chase after newfangled things, choose an ordinary USB flash drive, you can protect information in other ways.
There are flash drives in which are built:
Buy these devices separately. The function of the flash drive is the storage and transfer of information, everything else is useless. Why do you need a flashlight in it? He will not light the way in the dark. Such gadgets if you buy, then only as a gift.
Choosing a flash drive as a gift
In addition to the determining factors, appearance matters. You can order an individual gift model or choose a ready-made version of a popular brand. Gift drives are made in gold or silver case, in precious stones or with rhinestones. The forms are also diverse: in the form of a bracelet, car keychain, figures, steam-punk technologies. A gift for February 23 or March 8 is easy to get.
On the performance of gift options do not differ from the usual, except for the price. Treat them will have to carefully, otherwise the body will become unusable. Try to surprise friends, acquaintances or relatives with an unusual gift - a flash drive with a memorable inscription, the result will be stunning!
