Buy a flash drive 64 GB: specifications, recommendations
Buying a 64 GB flash drive is easy. Indeed, dozens of stores will gladly provide the “right” product to the future owner. Elegant appearance, low price and seller’s guarantee - it looks very convincing. But take your time. According to statistics, every second user is disappointed in the purchase. After all, it turns out that the drive does not meet other requirements, which sellers are silent about.
How to buy a 64 GB flash drive: specifications
For any information storage device, whether it is a hard disk, SSD or flash drive, there are two important criteria that are responsible for the overall performance of a portable device.
- Write speed. Measured in megabytes per second. The memory chip is responsible for the write speed. Similar microcircuits are produced by dozens of enterprises in China, Taiwan, Japan and the USA. And to say for sure who has a better chip is impossible. Since they all have in the lineup, both cheap and expensive memory chips. But in the context of the manufacturers of flash drives themselves, it is easy to find a high-speed drive. Following international requirements, the manufacturer indicates the maximum writing speed on the package. If the information is missing - a flash drive, with absolute certainty, low quality.
A decent write speed for flash drives starts with the following indicators: 17-30 Mb / s (USB 2.0) and more than 100 Mb / s (USB 3.0).
What does this write speed give to the user?
Saves time. The volume of 64 GB. Let the files be smaller, but anyway, they will take a long time to write to a slow chip. Regarding time: 64 GB is 65536 megabytes.
For USB 2.0:
- good speed (30 Mb / s) - recording time: 2184 seconds (this is 36 minutes);
- low speed (up to 17 Mb / s) - recording time: more than 3855 seconds (more than an hour).
For USB 3.0:
- good recording speed (more than 100 Mb / s) - recording time: no more than 655 seconds (10 minutes);
- poor write speed (let 50 Mb / s) - 20 or more minutes.
If time is not critical - buy any flash drive. But remember that all the miscalculations concern the maximum possible memory chip speeds for writing a single file. When it comes to a dozen to a hundred files, the speed drops by 20-50%.
Second criterion
- Read speed. Measured in megabytes per second. The drive controller is responsible for the read speed, which reads information from the memory chip. Here, the landmark is a playback device (recipient of information). To play music on a tape recorder, reading speed is not critical. When it comes to PCs or playing a movie in quality on a TV, the rate should be: at least 50 Megabytes per second (USB0) and at least 100 Mb / s (USB 3.0).
What read speed gives the user
When working on a PC or laptop - again, saving time on the transfer of information. When watching movies on a TV in high quality (FullHD or 4К), problems with video braking are eliminated. Especially for 4K, where the speed of reading from a flash drive should be higher than the bitrate of the movie itself. Otherwise, there will be braking of the picture and sound.
How to buy a 64 GB flash drive: brands
In terms of manufacturers of portable drives, the brands have proven themselves: Transcend, Adata, Kingston, Apacer, SanDisk, Patriot, Pretec, Corsair. The listed manufacturers give their products an official 5-year warranty. This already indicates the seriousness of the brand. We need reliability and durability, taking into account high-speed characteristics - it is better to buy a 64 GB flash drive from these manufacturers.
You need to purchase portable drives in specialized stores at the place of residence. Or trust the choice of time-tested online stores in your country. Flash drives are not the kind of product that, due to cheapness, can be bought on Chinese sites. Sellers, in the pursuit of profitability, send drives that do not meet the declared specifications. More often, a cheap chip is installed, in the firmware of which information about belonging to a worthy manufacturer is driven. In practice, such a miracle device is very slow and harms the user with braking.
