Overview of memory cards microSD and USB OTG Leef flash drives
In the life of every man comes the moment when he needs to go on a business trip. It would seem okay, but bad luck, having become accustomed to move around the hometown by car, you realize that the smartphone is not pumped at all for traveling in other types of transport. I didn’t even install a banal memory card ... I had to arm myself with two devices: a microSD Leef with 16 gigabytes and a Leef Bridge flash drive. Samsung Galaxy S4 LTE sighed more freely .... Under the cut a few details about my acquisitions.
It is logical to assume that the choice of the manufacturer is not accidental. I will not deny the obvious. In addition to Leef, there were no other OTG flash drives in the assortment, and there I bought a memory card according to the principle “let it be the same”.

The main objective of OTG flash drives - fast data transfer between a smartphone and a computer without the use of cable and software. It is worth noting that there are no obstacles to using Mac OS X. The opportunity to take films with me, not bothering that there is not enough space in the phone and to watch them directly from the flash drive, I was just captivated. The memories of last summer are still fresh, when it turned out to be impossible to take a bunch of cartoons for two children on a two-week vacation, having a 16-gig iPad in their hands.
The memory card in the phone for me personally is a repository of books and photos, I rarely use voluminous applications, there is no music in the phone, I don’t watch movies. The built-in memory of the device was quickly filled with maps from the CityGuide navigator, I take a lot of pictures - you need to increase the storage capacity.
Another nice thing is the waterproof card. If the data on it is more important than the smartphone itself, then when moisture gets into the phone, you can not worry about the safety of information.
Just to tell about the device is not interesting at all, so I’ll give you USB and microSD speed characteristics.
SanDisk Extreme, which is more expensive than the experimental and “one-class” at the price of Silicon Power
The results are as follows:
For USB OTG, the rivals will be the same brands: Silicon Power Mobile X10 and SanDisk Ultra Dual
Results: SanDisk reads much faster, but slower to write; with Silicon Power, we can say parity; when reading movies, the difference is almost not noticeable
What can I say on the end: in addition to moral satisfaction and the ability to carry a movie with me, I received high-quality devices for reasonable money. A special feature is the nice design and water resistance of the microSD card. For USB OTG - a cool case is made that does not require caps.
