Memory Card Need to Know Before You Buying
It would seem that the difficult thing about buying a memory card. Determined with the right volume, found a good offer and bought. It is because of this approach of users that some manufacturers have stopped issuing flagship smartphones with the option of expanding memory. If you have a microSD card at hand, take a look – how much everything is written on it. This information will help to make the right choice.
Why deal with the memory card?
This is a question to start with. Imagine that you bought a new modern flagship smartphone with support for memory cards, for example, LG G4. Such a smartphone should easily cope with all the tasks, but suddenly you notice that the camera and other applications of your smartphone do not work as fast as you expected. This is possible if you use an insufficiently fast memory card, which stores photos and from which your applications take data. However, nothing prevents from paying a little attention to the issue and choosing the memory card with which the smartphone will be able to please you all the time.
What is the difference between SDHC and microSDXC?
When buying a memory card, you should pay attention to these four big letters, but the difference between these two standards is only in the supported amount of data. SDHC (Secure Digital High Capacity) allows you to store up to 32 gigabytes of data, while SDXC (Secure Digital Extended Capacity) can work with 64 gigabytes or more. The problem is that not all devices support SDXC cards and such a large amount of memory. Clarify information about the capabilities of your smartphone before buying a memory card at 64 or 128 gigabytes.
What does the memory card class say?
Memory cards microSD can be 2, 4, 6 and 10 class, and this is something that really needs to be paid attention. These numbers indicate the supported data rate, and if the microSD memory card can record data at a minimum speed of 2 MB / s, then the 10th class memory card operates at a minimum of 10 MB / s. Not so difficult. It is important to understand that this is the minimum recording speed, and with good memory cards, the data reading speed can reach 95 MB / s.
What does UHS mean?
Another information about the memory card that can get to your eyes is UHS-1 or UHS-3 compatibility. Such microSD memory cards began to appear in 2009. In theory, the UHS card can support a data transfer rate of up to 321 MB / s, but it is worthwhile to focus on the minimum speed: 10 MB / s for UHS-1 and 30 MB / s for UHS-3.
In fact, if you plan to use the card in your smartphone, do not focus on this, smartphones do not support UHS.
