Memory Cards

Type of

There are many types of devices on the market. Characteristics suitable are indicated in the description of the device for which it is intended. A larger number of cameras use type - SD. In turn, this type is subdivided into two subtypes - cards of greater and extra large capacity.Digital cameras manufactured in 2005 and earlier may not be compatible with high-capacity cards. And models released a few years earlier may not support a card with extra large capacity. Professional cameras are mainly equipped with a flash card type CF (CompactFlash). They differ slightly from other types in some characteristics, in particular, in their larger volume and fast write speed. But before buying this you should make sure that the camera can provide a high transmission rate. Also, the device must be equipped with the function of direct memory access. Tablets and smartphones, which are characterized by compactness, support a smaller version of microSD, like DVRs. These can support some models of handheld cameras.

Miniature cards are not inferior to other types neither by properties nor by functionality!

The speed and amount of memory microSD is the same as that of the SD. Many camera manufacturers are developing their own types of flash drives. In this case, the camera should have two separate slots or a combined one.

How much memory card is needed?

The volume of the memory card will help determine the number of pictures or videos that fit on it. Of course, more capacitive devices are much more expensive.Modern SLR cameras, even mobile devices have an image resolution of up to 40 million pixels, and I advise you to install a memory of at least 16 GB in the video recorder. On average, the number of pixels ranges from 12 to 20 million. Therefore, the greater the resolution of the photo, the more space it takes.

Therefore, for home use, I chose 16 GB, if you are no longer a fan, then 32 GB, and 64 and 128 only for professionals!

The volume that the image occupies on the map depends on the quality of the image, that is, the number of small parts. The same applies to video files. More space is occupied by those video clips that have greater quality and resolution. Thus, RAW video weighs up to 30 megabytes per frame. Few people like the situation when the memory stick ends at the most inopportune moment. To avoid trouble, you need to buy a memory card, which reaches 32 gigabytes. Below is a very useful table that clearly describes the number of JPG images weighing 3.5 megabytes and Full HD video clips can be recorded on memory cards of various sizes.

Which class of memory card is better?

Surely you do not pay attention to such a parameter as speed. But it is no less important than the volume, because it is responsible for the scope of application. A slow memory card will not be able to provide a decent recording of Full HD video, because shooting will stop. Shooting a series of frames on a USB flash drive at low speed will cause the camera to freeze. This is a rather inconvenient circumstance that can be avoided if one learns to correctly distinguish a slow card from a fast card. On SD cards, which are the most common, the speed class is indicated, it happens:class

This number indicates the write speed. That is, the second class indicates a speed of 2 megabytes per second, the fourth is four megabytes, and so on. Only the last class indicates a speed that can reach above ten megabytes per second. The device always indicates the actual recording speed, be it 45 MB / s or 60 MB / s. Also with Compact Flash cards. For Full HD video, at least 6th speed class will suit, but it's better after all 10th. These flash cards are suitable for everyday shooting. Faster cards are suitable for shooting people and events when several shots are taken in a row. So you can shoot a short continuous series.A slower flash drive can skip interesting shots while the device records previous snapshots. If you need to shoot moving objects, the speed requirements are even more stringent. It is necessary to shoot a series almost continuously, so the best speed in this case is 45 MB / s. Acceptable for shooting motion speed zo MB / s, it will also minimize the interval between the series during recording on the memory card captured frames. For a professional photographer, you need a flash drive with a speed of 100 MB / s. So you can shoot a continuous series of shots until the memory runs out.

A less important parameter is the speed of reading. It is either higher or equal to the recording speed. Therefore, if you bought a memory card having a high write speed, then be sure that the read speed will be sufficient.

It is important to know

The memory card is fully protected while it is in the device. But it is exposed to great danger if removed from a camera or mobile device. Falls, scorching sun, severe frost - all of this has a negative effect on the flash drive. Worse, if water is spilled on it or the map is exposed to X-ray radiation at the airport.So it is better to buy a memory card that has protection from such a negative impact.

Based on the above characteristics, you can choose the right memory card for, tablet, camera, DVR, and for everything else. Each parameter of the device is important in its own way in different shooting conditions. Therefore, the choice must be made based on the type of camera or mobile device.
