FREE GUIDE! Best SD memory- how to choose?

What memory card choose?

In last decade market of electronics has undergone a real revolution.
Not everyone following this progress is able to find appropriate storage media for modern devices such as cameras, smartphones or drones.

What are the differences between SD and CF cards?
What are the differences between the x600 (x633) and the 10?
In this guide I help you decipher all these signs and advise you how to choose the right card for your individual needs.

So let's start to explain the numbers and symbols.
The graphics represent the most common markings in different SD card manufacturers.

1. Card capacity - expressed in GB. This parameter tells you how many pictures or video material we can hold on the card.

2. Speed class - minimum write speed in megabytes per second. All modern cards are offered 10. The lower class models are outdated and too slow.

3. UHS speed - expansion of write speed classes. This is a minimal write speed in continuous mode where U1 is 10 MB/s and U3 - 30 MB/s.

4. Maximum reading speed - is the value of the audio CD and its multiplicity - x1 is the reading speed of 150 KB/s. To calculate the speed in MB/s, multiply the value by 0.15, for example: The x600 card will offer a read speed of 90 MB/sec (600x 0.15 = 90).

5. The maximum reading speed given in MB/s- is an alternative representation of item 4.

6. UHS class - another parameter specifies the reading speed. Initially SD cards were  reading at to 50 MB/s. In UHS-I technology, the reading speed is to 104 MB/s. UHS-II cards (cards have a long row of contacts). These cards have a maximum speed to 312 MB/s.

And ending there are a few more SD/SDHC/SDXC cards indications.

The original SD standard provided for the cards up to 2 GB capacity. For this reason, the SD Card Association has modified the tag twice: SDHC- the specification for cards up to 32 GB, and SDXC to 2TB.

So, which card for camera, photocamera, smartphone, drone?

First You should always check which cards are supported on your device.
Assuming that the hardware has been purchased and is as modern, it will probably support the SDXC format. For example, some SONY cameras require fast SDXC cards with a minimum of 64 GB card capacity.
All cards with speed class less than 10 You should not consider.
If You film in Full HD, it's enough for us with a 64 GB card, which with a maximum throughput of 100 MB/s will fit video about 85 minute. When shooting 4K You should have a 128 GB card (or maybe a few such cards). At very high data rates, the card should write at least 60 MB data per second.
If the camcorder shoots at 4K, then 128 GB will be the best option to avoid a cumbersome card replacement. Write speed minimum 60 MB/s.

4 Smartphone
It is best to have one memory card for your smartphone because continuous card replacement can make your card unusable. Some smartphones encrypt the card to use it as a phone memory (which is a good solution, since the laptops are never too much). This card will be unreadable to the computer. For music, movies, photos I would also recommend 128 GB.
4 Camera
Photographs require very fast SD cards. If money does not matter so much ;) it is best to choose a card in UHS-II technology.
4 Drone
In my oppinion You need a 64 GB card to you drone. Due to the flight time on battery, it will not be possible to fill out the card before battery it is exhausted (one battery usually up to 30 minutes flight in proffesional drones). If dron filming in 4K, card should write speed minimum 60 MB/s.
