We bring to your attention the top reliable, time-tested brands that create the highest quality, durable and advanced memory cards.

How to choose the right card

Form factor

SD-drives have three forms of execution, differing in size:

SD – the largest option (32 x 24 mm);

miniSD – 20 x 21.5 mm. Currently out of production;

microSD is the most popular form factor (11 x 15 mm). Such drives are used in all kinds of gadgets – smartphones, cameras, cameras, etc.

Map class

The key characteristic that determines the speed of writing / reading data. The corresponding marking (Speed ​​Class) is marked on the body of any memory card. Note:

  1. SC 2 – write speed just over 2 MB / s. Rarely used at present.
  2. SC 4 – write speed of 4 MB / s and higher. This is quite enough for shooting in HD format.
  3. SC 6 – more than 6 MB / s. The minimum class of cards that are suitable for filming Full HD video. Suitable for budget class gadgets.
  4. SC 10 is a common class with speeds above 10 MB/s. Used in DVRs, Android devices, DSLRs, etc.

UHS-enabled drives deserve special attention – the standard for ultra-high data processing speed. In this case, the memory card has a speed measured in tens of MB / s. All models with UHS support are classified as Speed ​​Class 10. There are several versions of the UHS standard:

  1. U1 (UHS SC 1) – identical in speed to Class 10 drives, but the demand is higher.
  2. U3 (UHS SC 3) – often used in devices capable of creating 4K video. Speed ​​- from 30 MB / s.
  3. UHS I – supported by most devices. Bus speed (max) – 104 MB / s and higher.
  4. UHS II – cards of this class are used on the top models of devices, since they have several additional contacts and require a non-standard connector. The bus speed in theory is 3 times higher than its predecessor – about 312 MB / s.
  5. UHS-III – cards with the latest bus interface, providing an incredible increase in speed – up to 624 MB / s. Suitable for 8K recording and 360-degree video shooting.

Card capacity

The standard response of managers at specialized points of sale will sound “the more the better”, but in reality this is not entirely true. For starters, many devices are limited in the amount of storage they support. In addition, why pay for gigabytes that will not be fully used. So, consider the most popular memory cards on the market:

  1. At 32 GB, it holds a little over 30 minutes of Full HD video. Relevant for portable gadgets, compact cameras, but on condition that the drive is not used for shooting above the specified resolution and RAW format.
  2. At 64 GB – holds about 90 minutes of Full HD video. Relevant for smartphones, any photo equipment and video recorders.
  3. At 128 GB – holds about 180 minutes of Full HD video. Relevant for laptops, as well as photo and video equipment. The best option for shooting in RAW.
  4. 256 GB and above – applicable in the professional field, as well as an intermediate drive.

Operating method

For smartphone

If we are talking about a budget model, then you may not feel the difference between a simple and advanced memory card. But for flagships that shoot video in 4K, a low speed indicator is contraindicated. For shooting Full HD movies, we recommend choosing a class 4 or higher model. For top-end smart phones capable of shooting 4K UHD video, you need a much more “nimble” drive – an U3 class product with a speed of 30 MB / s or more is optimal.

For Camera/Action Camera

For high-quality photography, Class 6 is optimal: files will be saved in 1-1.5 seconds in RAW format. But for continuous shooting, it is better to pay attention to a higher speed class – U3 or V30. You need to choose the storage capacity based on your own needs: for amateurs, 64 GB is enough, and for professionals it is better to take 128 GB and above.

High-quality video shooting requires a high speed class. Look for V30 class cards or higher. If you take a simpler option (for example, V10), such a card is capable of Full HD video – higher-quality video will slow down and be recorded in jerks.


DVRs often shoot video of rather average quality – with a resolution not higher than Full HD, which means that Class 10 is enough. It is also worth considering that the DVR writes data for hours, day after day, saving information cyclically, regularly replacing the old file with a new one. Such a load significantly accelerates the consumption of the drive resource. Therefore, it is better to abandon the low-capacity model.

Advice. On sale you can find special cards for CCTV cameras and DVRs. They have an increased resource. Our experts recommend paying attention to such models as Kingston MLPMR2 (very fast), SmartBuy Professional microSDHC Class 10 UHS-I U3 + SD adapter (optimal for DVRs supporting cards up to 32 GB), ADATA Premier microSDHC UHS-I U1 V10 A1 Class 10 + SD adapter (inexpensive option for regular DVRs).

For drone

There is no specific standard for this type of device, since different drone options have different parameters. And yet, a number of manufacturers set specific characteristics that are relevant for their drones. For example, a DJI drone requires a card with a capacity of up to 128GB and speed class 3. The Kingston brand has a product that meets these characteristics – Canvas React microSD cards.
