SD standard works in any slot means compatible in all devices.

SD HC card will work only on those devices which are compatible with HC and XC.

But SD XC will work only on those devices which are XC compatible. unfortunately not compatible with other slots.

2. Speed (class)

As shown in the picture you might have seen number written inside C. Basically this C represents speed class , means class 4, class 6 class 10. And the number inside the C represents the minimum write speed, 4 means 4 MB/s , 6MB/s, 10MB/s.

Class 44 MB/sNormal speed
Class 22 MB/sLow speed

2.1 UHS standards

Modern Day Memory cards also have U written before its class which denotes Ultra High speed bus or simply only U.

  • U1 – write speed of 10 MB/s.
  • U2 – write speed of 20 MB/s.
  • U3 – write speed of 30 MB/s

3. Device compatibility

This is the most ignored thing before purchasing a card. for instance If you have a device which supports only upto 64GB then buying 128 GB one might results in device support problem.

Another thing that is to be kept in mind is its class type. If only C is mentioned on the card, means it support conventional type of devices only. And if only U is written means it will support only UHS 1 bus or UHS 2 bus compatible devices or in simple words high speed supported devices.

If both is U and C is mentioned , means it is supported by both type of devices.

4. Application Class Type

You might have also seen A1 , A2 written on the cards. This tell you if it is fast enough for apps on mobiles.

The SD Association introduced new application performance classes that will specify Micro-SD cards that are fast enough to be used for starting apps and programs. App performance Class is defined by the IOPS (input output speeds).

Application performance ClassMinimum Random ReadMinimum Random Write
A11500 IOPS500 IOPS
A24000 IOPS2000 IOPS

5. Video Speed Class.

You must have seen V90 , V60 , V30, V10 numbers written several times on the card, So these numbers tell you about the video class of that card and the minimum write speed for video recording. for example if you see V60 written on card the it signifies 60 MB/s for video recording.

This is mainly useful for camcorders, video recorders and other devices with video recording capabilities

6. 256x , 1500x , 2366x ,.. etc

You have also seen these type of number (not necessary these only) written on many cards .So basically this represents the comparison between the write speed with CD’s (compact disks). For example 1500x shows 1500 times faster than CD’s.
