Micro Sd Class 4 6 10

SD and microSD cards of various speed classes

The SD Association came up with a way to standardise the speed ratings for retention cards. They are known equally Speed Classes and refer to the absolute minimum sustained write speed for both SD and microSD cards. In that location are 3 types of speed class:

Speed Class
UHS Speed Form
Video Speed Course

Numbers with a round "C" symbol, "U" symbol or a "V" symbol next to or around them indicate the speed classes of the memory carte. Manufacturers employ these speed class symbols to indicate the type of speed grade and rating on the retentiveness carte du jour. They are intended to help consumers choose the right memory bill of fare for their hardware devices in terms of speed.

Speed class

The very first speed course is simply known as the original Speed Class and is denoted with a "C" symbol. There are 4 ratings within the Speed Grade:

C2 (Class 2): minimum write speed of 2MB/s
C4 (Course 4): minimum write speed of 4MB/s
C6 (Class half dozen): minimum write speed of 6MB/s
C10 (Class ten): minimum write speed of 10MB/s

C2 is the slowest speed form while C10 is the industry standard. Since newer hardware devices crave newer speed classes with higher speeds and capabilities, hardly anyone uses Grade ii–six nowadays. C10 is unremarkably the minimum speed class requirement for most hardware devices fabricated today and is the most shipped retentivity card on the market place.

UHS Speed Class

The adjacent speed class up is the UHS (Ultra-High Speed) Speed Course and it'southward denoted with the "U" symbol. There are two ratings within the UHS Speed Class:

U1 (UHS Speed Class 1): minimum write speed of 10MB/south
U3 (UHS Speed Form iii): minimum write speed of 30MB/s

The UHS Speed Form is more normally used nowadays than the Speed Class and many high-end cameras require at least a U3-rated memory card for many of its functions, such as recording high-resolution videos. The UHS Speed Class mainly refers to the minimum sustained write performance for recording videos and came about due to 4K-capable video recording devices needing faster write speeds. As a rule of thumb, 4K-capable recording cameras will commonly require at least a U3-rated SD carte du jour.

What makes the U1 and U3 retentiveness cards more advanced than those in the Speed Form are that they utilize one of two UHS bus interfaces:

UHS-I: theoretical maximum transfer speeds upwards to 104MB/southward
UHS-2: theoretical maximum transfer speeds up to 312MB/s

Both U1 and U3 retentiveness cards tin can use the UHS-I bus interface, simply are not compatible with the UHS-Ii bus interface.

These UHS jitney interfaces indicate the theoretical maximum read and write speeds, unlike the sustained write speeds of speed classes. The UHS double-decker interfaces are denoted by a Roman numeral "I" or "II" symbol on the forepart of the card. The bus speeds refer to the theoretical data transfer rate of the interface itself while a U3-rated SD card has its own sustained write speed of 30MB/s. For example, a UHS-I U3-rated carte guarantees a write speed of 30MB/s simply has the potential for a read and write speed of up to 104MB/s if used with a device that supports a UHS-I bus interface.

A UHS-Two compatible card has a potential read and write speed of upwards to 312MB/s. The UHS bus interfaces are backwards compatible so you can use a UHS-II card in a device that supports UHS-I, but you won't see the speed benefits of UHS-2 as the card volition default back to the lower specs of UHS-I. Both the menu and bus interface must be fully compatible to feel the speed benefits.

Video Speed Class

The latest Video Speed Class was created to enable higher video resolution and recording features, such as multiple video streams, 360-degree capture, VR content, and 4K- or 8K-resolution videos. They're usually denoted with the "V" symbol. At that place are five ratings for the Video Speed Form:

V6 (Video Speed Class 6): minimum write speed of 6MB/southward
V10 (Video Speed Class ten): minimum write speed of 10MB/s
V30 (Video Speed Class xxx): minimum write speed of 30MB/southward
V60 (Video Speed Class threescore): minimum write speed of 60MB/s
V90 (Video Speed Class 90): minimum write speed of 90MB/s

The Video Speed Grade is unique because it's capable of utilising both the UHS-I and UHS-II bus interfaces. V6 to V90 speed class retentiveness cards tin use the UHS-II motorbus interface, simply the UHS-I passenger vehicle interface can only support V6 to V30 speed course memory cards.

The Video Speed Class offers the fastest speeds available and is ideal for ultra-high-resolution videos, high-quality videos and multi-file recording in drones and 360-degree cameras. It supports Hard disk formats up to 8K video in drones, 360-degree cameras, action cams and VR cameras.

Yous can find the best card for your hardware device past choosing the same speed grade or higher than the one required for your device. For example, if your device requires a Course four memory card, yous can use Speed Course 4, half dozen or 10. If your device requires a UHS Speed Class ane card, yous can use UHS Speed Form 1 or 3. The same functionality applies to the Video Speed Form also. Note, using a higher-rated carte du jour that goes beyond the speed grade requirement for a device will still work, but you won't exist experiencing the total benefits of the college speed class since the device only supports the lower speed class.
