SanDisk Extreme Pro vs Extreme – Features Face to Face

Write Speed

This number indicates the maximum transfer rate measured in MB/s or one megabyte per second. It is emphasized on the surface of the card. Keep in mind that the number usually represents the maximum read speed. That is the case in the picture below.

Of course, there are also models, where both read and write speeds, are pointed out. So, it is crucial to read the product specifications before purchasing a new memory card. 

For instance, this information is essential when taking high-resolution photos. In this case, a large amount of data should be written to the card as soon as possible. Simply put, the camera needs to be ready for the next photo.

The maximum write speed of the SanDisk Extreme is 70MB/s. But, if you want a device capable of recording videos or taking pictures fast, the Extreme Pro model might be the right choice. The Extreme Pro’s write speed is 90MB/s. 

Winner: Extreme Pro

Capacity and Storage

To better understand how much data can fit on a memory card, check out the table below. It provides general guidelines for storing music, videos, or pictures on a card. If you do not know which capacity you need, the table will help you determine it.

CapacityMusic (mp3)Photos (10 MP)Videos (HD)
2GB34 hours770 photos30 minutes
4GB68 hours1540 photos60 minutes
8GB136 hours3080 photos120 minutes
16GB273 hours6160 photos240 minutes
32GB546 hours12320 photos480 minutes

For instance, if you choose an mp3 audio format and a 16 GB-capacity card, you can store 273 hours of music.

The SanDisk Extreme capacities range from 16 GB to 256 GB. However, the SanDisk Extreme Pro comes with a wider choice of capacities. The lowest capacity is 32 GB, and it goes up to 1 TB. So, the Pro version wins in this segment. 

Winner: Extreme Pro

Burst Shooting

If you are a photography enthusiast, you probably want to take several burst shots. If you want to capture moving objects, you might need a card with a particular speed and class.

Both the SanDisk Extreme and Extreme Pro have V30 or Video Speed Class 30. Additionally, the U3 Speed Class 3 makes them perfect for taking burst shots. 

Now we are at the breaking point for this section. As we said earlier, write speed is essential when taking pictures fast. So, the Extreme Pro has a write speed of 90MB/s and is capable of taking a lot of sequential shots

Winner: Extreme Pro

Transfer Speed

Transfer or read speed is different for these two memory cards. The maximum read speed of the SanDisk Extreme is 150 MB/s. SanDisk Extreme Pro’s maximum read speed is 170 MB/s

So, these two memory cards are very fast for transfer speeds. You need to consider the host device’s ability to reach such speed

But, the speed itself varies from card to card. Many factors can impact speed, such as capacity, host device, card reader, etc. However, the Extreme Pro memory card is generally faster in transfer speed since it can reach 170 MB/s.

Winner: Extreme Pro

Video Speed

Video speed classes enable higher video resolutions. For example, a video speed class highlights features supported by the card, such as multiple video streams, and 4K, or 8K content

Video ClassMinimum Write Speed
V6 6MB/s
V10 10MB/s
V30 30MB/s
V60 60MB/s
V90 90MB/s

The Sandisk Extreme and Extreme Pro have the same video speed class – V30. The V30 rating means you are guaranteed a minimum speed of 30 MB/s. Therefore, you can use these cards to record high-resolution videos, such as HD and 4K videos. 

Winner: Draw


The SanDisk Extreme boasts that it is tested and built for harsh conditions. It means it can endure water, temperature, shocks, and x-ray. The same goes for the SanDisk Extreme Pro. Therefore, if you choose any of these memory cards, you can count on them for any type of adventure.

Memory Card Types

These are three basic card types that are common today: 

  1. SD (Secure Digital)
  2. SDHC (Secure Digital High Capacity
  3. SDXC (Secure Digital Extra Capacity)

SD cards support up to 2GB of capacity. SDHC cards are most commonly used and support from 4GB to 32GB. SDXC cards support capacities greater than 64GB, up to 2TB. 

Devices that support SDXC cards also support SDHC and SD cards. However, if your device supports SDHC cards, you might not be able to use SDXC cards.

Luckily, the SanDisk Extreme and Extreme Pro are both SDXC cards meaning you can use them on a vast range of devices. 

Winner: Draw

Specification Numbers: What Do They Mean

Memory cards have standardized speed ratings commonly known as “Speed Classes.” There are Speed Class, UHS Speed Class, and Video Speed Class. 

Both the Extreme and Extreme Pro cards are UHS-I, Class 10, U3, and V30. Let’s find out what these labels mean! 

Class 10

There are four SD classes – Class 2, Class 4, Class 6, and Class 10. The number next to the word indicates the minimum write speed in megabytes. Read speed varies from card to card and is generally faster than write speed.

Speed ClassMinimum Write SpeedUsage
Class 2 (C2)2 MB/sSD video recording
Class 4 (C4)4 MB/sHD Ready video recording (720p)
Class 6 (C6)6 MB/sFull HD video recording (1080p)
Class 10 (C10)10 MB/sFull HD video recording and image recording at the same time

SanDisk Extreme and Extreme Pro fall into Class 10 which means they have a minimum write speed of 10 MB/s.

Winner: Draw

V30 Video Write Speed

The newest speed class for memory cards is Video Speed Class. It shows if a memory card is capable of distributing VR content, high resolution (4K or 8K) videos, video streams, etc. 

Video Speed Class Minimum Write Speed 
Video Speed Class 6 (V6)6 MB/s
Video Speed Class 10 (V10)10 MB/s
Video Speed Class 30 (V30)30 MB/s
Video Speed Class 60 (V60)60 MB/s
Video Speed Class 90 (V90)90 MB/s

This video class can utilize UHS-I and UHS-II bus interfaces. However, the memory cards in our comparison can utilize only UHS-I.

Winner: Draw

U3 Data Transfer Speed

The standard UHS classes are marked with Arabic numerals, most often 1 and 3. UHS 1 supports a minimum write speed of 10MB/s. UHS 3 supports at least 30Mb/s. You recognize this mark on the card by the letter U in which the number 1 or 3 is written.

Speed Classes Comparison
Speed Classes Comparison

The latest memory cards usually use UHS Speed Class rather than the Speed Class. It is because it shows the capability of recording high-resolution videos. For example, if you want to record 4K videos, you need a U3 memory card.

UHS Speed ClassMinimum Write SpeedUsage
UHS Speed Class 1 (U1)10MB/sReal-time HD video recording, large files
UHS Speed Class 3 (U3)30MB/s4K video files

The UHS bus interfaces can further show how advanced the memory card is. There are two types of UHS bus interfaces.

UHS bus interfaceTheoretical Maximum Transfer Speed
UHS-Iup to 104MB/s
UHS-IIup to 312MB/s

The UHS-I interface can be utilized by U1 and U3 memory cards. However, they can’t utilize the UHS-II. Unfortunately, each memory card in our SanDisk Extreme vs Extreme Pro battle supports only UHS-I. 

Winner: Draw


The price depends on the card’s capacity. The price of SanDisk Extreme cards ranges from $9.99 to $59.99. 

SanDisk Extreme Pro cards range from $12.99 to $399.99.

The SanDisk Extreme is significantly cheaper than the Extreme Pro version. If we compare the two of the same capacity, we can conclude that it is more affordable to get the Extreme version. 

For example, a 128-GB Extreme model generally costs $22.99. At the same time, a 128-GB Extreme Pro model generally costs $44.99, which is almost twice as much. 

Even though the Extreme Pro is a bit faster and offers more capacity, it seems it is not exactly worth twice as much.

In order to conclude this Sandisk Extreme vs Extreme Pro battle, we will highlight their best features. 

If you need a memory card capable of storing HD and 4K videos, the SanDisk Extreme might be a perfect choice for you. With 150 MB/s max read speed and 70 MB/s max write speed, it provides a great experience. If you are okay with the price, then the SanDisk Extreme is the better choice for you. 

UHS-I and V30 video memory cards, like the Extreme version, are specifically designed for continuous recording. So, they are perfect for cars, surveillance systems, and all other applications that require endurance due to constant shooting.

However, the SanDisk Extreme Pro could be the right choice if you prefer higher card speeds. With a max write speed of 90 MB/s and a max read speed of 170 MB/s, it provides an even better experience than the Extreme version. 

Finally, if storage space is the main indicator for you, you should choose the Extreme Pro model. This card provides additional storage for those who need more memory space. So, you can choose capacities up to 1TB.
