SanDisk Nintendo Switch microSDXC Card vs. Ultra vs. Extreme vs. Extreme Pro

by Kevin Chen

In addition to an officially licensed microSD card, SanDisk has several memory cards that are compatible with the Nintendo Switch and Nintendo Switch Lite with the SanDisk Ultra, SanDisk Extreme and SanDisk Extreme Pro. So, which one of these is best suited for the gaming systems?

You can find out in this comparison guide.

Quick Summary

Although the SanDisk Extreme Pro has the fastest read speed out of this group, the performance for all four cards should be the same as the Nintendo Switch and Nintendo Switch Lite can only support read/transfer speeds of up to 95 MB per second.

We recommend picking up either the officially licensed SanDisk Nintendo Switch microSDXC Card or the SanDisk Extreme Card as these two are more affordable than the SanDisk Extreme Pro while offering the same performance at loading games on the Switch and Switch Lite.

The writing speeds between the official Switch microSDXC Card, SanDisk Extreme and SanDisk Extreme Pro are also identical at capacities of at least 128GB.

Although the SanDisk Ultra is the cheapest out of this group, the card has unknown writing speeds, which could lead to slower performance when it comes to certain actions, in addition to having a shorter warranty coverage period when compared to the other three memory cards.

Nintendo Switch Memory Card Recommend Specs

Nintendo recommends that you use a memory card that has a bus interface of UHS-I.

Although you can also use UHS-II memory cards with your Switch and/or Switch Lite, your speeds will be limited to the UHS-I specifications. Thus, there is no reason to get an UHS-II memory card over an UHS-I memory card for your Switch system.

The other recommend specification is the read/transfer speed as Nintendo suggests the specs to be at least 60 MB per second. You will get a better gameplay experience, such as better load times, with higher read speeds.

However, both the Switch and Switch Lite only supports a maximum reading speed of up to 95 megabytes per second. So, even if you have a memory card with a much faster speed, you will be bottlenecked to 95 MB/s.

Thus, there is no point in getting a memory card that has a read/transfer speed that is significantly above 98 MB.

Capacity Options

All four of the Switch compatible memory cards in this versus guide are available in capacities of 64GB, 128GB, 256GB and 512GB. The SanDisk Ultra also offers 16GB and 32GB options.

The SanDisk Extreme and SanDisk Extreme Pro are available in 32GB as well as 1TB.

If you download a lot of games and/or downloadable content, then we recommend getting the biggest capacity you can afford for the extra convenience of not having to delete anything and/or swap out cards if you ran out of free space.

Ultra High Speed Bus Interface

All of the capacities for both cards in this versus guide use the UHS-I interface, which provides bus speeds of up to up to 104 MB per second.

Class

Both micro SD cards from SanDisk also have the same speed class of 10. This means that the flash memory is capable of at least 10 MB per second when it comes to sequential writing speed.

UHS Speed Class

U1 is another classification for a memory card that can achieve a minimum sequential write speed of 10 MB per second. Aside from the 16 GB version of the older SanDisk Ultra, all the other size options have been rated for the U1 UHS Speed Classification.

Application Performance Class

Application Performance Classification is a set of speed requirements that need to be met in order run applications smoothly on a microSD card. All of the capacities for both the new and old SanDisk Ultra microSDs have been rated at A1, which mean the cards are capable of a minimum sustained write speed of 10 MB per second, minimum random read speed of at least 1500 IOPS and a minimum random write speed of at least 500 IOPS.

Read Speed

With the new Ultra microSDXC cards, SanDisk used proprietary technology to add more read speed to go beyond the aforementioned UHS-I’s limit of 104 MB per second to reach 120 MB per second.

You can take a look at the read speed specifications for each capacity option below:

SDSQUAR SanDisk Ultra microSD:

16 GB: Up to 98 MB per second
32 GB: Up to 98 MB per second
64 GB: Up to 100 MB per second

Lexar microSD Cards: 300x vs. 663x vs. 667x vs. 667x Video vs. 1000x vs. 1066x vs. 1800x

by Kevin Chen

Lexar Professional recently released the 1066x microSD Card. So, how does the new series compare to the 300x, 663x, 667x, 667x Video, 1000x and 1800x?

You can find out in this versus guide between these seven cards.

Quick Summary

The Lexar Professional 1800x microSDXC Card has the best general reading and writing speeds of the group. It also has the best video speed class. If you are planning to use your card for shooting video, especially 8K, then the 1800x is the best choice.

The Lexar microSDXC cards with a V30 or V60 classifications are also great for shooting videos of up to 4K in resolution.

If you are planning to use your card to run Android applications, then you should get the Lexar cards that have the A2 classification. These include the 512GB 663x, 128GB 667x, 256GB 667x, 512GB 667x, 64GB 1066x, 128GB 1066x and 256GB 1066x cards.

Speed Classifications

There are several speed classifications, which can be quite confusing.

Class

The first is class, which represents the minimum write speed of a micro SD card. All the Lexar cards in this comparison guide are Class 10, meaning that the products have a minimum write speed of at least 10 MB per second.

UHS Speed Class

Next up is the UHS Speed Class, which also shows the minimum write speed of a card.

The 300x series, as well as the 32GB versions of the 663x and 1066x, are classified as U1, meaning that the cards have a write speed of at least 10 MB per second.

The rest of the cards are classified as U3 since these products have a write speed of at least 30 MB per second.

Video Speed Class

Video Speed Class measures the sustained writing ability of a memory card, which is important for continuous video recording.

The 300x series don’t have any classification, so it is not suitable for video recording.

The 32GB versions of the 663x and 1066x are V10 as these microSD cards are capable of 10 MB per second.

The bigger capacities of the 663x and 1066x, as well as the 667x and 667x Videos series, are V30 as these memory cards are capable of writing at least 30 MB per second.

The Lexar 1000x series are classified as V60 with the capability of writing 60 MB per second.

Last but certainly not least is the 1800x with V90, which means that the cards are write at least 90 MB per second.

For video shooting, V90 is the only option if you are shooting 8K videos. V30 and above are recommend for 4K video shooting while V30 and below are suitable for 1080p, 720p and standard resolution video shooting.

Application Performance Class

Some of the cards also have an Application Performance Class, which measures the sustained write speed in addition to random read and write speeds. This specification is used to see how fast and Android apps can be launched in addition to how fast they can perform on micro SD cards.

The 32GB to 256GB versions of the 663x along with the 64 GB version of the 667x and 32 GB version of the 1066x are classified as A1, which means that these cards have a sustained write speed of at least 10 MB in addition to a random read speed of at least 1500 IOPS and a random write speed of at least 500 IOPS.

The 512GB version of the 663x, 128GB to 256GB versions of the 667x as well as the 64GB to 256GB versions of the 1066x are classified as A2. This mean that these memory cards can sustain a writing speed of 10 MB minimum in addition to a random read speed of 4000 IOPS minimum and a random write speed of 2000 IOPS minimum.

So, if you want best speeds for Android apps, make sure you get the A2 Lexar microSDXC cards.

You can take a look at the speed classifications for each capacity below:

8GB 300x: Class 10, U1

by Kevin Chen

PNY has several very similar microSDXC cards with the Elite, Elite Performance, PRO Elite and Elite-X. So, which of these flash memory cards best fit your needs?

You can find out in this comparison guide.

Quick Summary

When it comes to general read speed, the PNY Elite microSDXC Cards, PNY PRO Elite microSDXC Cards and PNY Elite-X microSDXC Cards have the same performance. The PNY Elite Performance microSDXC Cards read slightly slower than the others.

The PNY PRO Elite is the fastest out of this group when it comes to launching applications and app performance. The PNY Elite-X comes in second at running software on smartphones and tablets.

For video recordings, only the PRO Elite and Elite-X can sustain a capture rate of at least 30 MB per second.
