What’s the Difference Between Sandisk Ultra vs Extreme?

SanDisk Ultra and SanDisk Extreme are both memory cards from the same brand – SanDisk, now part of Western Digital.

One of the biggest differences lies in how they record video. If you’re recording video at 1080p HD, you can use either one. However, to record 4K/UHD video at a constant speed, you need a SanDisk Extreme memory card.

For higher capacity, you’ll need to upgrade to the SanDisk Extreme Pro. This model is available in capacities ranging from 32GB to 1TB. But we won’t be talking about the Extreme Pro in this article.

So, back to SanDisk Ultra and SanDisk Extreme. I’ve already mentioned the difference in video recording, but what about photography?

Well, if you have a high-resolution camera or use the continuous shooting mode often, you should consider the SanDisk Extreme.

Now that you know the broad differences, let’s get more into the details. Please keep in mind that I’ll be talking about the current generation of memory cards, produced approximately from 2022.

You may encounter SanDisk Ultra and SanDisk Extreme cards that don’t match the specs mentioned here – this happens with older generations.

Now that we’ve got that out of the way, let’s see which one is right for you.

What is SanDisk Ultra?

Ultra is the mid-range line of SanDisk SD memory cards. These cards are mainly designed for smartphones and entry level cameras because they have a smaller capacity. Therefore, you would run out of space fairly quickly with a high-resolution camera.

Another limitation of the Ultra line is that it’s not fast enough to handle 4K and up video recording or the higher burst rates that come with professional cameras.

On the upside, it’s exactly because of its target market that these memory cards are widely compatible and very affordable.

You can find SanDisk Ultra memory cards in multiple formats – SanDisk Ultra SD, SanDisk Ultra microSD, and SanDisk Ultra microSD with SD adapters.

The microSD cards with an SD adapter have the broadest range of capacities. In fact, they’re available in 16GB, 32GB, 64GB, 128GB, 200GB, 256GB, 400GB, 512GB, and 1TB.

Each format has a different range of capacities. Currently, the highest-capacity Ultra model is the newly released SanDisk Ultra micro SDXC 1.5TB.

All models support Full HD video (1080p) and offer transfer speeds up to 120 MB/s. It’s worth noting that this speed is only achieved with the newer models and higher capacities – an old 16GB Ultra card, for example, will be slower.

Plus, they are compatible with microSDHC and microSDXC devices. Here’s a full list of models – some are from the old generation, but you might encounter them in second-hand shops.

• The Ultra microSD UHS-I cards are available in 16GB, 32GB, 64GB, 128GB, 512GB, 1TB, and 1.5TB.
• The Ultra microSD card for Chromebook is available in 64GB, 128GB, 256GB, 512GB, and 1TB.
• Then, you’ll find the Ultra SDHC/SDXC available in 32GB, 64GB, 128GB, 256GB, 512GB, and 1TB.
• The Ultra SDHC UHS-I and SDXC UHS-I cards are available in 16GB, 32GB, 64GB, 128GB, 256GB, 512GB, and 1TB.

Regardless of which one of these cards you choose, you may need a memory card reader to transfer the photos and video files to your computer if it doesn’t have an SD slot.

What is SanDisk Extreme?

Looking at SanDisk memory card options, the SanDisk Extreme is the next step after the SanDisk Ultra. However, it’s still just an intermediate step because the top-of-the-line SanDisk memory card is the Extreme Pro.

So, keep an eye on the ‘Pro’ label when you’re purchasing a SanDisk Extreme card, because confusing the Extreme with the Extreme Pro could lead to unnecessary expenses.

If you don’t need the extra performance from an Extreme Pro, you’d be paying for a more expensive product for no reason – but let’s get back to the Extreme line.

SanDisk Extreme memory cards are more powerful than SanDisk Ultra ones because they offer faster read and write speeds. So, they support 4K video recording and handle burst mode even when shooting in raw format.

Another advantage over the SanDisk Ultra is that the SanDisk Extreme is also available in CompactFlash format. This is on top of the microSD and SD cards you can find in the Ultra line.

However, it’s not all positive, as it doesn’t yet reach the 1.5TB maximum capacity, unlike the Ultra line. The SanDisk Extreme is currently available up to 1 TB.

SanDisk Extreme SD UHS-I is available in capacities of 32GB, 64GB, 128GB, 256GB, 512GB, and 1TB.

SanDisk Extreme microSD for Mobile Gaming is available in 64GB, 128GB, 256GB, 512GB, and 1 TB capacities.

SanDisk Extreme CompactFlash comes in 32GB, 64GB, 128GB, and 256 GB capacities.

Sandisk Ultra vs Extreme: How Do They Compare?

To decide whether you need an Ultra or an Extreme memory card, compare them by the most important specs.

1. Read/Write Speeds

One of the main differences between Sandisk Ultra and Extreme is the write speed. A SanDisk Ultra card typically offers read speeds of 120-150MB/s, but the write speed is much lower and not always specified.

On the other hand, SanDisk Extreme cards have faster overall performance. The read speed can reach up to 190 MB/s, and the write speed up to 130 MB/s, depending on the capacity and model.

Consider that write speed refers to how fast photos and videos are recorded on the card. That’s why the SanDisk Extreme, with its faster write speed, is better for tasks like burst photography and 4K video recording.

In conclusion, in terms of read and write speeds, the SanDisk Extreme is the clear winner.

UHS Class – Bus Speed

The UHS class defines the bus interface and the speed class; together, they influence the performance.

The UHS speed class is marked with a ‘U’ followed by a 1 or 3. A U1 guarantees a minimum write speed of 10 MB/s, and a U3 guarantees at least 30 MB/s.

The UHS bus interface is indicated with Roman numerals. The UHS-I has a theoretical maximum transfer speed of 104 MB/s, and the UHS-II increases this to 312 MB/s.

In practice, actual speeds can exceed these values due to manufacturer-specific optimizations, especially for read speed.

Generally speaking, there’s no difference between SanDisk Ultra and SanDisk Extreme in terms of bus interface, as both mainly use UHS-I. Instead, higher-end models like the SanDisk Extreme Pro use UHS-II.

However, the main difference between SanDisk Ultra and SanDisk Extreme in this regard is that Ultra cards are typically rated U1, while Extreme cards are U3. This is another reason why Extreme is better suited for high-performance tasks.

Speed Class

The speed class is denoted by a circular “C’ followed by a number that indicates the rating. Most new cards are marked as C10 (Class 10), and it’s not something you need to particularly concern yourself with.

The speed class guarantees the minimum write speed in the older, standard speed rating system, while the U-class was developed for modern use and it’s much more relevant today.

However, the C-class works to ensure compatibility with older devices. You can come across these variants:

• C2 = 2MB/s
• C4 = 4MB/s
• C6 = 6MB/s
• C10 = 10MB/s

However, the C10 is the current standard across virtually all SD and microSD cards in both SanDisk Ultra and SanDisk Extreme.

Video Speed Class

The video speed class is the most modern performance system, and it refers to the sequential write speed. As you can imagine by the name, this is only relevant for video recording – if you only do photography, you don’t have to worry about the V-class.

Video speed class can be V10, V30, V60, or V90 corresponding to 10MB/s, 30MB/s, 60MB/s, and 90MB/s respectively.

This classification directly relates to the video resolution and bitrate that the card can reliably support.

Most UHS-I cards only support up to V30, while higher ratings (V60 and V90) are typically found in UHS-II, which, as we’ve seen, corresponds to the Extreme Pro line.

SanDisk Extreme cards are usually rated V30 (30 MB/s), which is enough to record 4K video. Instead, SanDisk Ultra cards are either V10 or lack a V rating, which is why they’re only suitable for Full HD (1080p) video recording.

In this category, SanDisk Extreme is clearly superior to SanDisk Ultra.

2. Storage Capacity

Storage capacity is what most people consider when buying memory cards, as it indicates how much data the card can hold. Of course, you now know this isn’t the only relevant value.

Both the SanDisk Ultra and the SanDisk Extreme are available in different storage capacities, depending on the memory card type (SD, microSD, or CF).

SanDisk Ultra has the advantage of micro SD cards, offering a broader range. You can find SanDisk Ultra microSD cards from 16GB up to 1.5TB, making them the highest-capacity option currently available.

SanDisk Extreme microSD cards have also expanded their range in recent years, and they’re now available from 32GB to 1TB. While the Highest capacity is smaller than the Ultra one, it’s enough for most users.

Remember that it’s always possible to buy a SanDisk Ultra microSD card with an SD adapter if you need 1.5TB capacity, but your device only supports SD cards.

When it comes to SD cards, both the Ultra and the Extreme lines offer similar capacity ranges. Generally speaking, you can find them from 32GB up to 512GB, and in some cases, 1TB.

Compact Flash cards are exclusive to the Extreme line, but because it’s mostly an outdated format, SanDisk isn’t expanding their 32GB, 64GB, 128GB, and 256GB capacities.

3. Storage Format

SanDisk memory cards come in three main formats: SD, SD High Capacity (SDHC), and SD Extended Capacity (SDXC). This is important because it affects both compatibility and the card’s default file system.

SD cards are formatted with FAT16, but they’re very rarely sold as their capacity ranges from 2GB to 4GB, which is largely surpassed by even the smallest modern cards.

SDHC cards use FAT32 and cover capacities up to 32GB. These are not compatible with older devices that support only SD cards, but most devices from 2008 and later will work with SDHC formats.

SDXC cards use the exFAT file system and support capacities up to 1.5TB, as in the microSD card we talked about. These cards require devices that explicitly support the SDXC format, which most current devices do.

Both SanDisk Ultra and Extreme cards can be SDHC or SDXC according to their storage capacity.

The main practical difference is choosing between FAT32 and exFAT, as FAT32 limits individual file sizes to 4GB. Using exFAT formatting removes the 4GB limit and offers faster performance for larger files.

For modern photography and 4K/8K video, SDXC/exFAT is the recommended format. If you use smaller files or have an older device, an SDHC/FAT32 will suffice.

4. Durability

Both the SanDisk Extreme and Ultra cards are built to the same high-quality standards and undergo rigorous testing to ensure reliability. According to SanDisk, their cards are designed to withstand:

• Immersion (1m) in salt or freshwater for up to 72 hrs.
• Extreme temperatures from -13 to 185°F (-25 to 85°C).
• Shock up to 500Gs.
• Drops up to 5 meters and can even be run over by a vehicle.
• Exposure to airport X-rays.
• Strong magnetic fields without data loss.

These durability features make SanDisk microSD and SD cards among the most trusted in the industry.

5. Cost

Price is often the deciding factor for users without a specific tech requirement. Generally speaking, the SanDisk Ultra line is more affordable than the SanDisk Extreme line because it offers higher capacities at a lower cost per gigabyte.

So, if you don’t need to record 4K video or higher, a SanDisk Extreme card may be overkill, and a SanDisk Ultra card will usually offer better value for everyday photography and Full HD video.

The only exception for photographers is when you need to use a high burst rate in continuous shooting – here, you’ll also want to invest in a SanDisk Extreme card.

This line is ideal for professional or high-demanding use cases, providing higher sustained write speeds.

However, if you need even higher performance or a CompactFlash card, you’ll need to look at the Extreme Pro line.

In the end, it comes down to balancing your performance needs with your budget. Hopefully, this guide has given you enough information for you to make the best choice.

What’s The Difference Between SanDisk Ultra Vs Extreme? – Summary

As we’ve seen in this SanDisk memory card comparison, the main difference between the SanDisk Ultra vs Extreme comes down to speed – both in terms of write performance and overall data transfer rates.

The SanDisk Ultra is rated U1, which guarantees a minimum write speed of 10MB/s.

The SanDisk Extreme, on the other hand, is rated U3, meaning it supports a minimum sustained write speed of 30MB/s – making it much better for high-resolution video and demanding tasks.

The sequential write speed is also important in this regard. Ultra cards usually don’t have a V speed rating, while Extreme ones are classified under the V30 video speed class. This ensures consistent 30 MB/s performance, which is especially important for 4K video recording.

The read speed is also different between the two lines. The SanDisk Ultra reaches speeds of up to around 120-150MB/s depending on the version. Instead, the SanDisk Extreme can reach up to 190 MB/s, offering a clear advantage when transferring large files.

It’s worth noting that this is usually a critical point only for professionals who need to download and cull thousands of images – often on a tight deadline.

Aside from the technical differences regarding speed, the next obvious difference is the cost. SanDisk Extreme cards are more expensive, so it’s worth considering if you actually need the extra performance.

For many everyday users, a SanDisk Ultra card is enough, while the Extreme is better suited for professionals and a specific niche of enthusiasts who use burst mode or record high-resolution videos.

Speaking of targets, the SanDisk Ultra is aimed at entry-level users, while the SanDisk Extreme is designed for more advanced use cases.

Ultimately, when choosing between the SanDisk Ultra and SanDisk Extreme, the best option depends on how you plan to use the card.

SanDisk Ultra SD Card vs Extreme for Phone

For smartphone use, a SanDisk Ultra microSD is usually more than enough. Tasks like storing photos, videos, and app data don’t typically require very high write speeds.

However, smartphones keep improving, and it’s now possible to find many models that can record 4K videos – for that, you do need a SanDisk Extreme card.

SanDisk Ultra vs Extreme: Switch

According to Nintendo, using a microSD card with a higher transfer speed will improve the gameplay experience. So, I recommend using a SanDisk Extreme card.

The Nintendo Switch supports microSD, microSDHC, and microSDXC, but requires a system update to use microSDXC.
