Sandisk Ultra Plus Read Write Speed

By | 10/11/2022

The SanDisk Ultra and Ultra Plus cards are pocket-friendly SDXC cards that will offer you decent functioning for nearly all mutual digital photographic camera systems except for the actually enervating ones like the medium format cameras where the uncompressed raw files go over 100MB each.

The heavier your raw files are, the slower these cards will perform. They cannot handle 4K video recording either. That said, they tin can both practice 1080p really well. Unless you are doing a lot of bracketing or using the outburst style often, you won’t observe much of a difference when shooting stills either.

The write speed on the Ultra is from 27 – 51MB/south and on the Ultra Plus information technology is effectually 42 – 62MB/south.

This is plenty for most cameras, all the fashion up to full-frame ones where the raw files hover around the 40-50MB mark. This is also enough for the almost enervating 1080p video applications. Here’s how they compare to each other:

Specification SanDisk Ultra SanDisk Ultra Plus
Sequential Write 27 – 51 MB/s 42 – 62 MB/southward
Sequential Read ~99 MB/s ~99 MB/s
Max Chapters Upwardly to 256 GB Up to 256 GB
C Rating C10 C10
U Rating UHS 1 UHS 1
V Rating V10

Let’s put these numbers in terms of mutual real-world uses.

The Movie house 4K setting on the Catechism 5D MK4, at a resolution of 4096 ten 2160p, is recorded at 500 Mb/s. So in this case, the camera needs to transfer data at a constant rate of 62.5MB per 2d (500/8).

Neither the Ultra nor the Ultra Plus tin handle this speed, and then they can’t do 4K. For that, you need to invest in the Farthermost or the Extreme Pro SD cards from SanDisk.

Allow’due south put these numbers in terms of mutual real-globe uses.

The Cinema 4K setting on the Canon 5D MK4, at a resolution of 4096 x 2160p, is recorded at 500 Mb/s. So in this example, the camera needs to transfer data at a constant rate of 62.5MB per second (500/8). Neither the Ultra nor the Ultra Plus can handle this speed, so they tin can’t practise 4K. For that, you need to invest in the Extreme or the Farthermost Pro SD cards from Sandisk.

Some other bottleneck that tin happen with slow cards is when yous are shooting on burst mode for photography.

For instance, the Canon 5D MK4 creates raw files of most 39.5MB and has a burst charge per unit of 7FPS. So, in one second, it can shoot upwardly to vii frames each of about 39.5MB. This ways 276.5MB of data needs to exist moved to the card immediately and so that the internal memory cache of the photographic camera can exist cleared up to have more than outburst mode shots.

The Ultra Plus is the faster of the two cards we are comparison today. With a write speed of from 42 – 62MB/s, it volition need about 4.5 seconds to store what the camera shot in ane 2d. So you will take to expect several seconds for the internal retentivity cache to be freed up plenty to let lose another flare-up of shots.

In such a case, the SanDisk Extreme or Farthermost Pro with write speeds of nearly 89MB/south and 98MB/due south respectively, are the ideal option of cards to take within your photographic camera. If you are shooting 4K at higher bitrates and thus producing actually large files, you will also do good from the larger 1TB maximum chapters of the Extreme Pro.

However, these are special scenarios that most coincidental shooters don’t come across. So if yous are not going to be shooting 4K and don’t demand to use the burst mode a lot, y’all tin can save some money past going for the Sandisk Ultra or the Ultra Plus.

Let’s look at some of the terminology commencement before we have an in-depth look at our SD carte contenders.

Why Trust Me?

As with all of the camera-related articles I create, I have poured countless hours of enquiry into it to make certain you take all the information you need to make the best decision.

I’ve been a professional filmmaker and photographer since 2018 and have been lucky enough to work on projects all over the earth with brands such as Alaska Airlines,, Prague Tourism, Visa, Airbnb, and many more. If yous’re curious to encounter the full list of companies we’ve worked with, just head over to our

Work With U.s.a.


Although I use other memory card brands too, SanDisk SD cards make upwardly the majority of the retention cards I have. I have used both the SanDisk Farthermost and Farthermost Pro in a variety of different photography and filmmaking situations and it’s from these experiences that I recollect I’g in a good position to help you lot figure out which one is best for yous.

Most importantly, I’m just a message abroad. So, if y’all take whatsoever questions, just leave a comment below, email me at

P.S. I reply every question that is sent 🙂

SD Card Terminology

Take a look at
this page by the SD Association
(the governing torso of the SD card technology standard) to know more about how the diverse speed classes work.

Or merely read on to get a brief overview.

Speed Form

Denoted by a number inside a C, this is the first scale to have been used to classify SD cards based on their minimum write speed. Nearly cards volition exist rated at C10 these days and that only ways that you can wait the performance to stay higher up 10MB/due south in all scenarios.

UHS Speed Grade

Denoted by a number inside a U. This is more recent than the C numbers.

U1 means 10MB/s minimum and U3 means 30MB/southward minimum. This nomenclature was released with the UHS Bus IF family of products. This is comparatively newer technology where at that place are 3 types – UHS I, Two, and Iii, denoted simply past the Roman Numerals I, II and III on the sticker.

These numbers simply denote the transfer speeds a device is capable of.

UHS I devices can reach write speeds of up to 104MB/s. This engineering science maxes out the single row of data pins that most SD cards have.

To get around this bulwark, a 2nd row of data pins were introduced and the UHS-II and UHS 3 standards came into existence. UHS-2 can go up to 312MB/s and UHS III tin go up to 624MB/southward. To know more, you can visit the link below to get to the UHS page on the
SD Association’s official website.

Video Speed Grade

Denoted by a number beside a 5. This scale is the latest and it is intended to replace the older nomenclature systems. Information technology starts from V6 for 6MB/south and goes to V10 (10MB/s), V30 (30MB/south), all the way up to V90 (90MB/s).

You tin can wait at the
chart from the SD Association
to get a better sense of how these 3 speed-classification systems line up with real-world operation and video recording usage.

Sequential Read/Write

Your photographic camera writes data to the card in a sequential manner where all the data is lined upwards in a queue and they are written to physical data blocks on the menu that are correct next to each other. You are using sequential read/write when y’all write large video files to the memory menu, when video is beingness played back, and when you are taking photographs.

For all of you photographers, sequential read/write speed has the biggest impact when y’all are shooting flare-up fashion. Equally I covered higher up, the faster the sequential read/write speed, the better and faster it will perform when using burst fashion.

In this article, all the speeds mentioned are sequential write and read speeds.

Random Read/Write

As the proper name suggests, Random Read and Write is when at that place is no sequence in which the data is being written or read.

Considering the information being read or written is scattered in dissimilar places, the overall speed of transfer slows downwardly.

This is what happens when y’all desire to transfer many files, folders, and subfolders all at the aforementioned time and you notice that your transfer speed is slower than if you lot were moving the aforementioned amount of data in a single file or ii.

Now that you understand all the terms, permit’s jump into the comparing between the Sandisk Ultra and Sandisk Ultra Plus.

SanDisk Ultra Overview

This is the cheapest SanDisk card you tin can purchase and nonetheless information technology delivers excellent quality and performance. The only difference between the Ultra and the Ultra Plus retention card is the maximum write speed.

The Ultra lags by virtually 11MB/s with a peak terminate write speed of 51MB/southward compared to the 62MB/s of the Ultra Plus.

SanDisk Ultra vs SanDisk Ultra Plus


  • Ultra is cheaper than Ultra Plus
  • Ultra offers the same read speed of about 99MB/south as the Ultra Plus, which translates to 128GB transferred in well-nigh 22 minutes


  • Has a slightly slower write speed than the Ultra Plus
  • Cannot handle 4K video recording


The Sandisk Ultra Plus’due south principal difference to the Sandisk Ultra is in the write speed. which is near 11MB/s college at at the top cease with write speed of 62MB/s vs 51MB/due south on the Ultra.

This deviation is important enough to give it a V10 rating but it doesn’t make that much of a real-world difference when it comes to 1080p video recording functioning or during photography. Both the Ultra and the Ultra Plus piece of work well for 1080p video, where the data charge per unit seldom goes north of 25MB/s (180Mb/s).

For those of you who don’t want to spend the extra coin for the Sandisk Farthermost but desire to have a carte that performs well, this is one to consider.

The extra write speed volition give yous slight improvements when it comes to burst mode shooting and bracketing. If that doesn’t matter though, merely relieve your coin and buy the SanDisk Ultra instead.

SanDisk Ultra Plus vs Ultra


  • Ultra Plus faster than the Ultra by 11MB/s at its tiptop stop write speed, pregnant slightly better performance during outburst mode and bracketing


  • The Ultra Plus is more expensive
  • Cannot handle 4K video recording

SanDisk Ultra vs Ultra Plus Comparison

Between the Sandisk Ultra and the Sandisk Ultra Plus, the Sandisk Ultra is the clear winner for those who are looking for the best value. Although the Sandisk Ultra has a slightly slower sequential read/write speed (slower by about 11 Mb/s), this speed difference won’t make much of a difference in real earth shooting.

At its price point, the Sandisk Ultra is a cracking choice for those who desire to get started in photography, are non shooting 4k video, and won’t need the fastest functioning when using burst mode for photography.

Hither’s some data to give you a better thought why the slight speed heave yous get from the Ultra Plus is probably not worth the extra money.

A mid-range crop sensor camera like the Catechism 550D can shoot at 3.7 frames of about 24MB each with a cache that can hold up to six frames. That’s a 144MB of data that will have 2.8 seconds to exist fully transferred to the Sandisk Ultra. In comparison, it will take 2.iii seconds to transfer to the Ultra Plus. This departure is minimal and you most likely will not notice it in a real-world setting.

Maximum Shot/Write Speed

As I have gone over, the Ultra Plus has a slightly faster maximum top cease write speed of 62MB/south versus the 51MB/southward of the Ultra. This means that theoretically y’all’ll get better functioning when using flare-up style and bracketing mode, but realistically, yous won’t discover much difference.

Maximum Transfer/Read Speed

When information technology comes to transfer/read speed, the SanDisk Ultra Plus equally a faster read speed of ~129 MB/south vs the 99MB/s found with the Ultra.

Read speed only matters when you are transferring your files out of the menu and will make the biggest difference if you’re transferring big file sizes. If you’re only shooting photos and videos casually, either the Ultra or the Ultra Plus will serve you fine.

If at any point you start taking large amounts of photos in RAW format, though, it might make sense to upgrade to either the Sandisk Farthermost or Sandisk Extreme Pro for the fastest transfer speeds.


All Sandisk SD cards are waterproof, temperature proof, shockproof, and X-ray-proof. In my years of using them, I accept never had annihilation to mutter about. They have gone through unlike conditions conditions, airport security scanners and diverse cameras. The cards have e’er performed consistently.

Alternatives to SanDisk Ultra and Ultra Plus

SanDisk Farthermost

The Sandisk Extreme is office of the company’s Farthermost line of cards that is targeted to the professional marketplace. It is faster than the Ultra by a significant corporeality and tin shoot 4K video. Because of its faster speeds, it volition also give you much meliorate performance when shooting in burst manner.

For a comparison between the
Sandisk Extreme versus Extreme Pro review.


  • Faster write speed of about 89MB/s versus the 62MB/south of the Sandisk Ultra. This makes it a good fit for cameras with heavy RAW files of 30MB+ and for bracketing or shooting in burst style
  • Rated at V30, meaning it can be used for 4K video recording
  • Higher read speeds of effectually 153MB/s versus the 99MB/s of the Sandisk Ultra and Ultra Plus. To requite y’all an idea 128GB of files will transfer nether 14 minutes with the Sandisk Extreme


  • Expensive compared to the Ultra and the Ultra Plus
  • But goes up to a capacity of 256GB, the aforementioned as the Ultra or Ultra Plus
  • Non supported by some other cameras

SanDisk Extreme Pro

The Farthermost Pro is the top-of-the-line retentivity bill of fare from Sandisk and gives you lot the fastest read and write speeds. Like the Sandisk Extreme, yous can also tape 4K videos and it performs very well for burst mode or subclass mode photography.

For a comparison between the
Sandisk Extreme versus Extreme Pro review.


  • Faster write speeds of 98MB/s versus 89MB/southward of the Farthermost. It gives you slightly better performance for bracketing and flare-up manner photography
  • Very high read speeds of virtually 176MB/south which will transfer 128GB of files in near 12 minutes versus the xiv minutes with the Sandisk Extreme
  • Rated at V30, meaning information technology can be used for 4K video recording
  • Goes up to 1TB, which is nice for large amounts of 4K video files or RAW photos


  • The most expensive UHS I SD bill of fare from Sandisk
  • The higher price may non be justified if your photographic camera cannot perform at the same speed
  • Not supported past some older cameras


The Sandisk Ultra and Ultra Plus are meant for mass-market consumer use and are specced accordingly.

If you are just getting started, need a backup card, or want to buy a big capacity similar 256GB without spending too much, these cards are your platonic pick. They will do perfectly fine when shooting stills or recording 1080p video.

Yes, you lot volition confront some performance issues when dealing with large data rates such as when shooting in flare-up style or bracketing but otherwise, you won’t notice whatever problems even on newer total-frame or mirrorless cameras.

Nonetheless, the big downside is that you lot will not be able to shoot 4K video on either of these cards. And they take noticeable slow performance if your camera produces large heavy raw files.

If you lot want to shoot 4K and accept a smoother time using burst style and bracketing on your camera, you are ameliorate off buying the Sandisk Extreme or Extreme Pro memory carte as they are not that much more expensive in the yard scheme of things.

Another thing to keep in mind is if y’all are thinking about upgrading your photographic camera any time soon. New cameras these days have larger and larger RAW files, have faster outburst modes and offer 4K and higher video recording features, so it might make sense to upgrade memory cards right away.

That’s information technology for the Sandisk Ultra and Ultra Plus SD card comparison and I promise I was able to help you make a determination.

Let me know which card yous went for in the comments beneath. If you already own one or more of them, drop a comment with your experience with them and why you chose to buy the ones you have.
