The Extreme Plus is the most recent, updated version of the aging Sandisk Extreme range of memory cards, offered as a cheaper, slower version of the Extreme Pro. Although this is a very good card, with very fast read and write speeds, it is about 10% slower than the Extreme Pro in practice, and matches, or even falls slightly behind, the original Sandisk Extreme. Well, each card has its advantage and serves a different purpose. The only thing that can separate these two cards from each other is the buyer’s preference and priorities. SanDisk Extreme Pro The SanDisk Ultra offers a wider range of capacities than the Pro Plus, with lower prices across the board. This is partly owing to its lower U1 speed class, meaning its write speeds aren’t as fast as U3 models, but that’s more of a concern for videographers needing a microSD card for their camera. Where games performance is concerned, read speed is king, and the affordable Ultra can keep pace with pricier cards.

Consider this: if you have been taking pictures with your camera for a while and it comes to a point where you would need to transfer the files to your computer, the SanDisk Extreme Pro’s faster read speeds would cut the waiting time while transferring large photo and video files to your computer.The Extreme Plus offers better performance than the SanDisk Mobile Extreme, but at these levels, we're not seeing the huge jumps in performance that we did with previous generations of cards. For one thing, the Galaxy Note 3 seems to max out at Extreme levels of performance—and remember, this is a phone that records 4K video at 30 frames per second. But even in the PCs, we're seeing incremental steps rather than the huge leaps in write speeds we saw, say, between the Mobile Ultra and Mobile Extreme. That makes me hesitant to recommend this more expensive card over the Mobile Extreme. You would really feel the difference when you are taking multiple burst photos. The SanDisk Extreme Pro will just be faster on taking in the data from the camera’s buffer.

Now, For us to really identify which card has the edge over the other we need to compare some technical specifications and look into which offers value for your money.

There are clear differences between the three cards we have tested today, although for most non-professional uses, you are unlikely to see any difference between the Sandisk Extreme and Extreme Pro. Choosing either of these would be the sensible choice. If you have a choice between a lower capacity Sandisk Extreme Pro, or a higher capacity Sandisk Extreme at the same price point, I would always recommend buying the higher capacity card.

Read Speeds should also be considered especially if you shoot 4k videos with large file size. It indicates how fast your SD Card can transfer files to another computer or storage device. Video recording requires consistent write speeds. This is where you should consider SD Card’s minimum write speeds. This is the rate where your SD Card can consistently accept information from the camera without any ups and downs. If you look at the read speeds for the Sandisk SD Ultra vs Extreme, you find that they show a similar story, at 116 – 153 MB / sec for the Extreme and 90 – 100 MB / sec for the Ultra. It’s only a disappointing result in the Shadow of the Tomb Raider loading test that denies the Evo Select a higher position in this list, though to be fair, its launching speed for the same game is much more competitive with the pricier stuff. It’s still a good bet for those wanting a budget microSD specifically, with the 512GB model being particularly good value right now. Photos cannot be written to the memory card as fast as they can to the buffer, and once the buffer is full, you cannot take any more photos, until space has been freed up on the buffer.Now, you may say that I would not be needing fast saving times when taking pictures, why would I need the Pro model?

The sequential write speed for each memory card refers to the speed at which writing can be maintained over longer time lengths. This is a figure from testing in an R&D lab, and it is not clear from my research exactly what length of time the sequential write speed is measured over, but this is likely to be a few minutes. The SanDisk Extreme Plus microSD card looks virtually identical to other SanDisk microSD cards with its usual gold and red coloring; the only difference is the added “PLUS” text at the top right. Also displayed on the front is the SanDisk branding, class information, and capacity. On the other hand, SanDisk Extreme Pro was catered for high performance devices . The Extreme Pro in some ways is really better compared to Extreme Plus. But, it is a bit expensive compared to Extreme Plus. So, which is better between the Sandisk Ultra or Extreme? From real world testing, it is the Extreme. When combined with the card being available in capacities up to 1TB, and a lifetime warranty, this becomes excellent value for money if you care about your photography.If you are a professional who needs immediate transfer of photos and videos for post-processing, you will need an SD Card with fast read speeds. It’s clear from the specifications and from my testing, that the Sandisk Ultra is significantly below par when compared to the other two models. Although it is the cheapest of the three, it will struggle to cope with recording 4k video and any length of burst shooting. Choosing this model would be a mistake. In this case, the SanDisk Extreme Pro is 5 MB per second faster which is rated at 95 MB per second compared to the SanDisk Extreme Plus that is rated at 90 MB per second. This may not be a lot of difference on paper but believe me, you would thank that extra 5 MB per second in the long run. SanDisk Extreme Pro has a max write speed of 90 MB per second, on the other hand, the SanDisk Extreme Plus has a max write speed of 60 MB per second. If you mostly use your camera to capture photos from outdoor activities or action photography, you should consider getting an SD Card with higher maximum write speeds.
