5An upgrade in READ speed, write speeds vary
By Sporty
The SanDisk Ultra 80MB/s is a new card that replaces the Ultra 40MB/s. The 80MB/s is the read speed only. SanDisk refers to the write speed as Class 10, which means the card maintains at least 10MB/s continuous write, but does not state a maximum write speed. I tested the following Ultra 80MB/s cards: (2) 32GB, 64GB and 128GB and compare with the previous Ultra 40MB/s cards. I use CrystalDiskMark benchmark (5 passes, 1GB random data) and USB 3.0 card reader.

SanDisk Ultra 80MB/s (new version, September 2015)
32GB (1) Read: 94.2 MB/s Write: 43.0 MB/s
32GB (2) Read: 97.7 MB/s Write: 20.9 MB/s
64GB Read: 82.4 MB/s Write: 19.1 MB/s
128GB Read: 97.7 MB/s Write: 38.5 MB/s

SanDisk Ultra 40MB/s (old version, 2014-2015)
32GB Read: 47.8 MB/s Write: 19.9 MB/s
64GB Read: 47.8 MB/s Write: 16.2 MB/s

READ Speed: Ultra 80MB/s cards exceed 80MB/s read speed and are much faster than the old version. This allows fast downloads from the card to your computer when used with a USB 3.0 card reader. Using USB 2.0 it limits the speed to about 35MB/s.

WRITE Speed: Benchmarks can be deceiving! The benchmarks show a big difference in write speed between cards. One 32GB card measured 43MB/s but one from a different source was 20.9MB/s. When writing actual files the write speed varies during transfer. The 128GB card benchmark was 38.5MB/s write, but transferring a large file I see a range between 16-24MB/s throughout the transfer. Only the faster 32GB card was able to maintain above 40MB/s write speed for the duration. There was also a big difference in 512K random write performance between cards (~1MB/s vs 20-24MB/s).

Write speed of 15-20MB/s seems to be typical of Ultra cards. They are good for general photography, but not fast enough for extended continuous shooting. Once you hit the buffer limit in the camera it can become very sluggish if the write speed is not high enough. If you only take one shot at a time the write speed speed should be sufficient.

I am tempted to remove a star because of the variance between cards, but all cards exceeded their speed ratings. The improved READ speed over the previous version is a benefit. Actual write speed may not be much better than the older cards. You might get an extra fast sample, but do not buy this card expecting outstanding write performance!

5Do you know what you're looking for in an SD card?
By E.
Absolutely a great buy. For the money I am very satisfied with my purchase. I think I may share something that a lot of people may not be aware of, since I have informed many family and friends and they said they we unaware and glad I had told them. When shopping for this type of memory card, there are a couple of things on the card to look for. The obvious one being the size of the card, this one being 32gb for instance. It's also extremely useful to know that the very small number with a circle around it is of importance too. This one has a 10 with a circle around it. These cards will have 1-10 on it. The significance is Minimum Serial Data Writing Speed,meaning Class 10 cards have a minimum transfer rate of 10 MB/s. Your card may also display a U with either a I or II in it, signifying the ultra high speed bus (UHS). Now apply this to what you're using this particular card for. I bought it for my trail camera. A class 10 card is used for full HD (1080p) video recording and consecutive recording of HD stills. UHS Class 1 cards are used for real-time broadcasts and recording large HD video files. Other cards would have worked for my trail cam but this one was ideal, and affordable.

5SanDisk Reliablity And Decent Performance
By EmbeddedFlyer
SanDisk cards, unless they're fake clones, nearly always perform near the top of their class. And, despite having used a few dozen of them over the years, some of which have been filled/downloaded/erased 100+ times, I've never had a single failure or corrupted file. And that's in sharp contrast to having had many failures from lesser cards that have had much less use. During a vacation in Bryce Canyon, for example, I filled my SanDisk card while out for the day and switched to a backup Transcend card. Everything seemed fine taking pictures and videos with the Transcend until back at the hotel room it turned out to be unreadable in my laptop. Even trying various "recovery" programs yielded nothing usable. It had failed and took a bunch of vacation pics and video with it. So, lesson learned, don't try to save money on SD cards unless it's for a non-critical application where you don't care if you lose whatever's on it.

That said, the SanDisk Ultra cards are a significant step below the SanDisk Extreme Pro cards in terms of write performance. The published specs are misleading implying the 80 MB/s Ultra is nearly as fast as the 95 MB/s Pro. But the write speeds to the Pro are typically at least twice as fast. If your application is mainly reading the card the Ultra is a good value. If you plan to write large amounts of data and don't want to wait, or shoot high frame-rate raw stills, or high bit rate HD or 4K video, get the Extreme Pro if you can afford it.
