Product Reviews

An upgrade in READ speed, write speeds vary

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/s32GB (2) Read: 97.7 MB/s Write: 20.9 MB/s64GB Read: 82.4 MB/s Write: 19.1 MB/s128GB Read: 97.7 MB/s Write: 38.5 MB/sSanDisk Ultra 40MB/s (old version, 2014-2015)32GB Read: 47.8 MB/s Write: 19.9 MB/s64GB Read: 47.8 MB/s Write: 16.2 MB/sREAD 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!

Do you know what you’re looking for in an SD card?

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.

16GB stores 3749 photos on 16.4mp camera

16GBWorks great. Using it in a fujifilm xp120 16.4mp camera. The camera I have displays on screen that this card can store 3749 “normal” quality photos. If I change the settings to the “fine” (highest) photo quality it says it can hold 1188 photos. Not bad for under $10. Write speed allows me to take one photo a second just fine, which is pretty much as fast as this camera can take pics. My camera doesn’t have burst mode so I don’t have experience with taking photos that quickly. Would recommend.

Always trust SanDisk

I’ve never been let down by SanDisk! Always a trustworthy brand, & the only brand SD card I feel comfortable using.This card works great, nothing bad to report, as usual! Tons of memory space, will hold 100’s of photos.I’m using this in a Canon PowerShot Elf camera.

Great card for 1080P video recording

This card has been plenty fast for full 1080P video from my Cannon HR600R camera. I have used it constantly for making YouTube videos and it works great and have been 100% reliable.

BE CAREFUL - THE SPEED RATING DOES NOT REFER TO …

BE CAREFUL - THE SPEED RATING DOES NOT REFER TO WRITE SPEED. This is in fact a rather slow card. Sandisk are completely hiding the speed rating for this card, other than saying it’c class 10 (so roughly minimum 10mb/sec). For occasional use, i.e. amateur photography and normal HD Video this should suffice, but if you are a heavy user (continuos shooting, RAW shooting, 4K, etc.) - this will be too slow. Opt for the Extreme version - it’s only a few dollars more.

SanDisk is one of my two top choice brands for flash memory

SanDisk and Samsung are my standards for Flash Memory. I do not think you can go wrong with either brand. My advice is to compare them and go with the cheaper one - they are always fighting each other price wise so take advantage of that. Both are perfect and both get it done.

Great memory card for digital cameras.

I’ve had a Sony Nex-6 camera for some time. When it took a picture there was an extensive pause as it went to work storing the picture. It made the camera slow to use. I replaced the card in the camera with this card and there was a major improvement in the speed of the camera. While the buffering of rapid shots showed little improvement the write speed of individual shots improved tremendously. A very cheap fix for what was a major problem for me. For what this unit does and the massive amount of memory, it is almost free, especially for those of us who remember how incredibly expensive it once was to add memory to a computer.

Memory that is fast and plentiful

I wanted a large SDHC memory card for my digital photo frame. This was perfect. I was able to load many of my treasured vacation trips with music to accompany the photos.
