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!

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.

SanDisk cards have always been reliable. I use SanDisk SD, micro SD, CF, flash drives, etc… and they’ve never let me down! These Ultra cards aren’t necessarily the fastest thing on the market with an estimated 80mb/s, but they’re ridiculously practical and economically priced.

As a professional photographer, I like to back up my photos to multiple sources–generally, at the very least, on at least one external drive and one cloud storage drive, but lately I’ve been using these cheaper SD cards once and saving them to make sure the RAW photos are backed up in yet another source. That may prove to be too expensive over the course of time to use an SD card once and theoretically never again, but after having a Sony card fail recently after a shoot, I’ve started to shoot redundant to more than one card and I’ve started saving the cards instead of re-using. Only time will tell if that will be worth it to continue to do it that way, but like I said, these cards are so inexpensive that it just seems to work right now…

I have been buying SanDisk brand of memory cards for years and has been of great price value and make. I also buy Kingston brand for which ever can be of lower price. SanDisk however has a more aggressive selection and reasonably priced. What else can I say about a memory card? It works…ok maybe adding the fact that when you want a decent quality SD card, make sure you have a good rating to support both taking pictures and video recording.

Shame on me for not being familiar with the memory card my wife’s camera uses but shameful of Amazon to pair this card with “frequently bought together” with the battery I was ordering for the Canon 7D. This card is not for the 7D as the advertised “pairing” would lead an ignorant buyer to believe. Unfortunately for me and wanting to surprise my wife, I opened the card to install it into her camera. What a shock for me. While I am disappointed in not having done my homework, I am also disappointed with the way Amazon paired them. In a way it is deceptive. Why would people frequently purchase this SD card when purchasing batteries for a Canon 7D that uses compact flash?

SanDisk is built to last, well-made, reliable, fast and efficient. I use them for digital cameras, mini computer notepads and computer games for kids or any other electronic device which requires a memory chip.

This particular one: SanDisk 16GB 80MB Memory Card I used for a digital camera. The camera has memory storage but you need a large memory card so you can store a huge number of photos. What better memory card than SanDisk?!

I have been using SanDisk chips for ages and I am sold on them. I am a computer scientist and journalist. If they are good enough for me, then they are good enough for you! Go for it because it passed my perfectionist taste and tests.
