SanDisk Ultra 16GB Class 10 SDHC UHS-I Memory Card up to 80MB/s (SDSDUNC-016G-GN6IN)

This card was purchased to be used for professional photography shoots, and it has worked perfectly. I've yet to have any trouble with the SanDisk brand, at any time. This card is a Class 10, which means that it is capable of capturing information rapidly, so it is useful for serious photographers and for recording video. Those who require a class 10 already know so, and the rest of this review is intended for those who do not know so, and may find it confusing to navigate the Class number, vs, MB or GB vs. MB/s. I work with many older adults who do not want to be left out of using helpful devices, yet appreciate a little bit more information to help them shop for an item like this one. So, if you are unsure of what you need then this is for you! Usually, if you take casual photographs then you do not need to purchase a Class 10. You can save money by getting a smaller class number, without noticing any difference in your photographs at all. Another way that you can save money is to use cards with smaller capacity (fewer GBs). If you strongly prefer trying to get all of your photographs onto one disk, then the 32 GB will probably allow you to do that, if you have been saving the photos in a format like .jpg. If you have been storing as .bmp ("bit-maps") then each photograph is a very large file, and that is OK, it just means that it probably isn't realistic to have them all on one SD card. The number of them that you would need will vary greatly depending on how many photos you take and save. In that event, get one card and see how many you can store. From that you will be able to estimate how many more cards you will need. Usually, it's best to purchase cards with a LOWER storage capacity. This suggestion is in case one of the cards is lost, so that you do not lose as many files or photographs along with it as you would if you had stored more on a large capacity card. It could be the difference between losing one photo album or your lifetime of photographs. These cards can also be used to store files on them. If you remember being told that there would be a paper-less office (which still hasn't happened), using these cards could allow you to achieve that at home, if you wish. A little thought will show that there is wisdom in keeping separate cards for your emergency information, recipies, estate planning, etc. They are also inexpensive enough and small enough to put copies into your safety deposit box. One of the additional benefits of the SD brand is that they have, however small, a place for you to label your disk right on the front. That little area is essential in my opinion because without a label, finding the disk that you need could take hours or days of inserting card after card to read the contents. I do not purchase SD cards from companies that have no way of labeling them. It is not a good idea to put your own label on these cards- please do not do that. Sometimes these cards fit tightly into slots on cameras, tablets, laptops, PCs and printers. Your additional label will only stick for a while, and because it adds thickness to the disk, on some devices it may be getting scraped off as you insert and remove the disk. The risk to you is that you'll have a label stuck inside the little SD slot, and might not be able to regain use of it. I won't take that risk. If you have been using USB drives to save information, then switching to SD cards like this one could save both space and money. I will need to start doing that, myself. Two years ago I purchased a USB organizer with 8 pockets in it, and I have kept my information for different activities all separate. Unfortunately, as different projects came up, I found that the 8 pockets were inadequate, even though there is plenty of room on the separate USB devices. I had 2 more floating USB drives inside the case, and then more USBs without a storage "home" getting misplaced. So, have decided to stop purchasing USB drives to store data. These SD cards are much less expensive, smaller and easier to store. There are "USB, SD card readers" that accept these disks and allow you to use the USB drive to access, add or remove information, so it does not leave you dependent on finding a computer that has an SD slot. It helps to keep the data more organized, more secure, and to be able to share items when I wish to without privacy issues. When you are purchasing electronic items such as mobile phones, audio recorders, electronic picture frames, and other items, always check to see what forms of storage are accepted. Any device that cannot accept some form of storage will quickly become overloaded, and all of the jaw-dropping applicationss are quite useless when there is no room left on the device. For example, there are mobile phones that do not accept storage cards. They also do not have much memory, so you can end up stuck having to figure out how to get previous videos of grandchildren, or pictures of the new puppy out of your phone. Usually you would have to pay for a data plan, and figure out how to upload to a "cloud," which will also require an account and password, and most likely limit your capacity unless you purchase more space. See how frustrating a phone like that is? Again, before you purchase an electronic device, find out what storage it will accept. If it doesn't take a storage card, then re-evaluate whether that is the device that will work for you over the long term. If the device happily does take storage in the form of a "micro-SD," then instead of getting a smaller capacity, I recommend getting one with as much storage as you can (more GB= gigabytes, the way the storage is measured). This is because "micro-SD" cards really are small! They can be difficult to put into and remove from devices, and hard to manipulate, too. Having the larges storage capacity that the device can work with will save you the hassle of removing such a tiny card to transfer the information (there are adaptors the size of the SD card pictured here that allow you to move the information off of your mini-SD card onto your PC or tablet. If you are simply getting a different mobile phone, then having one with a mini-SD card will allow you to transfer over all of your contact information. Sometimes people worry that they will lose such a small card. Most of the time it will be in your device; it is helpful to know that there are storage cases to fit your micro-SD card along with an full SD-sized adaptor, all in one place. They are usually clear and can be labeled with a Sharpie. You can find some that only hold MBs, 4 or 8 GB. If you are using an older device, a smaller storage size like that may be necessary as the newer cards might not be compatible. Check the owner's manual to find out what SD cards are compatible. For those who haven't used these before, it's possible to find yourself pitted against a device with half a dozen different sized slots. You absolutely cannot use trial and error to see which slot will work- putting the wrong storage device into a slot is one of the few things that you can do to break the reader and have the device no longer able to accept and read the storage card that was meant for that slot. So, I am including a photograph of what an SD card slot may look like. This one is on a laptop, and is a little larger than most because it accepts 3 different kinds of storage cards. There is extremely small print engraved into the laptop to indicate which cards may be used with it, and this type of frustrating, difficult-to-read labeling is now very common on devices. Although it is nearly impossible to read, please do not resort to techniques like using powder, toothpaste or such to highlight the lettering, because it is too easy for things like that to get inside the card slot and ruin it. Instead, try using a bright, preferably LED flashlight at different angles, a magnifying device, or an eagle-eye helper. Please notice on the photograph that there is a square outline, and you can hardly see that the top right corner appears clipped off; this is just above the first letter "M." It looks like it could be a curve or just might have been left off due to the placement of the opening. Actually, that little cut-off-corner angle is meant to match the SD card pictured here and it is so important you'd think that it would be marked with large, red warnings! All SD cards have that little clip off of the corner, and it is used to help you make sure that you put the SD card into the reader with the correct orientation. Otherwise, you guessed it, you could damage the reader and/or your storage card. So, when you insert your SD card into a reader, be sure that the clipped corner is inserted the way the device has pictured it. There is one more thing on the SD card that may lead to confusion, and that is the MB/s. That speed tells you how quickly data can be saved and retrieved from the SD card. It will always be at least the same as the class level (in this case, 10). Will it make a difference from day-to-day? Well, if you are finding this review to be the right level for you and helpful to you, then probably not. If you start doing activities where it may matter, there are plenty of resources online and at your local electronics store.

I LOVED this, the storage is great! I have had it for maybe a half of year and it’s not even full yet! I would highly recommend!!

Works great in my camera!

Works as it should

The sd card came in good condition. The only thing is that when inserted to my camera, it says it has 59.4gb instead of 64gb. Which isn’t a HUGE deal, but again.. i paid for 64gb. Will still be using and testing it.

Works well

It’s a SD card nothing much it’s reliable.

great price fast shipping
