Side by Side Comparison of: SanDisk

these is the 5th time I have ordered these I just filled three of the 8gb with all the CD's containing music so I could retrieve some wall space in my home. could not believe I got close to 400 cd on these three. the sound quality is as good as the cd's I have found I could place a three drawer file cabinet full of scanned papers on one and now I am looking to get more to transfer all my DVD movies onto. Scan disk has been consistent in their quality so I turn to them repeatedly. I do not hesitate to recommend them.

I bought these cards to give to someone along with a an older Canon SX-10 IS camera I was no longer using. The recipient of the cards is happy with how they work and I have used these same cards in trail cameras with no troubles. Obviously, they are best used in cameras and devices that do not require high speed recording so if you are looking to use these on a more recent camera you should probably look at higher capacity Class 10 cards. If all you want to do is take photos they will work fine for you, and while I've used them for short videos, there are better choices for not much more money.

I have a canon camcorder that is a couple years old. It has an internal.memory and slots for 2ad cards. The color on the internal memory was never right. The sub slot would not work. I could do a work around with orca but the color was still bad. I ordered an Sd card. It came in a day I told my wife she was about to hear either sounds of complete joy or of the camera smashing against the wall. It worked! Recorded perfectly. Put it in a card reader to download,made a DVD,watched the dvd. The playback was perfect. Your sd card made me have the happiest day I ever had with a computer or camera.

These work fine. I had one go bad once and it turned out to be a bigger deal to exchange it than it was worth, so I just view them as expendable now and go on. Maybe they work for storage, but I just use them to transport images from cameras to hard drives. They seem more reliable than I imply with the sentences above. I suspect water does not compromise them, nor does heat or cold, as far as I can tell. 8 GB holds a lot of one megapixel images. Class 4 is fast enough for several of the items that I own that I use these in (for instance they are fast enough for images from a Primos Truth Cam 35 camera (a.k.a. one type of Trail Cam), which is a type of mounted, motion sensing, day and night camera that can be left out in the elements for weeks or more).

SanDisk is the best! I use SanDisk flash memory cards exclusively with all of my electronics that require them, e.g., trail cameras and other digital cameras. I have never had a SanDisk memory card fail to work and have used them where they were exposed to temperatures ranging from 1 degree (F) to 100 degrees (F) and in the rain and snow. I have several SanDisk memory cards and use them on a daily basis. As a matter of fact, I have four trail cameras operating right now that run 24 hours a day 365 days a year.

I purchased the 128GB version of this card hoping that it would work with my Panasonic 991 4k camcorder. I have gone through a few cards that advertised extreme speeds but when you look into them further they did not have sustained write speeds that could meet the demands of 4k recording. I am happy to report that this card really does work well for 4k video. It is class 10 and U3 which means it meets the minimum requirements for most consumer 4k recording devices. The price was also very reasonable and actually was less than the 64gb versions of other similar speed cards.*** Positive Points: ***- Able to record 4k video- Good Price- Lifetime warranty*** Negative Points: ***- None

Great capacity and performance. For my full frame DSLR, large RAW files write quick enough to avoid filling up the small in camera memory buffer when taking high speed sports photos. Got this at a great price on a lightning deal and came with promo code for free Shutterfly photobook.

As a full-time wedding and portrait photographer, SanDisk is the #1 trusted memory card manufacturer on the market. Okay...#1 is completely my opinion but I have used nothing but SanDisk. I have had ZERO corruptions/failures and even accidentally washed one in the laundry while vacationing!!! And if you're asking why so many cards, I shoot with two Nikon D800's and their files sizes are ridiculously AWESOME!!! Haha

I recently got really interested in photography and video. I purchased the Lumix G7 mirrorless DSLR camera. I needed an SDHC card that would allow me to shoot 4k and take fast burst photos.Do I need to spend another arm & leg to allow myself to record in the beauty which is 4k? NAY. Get this to solve your worries, child. Best bang for your buck.So. While reading reviews for Micro SD cards on Amazon, I was surprised by how many "fake" cards were reported. Apparently it's a big deal and has made it's way even to Amazon. So be careful with that. I found no indication of this being fake, thankfully.Performance:Most important. Does it work without hiccup? When shooting 4k video (100mbps), I have no issues issues. Camera doesn't suddenly turn off like other less powerful cards might. It's also recognized. Other owners of the G7 have complained that non U3 cards weren't recognized. I got the U3 for piece of mind knowing that it would handle whatever I threw at it. It does!Value:For the price and performance, this is an excellent product and offers great value. For a class 10 U3 card, I think this was the best bang for your buck. I've had great experience with SanDisk in the past. They continue to offer products which work well. SD cards continue to fall in price. The price difference between the high end card like this and some other mid to low level card is minimal. Might as well get this even if you don't plan to shoot 4k.Summary:Overall, I'd highly recommend this card. If you ever plan on shooting 2k or 4k or high burst photos, you'll most likely need a card of these specs. Sure lower end cards might work, but they're not guaranteed to keep up. This is good for future proofing. Those higher formats are quickly becoming the norm. You don't want to be stuck with a card that can't shoot at those qualities. You'll end up having to buy this in the future, might as well get this now.I'm satisfied with my purchase and haven't had any issues. Provides me with the capacity and speeds to shoot at 4k. This is probably the best value card which can do that. The price difference to upgrade to this is minimal. Just go with this one!Hope this helps

At first I was excited to find such an inexpensive option that is capable of 90MB/s write speed. But then after reading the first part of the product description I discovered that these are only capable of up to 60MB/s write speed. Well, 60MB/s is still great at this price point so I ordered two!Well, the cards arrived today, so I decided to test one of them. I tested the card and found that it is writing at less than 50MB/s. So, I looked a little more carefully at the product information and see that only the 128GB and 256GB versions of the card operate at up to 60MB/s; the smaller cards are 40MB/s. It's very frustrating to have cards advertised as 90MB/s, and then find out in the fine print that the write speed (the most important speed for taking lots of photos with a high megapixel DSLR in RAW) is half that speed. So, minus one star for irritating advertising.Edit: The listing has changed to clearly indicate the write speed now, so I'm giving the star back. :)

Good Flash mem

THEY WORK WELL

I have several camera's these disc's will work in all of them..

They work OK , but, I would buy a faster card like a (10) SDHC flash memory card. You can just about see the rating marked on the card.
I did not know how they were rated at the time I bought them , but, the 8- (4)SDHC work fine. I would like to max out the speed of the camera with a faster memory card like the (10). Next Time America.

I use a lot of SD cards in game cameras left "in the field" to document wildlife movements. The San Disk brand are as good as any, and normally more economical, so I tend to use a lot of them. This was a good price on a good product.

I'm so glad I get these for my Canon PowerShot. They're waterproof, shatterproof, drop-proof, weatherproof. I'm also so glad these are on the market. I hope that when something actually happens, they'll pull through and do what they're made for: to survive.

I bought this for music in my car. I've noticed some songs don't work anymore after the disk was exposed to high temperatures in the summer. I haven't tired to reload the songs from a computer though

My wife is a YouTube vlogger and content creator. She always complains how long it takes to transfer her videos from the SD cards to her Mac. I looked at her SD cards and saw she had been buying 40 MB/s cards.I gave her a quick explanation of data transfer speeds and her eyes glazed over. So I just bought this card for her instead. The cards work great, but my wife hasn't noticed any improvement in the length of time it takes to transfer video to her computer. I haven't benchmarked it to be sure, but I would expect at least a somewhat noticeable difference when going from a 40 MB/s card to a 90 MB/s card, especially on a high end Mac.If you're looking for a reliable card at a fair price from a reliable brand, this card is great. If you really need bleeding fast speed of go with one of the Pro versions, even if they are a bit more.

This is a lot of memory for a great price by a company I trust. All very good things. There are limitations on how I can use that memory that I did not anticipate.My laptop has 100 Gig hard drive that is 63% filled with programs. I was down to 6 Gig of unused space....very tight indeed. So my thought was to move my data to this very large SD card and access it there instead of drive C. Well, it won't back up from there and files don't want to save there. So, I moved a modest amount of my data back to drive C and use the SD card to back up this data. The rest of my data files are not needed on a frequent basis so I left them on the SD card. My Cloud backup will only back up hard drives. So it will NOT back up the SD card. I do have this same relatively inactive data on another 128 Gig memory stick.

The card is as advertised, however please read carefully before buying. The write speed is 40 MB/s and only read speed is 90 MB /s unfortunately this was not displayed as vividly as the write speed and I fell for this. Buy the pro version as now the difference in price is also just a couple of $. Its a good product but they should not take advantage of such labelling.

Intro note: You probably don't need this card if you're just an amateur/casual photographer or if you need it for a handheld device, such as a Nintendo 3DS. I would just get something cheaper.I don't usually write reviews because I get too lazy, but because this is a new card and there aren't any reviews, I thought I'd pitch in. Some background info about me--I'm an intermediate photographer/videographer that mainly shoots 1080p/24fps and 1080p/60fps video using a Canon 70D, so I can't give real life feedback on 4k shooting(sorry), but I will include average scores(that include 4K) from the Crystal Disk benchmarks that I've ran.DSLR usage- The card writes very fast so that pictures practically show up immediately after being taken on the LCD screen. Also, browsing quickly through the gallery of photos cause nearly no delay for the picture to show up.- The card can keep up amazingly with continuous shooting. As you may now, the Canon 70D has a pretty good continuous shooting rate that doesn't slow down unless you're shooting in raw. However, most of my sd cards will down after the ~40th shot or so, and the camera is forced to take pictures at a slower rate until the card "refreshes" and is back up to speed. Not the case with this card. It held up beautifully and the camera hit its buffer when it was supposed and not any sooner. This is good news for action/wildlife/sports photographers.Computer usage- I recommend you take a close look at the benchmark scores below. Read/write speeds are true to Sandisk's claims of 90 and 40 Mbps respectively, however, it is sometimes a little lower or higher. Transferring 20 gigabytes of photos/videos is a breeze, but obviously it won't be twenty seconds--let's be real with our expectations here, this isn't an SSD. Unfortunately, like other cards, it runs at advertised speed for about twenty seconds, and then it dips to half of that for three or four seconds, and then it's back to 90 mbps. The same is true for writing speeds. I believe this is due to the card hitting its buffer zone, similar to what a camera on continuous shooting mode would do. If I am mistaken on that, please correct me.-The benchmark rated the read/write a few mbps higher than what Sandisk claims, but I find that it's usually smack dab on 90/40.Overall, I really recommend this card for the intermediate camera users and above, although I'm sure a serious professional would use something better, especially those that are doing serious video editing and need a speedy read/write from their SD cards. Again, if you're just starting out in photography, this card is unnecessary, but if you can afford it then why not.**Benchmarks:-----------------------------------------------------------------------CrystalDiskMark 5.0.2 x64 (C) 2007-2015 hiyohiyo Crystal Dew World : http://crystalmark.info/-----------------------------------------------------------------------* MB/s = 1,000,000 bytes/s [SATA/600 = 600,000,000 bytes/s]* KB = 1000 bytes, KiB = 1024 bytes Sequential Read (Q= 32,T= 1) : 93.330 MB/s Sequential Write (Q= 32,T= 1) : 49.148 MB/s Random Read 4KiB (Q= 32,T= 1) : 9.934 MB/s [ 2425.3 IOPS] Random Write 4KiB (Q= 32,T= 1) : 4.057 MB/s [ 990.5 IOPS] Sequential Read (T= 1) : 95.617 MB/s Sequential Write (T= 1) : 48.860 MB/s Random Read 4KiB (Q= 1,T= 1) : 9.425 MB/s [ 2301.0 IOPS] Random Write 4KiB (Q= 1,T= 1) : 4.097 MB/s [ 1000.2 IOPS] Test : 1024 MiB [F: 0.0% (0.0/29.7 GiB)] (x5) [Interval=5 sec] Date : 2015/09/10 17:34:01 OS : Windows 10 Professional [10.0 Build 10240] (x64)

Becoming obsolete by Apple and Samsung products

The only complaint I have about this product is that the Flash Memory cards did not come with a plastic storage case. Once you open the package their is nothing to put the memory cards into when they are not being used.

Grandsons needed these for school. Assume they do the job as they have not complained about them

These were advertised as 8 GB.I rec'd two 4GB cards. That's okay, I can use same.

I think these will work fine, I just got the wrong ones. I needed the mini's. I will find a use though.

went bad two weeks after I had it .It literally fell into / Sepertated

We have these chips in all our chip equipment. Holds eveeything we want to do .. Video, pics, docs. Great storage/archive and retrieval is just as easy.

Lock slider is terrible. Takes me 10-15 tries to get the card into my camera without the lock sliding down. Eventually I just taped it in place. Stupid feature that has been around way too long. At least strengthen it!

These are all right for most things, but they do not do well in a D610 on continuous mode. I've missed some images because these cards couldn't keep up with the buffer on the camera. Also, one of these cards failed after only a few months of use; I expected better from sandisk.

Wrong size/format was ordered, make sure its the right one you need as we discovered we could not return for refund so stuck with these items.

I have always bought SanDisk SD cards. I now have four of them. I have an older version of this model- the Extreme 32GB 45MB/s. That has a capacity of 29.7GB, which makes sense because manufacturers define a gigabyte, or GB, as 1 billion bytes, which computers define a gigibyte, or GiB, as 1,024,000,000 bytes. However, when I received this card in the mail, the capacity showed 28.7GB. How could the capacity between the old card and the new card be a whole Gib?!I called SanDisk and basically got what I just described to you, the difference between the definitions of capacity, but nobody really answered my question about the difference of 1 GiB. I called back to get someone else, and eventually connected with a "Level 2 Technician." He explained it a little more clearly, and it seems the technology and firmware for achieving UHS-3 speeds (the older card I have is UHS-1) takes up more space. I don't know if that's a load of bull, but I found another review on Amazon for a SanDisk 32GB microSD Extreme card mentioning the same issue. This is really unfortunate. I know it's only a GiB, but that's good for a few hundred pictures.SanDisk offered to replace the card, but the tech said the capacity would be the same. Whatever. I've spent a long time digging to find if this is a problem with other cards, and I found one or two examples. It might just be something to do with the increased UHS-3 speeds.All in all, SanDisk makes great SD cards, but this experience left me thinking if I'll buy from them again. But what do they care? They're a corporate giant that won't notice if they lose a few customers.

The memory card stopped working while I was taking wedding pictures, I was unable to get any of the pictures off the card after it stopped working. I luckily had extra memory cards on me. If you're a photographer, do yourself a favor and invest in good memory cards, these are unreliable.

Always make sure to double check s/h prices first. 11.00 to ship a lightweight 8.00 package is rridiculou.

Disappointed they didn't come in the protective plastic cases like most sd cards come in.

they did not work in my game camera, do not know if they are to large (8) and I need a smaller, will check with the camera specs

Apparently these are micro-sd cards. Would be nice if it said so or was pictured as such.

still waiting for better speeds. Lags while recording and creates gaps.

I've had two of these die on me in six months.

I had a problem using this SD card on my computer. When inserted to my laptop, I can not view any of my images, it would also make a glitchy sound when being inserted. Also my other option was connecting it from my camera to my computer, when viewing the file of pics from my camera folder they were visible, but it still did not allow me to see my pictures as a bigger image. this is very inconvenient and I would like a replacement, never had such a problem just looking at pictures I've taken on my computer. Please send me a working SD card.

Lost data! Sucks, I had some nice videos on there too. Well, it could have been because of the adapter (https://www.amazon.com/Adapter-standard-Connector-Smartphones-Function/dp/B01BXSKPES/ref=sr_1_1?s=electronics&ie=UTF8&qid=1466599558&sr=1-1&keywords=Micro+USB+OTG+to+USB+2.0+Adapter%3B+SD%2FMicro+SD+Card+Reader+with+standard+USB+Male+%26+Micro+USB+Male+Connector+for+Smartphones%2FTablets+with+OTG+Function) - this one. But either way I lost some video which I wanted and that sucks.Was working fine last night. Woke up this morning, put it in the adapter and into the USB and it didn't read it at all. Restarted my computer and it read the card, but then all my videos were erased! So I put the card into my camera to see if it would work and it didn't. The pictures and videos were gone and the camera wasn't recording to the card. With the card in the camera it just stopped recording. The record function would turn on but it wouldn't actually write. The timer just stayed at zero. So I believe there's either a problem with the card itself or the adapter. I am writing negative reviews for both. Hopefully they'll let me get a replacement for free. Sucks.**UPDATE** Contacted sandisk and they won't replace the card. They even wanted me to pay for a recover system to recover my files. Am going to switch to Transcend because of the terrible runaround Sandisk gave me. Bad customer service.**UPDATE 2** Sandisk finally complied and told me to contact Amazon, they sent me a replacement out the next day which was nice.

I was very excited that the card at a reasonable price. I put it into my camera, Cannon SD 870IS. It did not work. It has a 'memory card error' message. I do not know if it is the defected card or it is not compatible with my camera. I returned to Amazon and got full refund. I love Amazon. I do not have to worry about if it did not work.I think the little 3 inside the U may represent something. I bought one without it. It works.

Receive error msg on this disc on both my cameras. First time that's happened. Maybe mine is defective. as this is usually great quality.

One is working as advertised; one worked once and then quit. Would not buy again.

one of the cards is defective. have it in a camera and it does not record a picture. tried it in other device and it still does not work.
not worth sending back for one card. I don't know if the other card is bad. I don't have the packaging any longer so will put in the trash.

Disappointed in the quality of the last batch I received. We have used SanDisk in the past. The tab to lock the card has broken off, which prevents us from using the card in our camcorder. Thus has happened with 6 of the 8 cards we bought. We tried taping over the area, but the card is too thick to fit in the camera.

One of the memory cards was damaged right out of the package. One of the gold pieces on the back was bent outwards. Cannot use.

Product was not as described in the ad. The advertisement said that it could be used in cell phones this why i made this purchase. This was incorrect. It doesn't fit. I had to make another purchase for the right size. I didn't bother to send this product back for a refund because it was too much of a hassle.

I am not sure whether I got a dud or whether this was just incompatible with my Nikon DSLR (model D5200). I tried using it a few times and the photo would take and show me a preview, but when I tried to review the photo subsequently it would say the file could not be read. I gave up on using it and considered it a waste of money until today when I tried once again and now it says the card is damaged. The card and files also do not appear when I connect my camera to a computer. All in all, a major bummer and I still need a new SD card ugh.

not sure if this a knock-off, storage of pictures on camera failed to unload all and some pictures were corrupted.

Failed after two months :(It failed just after two months of use, with a VERY IMPORTANT video of one of our interviews. Avoid it at all cost.

WATCH OUT for this one!!!! This card corrupted the second time I used it. Unfortunately it was a wedding ! ! ! ! ! !So ticked off about this San Disk!! ! ! ! ! !I have used San Disk cards for years and years and now this is also the second card that has corrupted in 2 months! Brand new cards!!!

Used it for the first time after having it for a month. Card could not be read. Data was unretreivable. I was outside of my 30 day return window. If you choose to buy this card test it immediately.

Very disappointed that there were corrupt files the very first time I ever used it. A complete nightmare! The picture preview on the back of my lcd showed pink people and sure enough when transferred onto my MacBook there were corrupt unreadable files!
