SanDisk Extreme 32GB UHS-I/U3 Micro SDHC Memory Card Up To 60MB/s Read With Adapte-SDSDQXN-032G-G46A [Older Version]

When I got my GoPro Hero4, I knew I had to get the best microSD card there was! I was looking to film and take photos. The capacity and speed of this memory card served it's purpose and I'm glad I went with the 64GB. If you want fast extra storage for you Android devices such as the Note 4, HTC One M9, or even tablets, this is the fastest you can get for a great price! My speed test was 59.79 Read and 40.02 Write! Excellent quality and I've owned this product for over 1 year. The read/write speed is still the same! Will work w/ 99% of Android devices, tablets, Microsoft Surface products, and all GoPro Hero products!Now to compare the competitor field:In testing, the SanDisk Extreme performed on par for what was quoted, In the random large-block workload, the Extreme Series 64GB had a slight drop-off, but it still retained its top-in-class performance. Additionally, we compared these figures to the performance of its higher-tier sibling, the Extreme Pro microSDXC, SanDisk's other top-of-the-line microSD card, as well as the Samsung microSDHC Plus and the lower-class Toshiba microSD card. Unsurprisingly, the Extreme Plus Series out-performed its competition, though cards like Samsung is nearly $20 cheaper at roughly $40 for the 64GB model. That extra $20 dollars goes towards a significant boost in performance, however, so it is up to the consumer to decide whether or not they need these considerable gains for their high-end smartphones, cameras, or tablets. With its performance, reliability, and SanDisk's trademark life-time warranty, I think the Extreme is a worthwhile purchase for enthusiasts. This product is B-23 approved!

I was looking for the best card I can get for my mobile phone and reached the conclusion that is this one, I've been using it for over a month and it lives up to its expectations. If you're looking for a card yourself I wrote my findings below to help you choose.There are many classes of cards. The newest are uhs-I and uhs-II. The latter is faster but only if your device is compatible with it, otherwise it won't play nice with your device. If you have a fairly new device and you're not sure which one you need, it's most likely a uhs-I device, as uhs-II is reserved only for applications where that extra speed is absolutely necessary.So you've determined your device is uhs-I compatible, Which card to choose?Well, there's a rating system, and the card will either be rated U1 or U3, this rating determines the minimum write speed of your memory card. U1 meaning it's rated for 10MB/s and U3 is 30MB/s.What this means is that if you're using a consumer electronic device, then the fastest guaranteed speed you will get from a card is from one rated as uhs-I/U3, like this one.This card also says that it has a maximum write speed of 40MB/s and read speed of 60MB/s, but the maximum values are not always attainable and there are many variables. That's why I chose this card over others that promised faster performance, as there is no guarantee you will be getting that kind of performance from them.

Works perfectly

I want to begin using my expensive cell phone for videos sometimes.I began thinking how much we pay for this amazing technology (our phones), and only use 10% of its abilities.I have 2 grandsons who are growing up too fast, and I thought, "how about when it is grandpas time to be called to the next life, what a wonderful gift I can give/leave them, but videos of some of my life."Events. Christmas with me. Holidays. Some of me at my job (they'll be curious anyway), and they can show them to their children.Me just working on my car, or fishing with them or my friends... Anything.And I wanted an sd card that will not lag (jumpy, pixelled, etc), with the video function of my phone.And this card does this perfectly.I now have video access with me any time I want, and allowed my phone to use its video abilities as much as it can.Not a thousand dollar camcorder. Its a phone. But I'll get a lot of spur of the moment videos for them, but its with me at all times.They'll have hours and hours of videos to enjoy, and instead of trying to tell their children down the road about grandpa, they can let my videos show them grandpa.

This product was good for its time, but now with the release of the newer version (ASIN: B013CP5IWO), its a no-brainer to purchase that rather than this. The image show the comparison benchmark between the Older Sandisk Extreme 32 GB (the product being reviewed), and the newer Sandisk Extreme 64 GB (ASIN: B013CP5IWO).*** TEST OUTCOME : The newer version does approximately 20% faster reads and 35% faster writes sequentially, compared to the older one ****Test Environment.—————————As you can see, the tests have been done using the latest CrystalDiskMark v5.0.2 64bit software. These tests consist of three passes, each of which in-turn comprises of 9 test runs - all of this just to make sure that the benchmark results are not just a “one-off” thing.All tests were ran on a Quad-Core / 16 GB RAM Windows 7 HP laptop with no background programs running, using the respective OEM SD Card readers from Sandisk.Explanation of the Test Types.———————————————Seq Q32T1: Sequential (Block Size=128KiB) Read/Write with multi Queues & Threads4K Q32T1: Random 4KiB Read/Write with multi Queues & ThreadsSeq: Sequential (Block Size=1MiB) Read/Write with single Thread4K: Random 4KiB Read Write with single Queue & Thread

I purchased the extreme micro Secure Digital High Capacity memory card to film up to 4K videos and to capture burst shooting in still cameras. In burst mode several photographs are captured in quick succession and this is where the speed of the memory card comes into play.Some background info that you may find helpful. For any given memory device, there are two speed specifications that are provided by the manufacturer and these are namely, the read and write speed. The faster the read speed the more rapid is the rate of data transfer to your computer. The higher the write speed the faster the images are saved onto the memory card. A Class 2 speed translates to write speeds of 2MB per sec. This is the sustained writing speed as opposed to the maximum instantaneous write speed. So the number shown on the memory card is the sustained write speed. Therefore a class 10 card will achieve 10MB/sec.I've used other branded 'high speed' (class 10) cards in the past and I found that during the shooting process, on occasions you can experience dropout or jitter. I have not experienced any such problems with the Sandisk extreme cards.There are plenty of cards out there that will do the job if you are just shooting standard photos or even capturing standard or HD quality videos. It is worth noting that image quality is unaffected by the type of memory card used. However using a low speed (say class 2) will process the information more slowly. It may also be less reliable and may corrupt you data more readily when used in high demanding applications.I purchased this item at full price. If the product is unworthy of a good review, I think it is unfair to leave positive feedback as this can mislead potential buyers. I hope you found the review helpful.

I tested this memory card on several systems and the best result was 47.2 MB/s read & 28.5 MB/s write (in IEC binary units) and that was using an 'ImageMate All-in-One SDDR-289' which is one of SanDisk's own USB 3.0 external memory card readers with no other devices connected to the host controller so there was as much bandwidth available as possible.These results are some way off the illusive "up to" figures stated by SanDisk which are 60 MB/s read & 40 MB/s write which I presume are specified as 'Millions' of Bytes instead of megabytes so for comparison's sake, that best test result of mine given in 'Millions' of Bytes per second is 49.5 MB/s read & 29.9 MB/s write (rounded-up in favour of the manufacturer ;-) which is only about 82% of the read & 75% of the write "up to" speeds stated.I had to source a USB 3.0 card reader especially for this in order to carry out a fair test so maybe specific requirements should be spelt-out in product descriptions on websites and packaging in future! (not just if's, but's, maybe's & "up to's")Buck-up your ideas SanDisk !!!

Tested this card on USB3 card reader (plugged to the USB3 port) and in my Experia Z3: although it never quite reached the maximum promised speeds, it's a pretty fast card for the money. The read speed averages at 45Mb/s and write speed around 34 Mb/s, it also seems to be reliable with no read errors. In my opinion is well worth the extra £5 compared to the similar baseline (slower) product.

Im a big fan of sandisk cards and use them almost exclusively (Although Lexar cards are proving to be very good value for money lately, and slightly less expensive), but these 16GB cards have been pretty unreliable for me. About 50% of the ones I have purchased have failed at some point whilst being used in my gopro.

Works with my gopro hero 4 black. Be aware that gopro cameras format cards over 32GB using exFAT (completely pointless as gopro segments files into 4GB chunks anyway) . This means none of the files created on the card will retain the original date and time created info. I would recommend formatting the card as FAT32 so that your original time and date stamps will be retained on the files, then never format the card in the camera.
