SanDisk Extreme 64GB MicroSDXC UHS-1 Flash Memory Card Speed Up To 45MB/s With Adapter- SDSDQXL-064G-G46A [Old Version]

Muy buena compra

Works as it should, be careful fo the myriad of fakes out there and be careful to make sure you can actually use the extra speed in your device, lots of people buy cards that that they get no real extra advantage from. Sure its wonderful to show big numbers. We all know mow is always more.However what a card will do in a USB 3.0 reader attached to a PC is not the same as your smart phone that does not need 60MPS write speeds.I purchased this to use with a prototype tablet with a snapdragon 810 Octocore processor and a camera that is (XXXXXX) that records in H264 at 210 Megabits, The card can just about do this for a long time. No consumer product will need this and as we move to H265 it will become again a little less relevant. \So my 2 cents, make sure you can use UHC 1 or above and not just class 10. Understand and learn what the markings mean. Make sure you get a card that works with your device and not the most expensive card.

This microSD card is not the cream of the crop (Extreme Plus is), but it's still great.CrystalDisk Mark 3.03 x64 benchmarked with Kingston MobileLite G3 FCR MLG3 card USB 3.0 reader:43.65 MB/s reads38.91 MB/s writesRead speeds may look low, but write speeds make up for that, along with 4K speeds (not shown). Other microSD cards may advertise higher read capabilities, but sometimes it is only when it is plugged into a computer's USB 3.0 port, with actual performance in the device's microSD card being quite poor.Buying local? The price easily doubles that of Amazon.com's, at least at local Malaysian retail stores.I was actually looking for a Samsung microSD card but I was not sure of their international warranty policy. I even called them up to ask, and it seems that warranty only applies to the region where you bought it.SanDisk's superb lifetime international warranty clearly outshines that. And with its waterproof and resilient capabilities, this microSD is built to last.

Have been using it for a couple of weeks now with my GoPro Black Hero 3+ and have not had any issues. Work as intended.Revised Jun 27,2014:I noticed that the card was having problems recording anything above 1080p60. I tried recording at 1440p48 or 4Kp15 to get that extra slow motion playback, but the video was stuttering ever three or four seconds. Some of my clips didn't even record the audio. I have the latest GoPro software, I formatted the card inside the GoPro as well, but still experiencing difficulties. I swapped cards with my friend (don't remember which one he had - Delkin?) and the problem followed my card.This microSD card still works well at 1080p30 which is fine for my setup at home or for anything I post online. Down the line when ultraHD becomes the norm, it will be time to invest in a professional grade microSD card.

I bought this microSD card to use in my Lumia 1520 to expand the memory. I did not know until after I bought it that only media files can be stored and transferred to it and I could not use to to expand the hard drive for my apps. In the long run, the product did not solve my dwindling memory problem as all my apps are still on the phone and only my pictures and videos are on the card. Still a good product though

The biggest bang for a buck!It is fast and reliable.I tried to put a lesser quality card into my Note 3 and lost a number of pictures right away.Besides, that card was slowing me down significantly.This baby is FAST. With a OEM card reader I clocked over 35 mb/sec writing speeds (on USB3).I tried to write to the internal phone memory and to this card and did not notice any speed difference.If you have a latest smart phone, do not slow it down with a cheap SD card and do not risk losing your precious data either.This card is a TAKE-NO-PRISONERS buy, not a compromise

Bought this for an action sports camera and it works great. Let's me shoot video for hours and does the job perfectly. I wish I had more battery life to allow me to record till this card was full. I can't tell you how many times I missed that elusive shot of Sasquatch while biking a moutiain trail or the Loch Ness Monster while surfing due to a dead battery, but I know I have a memory card that is up to the task. I recommend this to any action sport enthusiast or mythical creature hunter!

works with my phone and does well with read/write speeds on my Note 3, I haven't had a 64GB version go bad on me yet and I also use it GoPro for recording as well as my various tablets.

I purchased the extreme micro Secure Digital eXtended Capacity memory card to film up to 4K videos and for burst shooting. 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 Speed Class 2 translates to write speeds of 2MB per sec. This is the sustained writing speed as opposed to the maximum instantaneous write speed.You may come across UHS (Ultra High Speed) symbol and this also indicates the minimum sustained writing speed. UHS is the fastest performance available on the market today. Currently, there are two types of UHS classifications: UHS-I Cards, write speed of 10MB/s and UHS-II write speed of 30MB/s. It is worth mentioning that UHS Speed Class is designed for UHS devices only. Refer to the image below.I've used other brand UHS Speed Class-I 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.

After a month I got the issue of occasional file corruption.After another month the issue got worse and whole folders went missing. I did a reformat and the card worked again.Coming up to 3 months the card would refuse to hold more than about 7Gig before corrupting files. I tried it in various devices to confirm this.After 3 months the card couldn't be written to, but it would still read ok.I tried re-formatting and the recovery options in SanDisk rescue pro but that just confirmed the card could not be written to.Returned to Amazon for a refund. A real shame as I got this for £37 as part of a special offer and I can't currently get another for that price.

At the time of writing this review I bought this memory card for a work related phone. They work fine in the Samsung Galaxy S5 mini phones. We are happy with the read and write speeds. Best to purchase directly from Amazon because you assured to get a genuine product, and in the rare instance that there may be a problem, Amazon is easy to work with unlike some third party sellers . When installed you will not get the full 64Gb from the SD card - but that is to be expected, so please bear this mind.

I bought this for use in my GoPro Hero 3+ Black Edition camera & even after several commerial shoots and falling off my bike at 45k while installed in the camera, the memory card records flawlessley with at all shooting speeds & frame rates, including for picture taking. It's pricy, but has proven to be robust & reliable.

Unfortunately this item didn't function correctly when I opened it (problems with formatting) and sadly I only found this out after opening it 40 days after purchase so returning it to the original retailer is not an option.Thankfully SanDisk have excellent customer service and have offered to replace the item free of charge (including postage and packing). Both very disappointing and pleasing at the same time!
