SanDisk Extreme 32 GB SDHC Class 10 UHS-1 Flash Memory Card 45MB/s SDSDX-032G-AFFP

I was initially impressed with the speed, it was exactly what I needed for my Canon T3i while all of my other SD cards were simply too slow to keep up with the Burst speeds and Video from my SLR.Within 3 months the plastic started cracking, the top corner broke off and I had to repair it in order to recover the files on the card (the top corner is responsible for telling the card reader that the card has been inserted). Over the next few months, the case began to split down the middle and it's having a lot of trouble being recognized by my cameras and card readers. Many of the card readers detect that the card is write-protected when it's not. The case is just disintegrating on me, and put up against about 3-4 other SD cards that I use often, it is the only one of the bunch that has shown so much wear.Sandisk doesn't seem to believe it is a counterfeit, but they are claiming that I abused it, because moving a card from a camera to a card reader and back counts as abuse......Oh well, just ordered a Samsung 80MB/s 64GB.

I bought this card as a replacement of my dead sandisk extreme. The old one (sandisk extreme 16 gb 45mb/s) was bought 5 years ago and it had been used heavily (almost on daily basis and occsionally under extreme weather conditions) until it suddenly died a few days ago.Although I was a bit upset since I lost some data with the dead SD card, I still wanted to stick on the same brand and model due to its great overall performance under challenging conditions. Basically, sandisk is among a handful of companies that are famous for the storage devices and that was the driving factor behind this purchase.It came in a frustration free package and the labeling was strikingly different from what is shown on the amazon product page. That picture looks like my old sandisk. This one came with a golden colored tag instead of this red-black classical tag. Another surprising part was the lack of sandisk imprint at the back. It only says' made in China' and a serial number and that does not help much at all..After a bit of google search I found out that many people receive fake (imitation) storage devices and Sandisk website does not posses a handy mechanism to distinguish the fake from the genuine one. The only recommendation is to buy it from an authorized vendor and a list is given for each country. Luckily, Amazon is among the authorized vendors and if you are buying the product directly from amazon (not a third party seller of the amazon market place) you are doing the best and the only thing you can for getting a genuine device.During my internet search, I found out a highly praised software called H2testw developed by Herald Bögeholz which tests the portable usb devices and memory cards bit by bit against bad sectors and other hardware issues. It also gives write/read speed information (that part you can do by transferring a file between your computer and the sd card and let windows measure the transmission speed for both directions).The software did not find any damaged sector in the device. The actual storage area for 32gb one is around 30430 mb and it writes with a speed of 38-38.5 mb/sec and reads with a speed of 39.5-40.5 mb/sec. These numbers matched exactly with my own test by transferring two video files. These performance ratings are slightly low compared to the product claim of 45 mb/sec but still pretty close.Finally, it comes with a 5 year warranty (what a coincidence my old one died exactly five years after the purchase) if you ever remember to file a warranty claim for such a stuff.As of July 2014, I purchased the 32gb 45mb/sec version directly from amazon for $25. If you can find the same product with a similar price, then it is worth the investment. If not, I would go for other brands like transcend and kingston, this will not live forever anyway

I learned which SD disk would be best for me by reading a Wikipedia article that explained the nature of SD data cards and the nomenclature that would identify the card(s) that met the minimum specifications for my new DSLR camera. The faster cards enable video recording and burst photography, something I always wanted to do. Several cards are "fast enough" and the prices per GB vary as expected.There is a website showing the results of actual field tests performed by a fellow who had a testing lab available and he took it upon himself to test the latest models, the "hot new cards."Interestingly, the new high tech cards did not perform any better for photographers than the earlier edition. They may be good for some applications, but not mine. The test results turned me back to purchase THIS card because it had the best performance at the lower price while the cost per gigabyte of storage capacity was lower.In the field last night, I caught a wonderful Alaskan sunset where the clouds were just right and the light was perfect. I shot hundreds of photos. My card has a huge inventory of sunset photos to choose from and the card has gobs of room left (that's a technical term) and I have ample storage capacity for more if I need it. This card is Ideal for a weekend trip or vacation.Perhaps this will lead you to conclude this is today's best card type for DSLR cameras. I bought three and there should be no need to replenish my inventory for quite a while.

I like these a lot, and they definitely beat out non UHS-1 cards by a lot in terms of speed. Sandisk has also been a very reliable brand for me in terms of data integrity.The read speed matters if you have a USB3.0 reader, it won't matter much if you don't.The write speed is determined by the class-1 destinction of UHS-1. This is the speed you need for 1080p video BUT, supposedly some Sony cameras prefer a 15MB/s minimum write speed. class-1 (This one) is only 10MB/s. I haven't tested but in my NEX-6 anyway this card works fine. In my NEX-5R, I have had some overheating issues that -may- be related to the write speed, not sure.Until class-3 cards become available (minimum write speed is 30MB/s if I recall correctly), which are for 4K video writing, this is about as good as it gets.Note that a higher speed where it says 45MB/s* or 90MB/s has to do with READ speed and it's a MAXIMUM value. It has nothing to do with write speed (that's the 1 inside the little U). Write speed is what matters if you're trying to speed up fps on your DSLR or trying to get better write performance for some other device.GL

This is my most used and relied upon SD card. I use it for my Canon Rebel t4i. Purchased and used since October 2013 and still going strong. Images have been deleted, transferred, and the card formatted many, many times. I will always purchase SanDisk for camera storage over competitors

Since version 10.7 of OSX dropped support for PowerPC applications, I've been looking for an easy way to switch back to version 10.6 (snow leopard) occasionally. This little memory card has proved to be fine for this. A minimal install of OSX 10.6 easily fits into is with about 24GB left free for data/apps. While booting can be a bit slow, its speed is fine for general day to day tasks once booted. A cheap way to keep a bunch of legacy OSs that don't work well in VMs around.

I have only just made a test compared with the SD Ultra by using continuous shooting mode in a Nikon 1 V1. The Extreme wrote 34 10MB+ jpeg files from the buffer to the card in about 30 seconds compared with about 70 seconds for the Ultra. If you need the increase in speed the card gives it. The Extreme was a couple of dollars less than the Ultra at Costco so the choice was an easy one.

It is noticibly faster than 30MB/s.I was happy with my SanDisk Extreme SDHC Class 10 UHS-1 Flash Memory Card 30MB/s until I used this one.A SanDisk product is trustworthy, and I don't feel comfortable using any other brands' memory card.

I can take around 20 pictures on my T5i without slowing down. The transfer is high enough for HD video as well. If you get a card of this caliber, make sure you have a USB 3.0 reader as well, to take complete advantage of its speed.

So far so good. I have had no trouble with speed and responds quickly with videos, etc. Great to have a good capacity for pictures. This is more that some of the others but I believe well worth the investment in gaining capacity and speed.

Card is noticeably faster than my 30mb/s. So far no issues with stability, and don't expect any. Have shot several full "loads" - approx, 2000 shots with the OMD EM5, and no concerns. Just wish memory in general was cheaper or more stable in price. Will be aiming for 90mb/s+ card in the future, if the cost would dip below 100!

Picked up one for the Nintendo 3DS XL. I've had no problems, and I frequently buy games digitally; the amount of storage for the price has been a real plus for the platform, unlike the Vita and it's overly expensive proprietary cards.

excellent

Cheap price and Great product

Good price for a a solid product. Package is designed for Amazon, a simple envelope style, close to bulk, but this is how we were able to get a better price.

Cette clef USB pour appareil photo est très rapide et permet d'emmagasiner énormément de photos et de films.Bon rapport qualité/prix.

The card captures the quality from my camera very well! Worth the price and if you are using a high end camera this is a card that you have to consider.

Bought this for my kid's 3DS XL. Works great, nice speed, and most importantly give him tons of room for downloads on his 3DS.

It work perfect with my new Sony HX200V cameraFaster than my old card for burst shooting (10 frames/sec)I recommend this product.
