How Much Can You Store?
Capacity Matrix

Choosing the right capacity very much depends on the type of file you want to store. Full HD³ videos, for instance, take up much more room than a simple snapshot. Music files vary in size depending on the format they're saved in. To help you make the right selection, this matrix uses typical file sizes to illustrate how much each capacity is likely to store.

Size: 16GBPackage Type: Standard Packaging Verified Purchase
After purchasing many Sandisk cards, and having some problems, after researching up I found some main points.

1 - Sandisk are the most brand currently counterfeited, and it is getting harder to check and find real working ones.
A - The printing on the fake products has got better.
B - The packaging printing is perfect on some fakes.
C - Even the hologram on packaging is perfect on some fakes and some are using stolen ones from Sandisk.
D - Sandisk will say that do not buy micros if they come with a adapter as they are fake as they do not put adapters with micros. This is not true, Sandisk do supply them, they are made by Hama for Sandisk, and the micro cards are real.
E - Some fakes are infact real, they are real Sandisk cards which are faulty in some way, these are then stolen from the factory and then altered. So these packaging, hologram and card are in fact real but faulty. These serial numbers will come up on Sandisk warranty as destroyed at factory, and on return to Sandisk they will confiscate them and not refund a card or money as it is stolen property. You will just get a letter saying just this.
F - Fakes are either OK and working with the size purchased but made by some one else, a cheaper rebadged maker/factory.
G - Fakes are either not OK and not the real size you purchased. Thus either a real Sandisk card mainly 4Gb altered to look like your size, or worse a fake did made by some one else. This can be a size or speed issue ie. States it is a 10 but is a 4, or standard SD instead of hcsd or xcsd.
H - To make thinks worse. In 2012 Sandisk made some cards wrong and they got out of the factory by the millions in various packaging, these mainly are Ultra.

I purchased two of these cards in early January - one for my wifes HTC Desire C and one for my own Galaxy S3.
Within the month, my card stopped working. The phone could not recognise the card and neither would my PC so I was unable to try reformatting it. I have returned this card to Amazon for a refund which is in process. My wifes card is still working ok.
In parallel with this return, I have been in contact with Sandisk and they have confirmed that my wifes card is not a fake as it has a serial number on the reverse which they have validated. My card (although purchased with my wifes) has no such serial numbers on it. Sandisk advise that these can become "rubbed off" but advise purchasing only from Amazon directly and not one of their resellers on their MarketPlace. They can't say conclusively, but I believe my card is fake. You can register your card with Sandisk and I would recommend you do this if you buy one of their cards to find out quickly if you've been supplied with a dud - you only have 30 days in which to return your card with Amazon so be aware!

Size: 64GBPackage Type: Frustration-Free Packaging Verified Purchase
I have never got reliable operation from this card which I bought in February. I had thought it might be something I was doing, but having tried it in different devices and using different card hosts it remained unreliable. I have messaged the seller but they have not responded.

This week I gave up and contacted SANdisk direct to invoke warranty. I sent them photos of the card and today they have informed me that it is a counterfeit product. So now, unless Amazon give me a refund I reckon I am out of options and will have to buy another card.

Thanks Amazon! They gave me a full refund so I can now buy a proper working card. No more Amazon resellers for me. Only buying direct now.

just to let you know I brought this from Amazon (they are an authorised scandisk dealer). I had to wreck the packaging to get at the card, so in this respect it seems a genuine product (compared to knock off ebay copies for which the 'retail' card was only glued at the corners), plus there are reference numbers on the back of the card (though I have not checked with scandisk about these numbers).

This micro SDXC Card was reported as damaged when I inserted it into my phone, tablet and computer (I assume because they don't natively support SDXC formatted SD cards). Neither my phone or computer would re-format it into FAT32 or anything else acceptable (I tried the windows formatter, command line formatter and a couple of downloaded formatters including the one from the SD organisation, none worked). Luckly my trusty HTC desire HD automatically reformatted it into a format that was accepted by the computer and tablet as well, hurrahhh!! Suddenly the supposed 32Gb MicroSD card limit on my new Samsung Tab 2 and HTC Desire HD is blown away!!!

Windows reports it will take 2 hours to fill the little disk. therefore at that rate it would be about 9 Mb/s which is high (remember this is the write speed), or rather this is about right for a class 10 product.

I will report back with a full review shortly.

In short nice little card with a big memory, but beware if you don't have an SDXC compatible device or some means to re-format the disc, otherwise you are looking at a pricey tiddlywink.
