1) Formatting this memory card as FAT32 appears to come with some performance penalty: it took more than 3 hours to copy all my music into it. Even adjusted for size, this is a few times slower than what I was getting out of my trusty 32GB memory card. Early adopters beware.
2) Make sure you format this card with your cell phone. It comes formatted with a file system not currently supported by gadgets.
If you just want someplace you can stuff all your music for your phone or media player to play, this would be it. If you want performance, then you are better off with two 32GB cards. I can't tell you if having a microSDXC-rated device makes a difference in performance. Maybe, maybe not.
Most Helpful Customer Reviews on Amazon.com (beta)
One last note- to anyone who still doubts that it might work in their smartphones, the adapter that comes with it says "micro SDHC" not "micro SDXC" leading me to believe there probably isn't a whole lot of difference between the two if SanDisk is too lazy to make new adapters to make us think there is.
The card arrived in real retail packaging, and as far as I can tell, is a genuine Sandisk product. Included were some coupons for music downloads (in the trash) and an SD-to-microSD adapter. No problems there.
This card won't work as-is. It comes formatted with a new version of FAT, called exFAT. This allows the OS to take advantage of the card's size while providing an across the board file system for devices. To the best of my knowledge, the only difference between XC and HC is the file system - the card itself has the same electrical interface.
To make this card work, you'll need a couple of things. A machine with either a SD card reader, or an external dongle device, and some programs. Windows will no longer format drives larger than 32GB, even with the command line trick. So, search for a fat32 formatter program. I used fat32format from Ridgecrop Consultants, Ltd. It's a free command line program, and only does one thing. Search for it and you'll find it on the first page of results.
After the card was formatted, I installed it into the phone and booted, and checked the SD card. 59.4GB! Yes! I formatted it again on the phone to make sure everything was good, and copied the files from my old card over. No problems, and I have something like 40GB left.
If you're lucky, your phone will format this card direct. Mine wouldn't. I keep the fat32format program on the card now, just in case.
So, in conclusion:
Works fine on a Sensation with Gingerbread 2.3.4, firmware 1.50.
Format it on a computer first, use a fat32 formatter
Seems legit, running for a week now with no issues.
Speed? Don't know. No noticeable difference between this and the last device.
Music downloads? Yawn.
Included SD adapter works with all microSD cards.
If you want it cheaper though, go directly to the SanDisc website where they sell it for only $220!
