==========
I have tested dozens of SDHC and micro-SDHC cards. One disturbing trend I noticed is that: the speed class rating for micro-SDHC is typically inflated. For example, a 'class-10' rating means the card must deliver a sequential write speed of at least 10MB/s. But somehow, a class-10 microSDHC cards is always slower than a class-10 SDHC card from the same manufacturer. Case in point: the PNY 32 GB microSDHC Card (P-SDU32G10-EFS2) claims to be 'class-10', yet it can only write at 8.6MB/s maximum, while the full-size PNY P-SDHC16G10 achieved 13.4MB/s according to CrystalDiskMark v3.01.
This SanDisk Ultra 32 GB microSDHC Class 10 card (SDSDQUA-032G-U46A), however, proves to be the exception. It achieved a sequential write speed of over 10MB/s according to two different benchmark programs (11.8MB/s in "CrystalDiskMark", 10.6MB/s in "H2testw v1.4"). This is faster than all my other microSDHC cards, including two 'class-10' cards from PNY and Polaroid.
A closer look at the file transfer speed using "Flash Memory Toolkit" revealed another nice surprise: For writing small files, this Sandisk Ultra microSDHC card performed just as well as its full-size counterpart, the SanDisk Ultra SDHC (SDSDU-032G-AFFP). In contrast, all my other class-10 microSDHC cards perform poorly while writing smaller files. See the benchmark results I uploaded to 'Customer Images' for details.
When you use a memory card in a digital camera to record HD video, it needs to store a huge video file each session. That means its sequential write speed is most critical. When used in a tablet or a smart phone, however, the card's random write speed for small files is more important. That's why in such applications, the Sandisk microSDHC will perform faster than the PNY and Polaroid cards, even though they are also rated as 'class-10'.
[Bottom Line]
As of this writing, the Sandisk Ultra microSDHC card ia actually priced lower than other class-10 cards from PNY and Polaroid. This makes the Sandisk the best value especially if you need honest class-10 performance across all platforms.
[Side Notes]
Do not confuse this Sandisk Ultra card with SanDisk Mobile Ultra microSDHC (SDSDQY-032G-U46A). The latter is rated for class-6 only.
The size of this '32GB' card is 29.7GB according to my computer. This is actually normal because computer people count one Gig as "2 to the power 30", which is 7.3% larger than one billion. So 29.7GB translates to 31.9 billion bytes, which is '32GB' according to marketing people.

Works great with my Galaxy S3. Didn't need to format the card or anything. Just popped the card in and everything worked great out of the box. Transfer speeds are excellent with this card. I would recommend this card to everyone.Read Best Reviews of SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 Memory Card with Adapter Here
Initially when I inserted the card into the Samsung Galaxy S3 it recognized it but it wasn't able to format it correctly. After doing some research I found a free program EaseUS Partition Master that will format the card into FAT 32 since Windows no longer allows you to do it by default. After formatting it into fat 32 the phone recognized the card and it works great now. I hope this helps anyone else that might run into this problem.Want SanDisk Ultra 32 GB MicroSDHC Class 10 UHS-1 Memory Card with Adapter Discount?
If your card gets hot enough to be painful, it is defective and you need to contact SanDisk!From my experience, the larger micro SDs run hot on format and writing, but not to the pain threshold!
I purchased one of these cards to use in a camera and Android tablet. Great read speed but write speed was okay. Used card for about two weeks and then all my files disappeared! Tried to format the card and three different computers with XP, Windows, and Linux couldn't format it. The camera and tablet couldn't format it. I RMA'd it and got another because SanDisk is a good brand. I did notice that when formatting or writing the card it got hot, very hot.
Second card didn't last 24 hours and had the exact same symptoms as the first card. Write a file or format it resulted in the card getting hot enough to reach the pain threshold. I called up SanDisk and while explaining this was the second card I'd received with the exact same symptoms, when I mentioned it getting hot, they immediately issued me an RMA. They said they were told to issue an RMA the moment they heard a card ran hot.
Smaller SanDisk micro SD's or regular SD's I have or use don't do this. I think SanDisk has an issue with this card.
The last 4 digits of the part number refer to the date code and origin of the card. Both cards had different date and origin codes.

The last few days I have been diligently shopping for a MicroSDXC card to utilize in my new smart phone. I have a long term positive experience using SanDisk cards. I quickly became confused about the differences between the so called "Mobile" Ultra cards and the Ultra cards. The performance specs to my "intermediate tech experience" eyes were virtually the same. The prices were also similar, with the "Mobile"version slightly higher. To finally resolve my confusion I contacted SanDisk technical support. To my surprise, the "Mobile" version is the older, no longer manufactured version. The Ultra is the current model. So I immediately bought the current Ultra version, which very fortunately AMAZON had on sale!
