SanDisk 32GB MicroSDHC High Speed Class 4 Card with MicroSD to SD Adapter

I purchased two of these memory cards from seller "Everything But Stromboli" via Amazon.com. Both were genuine SanDisk cards and appeared to be new as promised. Some sellers are selling fake SanDisk cards so be cautious to make sure that the seller you choose is not cheating you with a cheaper substitute.I ran a thorough analysis on my cards and all 31,914,983,424 bytes of each card were "verified" with zero errors (it took slightly over 6 hours per card for this test!!!). The formatted capacity in a Motorola Droid X phone was 29.66 GB (which is normal for a 32 GB card---the formatted capacity is normally a little less than the unformatted capacity). Note: You should always format your card in your phone (NOT your computer) before you start using it. This is true even if your card came preformatted.I tested the write speed of the cards and they were around 5.4 MB/s (megabytes per second) which exceeds the 4 MB/s minimum for a Class 4 card. SanDisk has a reputation for rating the speed of its cards conservatively and this is definitely the case here. By the way, I have a couple of "Class 2" SanDisk cards that are even faster than these Class 4 cards.Further testing revealed that a Droid X (running Android 2.2.1) takes longer to mount a 32 GB card than a smaller card. Evidently the larger the capacity of the card, the longer it takes the phone to "prep" the card for mounting. This is probably because the FAT (file allocation table) is larger. I think this is normal and buyers should expect this from a larger card. The delay is noticeable when the phone is turned on and when the phone is connected to a computer via a USB cable in "Mass Storage" mode.I also noticed that my computer seemed to sometimes have trouble mounting the card via USB cable while it was in the phone ("Mass Storage" mode). I think this may be a result of the Droid X taking a little longer to mount/unmount such a large card---perhaps the computer times out while waiting for the phone to unmount the card. A simple solution was to toggle the phone's USB mode to "Charge only" and then back to "Mass Storage" while still connected to the USB port of the computer. By the way, there was never any problem mounting the card when it was removed from the phone and connected directly to the computer via a microSDHC-to-USB adapter. However, I prefer NOT to remove a memory card from a phone unless it is necessary because they are fragile and easily damaged.These are great memory cards and I'm very happy with my transaction with Everything But Stromboli on Amazon.com.Kind regards, D.Harris

theres not much to be said about Sandisk. They are one of the most reliable SD Card providers! easy to use on all devices that have it as an option!

I have a lg fortune 2 which in the cell phone world is considered "old" by now lol, but i still like it and wanted to see if i could use this to get more storage and keep it going. Well, im glad i did bc so far so good! If you're not that "tech savy" no worries! Just have to be a little patient while you do it. And if you think you messed up? Just take out the card and put it back in and then give it another try! Its great for games too that you dont want taking up more room. Note: if you do updates you may have to change it back to "sd card setting" afer the update bc i had to do it with mine but it was perfectly fine. Hope this helps potential buyers and thanks to the seller for an easy and affordable product that works!☺

Bought this for the Kodak Pixpro WPZ2 camera internal memory. Works great!

I adore these little microSD cards. I originally used it to send pictures and movies of our daughter to my husband while he was stationed overseas without us. They were so convenient and cheap to ship, and they could hold TONS of information. I love the versatility of it as well. Once we were reunited, I used it in our camera so we wouldn't miss any moments. Of course, they're really easy to lose if you don't keep track of them, but that just takes some organization to counter. I've never had a problem with either of the two that I purchased. They work in any device I've put them into.

Worked perfectly and as advertised. Once on Amazon I got a fake ad card. But Amazon jumped right on it and I immediately got a refund. I was nervous of course to try to buy one again but this time it was clear sailing. I think Amazon works hard on making sure stuff like that doesnt happen. The reason I know the card is working just right is because I also bought a new bluetooth speaker that you can attach to your bicycle handlebars. The speaker can broadcast music from local FM stations, from bluetooth (like google play, iTunes, pandora or whatever on your phone) and it also has a slot for a micro sd card. The very first thing I did was transfer all my purchased music onto the micro sd card and then put it unto the micro sd card slot on my new speaker and voila! It worked perfectly. I cant wait to try everything on the road!

I was really concerned about all the negative reviews and many claiming they received a knock off micro sd card. I read hundred of reviews and based on feedback and a 99% rating I bought my Sandisk 32 gb class 4 micro sdhc from Calvin N Hobbs. I ordered it about 11:30 PM on 7/17/2012 and received it about 3:30 pm on 7/20/2012. Now that is fast shipping! I also wanted to let everyone know it is a genuine card with the serial number on the front of the card. It did not come with the 8"x11" red retail card with the blister pack, probably due to the size for shipping a tiny card & adapter in a 2"x 2" case. The micro card & adapter came in a small plastic Sandisk case in a small padded envelope. I formatted it and loaded about 25gb of pictures/video and music and it works great in my Archos Tablet. Read an write speeds are typical of the cards I bought at best buy for much more. It exceeds the class 4 base standards and much faster than the 8gb A-data it replaced. There are so many sellers on Amazon, be sure to do a little research before you order. Calvin N Hobbs sells OEM genuine cards. They weren't the cheapest.... it did cost me about $0.12 cent more to get a genuine card.

works very well

Good value, I bought it for a trail camera and it does its job.

good

Only got one piece. Supposed to be sd card and adapter. Adapter was missing.
