Additional Information


Bought this, actually the SD version, 8 years ago for my Canon digital camera. I was using it with no issue until this year. One day it stopped working all off a sudden. luckily i back up all my pics and videos before. it had lifetime warranty that time (which is now limited to 5 years), I got in touch with customer service, they didnt even ask me to prove bill or sth which I dont have anymore. I just told them I bought on Amazon, this and that. they asked me to send a picture of card and enter the serial number on the the web return page, and return the defective product with shipping covered by them and that is it! one week after i received my new card. Sandisk is reliable brand. they never regret me so far.

5 stars!

I just installed SanDisk 32GB MicroSDHC Card (SDSDQ-032G-A11M, US Retail Package). Purchased the card from with Amazon as the seller. The price was $10 more than other sellers, but I bought it from Amazon for two reasons. First, I know I can return it if it doesn't work. Second, the card has been out of stock from Amazon for a couple of weeks, so I was confident that I would get a Class 4 card that was recently manufactured, not a Class 2 card that had been in inventory for months. Well, lucky me, I did receive a Class 4 card today.

Previously, I owned a 30GB ZuneHD. It was probably my favorite appliance, over my lappie and desktop. I used it everyday and everywhere. My new Samsung Focus i917 was hard to adjust to, as 8GB is not enough space after being used to the ZuneHD. So, I am risking it and trying the microSDHC card.

I will be diligent to post updates today and in the following weeks to keep everyone updated on how well the card is working. I am syncing 34+GB of music, videos, pics, and podcasts right now. Stay tuned for the results. Here's to hoping for flawless performance.


Ok, Two days in and the card has been performing very well. I have had one studder/freeze with a restart. I have had the phone for about three weeks before buying the microsd card and it had frozen/restarted once, so I cannot contribute this behavior to the card.

One note of strange behavior *After installing the card, I wanted to fill it up :) , so I told the Zune software to sync alot of music, podcasts and videos before I went to bed. While syncing througout the night, I could tell the phone had restarted by the bright screen glowing off of the ceiling. And restart it did. I was sleeping most of the time, but I would estimate the phone restated about 10 times throught the night. When I woke up, the phone had 11GB free.

Although there were multiple restarts while filling the card througout the night, like I said, it is going FINE in day to day operations. Promise to update again in a couple days.

Cheers, M

Ok. Another week with the card and it has been perfecto. I am very glad I took the plunge and spent almost a benjamin for this. My phone has not had one issue this week, even though it has been filled to 2GB free.

This card has my 100% reccomendation for the Samsung Focus.

UPDATE: I have used the card daily for nearly 30 days. The card works perfectly. I have not had one reset, failure, error code, or problem with the phone. Apps and games load in the same time they did before I installed the card. I am very impressed with my experience. I sure wish Samsung or Microsoft would release a list of supported cards so that everyone could have the great experience I have. Again, I ordered through Amazon, for a few bucks more than the other vendors, but I received a class 4 card.

I bought this together with the dash-cam I bought it for. At first, I blamed the issue of only the first few files being usable on the camera and during the course of trying to verify this card as fast enough, instead I uncovered that it is a fake. Only 2GB were usable, and after formatting it twice, it is no longer usable and only reports an I/O (input/output) error. I have a small collection of MSD cards by SanDisk, and after finding all kinds of articles online about counterfeit SD cards, I took a look at all of the, and this one doesn't match.

Quick background, I have been in the computer industry for nearly 20 years, and can say with certainty that this card is not what it is supposed to be. I wasn't aware of how prolific this counterfeit issue is until this. I have to share and agree with SanDisk's PR statement, buy these in person, at an authorized vendor. There is no way to know until after you try using it if it is a fake when you order them online.

The card I got was labeled class 4, but was on par with the over-performing class 2 card. I assume SanDisk simply decided to start calling the class 2 card class 4 since it gets over 4MB/s sequential writes.

My card was shipped from BlueProton in late December 2010.

These are my results using a USB card reader:
