SanDisk 16 GB microSDHC Flash Memory Card SDSDQ-016G (Bulk Packaging) - Class 4

After getting jipped twice on ebay for a microsd card (one never came and the other one was a defective 16gb kingston class 4) I decided to buy from Amazon who I trust and a brand I know my phone works with. Needless to say its the best decision I could of made for my needs. Everything worked perfect after transfering all my data over from my 8gb sandisk class 2, apps saved to sd, roms, music, ebooks, etc, there wasn't one file missing or any problems on my Evo 4g. The best part is that card is a lot fast than you would expect and made me realize I would of seriously wasted my money if spent a lot of money on a higher class. Like I said before I came from a 8gb class 2 sandisk and kinda expected this to be slightly slower because of the larger amount of space or the same speed. Unbelievebly this card is faster than my 8gb and guess what its exactly is a class 4 in speed. I've done a sd speed test twice on it one while it was empty and another one with 12gb of data on it and it was classified as a CLASS 4 both times. Its write speed is a minimum 4mbps and its read speed is a minimum 4mbps. It doesnt take long for large amount of data to be put on the card. So unless your a developer where every sec cost you money your going to be satisfied with price and speed. I did buy from a Amazon recommened seller and used a free amazon prime trial which it got here 2 day like stated. There are probably more fake cards on the market than legitimate ones these days that why I highly recommend buying from a amazons recommended seller. I speak from experience its not worth the risk of getting a fake or defective which end up costing you more time and money to save a couple of bucks.

What I bought: Sandisk 16gb micro SDHC card (bulk packaging) I bought this in December 2010 as a small Christmas gift to myself. I have been using it routinely since then and have experienced no problems (it's May 2011 at time of writing). I can understand why many would be wary about purchasing something like this in such a shady way (low price, bulk packaging, over the internet), but hopefully this review can allay some of your concerns. My card came pre-formatted, had the correct capacity, and has worked flawlessly in both my cell phone (LG enV) and my Nintendo DS Lite flash cartridge (Acekard 2i). No recognition errors, no lost data, nothing bad to say about it. Transfer rates were more than adequate for a class 2 card. I commonly see read/write speeds above 3 MB/s (class 2 cards are only required to keep a minimum of 2 MB/s). Not exceptional for an SD card, but when it only costs you $25 you'd be foolish to ask for more. While my experience has been positive, I've seen some 1-star reviews with claims of faulty or mislabeled cards. I can't say for certain, but this may be a result of the seller, not the product. I purchased my card from KEFERS, so it might be wise to do the same if you have the opportunity.

I purchased this card because we use MicroSD cards for everything. They have adapters for USB and full sized SD cards so it works in Digital Cameras, the Nintendo DSi XL, X-Box 360, and our computers! I had tried Class 4 and Class 6 MicroSDHC cards on the X-Box 360 (not the Slim model) and they worked well, meeting the performance requirements to copy a game to them, and play it off of the memory card. I was not sure if a Class 2 would work, but it would be a bargain of a price! This Class 2 MicroSDHC 16 GB memory card worked perfectly! We did not notice any performance differences between it or the internal hard drive, or the higher class memory units. This little memory card is exceeding expectations! I am impressed! If you need a low priced memory card that will work as an X-Box 360 memory card as well, this is the one to get! ***EDIT***: I have gone through more testing, and it seems that the Memory Card Reader itself holds this card back most of the time. Out of 5 readers I have tried, only 2 of them will result in meeting X-Box 360 requirements, whereas the other 3 do not. I can still play games from the USB card with the slower readers. These readers worked best: elago Mobile Nano II Sandisk MicroMate

Never had a problem with it, used for mobile phones and other gizmos that require memory cards.

Good memory like all SanDisk's

My biggest concern was the compatibility of this card. I bought it to replace the stock 8GB microSD that came with my Droid 2. Its turned into my mp3 player so needed more storage. If you have a droid 2, and I believe any other "droid" product, this is 100% compatible. Perhaps I'm biased as my former mp3 players were apple products (nothing wrong with them, but I didn't see the point in having both items and gave my ipod touch to my sister) but being able to double your memory for $20 is a great deal. This also came with a micro to normal SD converter, which was a nice perk even if I doubt I'll ever use it. Though perhaps it will fail, I have had no problems with the same brand microSD card that came with my smartphone in the last 10 months; so I don't see any reason it would (just remember that when hooking it up to anything, you need to properly eject it before removing the connection; otherwise you risk damaging the card in a similar way to shutting down a computer using just the power button constantly). Basically, this does what it does at a good price and even came with bonus accessory (it was in bulk packaging too for the record). It is plenty fast for non-camera use too.

Let me start by explaining my particular lack of knowledge of this technology. It is beyond my ability to comprehend how so much information can fit onto such a tiny card in the first place, so I feel as though I cannot do justice in describing its full potential as a useful device. I cannot accurately rate the device because I have little to compare it to. However, I will say that, for the purpose for which it was purchased (extra storage for an audio player), the device has functioned as promised. It is for this reason that I give the item an overall review of three stars. Additional ratings follow below. General Performance: 3/5 The device malfunctioned on my first attempt to use it, which immediately knocked it out of the running for anything less than dead-center average. The malfunction occurred when my music software failed to sync properly with the card. Not being familiar with the error, I removed the MP3 player after stopping the sync, but the player had not finished "refreshing media". This caused an error which totally locked the entire system, forcing me to run down its battery to cause a reset. Once I was able to reload the player, I used my computer's SD reader to format the SDHC card (the item up for review) before attempting another sync. With a $50 player and a $40 card on the line, it's fair to say frustration was high. After repairing the error and formatting the card (a procedure which was never expressed to me as being necessary to the operation of the device), the software was able to sync properly, and the player responded normally. Storage: 4/5 This card stores my entire collection of CDs, which easily numbers in the high 20s. Even though the player's internal memory (4GB) is still totally unused, the SDHC card has accepted my entire collection using only half its rated capacity. The only reason this rating did not achieve five stars is its inaccuracy. The device is listed at 16GB, and delivers only 14.5. Value: 3/5 This rating could not be higher because prices are forever falling on any new technology. As newer cards come out, this one will get cheaper and cheaper over time. The rating is not lower because I felt that the price-per-gigabyte was not overly expensive (when compared to other cards). Any local store which sells these cards is trying to charge me $20+ for half the space. This is why I purchased the device from this seller. Speed: 3/5 Again, I have to rate this attribute as average because I do not have enough experience with the technology to give it a fair assessment or comparison. I was neither impressed nor disappointed by its load, read, or write speed. It is entirely possible that other cards may respond faster or slower, depending on the purpose and application. Durability: N/A I did not rate this attribute because I have not owned the device long enough to assess its longevity. Overall Rating: 3/5 I was satisfied with this purchase, and would acquire another card if I had enough music or other data to store on it. I would recommend this product to another buyer, but only if the information necessary to its proper use is supplied, either via seller communication or included documentation.

I plugged this into my Iconia A501 Tablet and it didn't work. It took a bit of research to find out that most likely this memory card was not formatted. In order to work in the Iconia A501 (or probably any tablet) it would require formatting to FAT or FAT32 protocol using Windows. This turned out to be relatively easy as I have a computer with an SD Card slot but I had to use an SD Card to Micro SD Card Adapter which luckily I already had in one of my cameras. You will have to go to the Windows Control Panel and get to Disk Management then find the SD Card in the list and then format it to FAT32! After what I thought was the initial format, it asked if I wanted to format the SD Card and the first time I said no, but you should say yes and this is when it will actually format it correctly. After that I plugged the micro SD card into the Iconia A501 Tablet and it now recognized it. A real bargain for adding 16 GB of memory to a tablet.
