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

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.

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.

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 IISandisk MicroMate

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

Worked as advertised. Still working
