At Least two of the Sony Packaged Memory's Pictured here on Amazon are FAKES or COUNTERFITS.


The people that make these are taking non-sony generic crap 512's, 1,2,or4 G size chips
and creating very elaborate nearly perfect (looking) FAKES! Zoom in and look very closely
at the model numbers for the 8 and the 16 Gig. In the third and forth images you can plainly see
the fake model numbers I have shown below.

Their numbers do not exist in the True Sony lineup.

for example: MSX-M8GST/X & MSX-M16GST/X do not exist <<< BOTH ARE FAKE

Dont believe me,, go look it up for yourself ,,, GOOGLE it or look at the links below.


for MARKII MS-MT8G & MS-MT16G Also there is an 8g that is not MARKII it is MSX-M8GS/X << older model.

There is never a T toward the end of the model number in these particular Larger memories,
and NO MARKII's ever have a /X or a MSX !!! in the model # at all!
This fake erroneous numbering scheme was barrowed from the 1G MSPD which has the number > MSX-M1GST/X

and from what I can tell is the only Sony Stick to EVER have the T in that location!

Take the time to look at these links which are both VERY, VERY Informative on the Subject.
Look In Comments for them:


You should also know there not just doing these Sony Memory Sticks. Sandisk and Lexar as well as all forms of
flash memories and USB Thumb Drives including Kingston, as well as Many Others are being FAKED....

Even though I have been slowly weaning myself off of the newer Sony cameras, I still have some Sony devices that need memory pro duo cards. There are some advantages and a few disadvantages, namely the cost and availability. Sony's memory format averages 30 to 100 percent higher prices for the same capacity of SDHC cards. While that sucks, if you have a Sony Camera or a PSP there's not much you can do about it.

To that point, both the new Sony Cybershot DSCT300 Digital Camera and upcoming PSP God of War Entertainment Pack will benefit from any of these memory cards. Both of those devices, along with most Sony devices for that matter are only comaptible with the memory duo platform.

But like I said, if you need one of these cards, there are some advantages especially if you get a Mark II card. Namely, the performance speed of the mark II format is about 50% higher than the fastest available SDHC card at the moment. The rating is for 36 MB/s and what I've seen through some basic tests seems to indicate real performance close to this. In fact, the solid performance has to be the biggest pro for these cards. So while it sucks to have little choice, when you factor in the premium performance it's easier to swallow.

The 2 and 4 GB cards are a better value than larger capacity ones right now. Sometimes you want the largest card you can get, but till the 8 and 16 GB cards come down I see no reason to buy them. Not to mention, this isn't for my primary camera but for an older one that I use as a backup.

Make sure your device is compatible with the card. Some older electronics aren't compatible with larger capacities, although in general Sony has been better with making these guys backward compatible than others.

It's always a good idea to have several extra cards on hand just in case. This 4 GB card is a nice performer. If you have a high capacity camera (10 Megapixels or more) and are storing videos or RAW images, the extra cash for the 8GB card may be worth it if the price is right. Or you may want to step up to the larger 16 GB size that is now available. But if you wait a little longer you can save yourself some cash. I have to take off at least 1 star for value, but in terms of performance I couldn't be happier.

I'm aparently also a victim of the fake cards. Ordered the 16GB Sony memory stick pro duo directly from Amazon. Received it (unaware of fake cards going around), formatted it in my PSP without problems. Then tried to load data to the card via my card reader. Card reader didn't recognize the card. Card reader was old so purchased a new one from Best Buy. Recognized the card but transfers were incredibly slow and data got corrupted. Checked with manufacturer of reader and they indicated they only tested up to 4GB. Bought yet another reader with guaranteed support for all speeds and capacities. Same problem. Checked online and found out about the fake cards. I already threw out the packaging believing the card readers to have been the problem. Amazon was kind enough to still ship me another card. Will wait and see if it is a genuine one. I would never have expected Amazon to be selling fake items...

This 16GB Memory Stick Duo II card works great with the PSP portable gaming system. It comes pre-formatted, so all you have to do is stick it into your PSP and go. In fact, there is a picture of the PSP right on the packaging.

The usable space on this device is actually 14.9 GB, however.

The "Mark2" certification on the card has to do with higher writing speed requirements and indicates the memory is certified to operate with AVCHD recording products.

This is currently the only available 16GB Memory Stick. I bought it for my Playstation Portable in order to replace an 8GB Memory Stick.
Regarding the price you can easily argue that it is much cheaper to buy two 8GB Memory Sticks. And for any person who is concerned about spending money I would not recommend this product.
At the time I bought it, Amazon was offering the best price online. Regarding the fact that this Memory Stick is about $50 more expensive than the PSP itself, makes you think twice. But my sole purpose was that I wanted to keep things together: my music, videos and saved games etc.
This Memory Stick is large enough to satisfy my thirst for disc space with a single solution.

The Memory Stick works fine in my PSP. Before this one I used a Sandisk 8GB Memory Stick Pro Ultra and I cannot see a difference in read/write speed (while connected through USB to my PC).

Final thoughts:
If you are concerned about spending money and you can live with more than one MS for your gadgets, you should get two or more 8GB MS. If you want a single solution and price is of no matter, get this one. Since it is from Sony you can be sure it works with your MS-enabled gadgets.

- high capacity
- read/write speed is up to par with other (higher ranked) memory sticks (using the PSP USB connection!)

- not cheap

5 out of 5 stars; simply because the price does not matter to me

(My guess is that the price will drop to about $150 once other manufactures offer similar capacity.)

All buyers be alert. I bought this item from taotao months ago and it did not work. it said 16gb but only 1 or 2 gb are usable. Asked for full refund but seller said once the package is open there's no refund at all. So I gave up. I can lose the money, I dont care. BUT, I'll never buy from this seller for selling counterfeit items. Please be ALERT when you buy from this seller.

Purchased this for my Sony Cyber-shot DSC-W150 camera based on the 25 great reviews before me. (Thanks, reviewers... I wasn't exactly sure what I was doing because the documentation that came with the camera didn't provide any help on how to buy memory!) I thought $38.50 was a great deal. It does the job and allows me to record video clips without feeling like I'm eating up all my memory. (For reference, about a minute and a half of video uses up about 200 shots out of the 2,500+ shots. Though I don't know if the resolution settings, etc. are factored into that estimate).

I bought this Sony MSMT16G 16GB Memory Stick PRO Duo (Mark2) Media Card from one of Amazon "Featured Merchant". It came with a very original look like packaging, even a hologram on top. As soon as I insert it in to my video camera it did not recognized. I tried another same type camera and also a media card reader with no luck at all. Then I found lots of information on the net saying there are fake ones which won't work with cameras and else. So be careful don't buy a fake one, like me.

I bought this mainly for my PSP. 16 gigabytes is very sufficient to store tons of movies and games and the best thing is there aren't any glitches at all. :D
