At first, I was wary about getting a large memory stick for my PSP, because I wasn't sure how it would function. Online forums spoke of long transfer speeds, product ceasing to work after a couple of months, and even the PSP itself not being able to handle a memory stick of such large size. Well, I am happy to report that none of those concerns turned out to be reality. I went from a 2gb memory stick to this 16gb one, and the only difference I noticed is that the transfer speed is a little bit slower. And if you're downloading things from the Playstation Network directly, the download time is a nightmare anyway so a little bit longer shouldn't bother you that much. I've had this product for almost a year, and have had no problems with it whatsoever. I've got full games, demos, game saves, music and videos saved and still have about 8gb free. This is the perfect memory stick for you if you don't see yourself ever needing something the size of a 32gb, yet want to have one large enough that storing media never becomes a problem. However, I feel it is important to note that upon formatting the memory stick the PSP automatically utilizes 2gb, so be prepared to live with 14gb. Not a deal-breaker, but you have to wonder why something that doesn't even have saved settings yet would require so much space. A great buy I found online for about $60, considering 2gb run about $20 in store. Avoid buying off brand, as they tend not to last and sometimes don't even fit into the PSP at all.
