Summary: Same technical specs as the "faster" cards marketed for video and high speed photography. In reality, this is mostly a marketing difference, and you won't notice a difference. This one will do.
Pros: Sandisk and Sony are the only two real manufacturers of Memory Sticks, and Sandisk makes most of Sony's sticks -- only the plastic casing will be different. So this is an excellent buy.
Summary: I, as a lot of other people on here, purchased this for my w810i. It works flawlessly, storing music, pictures, video, everything... I loaded UBCD (UltimateBootCD) onto it for emergencies. This is a great product, the only reason not to buy it is if your device will support a larger card and you have the money to go that route.
Pros: It's a flash card at a great price. There's nothing exceptional about the product itself, it either works or it doesn't. The price, ease of purchase, speed of delivery, and wonderful support that comes with purchasing it here, on NewEgg, is what matters.
Pros: Just as fast as the Sony memory sticks and cheaper. Plus it actually has 3.9 gigs of space!!! I use this for my PSP only so I can put movies on it (I don't want to pay big $$$ for the UMD's when I already own the movies...)
Summary: 8gigs is suppose to come out next month. Wait to buy this so you can see what those are going to cost. All in all, happy with this product.
Pros: When purchasing a new DUO stick for your Playstation Portable, never buy Sony brand. (sorry sony) The Sandisk products are generally much cheaper and the tested speeds are faster. There is rumor that these 4gig sticks are slower than smaller sized ones, I have not found that to be the case. I used HD Tune and between my 1gig Sony, 1gig Sandisk, 32mb Sony(came with psp) and then 4gig Sandisk, theres little difference in the Sandisk products, ALOT in the Sonys. Do your ...
Cons: Honestly, I wish it had more capacity still. If your into homebrew and running backup iso images of your own games, 4gigs can be filled with a snap of the fingers. The card is alittle slow but still faster than the sony versions.
Pros: The Sandisk was always known for great quality. (BTW, I'm just going to use this for my PSP console.) But this is the all mighty 4 GB stick. It's a GREAT improvement from my sorry PSP 32 MB memory stick. I can't say enough about the product. Also ordering and getting it 2 days later, I'd say it's just great. I put a 1.3 GB file on the memory stick and I'd say it transfered under 5 minutes. Now compare that to a Sony memory stick. Also, 4 GB is a great bit of room, you...
Cons: Cons? There are plenty of them. First of all, it's very easy to CONtrol your memory, such as putting files on and transferring them onto the pc. Its great value price will have you CONcentrating on it for a while until you buy it. I hearby CONclude this as the best 103.98 dollar(s) I've spent in my life on something so beneficial. Thanks Sandisk for such a good product, and Newegg for such a great price.
