DriverHeaven Review



PSP owners should all be familiar with the 32 MB memory stick that comes included with the purchase of the Sony PSP. This small amount of space is capable of holding all of your save game files, as well as a few songs or a few minutes of low-quality video. With the release of the 2.0 firmware recently, the PSP is becoming less of a gaming device and more of a multimedia device. It currently supports a variety of photo and music files and can even display video in 4:3 and 16:9. However, a lot of owners are missing out on these features because of their 32 MB restriction.

Luckily, SanDisk has a clear solution for this problem. The SanDisk 1GB Memory Stick Pro Duo is capable of holding not just your save files, but also several full-length, high quality movies, hundreds of .mp3 or ATRAC3 music files or even thousands of photos. Obviously this seems like the right decision, but some PSP owners still have concerns involving performance issues. After benchmarking the SanDisk 1GB Memory Stick Pro Duo against the stock Sony 32MB Memory Stick Pro Duo, we can finally put all of these concerns to rest.

*Internet Speed* Internet benchmarks were performed on a cable modem with 500 KB/s max download.

*Test System* Intel P4 2.53 GHz, 2 x 512 Kingston PC2100 DDR RAM, Western Digital 80GB Hard Drive, Running Windows XP Service Pack 2.

*Transfers* All transfers performed via USB 2.0 port. Results are best of 5 trials.


Well there you have it, the SanDisk 1GB Memory Stick Pro Duo out performed the stock Sony 32MB Memory Stick Pro Duo in every single aspect imaginable. Strangely enough, transferring photos is unbearably slow on both devices, but that is more of a problem with the PSP’s hardware than the memory stick. Surprisingly, even the PSP’s web browser had noticeable speed increases just by switching to SanDisk’s memory stick. SanDisk simply outperforms Sony’s memory stick in every way imaginable.


Now that we’ve proven that the SanDisk 1GB Memory Stick Pro Duo is a faster file transferring solution, the only question remaining involves its worth. Unless you intend to just use your PSP for playing video games and nothing more, then you should definitely consider a SanDisk memory stick. The 1GB memory stick can be found for around $100 from most online retailers, and when the 2GB model is released we can expect prices to drop even further.

While there is no absolute answer regarding capacity, the best we can do is give approximations of how much data can be stored. Although it’s advertised as a 1GB memory stick, only 949 MB of it is usable from the start, due to system overhead. Depending on the length of the movie and the quality, you should be able to fit 2-4 movies on the memory stick without a problem. We managed to fit 2 ½ hours of high quality of footage with enough excess space to hold save games. Again, with the music the number of songs that can be stored also depends on quality and length. Roughly 350 .mp3 should be able to fit on the memory stick, but we would recommend going with the ATRAC3 format to save space without sacrificing too much sound quality. The file size of pictures won’t vary from the PC to your PSP because it is now able to support everyday files, like .JPG formats. In short, the SanDisk 1GB Memory Stick Pro Duo will be more than satisfactory for your portable multimedia needs.


In conclusion, the SanDisk 1GB Memory Stick Pro Duo is clearly the best memory stick available for the PSP. Not only is it the highest capacity memory stick on the market, but it also outperforms Sony’s memory sticks. Even if the 1GB version is out of your price range, SanDisk also has 128, 256, and 512 MB versions also in stores. Simply put, if you’re ever going to buy a PSP memory stick, buy from SanDisk.
