Memory Stick Pro and Pro Duo: More Storage for your PSP

In addition to being useful in cameras and cellphones, Sony's Memory Stick Pro and Pro Duo are also used in Sony's PlayStation Portable console. Because they are the primary means of storage for the console, you can never have too much space. If it isn't game saves taking up the space, it might be music and videos, or movies. With all the media available for the PSP, it's no wonder that space might be a little hard to come by.

That's where we come in. Our Memory Stick Pro and Pro Duo cards are an inexpensive way to carry more game saves, more music, and more movies with you wherever you go. Even using a great deal of compression, a movie might take up nearly 256MB - leaving you almost no space for anything else. But for less then $45, you can pick up a 1GB stick and carry two or three movies with you, and still have room for music, game saves and more.

Interested in playing music on your PSP? Even a simple 256MB Memory Stick Pro Duo card will allow you to carry four hours of music with you, even more with a larger memory unit. The same size storage device lets you carry whole albums of photos with you to share with friends or enjoy looking at yourself.

The cards come in storage sizes that make all of this possible. MiniSD and microSD come in 1GB or 2GB sizes for less then $40, and if you just need a regular-sized SD card for cameras or PDAs, there are even 4GB cards for less then $60.

SD memory cards are convenient and portable - the largest SD card is 24mm by 32mm by 2.1mm thick - or roughly an inch square. This allows you to worry less about the space your data storage is taking up, and you can easily take more then one card with you in case your first becomes filled up.

Flash media is also durable - unlike camera film or notebook hard drives, SD memory cards can survive being shaken around, exposed to sun and heat, and can even survive getting wet, as long as it's entirely dry before being put inside a device again!

So if you've been looking for SD cards, whether for your cell phone, PDA or camera, take a look at what we have to offer. In addition to the various types of SD memory cards mentioned here, we also offer HDSD cards if your device is one of the newer ones that takes advantage of this new standard. You should be warned that your HDSD cards will not work with non-HDSD devices, however.

SD Memory Cards For Every Need

SD memory cards are extremely versatile in where they can be used. Depending on the format, SD cards are usable in cell phones and PDAs, in cameras and computers. It's even possible to plug them into game consoles such as the Playstation 3 and the Nintendo Wii. Because of all the places in which they are used, they are great for transferring data around.

For example, you can take a set of pictures with your camera, take the SD memory card out and put it into your game console to look at the pictures on TV. Or you can take it to your computer and, with a card reader, plug it in and save the pictures to your computer's hard drive. You can also use your computer to download a java game for your cell phone and place it on your cell phone without being charged service fees for downloading data to your cell phone.

You can also use the same cards in multiple places. The smaller microSD and miniSD cards come with adapters that allow them to be used in regular Secure Digital devices. This would allow you to use the same SD memory card in your camera, and then take it out and put it in your PDA to save some documents before putting it in your computer's card reader to save your documents and pictures before clearing the card for other uses.

Deciding the Best Time to Buy RAM

When deciding to buy ram, how much is enough? That depends on what you want to do with your computer, and what your budget is. On average 1GB of RAM total is a good amount if you’re running windows, use your computer for surfing the web, but don’t use highly intensive software or play modern games. If you are a gamer, you'll need at least 1.5GB to 2GB of RAM or more to avoid slowdowns. Many people are taking advantage of the current low prices in the ram market to upgrade to two gigabytes of RAM, as the price is similar to what it cost for 1 gigabyte of ram just a year ago.

If you're worried that your system won't be able to accept more RAM, please take advantage of our online system checker. If you're surfing our website from the computer you want to upgrade, click the 'Check My Computer' button and it will return the best memory upgrades for your computer, including letting you know how many memory sockets your computer has and what speeds of memory it will take.

If you already know what type of RAM you're looking to buy, click one of the links on the sidebar and check out our RAM selection. We carry all types of DDR and DDR2 memory, as well as many of the same speeds and types of laptop memory. Our RAM is produced by some of the best quality RAM manufacturers in the business, including Micron, Infineon and Winbond. Always remember, OEMPCWorld.com offers free shipping, and we buy back your old ram!

Deciding the Best Time to Buy RAM

Is now a good time to buy RAM? Whether for your laptop or your desktop computer, RAM prices are low right now – and many people who are upgrading to the latest version of Windows Vista find the need to investigate a memory upgrade at the same time. RAM for your computer is both affordable and comes in larger amounts then it ever has been before. At current you can find 512MB for less than $40, and a gigabyte of memory for less than $70. At the same time that RAM prices have fallen and quantities have grown, so have the needs of the applications we use. Even the most critical programs, like Windows Vista, need more and more RAM these days to use without slowdowns or lockups.

Windows Vista recommends a gigabyte of memory to use the higher-end features such as the Aero desktop, and games are beginning to recommend having a gigabyte of memory or more for best performance. These memory needs are only going to grow, and it makes it critical now that if you don't have this amount of RAM that you pick it up, especially if you are looking towards upgrading your computer to use Windows Vista.

When deciding whether to buy or not to buy RAM it’s best to look at the current performance of the software that you spend the most time using - while programs are on the horizon that require a great deal more RAM, they have just been released and are not the standard, yet. You may have no particular need to upgrade your software right now.

Laptop Memory Upgrades (cont 3.....)

Other then the physical differences, DDR2 memory runs at a higher clock rate then DDR, and thus can send more information per clock cycle. The clock cycle is a synchronizing cycle used by computers to keep data being sent and received at the same time, so that the data flows smoothly rather then bottlenecking at odd points. This prevents data being sent in bursts and then having to wait for the processor or RAM to process it. It also means request that data be resent that might have been lost while other data was being processed do not occur.

Despite running at a higher clock rate then DDR memory, DDR2 memory is slower internally as it requires more organization to match the higher external clock-rate. This means that while DDR2-533 might seem like it's much faster then DDR400, the difference isn't so great that you should throw out your old laptop and rush out to buy a brand new one. With more memory, your laptop with DDR400 can outperform a laptop that has DDR2 memory.

Laptop Memory Upgrades(cont....)

Fortunately, as RAM prices have dropped for traditional desktop machines over the past couple of years, so too have prices fallen for laptop memory. OEMPCWorld.com offers 512MB of DDR400 laptop memory for a cost of only approx $50, and one gigabyte of DDR400 laptop memory for a cost of only approx $105. For newer laptops, memory is even less expensive - often less then $40 for 512MB of DDR2-533 memory, and less then $80 for a gigabyte of DDR2-533 memory.

Finally, it isn't hard to upgrade your laptop with more RAM. While you will want to consult your manual to determine the exact process for your laptop, most machines provide access to at least one if not both of the memory sockets under a panel in the back. By simply unscrewing this panel, users can add more laptop memory to their notebook computer quickly and simply. Be sure to check your warranty information card to see if this action may impact your service agreement.

What types of laptop memory are available? We carry almost every type of memory for portable computers in existence, from 100-pin and 144-pin SDRAM for older laptops, ranging in size from 32MB to 512MB, to newer 200-pin DDR and DDR2 memory, from 256MB to 2GB per module.

What's the difference between DDR and DDR2 laptop RAM? Despite both being 200-pin memory, they are physically incompatible, and won't work in each other's sockets. DDR memory has a notch near one side of the RAM at the base, where the pins are. This 'keys' the RAM and makes sure that it can only be installed the correct way, preventing the RAM from being accidentally installed backwards. DDR2 also has a notch, but its is located nearer to the center of the RAM. These two different keys prevent DDR2 memory from being used with a DDR controller, where they would not communicate correctly, and vice versa.

Laptop Memory Upgrades

While your laptop is asked to perform the same tasks as your desktop computer, it isn’t always as powerful, nor as quick, simple, or inexpensive to upgrade. If your portable computer isn’t running as fast as it could, one of the simplest and cheapest ways to boost performance is to upgrade to more laptop memory.

To determine the correct type of RAM for your laptop, use our system checker located at our website here http://www.oempcworld.com/.

Most desktop computers offer four sockets for memory, and allow you to easily upgrade to as much as 4GB. However, laptop computers only usually have two memory sockets, and sometimes only one of those is available to the customer to add memory to without taking apart the entire laptop.

How much RAM does your laptop need? Much like desktop computers, the answer to this question depends more on the way you use your laptop. A laptop that is only used for business or schoolwork applications can see a noticeable benefit from upgrading to 1 gigabyte of laptop memory, from just 512k. If you plan to game on your laptop, or run graphically intensive applications like Photoshop, more memory will almost certainly help you run your programs more efficiently, and experience less slowdown.

What Types of Memory Stick Media are Available?cont....

The Memory Stick Micro was created to compete against the microSD standard. The two devices are almost exactly the same size, with the Micro being only a millimeter larger in total. While it is more expensive, it is also twice as fast as microSD memory, transferring data at 20MB/second as opposed to 10MB/sec.

So if you have a camera or other device that uses Memory Stick media, take a look at the memory selection utility below. Just enter the model of your product, and our system can tell you what type of memory you need for that device. Or if you already know, take a look at the Flash Memory section, where you'll be able to find what you are looking for.
