If you have own a Google Nexus One then you probably enjoy watching video and listening to audio on it. You may even download files to your phone or carry work documents on it. All of that requires memory. The Google Nexus One uses mini-SD memory cards. Most Google Nexus One phones come with one 4GB memory card. Most of these phones will accept mini-SD memory cards that are larger than 4GB, but you should consult the documentation for your phone to determine the specifications. Often there is a significant range, but that does not mean that you need that size disk.
Consider this:
Size
Size is essential for uses. When it comes to the memory cards that you use with your Google Nexus One you will have options. If you intend to store a single file that is larger than 4GB then you will likely have to purchase a larger capacity disk. In some cases you may benefit from other choices.
If you have multiple tasks that you use your storage for you may want to opt for multiple smaller disks. For example, if you store movies to watch or photos to share you may want one disk for that use. For work and other uses you may want to purchase another disk.
It is vital to have the amount of storage that you need, and in most cases there is no extreme difficulty in storing files from work and personal life on the same card. For some purposes though having separate cards can provide real benefits.
Cost
If you are considering purchasing multiple memory cards for your Google Nexus One you may be interested to know what the pricing is like. At the time this was written two 4GB memory cards for the Google Nexus One could be found for approximately the same price as one 8GB memory card. These prices were from the same online retailer. Both options were under thirty dollars (US).
Another consideration is that with each increase you see approximately the same level of increase. For instance 16GB memory cards for the Google Nexus One were found at approximately twice the price of the 8GB memory cards. There are some ways to secure considerable savings though.
Looking for sales and discounts at the retailers that you consider can be effective. Similarly you may notice large differences in the prices of similar memory cards made by different manufacturers. By selecting the brand of disk carefully you can get quality and savings in your memory cards.
Adapters
You probably already realize that the memory slot in your computer or other device may be different than the memory slot in your Google Nexus One. There are options to create compatibility though. A number of cards come with mini to standard adapters. If yours did not there are some available for sale individually. You may likely want to consider that when comparing costs.
Similarly if you do not have an SD slot of any kind on your other devices there are mini-SD to USB adapters available. These allow you to access data on a mini-SD card using a USB port.
