USB Flash Drives will Boost Your System Performance. |

Adding system memory (RAM) is often the best way to improve your PC's performance. More memory means applications can run without needing to access the hard drive. However, upgrading memory is not always easy. You need to know what type of memory you need, purchase the memory, and open your computer to install the memory--which sometimes can invalidate your support agreement. Also, some machines have limited memory expansion capabilities, preventing you from adding RAM even if you are willing to do so.
Windows ReadyBoost™ (formerly code-named "EMD") makes PCs running genuine Windows Vista more responsive by using flash memory on a USB drive, SD Card, Compact Flash, or other memory form factor to boost system performance. Windows ReadyBoost can improve system performance because it can retrieve data kept on the flash memory more quickly than it can retrieve data kept on the hard disk, decreasing the time you need to wait for your PC to respond. Combined with SuperFetch technology, this can help drive impressive improvements in system responsiveness.
Using ReadyBoost-capable flash memory devices for caching allows Windows Vista to service random disk reads with performance that is typically 8-10 times faster than random reads from traditional hard drives. This caching is applied to all disk content, not just the page file or system DLLs.
Of course, most flash devices are slower than the hard drive for sequential I/O. To maximize performance, ReadyBoost will include logic to recognize large, sequential read requests and then allows these requests to be serviced by the hard drive. But more importantly, ReadyBoost will cut down on drive usage, which will improve the power performance when running on battery power.
After some period of usage, the flash device will likely contain sensitive information. The data on the external flash drive will be automatically encrypted using AES (Advanced Encryption Standard) 128, just in case you misplace the dongle. ReadyBoost encrypts the content for use only on the PC system where the data was generated.
Windows ReadyBoost technology is reliable and provides protection of the data stored on your device. You can remove the memory device at any time without any loss of data or negative impact to the system; however, if you remove the device, your performance returns to the level you experienced without the device. Additionally, data on the removable memory device is encrypted to help prevent inappropriate access to data when the device is removed.
Here are the baseline requirements of the USB Drive/Flash Drive, regarding what ReadyBoost will work with:
* The USB Key must be at least USB 2.0
* The device must be able to do 3.5 MB/s for 4 KB random reads uniformly across the entire device and 2.5 MB/s for 512 KB random writes uniformly across the device.
* The USB Key has to have at least 64mb of free space
