Trick to Use Any USB Key or Flash Drive to Ready Boost Vista帽子戏法使用任何USB钥匙或闪存驱动器，以提高Vista的准备

ReadyBoost is a ReadyBoost的是一个 new feature新功能 that first included in Windows Vista with the aim to speed up Vista performance.首先包括在Windows Vista的目标，加快Vista的性能。 ReadyBoost is actually an ReadyBoost的实际上是一个 disk caching technology that uses flash memory磁盘高速缓存技术，利用快闪记忆体 on a USB 2.0 drive, Secure Digital (SD), CompactFlash (CF), Memory Stick, MMC card, or other form of USB flash memory, USB flash drive or USB key, as extra virtual memory in order to boost system performance and make system more responsive.上一个USB 2.0驱动器，安全数字（ SD ） ，的CompactFlash闪存卡（ CF ） ，记忆棒， MMC卡，或其他形式的USB闪存， USB闪存驱动器或USB关键，因为额外的虚拟内存以提升系统性能，而且使系统更加敏感。 The theory is that flash drive which has no mechanical part, has a much faster seek time (less than 1 millisecond), thus will be able to service random disk reads requests for certain system files faster then hard disk.该理论是，闪存驱动器，没有机械部分，有一个更快的寻道时间（小于1毫秒） ，从而将能够服务随机磁盘读取请求的某些系统文件然后更快的硬盘。 Beside, ReadyBoost also leverages the inherent parallelism of having two sources to read data from.旁边，还充分利用的ReadyBoost所固有的并行性有两个来源，从读取数据。

Although the actual performance increase by using ReadyBoost is minimal, you may still want to try to activate ReadyBoost to see if it helps and boosts your system speed or not.虽然实际性能提升使用ReadyBoost的是最小的，您可能仍想尝试启用ReadyBoost的，看它是否有助于并提高您的系统速度或没有。 However, not all flash device are compatible and can be used to Ready Boost.然而，并不是所有的闪存设备兼容，可用于升压准备。 In order to use an USB key flash memory with ReadyBoost, it must meet at least the following specification requirements of ReadyBoost-capable flash memory (NAND memory devices):为了使用一个USB密钥闪存ReadyBoost的，它必须至少满足以下规格要求的ReadyBoost功能的快闪记忆体（ NAND记忆体装置） ：

1. The capacity of the removable media must be at least 256 MB (or 250 MB after formatting).的能力可移动媒体必须至少使用256 MB （或250甲基溴后格式化） 。
2. ReadyBoost will only utilize maximum of 4 GB flash memory. ReadyBoost的将只使用最高4 GB的快闪记忆体。 The ReadyBoost.sfcache file size is also limited by FAT32 filesystem to 4GB.该ReadyBoost.sfcache文件的大小也很有限了FAT32的文件到4GB 。
3. The flash devices must be capable of 2.5MB/sec throughput for 4K random reads spread uniformly across the entire device.该闪存设备必须能够2.5MB/sec吞吐量的4K随机读取均匀分布在整个设备。
4. The flash memory must also be capable of 1.75MB/sec throughput for 512K random writes spread uniformly across the device.在快闪记忆体还必须能够1.75MB/sec吞吐量为512K随机写入均匀分布整个装置。
5. The device should have an access time of 1ms or less.该设备应该有一个访问时间1ms或更少。
6. Sequential performance of the flash is not measured.时序性能的闪存不是衡量。
7. The device must have at least 235 MB of free space.该装置必须至少有235 MB的可用空间。
8. Both NTFS and FAT32 filesystem are supported.双方的NTFS和FAT32文件系统的支持。
9. ReadyBoost supports one flash device at any time as of currently. ReadyBoost的支持一个闪存设备在任何时间截至目前。
