The core idea of ReadyBoost is that a flash drive has a much faster seek time (less than 1 millisecond), allowing it to satisfy the requests fairly quickly compared to a hard drive when booting or reading certain system files. ] In one test case, ReadyBoost sped up an operation from 11.7 seconds to 2 seconds (increasing physical memory from 512 MB to 1 GB reduced it to 0.8 seconds).

]Ī system with 512 MB of RAM (the minimum for Windows Vista) can see significant gains from ReadyBoost. Enabling write caching on the flash drive by selecting "Optimize for performance" in Device Manager will allow formatting as NTFS. * The recommended amount of flash memory to use for Windows ReadyBoost acceleration is one to three times the amount of random access memory (RAM) installed in your computerĭepending on the brand, wear and tear due to read-write cycles, and size of the flash memory, the ability to format as NTFS may not be available. * The initial release of ReadyBoost supports one device

* The device must have at least 235 MB of free space * The device must be capable of 2.5 MB/s read speeds for 4 KB random reads spread uniformly across the entire device and 1.75 MB/s write speeds for 512 KB random writes spread uniformly across the device

* The device should have an access time of 1 ms or less * Devices larger than 4 GB will have only 4 GB used for ReadyBoost * The capacity of the removable media must be at least 256 MB (250 after formatting) cite webįor a device to be compatible and useful it must conform to the following requirements: Title=Inside the Windows Vista Kernel: Part 2Īccording to Jim Allchin, for future releases of Windows, ReadyBoost will be able to use spare RAM on other networked Windows Vista PCs. ReadyBoost encrypts, with AES-128, and compresses all data that is placed on the flash device Microsoft has stated that a 2:1 compression ratio is typical, so that a 4 GB cache could contain upwards of 8 GB of data. Publisher=Microsoft] 250 MB to 4 GB of flash memory can be assigned. Title=ReadyBoost - Using Your USB Key to Speed Up Windows Vista When a compatible device is plugged in, the Windows AutoPlay dialog offers an additional option to use the flash drive to speed up the system an additional "ReadyBoost" tab is added to the drive's properties dialog where the amount of space to be used can be configured. cite web|url= |title=ReadyBoost Q&A |accessdate= |last=Archer |first=Tom |coauthors=Ayers, Matt |date= |work=Tom Archer's Blog |publisher= MSDN Blogs]

Flash devices are typically slower than the hard drive for sequential I/O, so to maximize performance, ReadyBoost includes logic to recognize large, sequential read requests and then allows these requests to be serviced by the hard drive. This caching is applied to all disk content, not just the page file or system DLLs. Using ReadyBoost-capable flash memory (NAND memory devices) for caching allows Windows Vista to service random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives. ReadyBoost is also used to facilitate SuperFetch, an updated version of Windows XP's prefetcher which performs analysis of boot-time disk usage patterns and creates a cache which is used in subsequent system boots.

It works by using flash memory, USB 2.0 drive, SD card, CompactFlash or any kind of portable massive flash storage as a drive for disk cache. ReadyBoost is an operating system feature included with Microsoft's Windows Vista operating system.
