This disk caching is beneficial in case the system is running a slow hard drive. ReadyBoost is a feature that speeds up Windows by storing application files and data as cache in a USB drive. Because ReadyBoost stores its cache as a file rather than directly using the flash device in a raw manner, that file system must be mounted and assigned a drive letter.

Windows 7 supports multiple flash drives for ReadyBoost. ReadyBoost is a special disk cache service in Windows Vista, 7, 8, 8.1 and 10 that uses fast removable devices, such as USB flash drives, Secure Digital and CompactFlash memory cards for speeding up smaller random disk reads.Ī file with the SFCACHE file extension is a ReadyBoost Cache file that’s created on a compatible USB device, like a flash drive or SD card, that Windows is using for extra memory. The initial release of ReadyBoost for Windows Vista supports one device. The data, that is contained on a flash drive should not be deleted or corrupted when you start using the device for ReadyBoost. You can adjust how much space on your flash memory device may be dedicated to ReadyBoost and store your data in unused space. But in recent times, the technology is used to cache the frequent files to the removable discs like memory cards, flash drives, or other external storages.

ReadyBoost in Windows 10 allows you to use your flash memory devices to speed up you computer. What Is Readyboost So, what do you understand about the term Readyboost When the technology was invented, the flash USB-drives could offer faster ways to transfer files from RAM. In order to do that, user should enter its properties and the ReadyBoost tab and choose the use this device option. SFCACHE can be enabled on a chosen flash disc.

The ReadyBoost function creates temporary cache memory files ReadyBoost.

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 computer. As the ReadyBoost cache is stored as a file, the flash drive must be formatted as FAT32, NTFS, or exFAT in order to have a cache size greater than FAT16s 2 GB filesize limit if the desired cache size is 4 GB (the FAT32 filesize limit) or larger, the drive must be formatted as NTFS or exFAT. and associated with the ReadyBoost Cache File format as it's. All files in the cache are encrypted using 128-bit AES if the flash storage device is removable, but hardware manufacturers can choose to disable encryption on internal, non-removable.

The newly inserted memory serves as additional cache location for RAM or memory which the computer can access faster then a system hard drive. Most SFCACHE files can be viewed with two known software applications, typically Microsoft Windows developed by Microsoft Corporation. SuperFetch monitors files that users access (including system files, application files, and documents) and preloads those files into the ReadyBoost cache.

On Windows 7, the largest cache file size is 256GB (can span up to 8 flash drives). USB Readyboost allows increased PC performance without having to install additional memory on the motherboard, but rather externally via USB port. We gathered the information while the PCMark Vantage 圆4 benchmark was running, because its a complete test that runs for a few hours, so there is enough time to see ReadyBoost in action. On Windows Vista, the largest cache file size is 4GB We have set up a Data Collector Set for the ReadyBoost cache counters.

The device must have at least 235MB 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 512KB random writes spread uniformly across the device The capacity of the USB flash drive must be at least 256MB (250 after formatting). The device should have an access time of 1 ms or less. This allows Windows Vista or Windows 7 to service random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives.įor a USB flash drive to be compatible, it must conform to the following requirements: ReadyBoost is a feature of Windows Vista and Windows 7 that uses a USB flash drive for caching.
