ReadyBoost is also used to facilitate SuperFetch, which allows it to. It works by using flash memory, a USB flash drive, SD card, CompactFlash, external hard drive or any kind of portable flash mass storage system as a drive for disk cache. This can be beneficial to other community members reading the thread. ReadyBoost (codenamed EMD) is a component of Microsoft Windows, first introduced with Microsoft's Windows Vista in 2006 and bundled with Windows 7 in 2009.

In addition, USB 3.0 and Firewire may also hold a slight advantage on sequential data. So, all USB 2.0 and newer flash drives hold an advantage in random access times: typicallyĪround 1 ms, compared to 8 ms and upwards for desktop hard drives. Then, we need to go to file explorer (My computer / This PC) where all the drives are. Sustain anywhere from 2 to 10 times the transfer speed of USB 2.0 flash drives but are equal to or slower than USB 3.0 and Firewire (IEEE 1394) for sequential data. The first thing to do is to insert a flash drive / USB Stick. Unfortunately, USB 2.0 flash drives are slower for sequential reads and writes, compared to modern desktop hard drives. It also leverages the inherent advantage of two parallel sources from which to read data. The core idea of ReadyBoost is that a flash drive has a much faster seek time (less than 1 ms), allowing it to satisfy requests faster than readingįiles from a hard disk. Then, right click Properties on your USB key and go to. 'ReadyBoost' was an option in the device properties, and. To enable and use ReadyBoost, plug your USB key in your computer and go to the start menu -> computer. Windows 7 supports the new exFAT file system which can be under consideration. I understand it's supposed to be possible to use an SSD as a ReadyBoost device instead of a USB stick (note that I'm not suggesting using ReadyBoost to cache a SSD I'm suggesting using an SSD to hold the ReadyBoost cache). So the issue simply become which USB is the fastest. ReadyBoost is smart enough to just let the system read large, sequential blocks of data directly from the hard drive to save time. Microsoft recommends the amount of flash memory for ReadyBoost acceleration be one to three times the amount of random access memory (RAM) in your computer.
