ReadyBoost to increase performance weak of Windows devices through USB drives and SD cards

One of the budget ways increase performance Windows computer is the application software ReadyBoost technology from Microsoft that allows you to use the resources flash drives – flash drives and SD cards to expand your virtual RAM. You can even buy specially for this purpose a separate USB flash drive, its price is unlikely to hit the budget, unlike the RAM or SSD. The application ReadyBoost in fact there are many «buts» and the real performance gains will be felt not in each case.

Below is a look at how the technology is ReadyBoost, how to use Windows operating system, in some cases, it will be a sense.

How does the technology ReadyBoost

Windows operating system uses hard disk space to extend RAM – physical RAM by using a swap file, where the data moves the system cache. Thereby freeing up RAM for new tasks. The paging file together with RAM are virtual memory. ReadyBoost does not replace the specific use of the system paging file, but is able to remove the load from the hard drive, so that in the course of its work, not distracted by access to the file system cache.

The system cache is a set of small files, which classic hard drives with magnetic platters read slowly. Latest your speed potential like showing sequential reads of large files. For random reading of files with a small weight the speed of conventional hard drive is negligible. But with flash drives and SD cards, the situation is reversed: giving a speed many times less than the hard drive, when reading large files, the flash drives are seriously beat classic HDD in random reads of small files.

Clearly this picture illustrates the test results of a conventional hard drive and flash drive using CrystalDiskMark. Field «Seq» is the speed of sequential reading and writing that media can give when working with large files. The value field of the «4K QD32» is the random read speed and write block size of 4 KB, that is, small files. As you can see, sequential read speed of large files of the hard drive is 172,4 MB/s, whereas USB drive (with interface connecting USB 3.0) only 26,24 MB/s When reading small files from pendrive speed more: 4,33 MB/s vs. 0.69 Mbps speed hard drive.

The lack of memory and low hard disk speed when accessing data, the system cache in most cases, the root cause of the brakes and hang, low-power PCs and laptops. The essence of ReadyBoost is to provide Windows separate place on your hard drive, and other storage media for storing the cache data in some cases can give a performance boost up to 30%.

Requirements for the flash drive

To use ReadyBoost read speed flash drive small files should not be less than 2.5 MB/s And its volume must be either the same as the amount of available RAM or more. To capitalize on the resource flash drive with a volume of more than 4 GB, you must format it with the NTFS file system. Because FAT32 simply will not see files larger than 4 GB.

The flash drive can, but should not be completely given over to the use of ReadyBoost. If it will be used not the entire volume stick or SD card, they can be stored some data, which will not interfere with the working cache file ReadyBoost.

Not necessarily, but it is advisable to use a pendrive with the new interface USB 3.0 connectivity. And connect the flash drive to a better USB output, located directly on the motherboard.

Not all USB flash drives and SD memory cards are compatible with ReadyBoost, but most of them.

How to use ReadyBoost in Windows

The ReadyBoost can be used in all versions of Windows starting with Vista. If a system service called SuperFetch before it was intentionally disabled, you must turn it back.

To enable ReadyBoost in Windows Explorer select the drive connected the flash drive context menu and choose «Properties».

In the properties window, switch to the tab «ReadyBoost».

Next, make active the option «Use this device». In the field specify the size of the allocated space for ReadyBoost, the system defaults the entire free volume of the flash drive. This size can be reduced by pulling the slider to specify the desired numbers if further provides for the use of memory stick or SD card for data storage. In our case, ReadyBoost will try to get the maximum performance and deliver the technology the entire volume stick. Click «Apply».

This will be followed by setting up the system cache, and the flash drive will be working on the file ReadyBoost.

Disabling ReadyBoost

If you need the entire volume of the flash drive for storage of data, ReadyBoost can be disabled, returning the settings of the tabs in the properties of the USB drive or SD card to its original state.

For temporary disconnection of the flash drive when it is enough to use ReadyBoost safely remove hardware.

Can ReadyBoost to replace the paging file?

Completely replace the ReadyBoost paging file can only be in the individual case. If you have a computer with 4 GB of RAM, if you have a high speed USB flash drive with interface USB 3.0 connectivity and a volume of 8 GB, which is fully reserved for ReadyBoost, pagefile can be disabled.

Therefore, the hard disk will be reduced to the maximum, and the freed-up resources will be entirely involved to solve other tasks. If performance and RAM capacity on a flash storage device is less unlikely to experiment with disabling the swap file.

In some cases, ReadyBoost will be effective?

The effect of the application of this technology will be difficult to feel on modern computers with 4 GB of RAM. Is that with the above example of engaging high-speed flash media, and disable paging file. A small increase in performance can be noticeable on laptops with 2 GB RAM and conventional hard drive. On devices with SSD in this function makes no sense, because the speed of reading small files, the SSD is superior to speed of flash drives and SD memory cards. Moreover, on devices with SSD Windows usually disables itself is the ReadyBoost technology to someone old memory made his worst working conditions with the computer.

The performance increase will be felt only on older builds PCs and netbooks with low power RAM up to 2 GB. ReadyBoost can be used when working with the hypervisor, if the RAM does not allow you to share virtual machines with more than 1GB.

For low-power computing devices ReadyBoost can be a temporary some performance improvements. For example, to accumulate the amount needed to upgrade the computer or until the expiration of the warranty period, if indispensable technical sales is an intact seal on the housing. If you disable the paging file altogether, you will need every time to restart the system to turn on if the USB flash drive or SD card will be needed for other purposes. Without virtual memory computer with 4 GB of RAM will keep getting messages about insufficient resources.

ReadyBoost performance is superior to the use of the paging file on conventional hard disk, but not up to the capabilities of the RAM and does not negate the need for the increase. The real increase computer speed in most cases

can only provide replacement of hardware components at present or more productive.
