Remember the famous law of Moore? Of course, the past years have proved its actual inconsistency, but the power of the computer equipment we use is actually increasing at a very fast pace.
Unfortunately, not all of us keep pace with progress. Someone "at the service" continues to have old computers, whose power is already far from as significant as we would like. ReadyBoost can somewhat fix the situation. What it is? It is the consideration of this issue that our article is devoted to.Basic information

Many users at one time were “burned” precisely because the flash drive was necessary for the full-fledged operation of this option. Simply put, the device should have decent speed, so the USB whistle bought in the nearest stall will probably not pull.The minimum read speed is from 2.5 Mb / s, in blocks of 4 kb. At a speed of 1.75 Mb / s, the device should be able to write blocks of 512 kb. The minimum amount of free space on a removable disk is at least 256 MB. Manufacturers recommend correlating the recommended drive size based on a simple 1: 1 formula. Simply put, 1 GB of RAM should equal the size of a flash drive using ReadyBoost technology.

To do this, you must specify the amount of disk space that will be used to speed up the system. Click on the "OK" button. Next, the system automatically configures the cache. Depending on the characteristics of the device, this process takes from 10 to 15 seconds. After that, the system connects the prepared device to work. The success indicator of all your actions is just the ReadyBoost.sfcache file, which must appear on the disk used.
Remember to disable ReadyBoost correctly. What does it mean?
Proper technology shutdown
The removable disk that you use for these purposes must be connected to the computer. Again, right-click on the desired removable disk, and then select the "Properties" item in the context menu. Select the ReadyBoost tab.
Before removing ReadyBoost from a USB flash drive, select the "Do not use this device" option. Click OK. Attention! In some cases, after disabling the option, the device displays a warning about a data reading error. In this case, you need to click on the "Test device" button, which is in the dialog box that appears. As a rule, the system automatically corrects all available errors, after which the disk can again be used to store data.
Since deleting ReadyBoost from a USB flash drive in this way is rather tedious, many prefer to simply erase the disk cache file, as a result of which they often encounter numerous errors in the system. Do not do that!Windows says drive cannot use Ready Boost

It is there that all the parameters that are responsible for the ability to use a flash drive as RAM are stored. In particular, CacheSizeInMB shows how much disk space the option can "bite" under the cache. If you plan to use a 2 GB flash drive, then you should write the value 2048 in this field. Set CacheStatus to 1. In the DeviceStatus field, enter 2.
In DoRetestDevice, you must specify the value 0, since this parameter is responsible for testing the speed performance of the disk (by default, it starts every time it is connected). This is especially important when it comes to ReadyBoost in Windows 7, since in Windows Vista the requirements for the speed of the drive used are not so strict.ReadSpeedKBs WriteSpeedKBs – . , ReadyBoost. 3600 ReadSpeedKBs, WriteSpeedKBs 2500. !

Important: despite the modifications you made in the registry, the real characteristics of your removable disk have not changed. Roughly speaking, what a slow flash drive it was, it remained that way, since miracles do not happen. Do not count on real acceleration of the system.
Therefore, do not use drives that are too slow, because the effect of them will be exactly the opposite: the speed of the OS due to Windows ReadyBoost will slow down, and you will be wondering where the resources go.Is it possible to use a removable hard drive as a flash drive?
To answer this question, click on the device icon, and then select “Properties”. If the ReadyBoost option is active in it, then you can connect it.
