ReadyBoost - high-speed cache

Everywhere and everywhere to scold and ridicule this operating system has become a good tradition. Meanwhile, Windows Vista is a good choice for an un-advanced user, because the user wants everything out of the box. Vista is just a “boxed” version, but it provides such tuning options, which other operating systems, it seems to me, have no idea.

Mobile RAM is now expensive, and where to put 512MB "chocolate" after the upgrade. Windows Vista users are lucky - cook flash drives. We are talking about ReadyBoost - an innovation Windows Vista, designed to increase system performance. With the help of new technology, users can use USB drives, flash cards of any formats supported by your card reader, as additional space for caching system files and application files.

Before using ReadyBoost, the operating system tests the device for compliance with some technical requirements, the test is as follows: 4 KB of random reads at a speed of 2.5 MB / s and 512 KB of random records at a speed of 1.75 MB / s, and there is a possibility that Vista will not approve the device, so you should “wean” ReadyBoost from testing.

Wean

So, we connect the device, go to "My Computer", click on our device with the right button, in the context menu we find the item "Properties". Next, in the ReadyBoost tab, we tick the “Stop device testing on connection” option, disable the device.

Go to the registry by typing in the Start - Run command “regedit” without quotes, find the HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows NT / CurrentVersion / EMDgmt branch, find the subfolder with the name of the device you need to allow ReadyBoost, and in this folder we change the values the following keys - Device Status = 2, ReadSpeedKBs = 1000 and WriteSpeedKBs also set the value to 1000. We connect the device, go to the properties, go to the ReadyBoost tab and select “Use this device”, and below the slider we set the volume, which is not a bad thing to spend on the cache. We are happy.

FAQ:

Operating principle. In short, ReadyBoost is the use of Flash memory to speed up the loading of OS and applications due to a much shorter access time when reading, and writing data to such memory. ReadyBoost does not require high speeds, much more important is the microscopic access time to flash memory, which is sometimes 10 times less than that of the HDD.

Performance. When reading 4kb blocks, the performance gain is up to 10 times compared to HDD, but when reading large files, the effect is lost. However, ReadyBoost is used just when downloading applications, when there are multiple calls to dozens of small libraries and the gain is often noticeable.

Security. ReadyBoost is nothing more than a cache, it makes a backup of the swap on the HDD, so that you can remove the flash drive at any time and not lose data. All data is encrypted using the AES-128 algorithm.

Minimum. ReadyBoost can use 256 megabytes (250 after formatting)

Maximum. ReadyBoost can use up to 4GB of physical flash memory, which corresponds to approximately 8GB of data during compression. FAT32 is used to support small-size memory cards, and the limitation of this file system is 4GB.

Wear resistance. The flash drive will stretch in this mode, according to preliminary test results, for more than ten years.

Limitations. Unable to use two flash drives. External USB 2.0 HDD will not work. It is undesirable to use an external card reader, in this case delays increase. It is undesirable to use the MP3 player - Many players work on a clever algorithm, and this again increases the delay.

Couple of tips

The advantage of SD cards is that they fit in the slot and become invisible until you pull them out. This is a small aesthetic aspect. Of course, there are laptop models where the reader does not fully accept the card.

You can try to turn off the data sweeping, because the sweeping requires the processing power of the processor, and it is worth its gold.
