If you're trying to access the hard drive while it's writing to the swap file, the computer drags ass and is virtually unusable.
#What is readyboost on my usb windows
Although readyboost tries to read from flash, Windows is still writing the swap file to the hard drive as well as the flash. Now double click on that file and change the Value Data from 0 to 1000 and then press OK.Many of us have found out the hard way that readyboost doesn't actually do anything to improve performance. Right click on the blank space in that selected USBfolder and click on QWORD (64 bit) Value and after that right click to rename the value to SpeedReadKBs and press enter. This step might not be required, depending on your device. Step 7:ĭouble click on DeviceStatus, and modify the value date to 2. Step 6:ĭouble click on WriteSpeedKBs and change its value data to 1000 (Decimal) or anything larger than that. This would be a USB whose test that failed. Did you fail to identify your flash drive from this extensive list? Then try to find a product which has a value 4 at DeviceStatus. Near the beginning of this long line we notice the Verbatim brand and that helps us identify which USB flash drive we want to enable ReadyBoost on. The registry editor, on this particular key includes all USB drives you ever connected on your computer.Īs you see in the image, all the USB drives that have been detected in the past are shown here – each line is a flash drive, and the pattern goes like this: Navigate to the following registry entry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt Select ReadyBoost tab and tick the box that says Do Not Retest This Device.

You will accomplish it by “tricking” the operating system into thinking the device is fast enough.ĭisclaimer: This article will guide you into editing a Windows Registry entry.
We will describe a work-around that will allow you to enable ReadyBoost for your device. Even if you have a device that is not supported. This is where this guide might be helpful for you. So, you might ask – what happens if I only have one flash drive to spare because I do not want to use my brand new device in ReadyBoost? Is there a way to force enable Readyboost? Should have at least a 1.75 MB/sec throughput for 1 MB random writes.Īs you understand, older and over-used devices often cannot meet these requirements, especially on the issue of read and write speeds – essentially, a USB flash drive does have a limit of read and writes in its life, after which its performance significantly deteriorates.Should have abilities of at least a 2.5 MB/sec throughput for 4 KB random reads.It should have an access time of 1 ms or less.
