Windows 10 ReadyBoost enable on USB flash drive, missing ReadyBoost tab, SSD

User question

how to enable ReadyBoost on Windows 10

Artificial Intelligence Response

Direct answer to the question

To enable ReadyBoost on Windows 10:

1. Insert a USB flash drive or SD card.
2. Open File Explorer and go to This PC.
3. Right-click the removable drive and select Properties.
4. Open the ReadyBoost tab.
5. Choose either:
   • Dedicate this device to ReadyBoost, or
   • Use this device and set how much space to reserve.
6. Click Apply and OK.

If the ReadyBoost tab is missing or disabled, the usual reasons are:

• the drive is too slow,
• SysMain is disabled,
• or your PC uses an SSD, in which case Windows often disables ReadyBoost because it provides little or no benefit.

Detailed problem analysis

What ReadyBoost actually does

ReadyBoost is a Windows caching feature that uses flash storage as an auxiliary cache to reduce some disk-access delays. It was mainly designed for older PCs with:

• a mechanical hard drive (HDD),
• low RAM,
• and generally slower storage performance.

It is not a RAM upgrade. It does not replace physical memory. It only provides a cache layer that may improve responsiveness in certain HDD-based systems.

When ReadyBoost is worth using

ReadyBoost is most useful if your system has:

• an HDD instead of an SSD,
• 2 GB to 4 GB of RAM or similarly limited memory,
• frequent disk activity and paging.

It is usually not worth using if your system has:

• an SSD or NVMe drive,
• plenty of RAM,
• already good storage performance.

On SSD-based systems, Windows may show a message similar to “This computer is fast enough” or may not allow ReadyBoost at all.

Supporting explanations and details

Step-by-step procedure

1. Check that SysMain is enabled

ReadyBoost depends on the SysMain service.

To verify it:

1. Press Win + R
2. Type services.msc
3. Press Enter
4. Find SysMain
5. Open it and make sure:
   • Startup type is set to Automatic
   • service status is Running

If it is stopped, click Start.

2. Prepare the USB drive or SD card

Use a reasonably fast flash device.

Practical recommendations:

• At least 1 GB free space
• Prefer USB 3.0 media if your PC supports it
• Format as NTFS or exFAT if needed

If you format the device:

1. Right-click the drive in This PC
2. Select Format
3. Choose NTFS or exFAT
4. Start formatting

Important: formatting erases all files on that device.

3. Enable ReadyBoost

After inserting the drive:

1. Open File Explorer
2. Go to This PC
3. Right-click the removable drive
4. Select Properties
5. Open the ReadyBoost tab
6. Select one of the following:
   • Do not use this device
   • Dedicate this device to ReadyBoost
   • Use this device
7. If you choose Use this device, adjust the reserved cache size
8. Click Apply, then OK

Windows will create its ReadyBoost cache file automatically.

Current information and trends

ReadyBoost still exists in Windows 10, but in modern systems it is much less relevant than it was in the Windows Vista and Windows 7 era.

Current practical reality:

• On modern SSD-based PCs, ReadyBoost is usually unnecessary.
• On older HDD-based laptops or desktops, it can still offer a small improvement.
• In most cases, a real RAM upgrade or replacing the HDD with an SSD gives vastly better results.

So yes, you can enable it on Windows 10 if the hardware qualifies, but it is now a niche optimization rather than a primary performance solution.

Practical guidelines

If the ReadyBoost tab is missing or grayed out

Check the following:

• Drive too slow
  Windows tests removable media automatically. If it fails, ReadyBoost cannot be enabled.

• SysMain disabled
  Re-enable it in services.msc.

• SSD system drive
  Windows may intentionally block ReadyBoost.

• Unsupported or poor-quality flash device
  Try a different USB drive, preferably a faster one.

• Drive formatting issue
  Reformat as NTFS or exFAT if appropriate.

---

Best practices

• Use a dedicated flash drive if possible.
• Avoid very old or very cheap USB drives.
• Connect the device directly to the PC rather than through an unreliable hub.
• Do not expect dramatic performance gains.

---

Recommended alternatives

If your PC feels slow, these upgrades are far more effective than ReadyBoost:

1. Replace HDD with SSD

   • biggest improvement in boot and application load times

2. Increase RAM

   • most effective if the system is memory-constrained

3. Reduce startup programs

   • helps responsiveness without hardware changes

4. Check disk health

   • a failing HDD can make the system slow regardless of ReadyBoost

---

Possible disclaimers or additional notes

• There are registry-based methods online that claim to force-enable ReadyBoost on unsupported systems.
• These methods are not officially recommended and usually provide little benefit, especially on SSD systems.
• If Windows says the PC is already fast enough, forcing ReadyBoost is generally not a sound engineering choice.

Brief summary

To enable ReadyBoost on Windows 10, insert a compatible USB or SD device, open its Properties, go to the ReadyBoost tab, and select Use this device or Dedicate this device to ReadyBoost.

The feature is mainly useful on older HDD-based computers with limited RAM. If your PC uses an SSD, Windows may disable ReadyBoost because it is usually ineffective. For meaningful performance improvement, SSD and RAM upgrades are much better solutions.

If you want, I can also give you:

1. a troubleshooting checklist for when the ReadyBoost tab does not appear, or
2. a quick way to tell whether your PC has an HDD or SSD.
