How to enable Readyboost that is disabled in error

I have 3 32BG RB USB 3 drives on a desktop with 64GB.. the claim it doesn't help when a system has 4 GB or more ram is GARBAGE. They STILL help... that gives me almost 128GB of cache - which I DO actually need. I've seen them GREATLY speed up system with 8,16,and32 GB RAM because the HD system is SLOW.

Granted a FAST raid 0 or raid 5 array MIGHT be able to match a use 3 thumb drive.. but usb 3 drives can now perform operations at 300-400MegaBYTES per second which is faster than most raid 0 arrays unless u have 5 or 6 sata 3 drives in that array

I've seen PLENTY of SSD drives that don't even come CLOSE to the speed of a usb3 thumb drive.. why? Thumb drives are SMALL.. they can put in FAST storage for low price becuase it's not much... but a SSD that can read and write in the 300-500MegaBYTE range will cost u an arm and a leg

my point is that is NOT up to MS to AUTO disable it.. LEAVE IT TO THE USER to decide on their own.. let the USER test it and then they can ignore all the forum opinion and the banter over it all..

Just. Let. The. User. Decide.

i have hp mini 1000 (1154nr 2 gb ram 120gb ssd)get message when inserting any usb drive that readyboost not available computer fast enough (kinda p-ist)

i suggest that readyboost be rebranded maybeboost or ifyameetmsrequiremntboost anybody know regkey or syskey to force enable

happy holidays

I was tweaking a bit more and this may be of interest to potential readyboost users with a system SSD installed.

Hatsoffsec has figured out the key to turning readyboost back on at his webpage:

I had success turning ReadyBoost on...even with an SSD as the main system disk.

I actually went a step further in my T500 with an EVO 850 SSD running the Samsung Rapidmode with 8GB of RAM.   Rapidmode with the EVO SSD is much faster than a HDD but with readyboost enabled on a RAMDISK drive my windows 7 system is that much more responsive.  I think it works so well because the T500 is still running SATA 2 on the mainboard.

This is what I did:

1. Install Dataram Ramdisk ( I was using V4_4_0_RC34). I also use Softperfects Ramdisk but it does not work with the Readyboost feature.
2. Set up a ramdisk size based on your installed ram.  I only used a small 260MB ramdisk size and stayed with the default FAT format.  Even a small readyboost cache of 260MB gives noticeably snappier performance and does not take up much system RAM.   I also recommended ticking the option the label the device as it will be easier to find in the next step.

3. Open Regedit and go to:   HKLM (Local Machine)->SOFTWARE->Microsoft->Windows NT->CurrentVersion->EMDgmt.  Find your device and left click on it( it should be labelled RAMDISK). In the right hand pane of regedit, double click "device status" and set it to 2. 

4. Also in Regedit, go to:   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\rdyboost\AttachState.  In the right hand panel, I set all the variable values to "0".
5. Open services.msc and set Superfetch to automatic and start it.
6. Open "my Computer" and right click the Ramdisk drive you created and select Properties.
7. Select the Readyboost drive tab and set it to "Use this disk"  or "dedicate this device".  I dedicated the entire 260MB to Readyboost with good results. 

I also enabled readyboost on a T61 with 6GB of ram with windows 7 and got the exact same performance boost as the T500 machine.  The t61 is running an 840 EVO SSD as the system disk and it has been modified with the Middleton BIOS so it is also running at SATA II speed.     However, rapidmode chews up too many cpu cycles and RAM so I keep it off for this laptop.  

I may even turn off rapidmode on my T500 thinkpad as the T61 with readyboost and the 500GB 840EVO is every bit as fast as the T500 with a 256GB 850 EVO with rapidmode and readyboost enabled.  It would appear that any SSD throttled by SATA 2 could benefit from this readyboost trick. 

Thanks to Hatsoffsec!

No Gordon, You misunderstand the use of Readyboost - Readyboost is not designed to compensate for the lack of RAM, but to enhance slow HDD performance.

"Use ReadyBoost to have more RAM" is a marketing ad.
