Windows 7: Readyboost issue

Readyboost issue

Hi there
Well, i've got a ReadyBoost problem.
I just bought a brand-new 32 GB Kingston Data Traveler Flash Drive, and it says that my device is not Suitable to Readyboost.
But the thing is, the very same 8 GB Kingston Data Traveler Flash Drive used to work just fine. What should i do?
I already tried to set Write-Caching, but it wouldn't change anything.

Help Please!

Thank you, Alex.

Hi AlexRD,

Try formatting the drive unplug then plug back in.
I formatted mine as ntfs.

Well, in mine it says i can't format it to NTFS, and i tried formatting and nothing is different.
Is yours the 32 GBs Version?

Thanks,
Alex.

Is this the Data Traveler 150 (and what variant)? If you don't know, just describe it or send us a pic, and we will see what we can dig up.

I have read some reviews on this drive and it seems it is a bit slow.
If that is the case then this will not work for readyboost.
You need a high speed drive.

Hi there.

Actually why would you need readyboost anyway?

Even with small amount of RAM I think the Jury is still out on whether Readyboot is actually any good - especially if your primary hard disk(s) are reasonably fast.

On a 64 bit build it could even theoretically make things worse as the OS paging algorithim would have to do more work -- the "Page fault" generated by the OS in searching for memory that's not in real RAM would have to determine WHICH device the required data was on and if it was on the USB device then create another "Interrupt" to handle I/O to that device (usally by an IRQ in the BIOS), pause any pending I/O's on your disks (unless you've got SCSI in which case Readyboost is a total waste of time), and move the data to RAM.

Meanwhile you might have had another "Page Fault" for the same application wanting a chunk of memory from the paging disks. - Everthing has to wait again for this to be moved to RAM to be available again.

Of course a lot of this stuff is "theoretical mathematics" based a lot on "probablity theory". The OS tries to maximize paging efficiency based on well known algorithms such as LRU and MRU ("Last recently used" and Most recently Used").

When your system isn't under load the computer will page some of these "segments" back into main RAM if it's available ready for a possible "future" request for those chunks of memory. Now if this stuff is residing on a slow USB device it could really hamper the speed of the OS.

I'd really avoid Readyboost if I were you especially on the later Windows build -- I've even got a 1GB RAM small 11 inch laptop running Windows 7 build 7077 X-64 and provided I don't go bonkers with running very much at the same time then it works just fine -- even photoshop CS4 (64 bit version) -- OK making multiple layers etc on a HUGE RAW file is a bit slow but I really shouldn't be using that piece of kit for such types of work.

For gaming you are unlikely to see ANY peformance whatsoever -- you need the best Graphics card you can get,a decent amount of RAM, and VERY IMPORTANT - FAST DISKS. -- I doubt that on most games whether you'd actually get much improvement by just "upping" the CPU to say a QUAD unless the other components where changed as well -- but a topic for another post.

Hoped you enjoyed the "Before Breakfast" introductory course on "OS Paging 101" - especially on a Saturday Morning.

Cheers

Well, nice "Before Breakfast" introductory course
But, the thing is that my HD is very slow. It runs on 4200 RPM, and its not only about the Readyboost. Its like, if my Flash Drive can't run the readyboost, then there must be a speed problem with it. So i don't want to find a problem in it one day after the warranty expires :P

Thats my Flash Drive ( Of course its 32GB , not 4 GB )

PS: How do i check my Flash Drive Speed?
PS²: Can i upgrade 7077 to 7100 version through Windows Update?


Thanks again for the Help,
Alex.

Crystal Disk Mark is easy. You can get your USB speed with the push of a few buttons.

And you cannot upgrade from 7077 to 7100 via WU. You must download the image, burn it, and perform a fresh install (no upgrading, you will have to lose all of your files, so back up what you need/want).

Incorrect

Build 7077 updates fine -- just run setup.exe from within Windows to do it (of course only X-86 ==> X-86 or x-64 to x-64).

You can however use the pop the CD in and navigate to setup.exe on it. That would work. However it is not reccomended you do so. We reccomend a clean install.
