Is my 256mb thumb drive making a difference to my 1gb installed ddr2
pc2-4200, athlon 64 live 4200 dual core system?

Probably not. Not only is is a small drive, it may be a slow drive. I know
you can force a 256MB to run ReadyBoost, but I'm not sure if it does it by
default.

Also, it depends on what you are doing. Web, email, word processing...
Probably not, with the 1GB of RAM.

Readyboost is a useful feature where a system can cache to a space faster
than anything a 10ms HDD can provide, while preserving RAM allocation for
where it would be better served.. while you may not notice huge gains, your
system will undoubtedly benefit..

Readyboost is NOT a RAM alternative..

Mike,

Do you have any advice on which device is best: I see SanDisk has both a 1GB
SD card and a USB stick?

Go for the Cruzer Micro stick, but don't get one specifically for ReadyBoost
unless you are in the habit of working with a variety slow laptops and
desktops.. if you want a speed boost for your own machine, buy more RAM.. a
1gb RAM stick will do way more good than a 2gb Cruzer ever will..

Mike,

Maybe I don't need it at all, then. I have 4GB RAM on this machine.

No readyboost like many other MS new features in their first iteration
look/sound cool but are of little real practical value to 99% of the
user community. Buy more RAM, Vista loves it.

Hi All:
After reading about Ready-Boost benefits on a couple of online computer
review sites, I got a SuperTalent ReadyBoost 2 GB thumb drive for 29.95 and
now use that on my system. I can't pin down the exact speed increase, but I
can see a noticeable difference when I call up frequently used programs. I
think it is best to use at least as much Ready Boost capacity as you have in
RAM to get the best results. Also, you can "train" your computer to use the
Ready-Boost drive by making sure you open the most frequently used programs
after installing it and then it seems to put those on the ReadyBoost drive
each time you turn on the computer. My computer has 2 GB of DDR2 667 RAM and
ReadyBoost even helps with plenty of RAM for me. On laptops or desktops with
limited RAM I imagine ReadyBoost would be an even more noticeable aid to
speed.

I have 1.5 Gb DDR2 566, I use a 2 Gb SD card with Ready Boost. I've alloted
the full memory. I notice a difference. With a laptop one can see visually
with the LEDs that it is constantly being used. Unfortunately it does not
worl with all apps. I don't agree with the calculation method previously
stated. I think its's more like if I get 400 Mb boost I'm lucky, the
difference is minimal, but untill I upgrade to 2 Gb, it will have to do. 2 Gb
is the ideal. In memory and speed I'm rated at 4.8 and 4.6

Hello skyzyk:
I was wondering if you could tell me the brand name of the 2 Gb SD card
you're using with Ready Boost. I have been using a 256 mb flash drive on my
laptop and it works well but I hate that the flash drive is sticking out the
side of my machine.

Thanks.

Read what Microsoft has to say about it. Very intresting what they say, and
this link will help to answer your question.

http://windowshelp.microsoft.com/Windows/en-US/Help/12428141-2e4c-43ab-8dd2-a6ed6e3b87761033.mspx

If you don't trust the link go to http://support.microsoft.com and follow
the path-
Windows Vista in the Top Solution Center, highlight the "Configuring and
Maintaining" tab and go to "Using memory in your removable storage device to
speed up your computer" This will take you to the same page as the link.

From what I got from that, the additional memory is used as cache and is a
substitute for the hard drive when windows writes the overflow cache to it.
If you have say 4gig of memory the memory boost probably won't even be used,
but then again neither will the hard drive so no performance boost.

Readyboost works, but now can't see drive.

hi all

whenever i put my usb flash drive in my lap top and right click it and try
to use it as ready boost. but it says this device is not compatible to use it
.. i tried another new use of 1 gb in size , but still same problem

<snip>

The flash drive has to meet certain minimum requirements.

The USB Key must be at least USB 2.0
The device must be able to do 3.5 MB/s for 4 KB random reads uniformly
across the entire device and 2.5 MB/s for 512 KB random writes uniformly
across the device.
The USB Key has to have at least 64mb of free space

Rock is right! And I will add that you really should get one that does claim
to be Vista Readyboost compatible. I have tried the 'fast' Sandisk Extreme
III and Readyboost would have nothing to do with it. Vista did barely accept
a 2Gig Cruizer flash drive but it belonged to my wife and she wasn't about to
part with it. Sandisk is supposed to be coming out with Readyboost capable
(or certified??) flash drives real soon now.

What I wound up with is an A-Data PD7 8G (hopefully someday MS will allow
more than 4G or maybe it will come up with other caching applications). It
is a '200x' flash drive but more importantly, it has a very high
random-read/write speeds. Right now you can get a 4G PD7 from Newegg for $43.

For those that do have ready-boost running, you can go to
\HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt (or just search
for EMDMgmt) and look at the stats of your flash-drive devices. If you have
run the 'test' for each of them you will find the values for 'WriteSpeedKBs'
and 'ReadSpeedKBs' are non-zero. My A-Data has 10392 and 5379 respectively
(but I do think the read value is off a bit, I just haven't re-run the test).

I have an x6800, 4G system with a 4-drive raid0 configuration, running Vista
64 and Vista has given me a 4G page-file. One more thing, I will agree with
everyone else, there is no substitute for more ram however I have filled all
4 slots and until 2G pieces comes down in price I am staying with 4G. Since
I do a lot of video/imaging/office/(games), often, at the same time, I am
sure that my page-file is being hit regularly.

If Vista has the ability to read those 'hits' from a 900us flash drive or a
10,000us hard-drive, I hope (and truly believe) that it is going the faster
device. Keep in mind that reading a page-file is a multi-facetted -stick in
the performance eye... Not only does it need to stop reading/writing from
the current location, it has to seek to the page-file (n ms) but then it has
to seek back to the current open file (n ms), so Readyboost can be a 2x plus
advantage is you are currently working with some open files. Also, if I do
leave the system for a bit and the drives spin-down, I also think that Vista
will continue by using the flash-drive page-file, instead of just waiting for
the spin-up...

On a busy day (a lot of X-windows, Outlook, Netmeeting, 10 other apps
running, Word (the pig that it is) still just continues to pop up without any
disk thrashing. The point is, it is not that you need to have little memory;
it is a function of how often you have page-file hits. Readyboost is doing
wonders for even my killer machine.

Rock is right; there are well-defined specifications (or guidelines since you
can always force the issue). And I will add that you really should try to

Sorry for the double post - the forum timed out and then it didn't post my
original until much later. I thought that by somehow having to relog back
in, I had lost the post...

I don't know if this product has been mentioned yet, but I've researched
flash drives and compared speeds. I finally purchased a Apacer Steno 2gb and
it is lightning fast. It's rated @ 30mb/20mb read/write or vice versa.

$32.99 on pricegrabber...directron.com I think.

Transferred some data before I used it as readyboost and it transferred @
31mb/sec. Moved a 140mb file in what seemed like an instant. It's branded as
the fastest flash drive in the world, for now...even has a sticker on the
packaging that says 'Fastest flash drive in the world'. I love it, good
price too.

Hope this helps.

Hey David, I've heard good things about apacer. Could you bring up regedit
and find 'ReadSpeedKBs' and 'WriteSpeedKBs' for your apacer and post the
numbers here?

These are the numbers that ReadyBoost uses and should be good to use as a
comparison metric (at least as far as ReadyBoost is concerned). Every USB
drive you have will have these values and unless they have actually gone
through 'the test' the numbers will be 0. It sounds like your apacer will
probably have the highest numbers so it shouldn't be too difficult to
isolate.

TIA -- joke

'regedit'???

How do I run that app...task manager/run?

You gotta elaborate on that a little more, I haven't run that app before.

Thx.
