ReadyBoots via USB

Hi,
The function is working.

Questions:
-is it worthwile to use it having 2G Ram?
-it seems that the double is needed (4G USB) when 2G Ram is in use?
-on the other hand it seems that only a maximum of 2G can be used?

I would like to have the opinion of the experts.

Huib

ReadyBoost has very little to do with RAM
The function of ReadyBoost is to take advantage of flash memory storage
devices by creating an intermediate caching layer on them that logically
sits between memory and disks.
This acts as a write through cache for accessing data on disk.,
After you create the cache SuperFetch populates the cache initially then
then as you access additional files they are cached in ReadyBoost memory and
if you write to disk these are written to Cache then through to disk, so the
next read of the file even if you close it (and assuming that you have not
had it flushed from ReadyBoost) will be from the faster USB memory then the
disk.
A cache of any size will improve performance as is not related to RAM.

I heard (tho i cant find the review now) that the less ram you have the
more benefit you have and theres little to no benefit when you have
alot.
Although what your saying makes sense with newer harddrives having 32mb
cache anyway would it make much difference?

to clarify things even further in a simple manner

readyboost creates a mirror in the flashdrive of the superfetch data on the
hard disk...

this means that even if you pull the flashdrive out, vista will keep using
the data on the disk and nothing bad will happen.

superfetch and prefetch on xp is just a list of where files are located so
they can be accessed faster...

its an index.. thats all.. no part of the actual programs are there.

Why use a flashdrive then to mirror? Because flashdrives have small access
time. Thus the index can be read faster.

Your description is not accurate.
The data held within the USB cache file is NOT just an index.
SuperFetch and XP's older and less efficient Prefetch do use information in
scenario files to watch the process and memory access and usage. BUT the
purpose of SuperFetch is to use that data to prepopulate memory with pages
of data that have been flushed out (as memory becomes available and in
preparation for those pages to be used based on the scenario data) - the
ReadyBoost cache is the place where these pages are prepopulated by
SuperFetch and also cached on their way to disk. SO yes as I explained
ReadyBoost is a write through cache - such that removal does not break
anything since the data is written there on its way to disk - BUT when those
pages are requested by the memory manager they are repopulated to RAM form
the ReadyBoost cache faster then from disk. And in addition to the write
through nature SuperFetch populates the ReadyBoost cache in preparation of
subsequent times when pages may be required as per the scenario files.

So for example - you have a number of applications open and you go to lunch
but a memory intensive process starts when you are away - those application
pages in memory will be flushed to disk but the job finishes before you come
back from lunch so Super Fetch will retrieve those pages and bring them back
into memory before you actually call them again by using the applications.
More interestingly you always open a new application after lunch such as a
mail client this will be in the scenario db and thus that mail clients
initial application load data will be SuperFetched to memory before you have
even clicked the icon. Obviously this is all memory permitting. (if you
had a ReadyBoost memory stick inserted and insufficient memory existed to
SuperFetch to RAM that after lunch app it would be SuperFetched to the USB
stick at least getting you closer to a faster launch time.)

Okay okay, your description may be accurate but its usless the way you
present the information.

I suggest you write what it is in one paragraph in simple words so simple
users will understand what you are talking about.

Dont you know the saying? I would make it smaller, but I didnt have the
time.

If you have 2 gig of RAM it's not worth the effort even if you already
have the USB device. IMO it's advertising hype. Tests show that it's
helps if your system has 512meg of RAM otherwise the "boost" is
imperceptible.

Not just more "accurate" but the actual accurate answer - yours was
completely wrong.

As regards simplifying my answer:-
OK - ReadyBoost improves performance.
If you have a USB stick and it meets the requirements then use it. You
have nothing to loose and potentially something to gain.

Simple enough for you.

Incredible!

Mike DID write one paragraph. Succinct, correct and difficult to re-write
using "simpler"
words. He followed that with a paragraph of examples. He was "spot on"
accurate.

Did you find words that you, or anyone over the age of 14, wouldn't
understand?
