can i use my toshiba 1GB SD micro card on laptop for ready boost
also i have 512mb usb drive. can this also be used as same.

Why not try it out to see?

In my opinion Readyboost is somewhat temperamental. I have a Sandisk Cuzer
2GB USB drive which 'is' ReadyBoost compatible but, when the USB drive is
inserted into a USB port ReadyBoost sort of says 'shall we play today or
not?' In other words sometimes ReadyBoost will accept the cruzer USB drive
and allow it to be used by ReadyBoost and at other times it say 'no, sorry
not compatible.'
If you have less than 1GB of memory then ReadyBoost 'may' giver a slight
boost to performance, but i don't think it is blindingly obvious. Using it
on my machine with 1.5GB RAM there was no difference whatsoever.

To be usable for ReadyBoost the device must meet certain minimum
requirements. Since you already own them the best way to find out is just
try it out.

Here are the 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

I'm not meaning to challange (too much but to a greater extent, ReadyBoost
really doesn't have much to do with the amount of memory in your system. If
you have 1G and never do anything but read outlook express newsgroups,
ReadyBoost probably wouldn't help at all. On the other hand, in my system
with 4G ram, my Readyboost addition really made a huge difference.

I work remotely and have: 8 or 9 Reflection X windows open continuously;
Outlook; Jabber; lots of digital imaging; IE7; and I use one-note. When I
open Word, I get very little disk thrashing and most things usually just pop
up. Switching between all of the different screens is much faster with
ReadyBoost than without.

To be fair, you should be explaining that the benefits of Readyboost are
really seen if you hit your pagefile often and if you don't have a taxed
system, it may not help much (and then always disclaim everything with a
ymmv)!

Have a good one.

Readyboost is specifically designed to increase performance on machines with
512MB of RAM. Anything over 1GB of RAM and, as i've said, performance
increase is negligible. With 4GB of RAM you shouldn't even need readyboost.

I too use memory intensive applications each day and can honestly say that i
haven't noticed a scrap of difference between using the PC without
ReadyBoost and using it with. As ReadyBoost is a long term usage application
it is impossible to see a sudden surge of performance as soon as the
ReadyBoost USB drive has been inserted. It is only after a period of some
weeks of using ReadyBoost that you are likely to see improvements.

One of tha main problems, of course, is that not all USB drives are
currently compatible. Even the Cruzer i am using is temperamental. If i
insert it into a USB port i am told it isn't compatible (when the label
clear states 'Enhanced for ReadyBoost'). As the USB Readyboost drive is
supposed to stay in the USB port at all times, when the PC is rebooted the
ReadyBoost drive doesn't work at all.

Maybe, if they make improvements to readyBoost for Service Pack 1 of Vista i
may change my mind about ReadyBoost.

Perhaps we are really talking about two different products. I am referring
to Readyboost and it really sounds like you are speaking about 'SuperFetch'
which does require training (" It is only after a period of some weeks of
using"). Readyboost just mirrors the pagefile and redirects pagefile
read-request; it has no learning profiles associated with it (only requires
ecache.sys). If you have better information or more facts I would be very
interested to hear them.

Regarding the Cruizer flash-drive: _Only_ the very recently released (April
5) "Cruizer Contour" 8 & 4G, claim to be ReadyBoost compatible, _all_ of the
older Cruizers (like mine and possibly yours) are not up to par and do not
make that claim. Mine sometimes gets approved and sometimes it just fails...
mostly it just fails the performance test. I finally went with the MUCH
cheaper A-Data PD7 (from Newegg) and it has been completely satisfactory. It
is really easy to verify your numbers with those that Rock listed below...

If you (not you John, you in general) are not afraid to use regedit and have
run the performance test, you can search for EMDMgmt which will contain a
list all of your flash drives. In those flash-drive registry entries, they
will include two fields, ReadSpeedKBs and WriteSpeedKBs. With my (purchased
in January) Cruizer, I get a ReadSpeedKBs value of 3127 and a WriteSpeedKBs
of 2191. Looking at Rock's post (below), you can see that these numbers are
just very slightly below the required specs. My A-Data PD7, on the other
hand has 5379 and 10392, respectively. YMMV (it is easy to look at the real
numbers before chasing any other ReadyBoost concerns)

FWIW - While shopping for something else, I ran across this same subject
today and the performance measures below at
http://www.kingston.com/flash/windowsvista.asp

I may try it myself if the chats here & elsewhere indicate there's benefit.

Kingston claimed at time I've quoted site that: ReadyBoost Performance** —
Exceeds the minimum Microsoft ReadyBoost performance requirements for USB
drives of: 5 MB/sec throughput for random 4k reads across the entire device,
3 MB/sec throughput for random 512k writes.

**Speed may vary due to host hardware, software and usage
