Hi,

I'm trying to use a sandisk USB memory to extend the memory of Vista (for
the prefetch)
But Vista says that the memory doesn't fit the performance requirements.

what are these requirements?

what type of USB flash drive or other system could be used with Vista?

thanks.

Jerome.
 
I'm not too sure what they are yet as they haven't released specifications
yet, however I'm guessing USB 2.0 must be somewhere in there...

well... I'm using USB 2.0 devices.

how can verify the speed really used and if the device is detected as USB2.0
or 1.1?
 
Not too sure you can actually do this within Windows... however if you are
using a USB 2.0 device and you insert it into a USB 1.1 port, a little
systray icon will make an appearance saying that "this device can go much
faster". Then it'll help you find the USB 2.0 ports on your machine.

Quite handy ;o)

Yes, 2.0 UBS Memory sticks are recommended for Windows Superfetch/Ready
Boost. If it is you will be asked if you'd like to use this device to speed
up system performance. You also have the option to use Windows ReadyBoost
with an already connected USB flash device by accessing the properties of
that device. You can choose to allocate part of a USB drive's memory to
speed up performance and use the remainder to store files.

I believe the first time (or any time afterwards if you don't first select
it) on the AutoPlay menu - it'll give you the option for this at the bottom
:o) So there's no difficulty in selecting a device - simply plug it in and
if it's compatibile, it'll give you the option to use it as a
Superfetch/ReadyBoost device.

I know all of this.
my question is:
what is the minimum requirement?

because Vista says that my device doesn't have the right performance to be
used for the prefetch.
the page where we can setup this configuration display this message
instead-of the options to use this memory.
 
It's hard to say - SuperFetch (although some may regard as an older
technology) is still in beta as is the operating system. There'll be more
documentation coming out in the following weeks/month or so.

I have the same issue... I have a 2GB Memorex USB drive and it also says it
doesn't meet the requirements. My laptop is a Toshiba M4.
 
I have the same issue. Memorex 2GB USB. Beta 2 says my USB memory stick
doesn't meet the requirements. What are the requirements? Anybody actually
has this working? My laptop is a Toshiba Tecra M4.
 
Hi

with the Beta2 this works fine now,.
in the beta 2, windows do a quick test to verify the speed of the device,
then use it or not.

I have a 2Gb memory stick which is not used because "too" slow, and another
memory (from my camera) which is recognised and used by Windows.
the 2 devices are connected through the same USB connection, so the
difference is linked to the speed of the memory himself.
My 2Gb sandisk is too slow and my compact flash is good enoguh for vista.
 
It isn't completely related to perceived read-write speed. It's access
speed-related. I have a brand new Corsair Flash Voyager, which ranks among
the fastest sustained R/W speeds, but SUCKS in access (seek) time. Where
other thumbdrives have 1-2 ms, this otherwise FAST Corsair has 20 ms, hence
unusable for fast caching of small portions of memory. Go figure.
 
I have a Verbatim 1 GB I bought 3 months ago, and Vista states it does not
meet the speed requirements for SpeedFetch. What the heck Microsoft! I think
this is a conspiracy of Microsoft and the PC makers to force everyone to
update their computers and accessories in the next year.
 
Remember: you are using this device to speed up your computer. If it is not
fast enough, it might actually hamper performance. I tried to use a 256MB
camera chip and apparently the space on the chip is 235MB, and is, therefore,
not usable for ReadyBoost.
 
Having just installed Beta 2 (Public) I would like to use my USB memory stick
for Ready Boost/Super fetch.

I have been unable to find any referance to Super Fetch or Ready boost. None
of the things mentioned in earlyer posts appear to be any help. I dont see
any options in the propertys for the device or get any option to turn this
feature on when I insert the stick.

Any pointer would be usful...
