what is speedboost?

what exactly is speedboost. does it only work in vista and not xp? also will any flash drive do it or do you need a usb drive that is specifically designed to do it like the pny ones?
 
in the article it says vista checks to make sure the card is fast enough. does that mean you actually need a usb drive that is specifically labeled as being optimized for readyboost?. in preactice does readyboost make a visible difference?
 
Readyboost shouldn't make a big difference assuming you have enough RAM. But yes, Readyboost needs a fairly fast drive, and before Vista, there were flash drives that didn't make the cut.
 
A reasonably quick thumb drive is needed.

Regarding performance beneift, it depends on your system - If you have less than 2GB of RAM, it should help. If you have 1GB or less, it will make an easily noticable difference. On the other end, if you have more than 2GB of RAM, then there's little benefit.
 
I was gonna recommend a Corsair Flash Voyager GT flash drive, but I see Newegg has "deactivated" them and isn't selling them anymore. I dunno if that means there's a problem with them or if Newegg has just dropped them for some other reason, but I'd check into it before ordering one. Just know that the 'regular' Flash Voyagers aren't capable of ReadyBoost -- it has to be a GT model (they have the red & black color scheme as opposed to the teal/black scheme of the regular Flash Voyagers).

Just lettin' you know in case you had any thoughts of getting a Corsair drive.

To answer your other question, ReadyBoost only works in Vista.

Good luck.
 
thanks for that info. so i guess that means unless a drive is specifically labelled as being ready boost capable then it isnt. so the cheapo kingston 4 gigs that are 4 for 40 at frys are not but the more expensive pny ones are
 
No, that's not true. I have a 1GB stick that is not labeled readyboost but it works just fine. On my laptop, I use a 1GB SD card for readyboost since I can just leave it in and not have to remember to plug in a USB thumbdrive. and it works well.

Just plug in any thumbdrive and right click on it. There is a readyboost section. It will test the speed of the device and if it's too slow it just won't let you use it. But if it's fast enough it will whether labeled readyboost or not.

If It's a full USB2 device, it will likely work just fine.

RAM is so cheap nowadays one might as well just get more of that vs a flash drive.

Readyboost is also used for return from hibernation. So yes, more core memory is better but I still keep a 4gig readyboost drive in my 32gig system for this reason.

 
Bill, I know that ReadyBoost is limited to 4GB on 32-bit systems, but do 64-bit systems have the same limitation? Or can they take advantage of, say, an 8GB ReadyBoost cache, if you have 8GB of RAM?

Also, how does a 4GB ReadyBoost drive help with hibernation from a machine with 32GB of RAM? I can't see storing the entire hibernation file on the 4GB USB flash drive, even with compression. So how does it help?
 
From everything I've seen and docs readyboost is limited to 4gb even on >4gb systems. As for hibernation return, your right the whole file eventually needs to be read but the ready cache stats were showing some of that was consitently coming from the cache.
