readyboost/superfetch question

[her34]

when you startup your computer is there heavy hdd activity because it's loading up the superfetch info into ram?

if you're using readyboost, does the flash drive get re-written to after a reboot?

from this review, it seems like readyboost is useless after 2gb ram. do you find this to be true with your system?

I would guess 'yes' to your first two questions.

Precisely. And it's low priority, so don't worry about it, anything you choose to do will override that I/O.

I am fairly sure that nothing is persistently cached through reboots due to the removable nature of the drives. However, if you dig deep enough, you can configure your device to be non-removable, which does definitely persist over standby, possibly over a reboot. But if you pull the stick out, you BSOD, so it's not an easily accessible option.

Well, it provided a benefit even with 2gb, however small it is. A USB stick costs $20 or so, so I can't think of a good reason not to use it. A boost is a boost, however small.

Even with 4GB of main ram,my 4GB USB flash drive gets used.

My understanding is that even with 4gb of memory, readyboost is still going to get decent use managing what should be cached by superfetch.

They're brand new features with a lot of potential for the future. I saw a clip from one of the MS devs talking about it and whats to come, including more customization of whats to be cached. It'll be pretty sweet when I can tell windows to precache an entire game, goodbye load times. 🙂

It has to be paged in from disk at some point no matter what and if you have the memory for it you can already do that, on bootup just write a small script to read all of the game files at once and poof, they'll be in the filesystem cache.

ReadyBoost and superfetch is superb and improves the performance overtime. However it doesn't make games load faster- because it a bad idea to pre-load Games in the memory
