Wow, thats a feature I've never heard of. I may think about getting vista now. Well whenever the dx10 thing is fixed with nvidia drivers of course.

It's a quick fix for a less than acceptable product in my opinion. No thanks I will stick with XP

Vista is acceptable, Its just got alot of annoying security features. I only give XP two more years before its obsolete. I really don't want to switch, I've grown fond to XP, but what can ya do?

Ready Boost is completely unnecessary with 1GB or 2GB of RAM. It's better to spend some extra money on more RAM. It is a gaming system after all. 512MB was standard far too long ago. All this does is get you a few more FPS at the cost of tying up your USB key. It's not worth it unless you have a USB key that is rarely used.

My current computer had 8 USB 2.0s on it. I only used 2 of them. Can never have enough usb ports.

Who'd be foolish enough to install Vista with only 512MB of ram anyway?

Nevermind, i know someone who just got an emachine laptop with Vista and 512MB of ram witha slow T2050 processor. (NOT ME!)

But its weird to see that readyboost with 4GB flash is slower than 2GB...

That is a great interview. My head really hurts after watching the whole 48 minutes from the developer of the stuff. Long story short though was that ReadyBoost is working independently of other volitile memory and acts as more of an aid to buffer of your hard drive.

More so interesting was the the whole concept of a "smart operating system" that uses SuperFetch. Kinda neat that your computer figures out your pagefile based on past habits that you have as a user, it learns and remembers your preferences.

BTW, I tossed a spare 2gb thumb drive into one of my ports and it seems to run fine. I have yet actually run a performance test to see any I/O increase as advertised.

I just upgraded to 2GB of RAM from 1, and I would have to say that if you are gaming on Vista, 2GB is a requirement. The difference is amazing.

ReadyBoost would most definately help if you have 1GB, would be less noticeable with 2, however.

More RAM is always the better option though.

You can find some very interesting statistics on SuperFetch in the event viewer under Applications and Service Logs --> Microsoft --> ReadyBoost (yeah, I know it says readyboost, but it actually has SuperFetch cache information as well). For example, look at these stats:

Summary of ReadyBoot Performance:
Io Read Count: 16424
Io Read KB: 381702
Cache Hit Count: 14094
Cache Hit KB: 261343
Cache Hit Percentage: 85.813443740867
Cache Fragmentation: 9.73164044523991
Compressed Data Size KB: 246639
Raw Data Size KB: 419212
Compression Ratio: 1.69969530428013
Cache Size KB: 270991
Boot Prefetch Time us: 31929002
Boot Prefetch Bytes Read: 310747136

Notice that my cache hit percentage is almost 86%. That is outstanding and explains why nearly all my apps open in less than a second, including ones like Photoshop which typically takes 30 seconds or so to get up and running in XP.

It's even more interesting if you filter on event id 1015 and look at the history of the performance. Over the course of using Vista my hit percentage increased as follows:

• 1/18/2007 15.6%
• 1/20/2007 29.8%
• 1/21/2007 58.7%
• 1/22/2007 76.3%
• 1/29/2007 83.1%

The improvement curve is quite steep, which just goes to show that my usage habits are very predictable.
