    So what's Turbo Flash?

    Your first thought is wrong. It's not a way to quickly expose one's self in public. Oh no. It is, in fact, much more decent than that.

    So is there a NAND/NOR flash memory issue involved? Wikipedia says that NOR has 4KB blocks as opposed to NAND's much larger blocks. If anyone understands the technical details and can explain them in a sentence or two I'd be quite appreciative.

    This seems like a big gimmick really, are there any benchmarks that show ReadyBoost actually being useful?

    Sounds interesting, I'd also like to see some benchmarks before I buy into any hype though!

    yeh id like to see some benchmarks. what they say on paper and what they achieve are normally 2 different things

    i was playing with this feature during the vista beta when i first read about it.

    What i hoped i could gain from was the fact that the box in question has only 2 gig of ram, not quite enough to run without a page file. Now back then a 2 gig flash stick was£40. A fast one too, now we're more into 4gig teritory. 2 gig of ram will set me back more than £100 more!

    So its faster than an HDD for random access, but more than that, often you need to commit when your loading something from the HDD. In the ideal world you'd only page when your idle, nothing else is going on, regretabbly you often have to page when your using more memory all of a sudden, like when your loading a program off the HDD. If you've only got one HDD, its perfect solution because at present the HDD will spend a lot of time switching between the data thats been loaded, and the data thats been commited. Here is where there is a lot of potential.

    straight off, this clearly isnt going to be aimed at the performance users market - the bandwidth of usb2 is tiny compared to that of your ram.. however..

    this is a great product for those home users who want to upgrade thier pc. lets say a 2 gig one of these gizmos costs £50, compared to £40 for cheap ram (made the prices up, no idea if their accurate).. now a sensible enthusiast wouldnt pay £10 more for something thats slower, but, if you dont want to open up your pc, its a great option - sending your pc in to have ram fitted will probably cost ~£25 - saving you £15. and you can transfer it pc to pc.. brill imo

    I agree with 5lab, definitley good for the home user, such an easy upgrade and easy(ish) to understand on that level. 'Stick it in and your computer will go faster'.

    Is there a Active Directory Group Policy setting to disable their use? Otherwise it would be a bit of a nightmare because every deskside expert will have one and wax lyrical to their office mates and so on and so forth.

    Readyboost has a lot of misconceptions - try this as a primer: http://blogs.msdn.com/tomarcher/arch...02/615199.aspx

    It's not a replacement for RAM, it's used very cleverly for very specific caching operations where a hard disk is slower.

    "Q: How much of a speed increase are we talking about?
    A: Well, that depends. On average, a RANDOM 4K read from flash is about 10x faster than from HDD. Now, how does that translate to end-user perf? Under memory pressure and heavy disk activity, the system is much more responsive; on a 4GB machine with few applications running, the ReadyBoost effect is much less noticable."

    Looking for benchmarks also.

    Will this speed up game loading and such, or will it only be usefull for general computer use?

    also. overclockers.com (yes, thats overclcokers.com not .co.uk) have had a couple of good articles regarding this recently
