Impact of Drive Performance on ReadyBoost

For our ReadyBoost tests we used a modern hard drive, a Western Digital 500GB drive. We wanted to find out if ReadyBoost had an even greater impact if your system has a slower drive, so we switched to a five-year old Western Digital WD1000 100GB drive to see how ReadyBoost's impact changed, if at all. We took three benchmarks - the Movie Maker, Word, and Application Close tests - and ran them on the WD1000 to compare performance scaling with ReadyBoost.

ReadyBoost doesn't seem to do any better with a slower hard drive, although we'd suspect that you may see bigger gains on similarly old notebook drives.

ReadyDrive

The last I/O feature before we get to networking is ReadyDrive, a technology that is closely related to ReadyBoost. Whereas ReadyBoost is designed for use with external flash memory, ReadyDrive is based around internal flash memory, which has been cropping up in recent years in so-called hybrid drives (hard drives featuring large amounts of flash memory as a cache) and with Intel's Robson technology (which puts flash memory right on the motherboard). In both of these cases this internal flash memory has the added advantage of being unremovable and hence more reliable (as a USB flash drive could be removed at any second along with its cached data), which opens up a few more uses of flash memory as a cache.

On top of the standard caching uses to improve general performance, ReadyDrive can use this internal flash memory as a way to improve hibernation recovery and boot times, as flash memory could be a faster non-volatile data storage than a hard drive. Use of this flash memory also stands to reduce average hard drive power usage (a particularly important item for notebooks), as caching of data can allow Vista to spin the hard drive down more often. Finally, integrated flash devices are likely to be faster overall than most external flash drives, for a couple of reasons. First, pulling data over a USB connection tends to require a bit more work. Second, we would expect most integrated flash devices to use higher performance flash memory.

Coming up with tests for ReadyBoost was a bit tricky, but testing ReadyDrive is even more so. Besides creating some reasonable test scenarios, you also need hardware that supports ReadyDrive. It is also likely that various ReadyDrive devices will offer differing levels of performance. For these reasons, we will hold off on trying to benchmark ReadyDrive for a future article.

    Did you guys run the 64-bit tests solely on the Intel Conroe platform? Or did you test an AMD based platform as well? Recall that Conroe has a few performance enhancing features that *only* work in 32-bit mode (branch fusioning, for one - some decoder limitations as well).

    That could explain why a Core 2 Duo system might have seemed slower in 64-bit than in 32-bit mode.

    SuperFetch is by far my favorite new feature of Vista. I put my first copy of Vista on my laptop, which has a 5400 RPM hard drive. Opening apps Outlook and VB .NET 2005 EE weren't really slow under XP, but there were those few extra seconds it took to load that would often leave me tapping my finger on the palm rest while I waited. Now under Vista, Outlook, VB .NET 2005 EE, and IE7 all seem to be able to fit in the SuperFetch cache, as they all open nearly instantly with just 1 GB of RAM. I'm considering upgrading to 2 GB just to see what else I can get to open really fast. :D Reply

    Was superfetch disabled when you tried the Readyboost feature in Vista? Whichever way you ran the test it bears mentioning. If it was off, then how does it do with it on? If it was on, it may make a difference in how it relates to XP.

    Also, as I understand it Vista has a system backup now that creates a "ghost" of the drive. Could you check out this feature and get back to us?

    I'm not sure it's possible to disable SuperFetch, so I'm pretty sure all testing was done with it on. As far as the "ghost" goes, that's part of System Restore which can be disabled quite easily. I'll have to let the other editors say whether it was enabled or not, though. Reply

    What drives me nuts are the plentiful comments about how slow Vista is compared to XP. I mean, anybody hear this before when MS came out with a new OS ? Same thing for XP,W2k,98 ... ad nauseum. Yea, its a new Operating System with more 'toys' built in, what were you expecting ? You aren't gonna load it on your P3/256 RAM rig and enjoy the Vista 'experience'. Damn, this thing runs better than XP on my rig !
    It's understood that it won't be as quick (keep in mind the OS has been available for retail purchase ... 2 days now) as XP, but drivers will improve that performance gap to a smaller number within 3 months time. I waited until just last year to upgrade to XP (W2K all the way for me !) but find myself with 2 copies of Vista and would prefer to dual boot one and go Vista all-out on the other one.
    I griped back in my W2K days about being forced to upgrade due to content (MS games were announced that would only run in XP) so this time around I will be ready.
    DX10? Marketing genius !!! We shall force an upgrade upon the masses !! I upgrade frequently, so DX10 and its graphical splendor is a priority, but if I would have to fork over $200 to actually buy Vista, I would be less than impresssed with DX10 eye candy.

    Hopefully, now, finally, Anandtech will start testing motherboards for stability while loaded with the maximum amount of memory. So if the MB supposedly supports 8GB of RAM, you test it with that much, and make sure its stable. I've wanted this done for years... memory is expensive and it sucks to load a MB up and find out it doesn't really work or only works if you cut the speed in half.

    Thanks.

    ... no mention of DRM then? No mention of Linux? Personally I hate Linux, but I've switched to it because of Vista's use of DRM. Not all Microsoft's fault, but they put it in there... My computer, my hardware, I choose what to do with it, not MS, not media companies. Why shouldn't I be able to watch High def content on my old, and once expensive non-HDMI LCD screen?

    Get a Mac, Apple is the lesser of 2 evils, they aren't the 800lb gorilla in the room. MS could have told media companies to stuff it. Apple has no choice, it's too small, yet their the ones that forced DRM-Light(TM) on the media companies. MS had the media companied force DRM-Oppressive(TM) on them... how the heck does that work?

    I can't believe you left Linux out of the final comparison, is it as capable an OS, yes. Not nearly as user friendly, but it also has 0 DRM, doesn't phone-home isn't beholden to any one entity. I'm not against DRM, as a whole, just Vista's implementation. BS like MS creating D3D to subvert open standards like OpenGL, then removing it from the OS, using it's monopoly-based-ridiculous-margins(TM) to finance D3D's uptake, again rather than take an existing standard and expanding on it. They create their own to reinforce their monopoly. I know why they do this stuff I'm just peeved so many people don't give two flying f...

    grr...

    Youre insane dude.. No offense but there just isnt anything else to say. Posts like these always read like the transcript of a Weather Underground meeting in the sixties. "FIGHT THE POWER!!! FIGHT THE POWER!!!"

    Look out! The black helicopters have deployed from the underground helipad in Redmond and are circling!!! Send up the penguin symbol to summon the dynamic duo - Torvald and Stallman!

    There is no more or less DRM in Vista than in XP, or even OS X. The platform does not determine the playback of DRM'd media, the content does. The choice is simple: If you want to play back DRM'd media, then you have to support the decryption scheme that the media requires to decode it. In so doing you have to legally accept the limitations defined by that DRM scheme.

    It is no different for OS X, Linux, XP or any other OS. They either support the DRM schemes or they do not get to playback the media that uses them. This is why it is unlikely that you will be able to play DRM'd High Definition content anytime soon on Linux. That is the alternative, no support for the content at all.

    Also, you can play high definition content on Vista just fine without HDMI/HDCP on your monitor. You simply cannot play back such content if it is coupled to a DRM scheme that requires HDCP, but that is true of every OS. Any other HD content will play back without issue.

    Again, there is no difference between DRM on Vista from DRM on any other platform.

    The DRM in vista is the major reason that I will only install it if physically forced to. Having bought a new Dell in order to get their very nice 24" LCD last december, I have an upgrade coupon which will lie unused until/unless the DRM can be disabled. MS refuses to display HD on my new monitor using Vista? Screw em. Reply
