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.

    Quick launch is just...stupid, and ugly. All it is is additional shortcuts, and they waste taskbar space. I think a small menu that appears and disappears on the fly would be nicer.


    If you want Quick Launch to work that way, just add the icons you want into the Qucik Launch folder. Then unlock your taskbar and drag the bar which allows the display of the Quick Launch icons all the way left. Then lock your taskbar. Now you can just click the arrow that shows in the taskbar and it will display all your Quick Launch icons snd "disappear on the fly". It's not perfect, but it's closer to what you want. No wasted space AND you get your Quick Launch icons.

    Quick Launch is one on my favorite features in Windows, because it allows you to quickly launch commonly used programs. I just wish Microsoft would have enhanced it with additional functionality. I have to use a 3rd party program to the features I want to Quick Launch.

    Despite the issues with x64, that's the version I will get when I migrate to Vista. I just wish Microsoft would have been able to release Vista as a x64 only OS. The availability of a 32bit version of Vista will keep the migration to x64 to a crawl.

    I cannot stand it... it does drive me nuts...
    Will most users not use it? I highly doubt that. Turning it off is not as easy as "1...2...3... OFF!"
    It does involve some tinkering to get it to turn off...
    The problem is, this is how things should have been from the beginning, but we have been spoiled by the lack of security. I really do not find that it gets in the way or anything like that.

    I'm not sure if I would QUITE go that far... given the vast majority will have NO CLUE on how to turn it off…

    Just my thoughts.

    One of the many links I found by going to start and typing into the new Windows Search box located there in Vista :)

    Search is going to be one of the biggest selling points, works much better in Vista than it did in XP (I've used it in both).

    Jarred's right, it's actually very easy to turn off. Although if you turn it off, Windows will bug you to no end in their protection center to turn it back on (which you can turn that off too :P). I ended up turning it off when trying to install drivers for my Realtek ALC888 codec on my Gigabyte GA-965P-DQ6, because at first, the driver install kept looping and asking if I really wanted to install unsigned drivers. I kept hitting yes, they kept going back and prompting me. After Vista said the driver install failed and asked if I'd like to run it in a higher privileged mode, I did so. Then the install told me that I needed to be <b>ON VISTA</b> to install the drivers. I ended up installing a different set of drivers that I didn't even expect to work with the ALC888-DD.

    Also, to add in with drivers, UAC caused a weird issue with the 100.54 drivers from nVidia. When UAC prompted you, the screen fades into a B&W gray-ish hue ( kind of like when shutting down XP ), but when you're running DualView on Vista and you hit a button to close the prompt (being it accepting the action or whatever), the other screen literally freaks out. It goes to some weird graphical pattern for a second and then goes back to normal. Although the problem doesn't stay, it's quite noticeable out of the corner of my eye.

    http://www.google.com/search?hl=en&q=vista+tur...">Easy as 1-2-3, or just http://technet2.microsoft.com/WindowsVista/en/libr...">get it from Microsoft. My feeling is that most people will *want* it off, even if they don't know how to shut it off, and I'll reword that sentence appropriately. :)

    Is there still Memory Address limitation with the 32-bit version of Vista?

    Like say, I had a SLI board (eVGA 680i in particular), and I wanted more than 2 GB, would I still hit the 2.25 GB wall due to address bus or does Vista gets around this and is actually able to address the 4 GB if I had that installed? Or is my only option is still go with x64 version of Vista....
  • JarredWalton - Thursday, February 1, 2007 - link

    It depends on motherboard and BIOS as well as the OS. AFAIK, you can't get more than 3.5GB (and often only 3GB) of accessible memory with any 32-bit OS on x86. The top 512MB is reserved. Perhaps it is OS dependent and you can get closer to 4GB, but for MS operating systems I think it's always been 3.5GB max. Whereas in XP you needed to use the /3gb switch for the OS, on Vista you use:

    BCDEDIT IncreaseUserVA [size]

    Or something like that. I don't know if the maximum is any different on 32-bit Vista than 32-bit XP, but I would bet it's the same.
  • Ryan Smith - Thursday, February 1, 2007 - link

    You're almost right. It's possible to get all 4GB(and more) on a 32bit system when using Physical Address Extension. However most consumer level boards don't implement this at the hardware level past what's required to support the NX bit(which also requires PAE), so most people can not get all 4GB in 32bit mode. With XP and Vista, you can get all 4GB as long as PAE is fully supported, however actually using PAE to get 4GB+ brings about some compatibility/performance problems, which is why 64bit addressing is a cleaner solution.

    The /3gb switch is an entirely different thing, it adjusts the 2/2 split between user processes and the kernel so that user processes can go up to 3GB by taking some memory from the kernel's space(which also can cause problems, oy).

    I haven't read the article yet (am doing so in a minute) but just a thought by having a first look at the article index: I was wondering what impact Aero would have on power consumption. We know that it runs the UI on the graca, so the graca would be in use all the time. Is the load on it high or low? You can collect a lot of data on such a thing (power consumption while idling, moving windows around, ... on vista with aero, without aero, on winxp...)

    It could be that it gets a mention in the review, it's just not apparant from the index. I'll apologise beforehand if it does.
