Western Digital's Raptors in RAID-0: Are two drives better than one?

Office Productivity Performance - SYSMark
SYSMark's Office Productivity suite consists of three tests, the first of which is the Communication test. The Communication test consists of the following:"The user receives an email in Outlook 2002 that contains a collection of documents in a zip file. The user reviews his email and updates his calendar while VirusScan 7.0 scans the system. The corporate web site is viewed in Internet Explorer 6.0. Finally, Internet Explorer is used to look at samples of the web pages and documents created during the scenario."
The Communication test generally shows decent differences between drives, but we see here that RAID-0 brings just over a 3% performance boost. In one of our most disk-influenced tests of the suite, the nail is beginning to shut the coffin for RAID-0 on the desktop.
The next test is Document Creation performance, which shows very little difference in drive performance between the contenders:
"The user edits the document using Word 2002. He transcribes an audio file into a document using Dragon NaturallySpeaking 6. Once the document has all the necessary pieces in place, the user changes it into a portable format for easy and secure distribution using Acrobat 5.0.5. The user creates a marketing presentation in PowerPoint 2002 and adds elements to a slide show template."
Once again, we see identical performance between the RAID-0 and single drive setups.
The final test in our Office Productivity suite is Data Analysis, which BAPCo describes as:
"The user opens a database using Access 2002 and runs some queries. A collection of documents are archived using WinZip 8.1. The queries' results are imported into a spreadsheet using Excel 2002 and are used to generate graphical charts."
To finish off our individual SYSMark tests, our comments are little more than echoed once more with these results; RAID-0 does nothing for desktop performance.

I liked the diagrams for RAID0 and 1. Would be cool to see 3,4,5, and 10 drawn out too, but that wouldn't of been relevent to the article.ciwell - Thursday, July 1, 2004 - link
Excellent article...and for those who think it is faster experientially: it is all in your head. ;)SilverBack - Thursday, July 1, 2004 - link
I'm using two RAID 0 arrays.A8V mobo with a promise 378 controller and the onboard VIA as well.
I prefer the system this way. It just makes the whole windows experience faster.

Any subjective comments on whether the system using RAID-0 feels any smoother? A lot of people comment that P4s with Hyperthreading produce a system that just feels more responsive regardless of whether it's really any faster.I find the best thing to do (under Windows) when you've got two drives hooked up is to move your Virtual memory onto the one which you use less. There's all sorts of tricks you can use to distribute your system load without necessarilly using RAID.

I recently did a test by copying a few GB of data from a WD 160 GB drive to another WD 160 GB drive. It took about 4 mins.I then renamed the folder that I just copied and then copied it back to the original drive, and again got about the same time, with only a few seconds difference.
I timed my boot from Windows from the time the OS takes over, all the way to the desktop, and it took about 35 seconds. I do NOT have any bloatware or junk on my system.
Finally, I enabled RAID 0 for these two drives. Now the same version of Windows boots up in about 25 seconds (not as fast as you'd think). Also, copying the same folder from my 3rd hard drive to my RAID 0 drives is taking 1 minute and 45 seconds. The seek time itself may be still slow, but once you get the data going, it'll definitely help out.

I play eve online and i can be running at any given time 3 clients of eve a music player / video / or a text to speech program a browsing client with usually 5 - 7 tabs and sometimes i even want to be able to extract files at the same time I think for that kind of usage RAID 0 would be very worth it, did you even consider a lot of users do multiple demanding tasks at once?qepsilonp - Saturday, November 5, 2011 - link
while yes when running one application RAID 0 is usually useless but when like me most of the time you are using 2-3 clients of a heavily HDD relent game where sometimes it takes a while to get the files for the 3D images and sometimes because of that your they wont show up on the screen for sometimes 5 seconds and i know its not anything else but the HDD because i have a new computer and the only piece of hardware that hasn't been updated is the HDD and im still getting it.if i was able i would also be running a HD movie or have my computer read a book to me with a text to speech program or be playing music and also maybe extracting something with Winrar you cant tell me that with all those IO's that RAID 0 wouldn't help at all, considering the game im playing is eve online and when i jump in and a gate can have 1000 ships on it thats maybe 32 different ships types which have to be gotten from the HD which is probably something like 100mb times 2 - 3 thats 64 to 96 IO's thats if theres isnt multiple files that need to be called up for 1 ship type so yeah I think in the deck top for power users there is a place for RAID 0
