Interesting someone posted a link in the ABIT group - no benefits from RAID 0
Well no practical benefits on DESKTOP PCs not servers obviously . The
article points out artificial benchmarks come out much better but not real world use. http://www.anandtech.com/storage/sho...tml?i=2101&p=1 Im flabbergasted because thats exactly what I posted before. Id read it didnt make much difference and that benchmarks came out OK but not a big difference in real world performance. This was long long ago. But then as I posted in the other group I could swear that Id read an Anandtech article later on recommending raid 0 for a desktop. And several skeptics who used to make fun of the ATA 100-133 transition as a marketing scam vociferously started defending RAID. And of course zillions have touted it all over the newsgroups and at various websites. I thought I was out of date and that maybe the newer hard disks and raid technoloigy had made it worthwhile. Hmmmmmmm, subjectively as I posted - it "feels" snappier. This must be a really powerful mass delusion or maybe Im reacting to very tiny differences. Even now as I said - before I did it , a website tested it for gaming and there was no gain in framerates etc but the one thing even skeptics claimed was that things seemed to load faster. In this test they even looked at game loading in FAR CRY and found virtually no advantage and think increased chance of hardware problems doesnt make it worth it at all. Now heres my question - Anyone else feel a subjective improvement in performance? And what kind of apps would have any kind of real world benefit on a desktop? Heres the conclusion from Anandtechs article: Final Words If you haven't gotten the hint by now, we'll spell it out for you: there is no place, and no need for a RAID-0 array on a desktop computer. The real world performance increases are negligible at best and the reduction in reliability, thanks to a halving of the mean time between failure, makes RAID-0 far from worth it on the desktop. There are some exceptions, especially if you are running a particular application that itself benefits considerably from a striped array, and obviously, our comments do not apply to server-class IO of any sort. But for the vast majority of desktop users and gamers alike, save your money and stay away from RAID-0. If you do insist on getting two drives, you are much better off putting them into a RAID-1 array to have a live backup of your data. The performance hit of RAID-1 is just as negligible as the performance gains of RAID-0, but the improvement in reliability is worthwhile...unless you're extremely unlucky and both of your drives die at the exact same time. When Intel introduced ICH5, and now with ICH6, they effectively brought RAID to the mainstream, pushing many users finally to bite the bullet and buy two hard drives for "added performance". While we applaud Intel for bringing the technology to the mainstream, we'd caution users out there to think twice before buying two expensive Raptors or any other drive for performance reasons. Your system will most likely run just as fast with only one drive, but if you have the spare cash, a bit more reliability and peace of mind may be worth setting up a RAID-1 array. Bottom line: RAID-0 arrays will win you just about any benchmark, but they'll deliver virtually nothing more than that for real world desktop performance. That's just the cold hard truth. |
