Liquidfire Posted July 14, 2006 Posted July 14, 2006 http://img117.imageshack.us/img117/268/scr...fbenches2gu.jpg a couple quick questions about the array....i think its pretty self explanatory i may have left a few things out tho so feel free to ask away. 2xsata II barricuda 320Gig perpindicular drives Raid 0 16/4 if i turn read caching off up till about the 16 test the read takes about a 50% decrease in MB/s but the burst rate goes thru the roof. :drool: im a bit confused as to what i should be going for Share this post Link to post Share on other sites More sharing options...

cerupcat Posted July 15, 2006 Posted July 15, 2006 Here's my first attempt at RAID ever. 2 x Hitachi SATAII 160gb in RAID 0 To be honest, I don't know much about what all these graphs means. Especially from the ATTO one. Here's the pictures: The second drive above is a WD IDE 160gb (not RAID). It's the top one that counts hah. From looking at other's benchmarks, it seems my drives are doing well? Share this post Link to post Share on other sites More sharing options...
red930 Posted July 18, 2006 Posted July 18, 2006 @cerupcat You need to pay attention to the settings in ATTO. Share this post Link to post Share on other sites More sharing options...
red930 Posted July 18, 2006 Posted July 18, 2006 Here's the easiest way to test Stripe/Cluster performance on your rig. Build your OS on a single drive. Build the RAID-0 array and set the Stripe to your first test size. Use Disk Management to format the array with the first test cluster size and start benchmarking. Once you're done testing with those settings, format the drive with the next cluster size. Do this until you've exhausted the available cluster sizes. Break the array and build it with the next test Stripe size. Continue your testing with different cluster sizes. Once you've found your Stripe/Cluster performance sweet spot, break the array one last time. Remove the single boot drive, build the array with the Stripe/Cluster you choose and install the OS. This is the only way to get the optimum Stripe/Cluster for your particular rig. Be aware that, in general, a two drive RAID-0 array has a sweet spot of 1/4 stripe to cluster ratio. A stripe size of 16K likes clusters at 4K. Share this post Link to post Share on other sites More sharing options...
sixpack_li Posted July 18, 2006 Posted July 18, 2006 Hi all! I'm doing benchmarks at the moment... What applications do you find work better with RAID 0 arrays as opposed to single drives? For me its just file copying and of course benchmarks. What functions are you using your RAID arrays for? Share this post Link to post Share on other sites More sharing options...
acurax Posted July 20, 2006 Posted July 20, 2006 EDIT: Ok, so I decided to ditch my 2-year-old Raptor for the Seagate RAID array. I ended up slipstreaming the RAID drivers onto a WinXP unattended install disc and all is good so far... I've never done the slipstream thing before, and it's pretty sweet. I just XP installed, and in Device Manager I checked out the driver of my Nvidia Stripe disk and it says its dated 7/1/2001 from Microsoft...is this supposed to be like that? Also, am I supposed to install the nvidia SW drivers? Will these change the above issue? Share this post Link to post Share on other sites More sharing options...
Guest Milkshake Posted July 20, 2006 Posted July 20, 2006 I just setup 2 x 80GB Hitachi RAID 0 and I was wondering do the Hitachis come with SATAII enabled? If not, how do I enable them? Here are my results: Share this post Link to post Share on other sites More sharing options...
red930 Posted July 20, 2006 Posted July 20, 2006 I just setup 2 x 80GB Hitachi RAID 0 and I was wondering do the Hitachis come with SATAII enabled? If not, how do I enable them? You need to download the Hitachi Disk Tools application to enable SATA 3Gbps performance. Share this post Link to post Share on other sites More sharing options...
Liquidfire Posted July 21, 2006 Posted July 21, 2006 Can anyone answer my question from about 1/2 page up? What is better my increased read speeds on test ~1-5 with read caching on or my burst rate of almost 400 with read caching off? my pics are up there too what does read caching do? ive looked it up a bunch and havent found tons of info on what it does. Thanks again folks Share this post Link to post Share on other sites More sharing options...

Sorrento Posted July 21, 2006 Posted July 21, 2006 Nice boost... I don't like the way HD Tach measures bandwith... but it can show the Burst Speed, and there was a nice increase in performance with SATA2 enabled. Did you also enabled Spread Spectrum?
