red930 Posted August 4, 2005 Posted August 4, 2005 Yeah, to get a quality RAID-5 array going you really have to invest in a quality controller first. After that the drives are almost secondary. Ohh well looks like I wont spend the money on additional HDDs to go RAID5... Share this post Link to post Share on other sites More sharing options...
Guest cloud_171 Posted August 6, 2005 Posted August 6, 2005 Think selling my raptor and putting in some money for 4x hitachi sata II worth it? Share this post Link to post Share on other sites More sharing options...
Smoken Joe Posted August 6, 2005 Posted August 6, 2005 Think selling my raptor and putting in some money for 4x hitachi sata II worth it? Single raptor. Yes I would switch to 4 Hitachis if you can get any decent amount of mony for the raptor. Share this post Link to post Share on other sites More sharing options...
Vektor Posted August 6, 2005 Posted August 6, 2005 What about x1 drive? Share this post Link to post Share on other sites More sharing options...
soundx98 Posted August 6, 2005 Posted August 6, 2005 lot to be said for a 4xHitachi SATA II drive setup course, you won't do any whining with 2x Raptors either. Share this post Link to post Share on other sites More sharing options...
red930 Posted August 6, 2005 Posted August 6, 2005 The WD Raptors are incredible drives. The 10,000RPM spindle gets the data under the heads faster than any 7,200RPM drive could ever accomplish. This leads to virtually unbeatable access times. On the other hand they are quite expensive and run very hot. A single 74GB Raptor with SATA 150 runs about $155.00USD. Two Hitachi 80GB SATA II drives will run about $110.00USD. For about 70% the cost of a single Raptor, you've got the two drives necessary for a RAID-0 array that will provide 9/10ths the performance of a Raptor array that would cost over $300.00. The Raptor array would be a tick faster than the Hitachi array but cost almost 3 times more for that small performance increase. Take a look at my sig for Aileen and see which way I went.

catkicker Posted August 6, 2005 Posted August 6, 2005 Well with the new raid system up I followed some advice and durring OS install I created a 10Gig partition for later use. Today I moved my pagefile to D: the 10 Gig partition. Cluster time next Share this post Link to post Share on other sites More sharing options...
catkicker Posted August 7, 2005 Posted August 7, 2005 Ok heres what i get with the seagate Satas I setup stripping at 16k I thought that was reccomended to me but I lost the printout of directions I have not setup cluster size. Wondering if I need to redo array and change to 64k stripping. Guess with 16k I need to go with 4 on cluster, is that the way I understand it.

ncsa Posted August 7, 2005 Posted August 7, 2005 They are looking good....there is definately something about running 4 drives What are your HD Tach burst and average read results? What I found was that I had to try various combinations to find the best working configuration for my hardware and keeping the 4:1 Ratio in mind (thxs to ExRoadie for getting it right in my head) and this is what I am now running. See post here. Ok heres what i get with the seagate Satas I setup stripping at 16k I thought that was reccomended to me but I lost the printout of directions I have not setup cluster size.

catkicker Posted August 7, 2005 Posted August 7, 2005 4 X 80GB. Seagate Satas Nvidia RAID-0 16k & 4 Share this post Link to post Share on other sites More sharing options...
red930 Posted August 7, 2005 Posted August 7, 2005 Looks like the four drives scale nicely. One thing you will notice when comparing 1.5 to 3.0Gbps SATA II drives it the burst performance. Even with a lowly 8MB cache The high speed SATA II drives provide twice the burst performance. This is an example of where the higher bandwidth available with 3.0Gbps lets the cache really shine. Just imagine when Hitachi starts putting a 16MB cache in their drives. Devastating! 4 X 80GB.

catkicker Posted August 7, 2005 Posted August 7, 2005 Right now all partitions are set the same 16k & 4 As I recall you mentioned different cluster size for the pagefile partition, should I change cluster sizes? Share this post Link to post Share on other sites More sharing options...
