robinlawrie Posted October 24, 2009 Share Posted October 24, 2009 ok, bit of a long post. i have 2x p128's in raid 0 (intel raid controller)on the a gigabyte ga-ex58-ud5 these are used as my system drive and backed up on a 1tb hdd. i have windows 7 rc x64 due to win7 not installing properly on sata raid arrays (is this fixed in the released version?) i had to install on one drive then migrate to the other drive using matrix storage manager.. this worked perfectly. when i first installed i was getting hdtach scores in the high 400's (not a suitable benchmark i know, but..) yesterday i think i knocked the sata cable to one drive whilst it was running. this completely killed the raid volume, and i had to re-install.. due (i assume) to the raid problem with win 7 installs, my disk image of win7 wouldnt reinstall, whatever i tried. i re installed using one drive, then tried to migrate to the other drive. i got an error saying that the drive i was trying to expand onto was smaller. i tried EVERYTHING i could think of.. finally i found out about hdderase, and ran it on the empty ssd. the raid array then migrated fine, and im back up and running. (128kb stripe) HOWEVER.. my windows experience score was lower, so i ran hdtach again, and im now only getting average hdtach read speeds of 230 mb/sec.. this is close to a single drive so what the hell is up and how can i fix it? please heelp i use this drive for hd editing also so the performance really matters.

robinlawrie Posted October 24, 2009 Author Share Posted October 24, 2009 crystal disk mark scores for the current setup: 357.8_215.2 270.3_153.5 25.48_9.493 do those scores look normal for a dual p128 raid setup? i didnt run it before the catastophe you see. the 4kb random reads and writes look terrible to me? i know its a weak spot of ssd's but still... 9mb/sec?!?

robinlawrie Posted October 24, 2009 Author Share Posted October 24, 2009 attached (i think) atto screengrab.. the identical setup is tested here: http://www.corsair.com/systembuild/report.aspx?report_id=1084686&sid=7 with significantly better results...

robinlawrie Posted October 24, 2009 Author Share Posted October 24, 2009 hmm the file upload fails on any filetype i try... small file too. ok well the read speeds in atto are relatively similar to the ones i linked, but the write speeds are significantly slower, maxing out around 220 meg / sec Link to comment Share on other sites More sharing options...
Thorsten_de Posted October 24, 2009 Share Posted October 24, 2009 Hello together! I use 2 P128 VBM18C1Q in Raid0 with an Intel IHC9. I'm angry because it looks that the GC doesn't work in a Raid0 configuration. :mad: My write performance has lost around 50% in one Month. :eek: Greetings, Thorsten.

JohntechUSA Posted October 30, 2009 Share Posted October 30, 2009 You should be able to install the Raid aray driver durring the install of Windows 7 by using the F6 Key when the setup first starts. If this si not working or the driver is not working you may need to get an updated BIOS or driver from the MB Maker. I would try and copy the image using Accronics Drive image and the use the Gparted method to delete the partition and whipe it. Then recreate it with 128K Clusters in the Rad and 32K Allocation for the format and test the drive before you load the O.S. Link to comment Share on other sites More sharing options...
Dusan123456 Posted October 30, 2009 Share Posted October 30, 2009 I had the same problem trying to install my image on a RAID 0 with two P128s,using an Acronis 2009 boot disk. The problem was solved when I download the multiparameter boot disk from the Acronis web site..it apparently can recognize the RAID 0 with two SSDs. I use Win 7 Pro and haven't seen a performance drop I can notice,but within hours the Windows experience score dropped from 7.3 to 5.9. Had a problem installing the Win 7 on this array as well,until I removed each drive and "pre-formatted " them,after that Win 7 could see the array Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 31, 2009 Corsair Employees Share Posted October 31, 2009 I would suggest using the latest Version of Accronnic's I had some issues with the release version of Windows 7 till I went and updated to Accronic's Home 2010.
