richardd43 Posted November 30, 2010 Share Posted November 30, 2010 I currently have 4 F40 drives in Raid 0. All drives were upgraded to firmware 2.0 and aligned using diskpart. After building the array the alignment shows as 103424 K When I installed W7 I did not do a format but used what I had from diskpart. Is that normal for a raid 0 array or did I do something wrong Link to comment Share on other sites More sharing options...

richardd43 Posted December 2, 2010 Author Share Posted December 2, 2010 Here is the ATTO run you asked for. I have also included the AS SSD run. It is the 103424 K number I am curious about. I checked a number of other forums and it looks like that might be the correct alignment for Raid 0. Link to comment Share on other sites More sharing options...
Synbios Posted December 2, 2010 Share Posted December 2, 2010 Your alignment depends on your allocation size. If your allocation size is 4096 for example then your alignment should be divisible by that. So post your allocation size. Also for RAID arrays you have to implement the stripe size as well in the calculation---try this calculator: http://www.techpowerup.com/articles/other/157 If you are using 4K, then your alignment is off, but your speed results look VERY good, right on par with 4xF80's in RAID 0 so I could be wrong.

Corsair Employees RAM GUY Posted December 2, 2010 Corsair Employees Share Posted December 2, 2010 It should be set to 128K stripe in the Raid and 4K Allocation if its the BOOT drive other wise I would suggest 32K allocation for the format.
