Hi All,

I just repartioned our SQL servers Data and Log partitions with the following to meet Microsofts recommendations:

NTFS Volume Serial Number :       0x2c3e7fc33e7f851c
Version :                         3.1
Number Sectors :                  0x000000018723bfff
Total Clusters :                  0x00000000030e477f
Free Clusters  :                  0x0000000002bd23c0
Total Reserved :                  0x00000000000000a8
Bytes Per Sector  :               512
Bytes Per Physical Sector :       <Not Supported>
Bytes Per Cluster :               65536
Bytes Per FileRecord Segment    : 1024
Clusters Per FileRecord Segment : 0
Mft Valid Data Length :           0x0000000002f00000
Mft Start Lcn  :                  0x000000000000c000
Mft2 Start Lcn :                  0x0000000000000001
Mft Zone Start :                  0x000000000000c000
Mft Zone End   :                  0x000000000000cca0
RM Identifier:        32383ED0-64E6-11E3-B58E-D8D3856289B5


Should i do this on the Index parition as well to help with performance.  Our database is quite large and we have seperated it to help performance and I just repartioned the Data and Log partitions based on that they were paritioned with Windows defaults (Bytes Per Cluster :  4096)

Also partioned the disks as primary partitions versus dynamic with hopes to increase the performance as well

Thank you for all of your help in advance

So this is SQL 2008 and server 2008?

No server 2003 or SQL 2003 involved at any point?

What type of RAID ,if any?
Controller model too.

The issue isn't so much with partitioning for speed,it's spindles.

Separate RAID spindles increases performance in SQL.

We are using raid 10 with 64K block size,

That is correct we are using Windows 2008R2 and SQL 2008R2
