| Hello -I'm a developer and my firm is upgrading to a new server to house our DB. The new server has 6 drive bays, and I'd like to know how to optimized performance for our purposes.Currently, the option that seems to make intuitive sense to us is this:1x150gb system drive/tempdb1x150gb drive for transaction logs4x150gb data RAID 10 arrayThe # of reads dominates the # of writes into the data. One of the guys setting it up suggested a 6x150gb RAID 10 partitioned into 3 drives the first time around, and the second time around he suggested a 2x150gb RAID 1 for system drive/tempdb/transaction logs and a 4x150gb RAID 10 for the data.Which option is best? The 1/1/4 configuration for us seems to match better for our needs than both the 6 drive array and the 2/4 configuration, but we'd like to get some confirmation. Is there a better configuration? Thanks in advance. |

| That's probably the thing we're least clear on. Our understanding of it is that mirroring has a negative impact on write speeds, so is it just for the redundancy? And if opted for the RAID 1 transaction log drive for the benefit of redundancy, would it become the bottleneck during large writes into the data drive? |
