Moving from EXP400 to DS4300

Hello! We are moving our database from our SCSI-based EXP400 to a new DS4300. Today we have it setup like this. 2 73GB 15k (raid 1) for OS (located in the database server)
2 73GB 15k (raid 1) for system databases including tempdb (located in the database server)
2 73GB 15k (raid 1) for userDB logs (located in the database server)
10 73GB 15k (raid 10) for userDB (located in EXP400) The new setup will probably be 2 73GB 10k SAS (raid 1) for OS (located in the database server)
2 73GB 10k FC-disk (raid 1) for system databases including tempdb (located in DS4300)
2 73GB 10k FC-disk (raid 1) for userDB logs (located in DS4300)
10 73GB 10k FC-disk (raid 10) for userDB (located in DS4300) Is there any reason to change anything in this setup?
I was thinking it might be better to use all 14 disks (raid 10) for a single array and place userDB/logs and systems dbs there? (probably not but, anyway) We have filled the DS4300 with 2 HBA and 2 SFPs

I would like to know why you will go with 10K instead 15K?

The short answer: I dont want to <img src=’/community/emoticons/emotion-1.gif’ alt=’

‘ /><br /><br />The reason why we choosed 10k disks is because of money, and the fact that we dont have any performance issues with our current setting. If we need more performance then we can just add a EXP710 to the SAN and add more disks to the array. But today the price difference between 10k and 15k was to big. <br />We also have the possibility to purchase the turbo settings for the SAN wich could improve the performance, when we need it.
