hi im about to complete my studio setup i just need to know how many hdd is best and what setup on each any ideas please help 

sorry i forgot to mention 5th drive external tb for backups of finished songs

yeah... more drives is OK.... but it's also so easy to add more.... if and when they are needed.

I started with 2 drives on a dedicated music computer.... no internet and no AV. I have not even come close to filling these drives and I write and compose a lot of music. 

drive 1 is for the OS and the programs.... 500GB in size. Since everything is music related, no junk programs, there is way more than enough room for everything. I also allow Cakewalk to store current projects there as well. 

Drive 2 is a 1TB storage drive. I keep all my samples on it and it also stores finished projects. I have 4 years worth of finished projects in numerous folders and it's nowhere close to being filled....it also stores the originals from downloaded programs and synths. 

I also use a 1TB external to mirror drive 2 and save original copies of downloads for software

I use other internet connected computers for surfing the net. 

thanks for the info

what drive do you recourd your audio to

I record into C drive.... the main one. 

C drive gives the fastest performance specs.... and I let it stay in the C drive in the projects folder for cake until I finish it. 

At that point I cut and copy to the 2012 folder which is also on the c drive desktop..... at the end of the year, I do house cleaning and move the 2012 folder to the second drive and copy it to the external and create new 2013 folder on the desktop. 

im confused because the only reasen im having multiple hdds is because i hered you have to have audio on its own hdd.

No.... it's not necessary.  

You can run it fine on one drive. 

I use the second drive to store the samples for my synths since the samples are audio and in wave form, they take up a very large amount of space..... so they go on a seperate drive along with the old files & project folders. 

I have been running like this for several years and for a few before that I ran it all on a laptop with one drive. 

By the time my storage drive fills up, I can add a new storage drive but likely the computer will have died by then and I'll have an even newer one with 2 TB drives.....

cheers that helps and saves me fxxxing around i guess.
