Mini-Mac Server as an NAS


Hi
I have been wanting to start digitalizing my music and placing it on a server.
I have a Mini Mac Server that I have been using for my business that I am replacing with a Windows Server (the programs we run are Windows based and the problems that we have had with the software to convert Macs to virtual Windows Machines have been so problematic that that they have almost closed us down). I was wondering about using the Mini Mac as a home NAS, since I would like to get some use out of it and since I otherwise have a Mac based system at home.
My main concern is this: I need about 4TB, and the Mini mac Server has 1 TB, configured as 2 500 MB drives in a RAID config. Can I add extra drives
and have them work seamlessly?

What I'm wondering is if the NAS software allows the pc to rip and store on the NAS without having to store it one the pc?
The ripping program should allow the target drive to be selected from among all drives that can be seen by the operating system, including a NAS drive.

And also be careful that there are new disks that are being sold now that use 4K physical sector sizes and use software in the drive to do 512 byte sector emulation for the O/S. Stay away from them. And I believe there are some type of "hybrid" drives out that have 4K sectors and somewhat large solid state caches to help overcome the performance degradation of 512 byte emulation when using physical 4K sectors. Stay away from them also.
These are what are often referred to as "Advanced Format" drives, which are becoming increasingly prevalent among large capacity drives. The issue is that if partitions aren't aligned with the 4K sector boundaries, speed may be compromised. However,

1)Mac os's from Tiger onward, as well as Windows Vista and Windows 7 under most circumstances (i.e., if a cloning utility is not used), will correctly align the partitions when the drive is formatted, without doing anything special.

2)Western Digital provides an alignment utility for use with Windows XP and other older os's (see the links below).

3)In a NAS or other external drive application, the speed compromise that would result from misalignment is likely to be nil, because read and write speeds will be limited by the network interface (unless it is a wired gigabit ethernet connection), as well as by the cd drive during ripping, and by the audio data rate during playback, not by the hard drives in the NAS.

See the following for additional information:

I'll add that I recently installed an external (USB) Western Digital advanced format drive on a Windows XP system, without using the alignment utility, and its speed as measured with HD Tune was as good as I would expect from any USB-connected drive.

I should have mentioned in this statement that prior to performing the speed measurement I had re-formatted the drive into multiple partitions, using Windows XP, which defeats the alignment the drive was originally supplied with, and supposedly makes it necessary to use the WD alignment utility. But no speed compromise resulted, even though I didn't use the utility.
