Mac Pro boot HD Query

[npj]

Hi all,

Does anyone know what the difference in performance would be for these HD's (for the boot drive) in a Mac Pro...

A) Seagate 7200rpm SATA HD (320GB, stock w/Mac Pro early 2008)
B) Seagate 15,000rpm Cheetah HD (ST3300655SS Cheetah 15K.5 SAS 3Gb/s 300-GB Hard Drive - ST3300655SS | Seagate) (Need a RAID card but that's no problem)

The 15k drive is obviously faster but how much difference does is make practically? How much faster would the computer actually feel? Would it be able to process quicker with a faster HD? I'll be using it for audio work.

Thanks

What type of Audio work are you doing?
Personally I wouldn't have the boot drive as my main data storage/manipulation drive. I would just leave the 320GB stock drive as the boot drive and possibly use the SAS drive as the audio storage/manipulation drive.
If I were in your position I would just use an SSD as the boot drive, then set up a striped raid of regular SATA drives as my data area.

It'll be doing a lot of sequencing with Digital Performer. Mostly softsynths, some audio.

Long story short, I've just got a refurbished MP and it came with two of those 15k Seagates plus a raid card! So I don't actually have a 7200rpm HD at the moment. I'm could get one to use as the boot HD if using one of the 15k HD's is a waste.

What do you think?
