I was wondering if someone could give me some advice on hard drives.

I currently have a Stock Western Digital 320GB 8MB Cache drive as my main drive in my mac pro and was wondering if this is ok?

I use my mac pro for logic pro mainly for pro studio work, and of course the usual internet etc...

I see that Seagate and WD now do 32mb cache drives and use perpendicular drive plates, Would these make a lot of difference to the speed of the OS? as they are both 7200 RPM?? or would only the 10,000 and 15,000 make a noticeable difference if any?

Many thanks :D

Most tests indicate 16 or 32 MB cache does not significantly improve drive performance over 8 MB.

10,000 RM drives perform comparably to 7200 RPM 750GB and 1TB drives.

15,000 RPM drive are mostly only available in SAS interface and are much more expensive than SATA drives.

Thanks for that, and the perpendicular technology that doesn't help at all?

Thanks

Perpendicular recording technology has no effect on performance at all, only on storage capacity. Using PR areal density is increased allowing more bits to be recorded in a given area.
