[dba-Tech] What's Better?

I agree that faster RPMs generally mean faster access.  In my experience,
the 5400 RPM drives are slower (usually in laptops) compared to a comparable
7200 RMP drive (in most desktops).  I am in the process of gathering the
parts for a new build and I just got the WD Velociraptor 10,000 RPM drive
because it is considered one of the fastest non-SCSI drives out there.

I've found that for Access work in particular rotation speed makes a
big difference. As you say there are other factors such as buffering
that factor into it too, but in most cases the faster rotation will
translate to faster transfer rate and faster seek times. As files get
fragmented the faster seek time will really make a difference. In my
opinion. I had a 10,000 rpm SCSI drive in one of my older systems -
until it croaked - and that baby screamed when doing Access work. I
really miss that.
