Higher RPM hard drive questions

[vanguns]

I'm thinking about purchasing a higher RPM hard drive, but there ar
two issues I'm considering

1.) Does a higher RPM make a noticeable difference in startin
programs and running the OS? (most of my data will be on a larger
slower drive)

2.) Is there any extra noise associated with a higher RPM drive

Anyone have some experience with this and can help me out

I'm thinking about purchasing a higher RPM hard drive,

Higher than what ?

but there are two issues I'm considering:

1.) Does a higher RPM make a noticeable difference
in starting programs and running the OS?

The boot time is usually improved. Starting programs, not that much.

(most of my data will be on a larger, slower drive).

2.) Is there any extra noise associated with a higher RPM drive?

Depends on what you mean by higher RPM. The
Samsung 7200 RPM drives are essentially silent.

1. Noticeable, but barely so. My 10K RPM SATA HD has a random access
time of 8.0 ms; my 7200 RPM SATA HD has 13.8 ms. Both with HDtach.

2. Not for me. But then, I can't hear either of the above HDs over the
sound of the seven fans in this PC's case.

I expect you have to go to 15.000 RPM to notice the difference without
a stop-watch (assuming the comparison is 7200 RPM). High RPM is most
beneficial for random access, e.g. in databases. Program start is
more linear reads and high RPM does not do much for that (if at all),
since data density on high RPM drives tends to be lower and many are
actually 2.5" disks, giving them shorter tracks on average.

2.) Is there any extra noise associated with a higher RPM drive?

Yes. But it has gotten better. Look into the datasheets and for
tests on the Internet. There is also likely a need for more cooling.

But not half that of 7200.

Any simpleton can go to Storage Review and see that SCSI is nearing
100MB/s.

Yes, 10K is noticably faster than 7.2K for the OS.

Nonsense, program loading is mostly random IO.
