This 10k rpm drive will enrich your sound around 5.000 Hz!!! (The Nyquist frequency)
Usually old SCSI-drives (and 9GB sounds like the capacity of an old hard drive) make a lot of noise.
You should put the drive outside the sampler to have the option to switch it off, if it's too noisy.
There are no advantages or extra power to gain by using such a drive.
