Re: Imports slower on my Windows PC than on my Big Sur Mac

My Win 10 PC has a 1TB Spinning Metal disk in addition to the 256GB SSD
So I thought I'd try for SM-HD versus SSD

On W10 SM-HD (seconds)
MP3:   17.6   18.3    18.0
WAV:   17.1   12.5    15.5
AAC:   11.5   10.8    17.2
But note my temp files and thus the project are on the SSD

On W10 SSD (seconds) - this is my earlier test
MP3:   18.6   16.5    16.1
WAV:   44.5   21.7    25.1
AAC:   26.7   12.9    18.2

So
a) a significant improvement with spinning metal for WAV
b) the initial export of each file-type is no longer slower than the
following two (a bit so for WAV)

The way I use this PC is that the 1TB HD is mainly used for less frequently
edited stuff, my photos
my iTunes libraries and my less frequently used files.

The SSD is used for all active Audacity work.  But maybe these tests
d=suggest that I may be better
off with active Audacity projects and possibly the Audacity temp files on
the HD.
