PC/Windows I/O problem?
Looking for a bit of advice. I have a high-spec PC with Windows 10 Pro installed. All satisfactory except for accessing HDDs. In Windows Explorer, it sometimes takes more than a second to open up a folder or to show the content of another drive - which seems awfully slow compared to other machines (and this is after switching off power-saving features that might take a while to wake up a device when it hasn't been used recently). Writing to the HDDs equally feels slow. There are 5 drives attached, 4 HDD and 1 SSD - the HDDs are pretty average WD Blue or Red devices. Accessing the SSD, probably not surprisingly, is faster. I wondered whether having this number of disks may be causing the problem.
I've had a quick look around for tools to evaluate I/O performance but nothing jumps out at me so I thought I'd ask here for views. Does any kind soul who knows how Windows works have any idea whether having lots of drives attached slows things down, or have any other suggestions or pointers as to why I my machine might be a bit sluggish in this area?
Many TIA.
