[Update] A recent question about upgrading my iMac desktop

The previous post is here.

What a strange turn of events! Also, I'd like to thank everyone that replied in the previous thread. You all are so very well informed and helpful!

I was preparing to make the transition from my current iMac to the one suggested here. I have 2 external hard drives. One of them is a 6 TB drive that is used for backups. The other is a 500 GB drive that I use for media storage. I bought this media storage drive around 5 years ago so the official site, probably, isn't up to current specs.

To explain more, I moved all of the media files from that 500 GB external drive back to my iMac since it supports 1 TB of storage. No problem there and I still have plenty of additional storage.

Slowly I began to notice that my iMac was responding a little faster for some things. Intuitively, I decided to 'eject' the 500 GB external hard drive and physically unplug it from my iMac.

After I did this, my iMac began responding to anything with lightning speeds! I guess this problem is solved and I have no idea what may have caused this in the first place.

    Perhaps there was a connection issue or drive failure that resulted in performance hits when trying to read/write data. Like OS tries to write file, drive doesn't confirm write, so OS tries again.

    This sort of thing definitely happens if there's connectivity issues between a SAN and a server, so it seems plausible that the same could happen on an external HD.

      Worth adding explicitly that this is a reasonably good sign that you should stop using that drive entirely - if it's causing weird errors and slowdowns now, there's a strong chance it'll fail...

        Right. As soon as I got all my data off of it I threw it in the bin.

    Did you have photos on that external drive? It's possible your mac was trying to index them for the iCloud photo library but something like a bad sector or some sort of formatting issue kept it...

    Did you have photos on that external drive? It's possible your mac was trying to index them for the iCloud photo library but something like a bad sector or some sort of formatting issue kept it from being able to complete the index so it just kept trying over and over again.

      Yes and I think you're spot on.
