z.nina - Well that isn't any last century drive - looks like a WD20EZRX or immediate predecessor, 64MB cache is industry standard on current model desktop drives.
I wouldn't be surprised if that drive wasn't still under warranty, so if it has serious problems WD would replace it. I just checked a Caviar Black I bought last year, its warranty is good up to July 2017.
Did you get a chance to try with the library on your USB3 external drive - as I said I would expect calibre to fly. I'd really like to know that before suggesting anything else.
If it shows the same slowness when exiting a Metadata Edit, then there's probably no mileage in looking for BIOS drive configurations, running diagnostics, looking at event logs or reformatting drives.
Also, without having the BIOS in front of me it's hard to tell you how to determine if the drive is precisely configured. But as its SATA that eliminates Katsumi's concern regarding old IDE modes. And if other programs and data are OK then its probably AHCI too, so lets put that avenue of enquiry aside for now.
I'll put together some screen shots for setting that Environment variable. Because that's what I'm going to suggest you do if calibre doesn't fly on the external USB3 drive.
