GP was likely confused by the different types of hard drives (standard, sc1, st1), and assumed it was tape or was incorrectly told by someone else that it was tape.
If I squint hard enough, the only viable explanation I could come up with is GP said "I created the database using the st1 storage type" and someone responded "st!? As in a UNIX SCSI tape drive[0]?"
It could be tape. But perhaps you’re right that it’s HDDs I guess? I assumed most of their normal storage is hard disk and not SSD. They’ve got a lot.
Edit: I checked. You’re 100% right. Well now my anecdote sucks! :) And now, seven years later, I’m back to start on wondering why it was so brutally slow.
If you provisioned a really small amount of GP2, you can run out of I/O credits pretty quickly and get throttled to baseline performance (and it used to be 7 times the storage provisioned, or some such, and now it's 100 IOPS). That's brutally slow for a working database.
