Does it all matter that much? Its not like HDDs differ all that much. Sure you have 5400rpm - 10.000rpm, different sizes, different platter capacity. But ultimately, every drive fails.
If you worry about drives failing, that implies that you are not using proper backups. Because if you do, you would care only about warranty period so your product gets refunded when it breaks. Your data will be safe either way.
Generally, i would get a single platter 500GB drive if you care about speed. Perhaps in a few years you would want an SSD to do the job for your system drive, though. And use HDDs only to store large (often unimportant) data.
I see your point. good reasoning!
