Re: wiping SMART, apparently they don't but occasionally the manufacturer does.
either way, yes to redundancy but I doubt they would offer a two year warranty on potentially flawed products.

Considering it's 60tb and rebuild is a very slow process (it does not go at the max write speed of the drive) it can take days, even weeks for the drive to rebuild - because it is recalculating all the parity, keeping track of ongoing changes, rebuilding the new changes, balancing the data across drives etc… so if the rebuild runs for a week, and you get another drive failure, or a read error in any of the drives (keep in mind these are refurb so there is a small change of this) your entire raid 5 is lost… good luck with recovery…
Raid 6 or raid z2 is more dependable if you must, as it can tolerate 2 drive failure, but will slow things down - if this is for home use it wouldn't matter a whole lot.

**NOTE: While poor reliability on one storage tier does not mean poor reliability on another, it does give me pause.**
Personally, I'd buy direct through Server Part Deals as opposed to through their eBay store front. For an extra $13 (a little more than three cents a day), you're getting an extra year of warranty coverage—seems like a no-brainer.

Here's Backblaze's collection of drive data where they have actual sample sizes large enough to learn from (spoiler, for actual large sample sizes, the failure rate is 1-3%> no matter which manufacturer you have so it's just a roll of the dice if you have bad luck):

If you're filling drives with multiple terabytes of important content, you need to be using some form of redundancy and following the 321 method of backup. If you're just storing replaceable media, then screw it, get the cheapest $/tb deal you can as long as it has some form of warranty so you can get your money's worth.
