I need some advice on replacing my existing 16 TB array (10x2TB RAIDZ2). I don't think I need a ton of storage so I'm looking at about 3x the storage (~50-60TB) and here is what I'm considering (serverpartdeals.com):

Size	Model	Type	Price	Price/tb	No. Drives	Total Price	Usuable storage (RAIDZ2)	Total price/tb
16TB	HC530	recertified	$157	$9.8/tb	5	$785	48 TB	$16.3/tb
18TB	X18	refurbished	$161	$8.9/tb	5	$805	54 TB	$14.9/tb
18TB	X20	recertified	$179	$9.9/tb	5	$895	54 TB	$16.5/tb
~~14TB~~	~~HC530~~	~~refurbished~~	~~$128~~	~~$9.1/tb~~	~~6~~	~~$768~~	~~56 TB~~	~~$13.7/tb~~
14TB	HC530	recertified	$144	$10.2/tb	6	$864	56 TB	$15.4/tb
16TB	HC550	recertified	$157	$9.8/tb	6	$942	64 TB	$14.7/tb

* 14TB HC530 only has only available in-stock.

I'd like to continue using ZFS (RAIDZ2) and if I understand correctly, expandable RAIDZ(2) is coming soon so I'm assuming I can expand in the future if needed.

Can anybody give me any advice?

I've never used enterprise drives before and I've also never purchased refurbished or recertified but it's a lot cheaper than buying new and/or WD RED, etc.

I'm also unsure the differences between Exos and Ultrastar but I think X18 is older and so is HC530. All the drives listed have a 2-year warranty which I guess is sufficient.

Don't choose Seagate if you value your data.

Decade old outdated advice with no context. 👎

Yeah, very outdated, just look at the Backblaze statistics every quarter 🤣

The overall failure for all these drives is so small that spending more money to lower failure rate by a negligible percentage is misguided and a waste of money.
