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 | 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Decade old outdated advice with no context.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Yeah, very outdated, just look at the Backblaze statistics every quarter 🤣
Which covers only a small quantity of batches of drives 🤔
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.
All your options are within ±$150 of each other: so I’d grab the largest-usable config. If it also happens to be the lowest $/TB… that’s gravy. Pay those few extra dollars now and it may let the new setup run a couple extra years before it doesn’t meet your needs anymore.
I don’t stress over brand/model: parity configs take care of availability, and automated 321 backups take care of recoverability. Disks are consumables: any one of them could fail tomorrow: but you data should be immortal :)
If I’m buying new I’ll look at $/TB/years-of-warranty, but for refurbs you’re lucky to get a couple months so that doesn’t really sway my decision.
Enjoy all your new space!
raidz expansion has been coming soon since 2019, at least it has support from ixsystems now but still not holding my breath, and i want the feature to expand mine.
Stop being lazy and just use punch cards like a real horder.

It’s been coming soon for years now lol
Here’s a post on drive testing to do on the drives
would be so much easier if you were using unraid :)
