Hello, I’m relatively new to self-hosting and recently started using Unraid, which I find fantastic! I’m now considering upgrading my storage capacity by purchasing either an 8TB or 10TB hard drive. I’m exploring both new and used options to find the best deal. However, I’ve noticed that prices vary based on the specific category of hard drive (e.g., Seagate’s IronWolf for NAS or Firecuda for gaming). I’m unsure about the significance of these different categories. Would using a gaming or surveillance hard drive impact the performance of my NAS setup?
Thanks for any tips and clarifications! 🌻
As you are looking for bulk data storage, the drive’s speed isn’t of too much concern. A 5400RPM drive is plenty.
If you are looking to put this drive into an array with other drives, make sure you get a CMR drive as SMR drives can drop out of arrays due to controllers finding them unresponsive. If a drive does not list it is CMR, it’s best to assume it isn’t. Seagate has a handy CMR chart, for example.
Additionally, if there are multiple spinning drives in the same enclosure, getting drives with vibration resistance is a good bonus. Most drives listed for NAS use will have this extra vibration resistance.
Is this for hardware RAID controllers, or have you experience software RAID like LVM or ZFS exhibiting the same drop out behavior? I personally haven’t but it be nice to look out for future drives.
I have not personally experienced a dropout with a SMR drive. That is from the reporting I saw when WD was shipping out SMR drives in their Red (NAS) lineup and people were having all kinds of issues with them. According to the article (below), it sounds like ZFS has the worst time with them. WD also lost a class action suit over marketing these as NAS drives, while failing to disclose they were SMR drives (which don’t work well in a NAS).
Right, I did hear about that lawsuit way back when, I just didn’t know of these types of consequences. Very appreciated, especially the sources.
I remember this - I had just bought my second drive for my nas (raid1, original drive cmr), and it was performing like shit. The next day, news broke about this bullshit and a couple days later, the suit was started. I was fucking pissed, the drives were still having trouble, with terabytes of irreplaceable data at risk while the two drives struggled to mirror. I got in contact with wd and after some back and forth bullshit, I straight-up threatened to join the class and blacklist wd for all my personal, family/friends, and client’s builds, if they didn’t rma the drive immediately and send me a cmr replacement. I’ve been 100% wd for over 20 years, and I have decent reach as to what I recommend and buy for people.
They sent me a cmr drive via express shipping. I continue to buy wd drives (two more disks in that machine, an external backup, an internal desktop pcie raid0 nvme+card, an internal backup drive for my desktop, another backup ssd for one of my laptops…), but with much more scrutiny. I did not join the class, but it’s still a black mark in my book. I’ve been thinking about giving Toshiba a whirl, their drive reviews look good. Maybe next upgrade…
Purely for my edification, why didn’t you join the class action? It’s not like you weren’t affected or even that they had any redeeming behavior.
Thanks for this, will read up and check out the links!
