Hey all you beautiful selfhosters,
What are your suggestions for frugally obtaining HDDs in the current economic climate? Specifically the EU (Netherlands).
I’m looking at second hand drives, but even those go for €100+ now, with bad sectors and all.
Can we organise a collective AI datacenter robbery and doll out some stolen drives? 😁
Frugally (legally) obtained HDDs are still going to cost you a lot of money, there is no way around that at the moment. If you need it, pay up and be done with it. If you just kind of want it, start sorting through your piles of data you don’t actually need (yes, you have that, stop lying to yourself) to free up space for things you do actually need.
True, but it’ll be nice to have enough space to let the future arr stack I plan on spinning up, roam free
So is there a raid 12 for my 13 500GB drives?
Don’t forget the power bill, even if they sit idle most of the time. 12 drives * 5 watts * 24 hours * 365.25 days ~= 525 kwh. That would cost me $157 aud a year for electricity.
If I instead bought a 6TB drive brand new I’d break even after 3 years, assuming the 500GB drives are $0.
Yeah, it’s half joke, half backup territory (so the drives could just be offline mostly).
RAIDz2 for 5.5TB with 2-disk redundancy.
All of a sudden USB becomes important. 😅
https://datablocks.dev/ is a Dutch company.
Amazing! Thanks
It looks like good prices. But every single one is out of stock
I see 14 SKUs in stock. They explain how they get stock, just need to be patient.
That said, OP is asking for something around 100 EUR which is pretty low and not many enterprises or SMBs will buy drives that small. That just sucks if you need something like 4Tb.
They have good deals on 10+ Tb drives tho.
Frugal and recycled. Using a mix of old disks in OMV8 with a mergerfs array, suprisingly they amounted to 20TB, so saved a few bob.
If a disk fails in Mergerfs you loose the data on that disk only and not the array as you would with a pure jbod array.
There is a remove disk utility in the OMV8 mergerfs plugin that allows the data from a failing disk to be copied back to the array, if enough space is available, retaining the data from the failing disk. The disk can then be physically removed. If the array is short on space, add a disk to expand the array before removing the failing disk.
I’ve only ever used it with a failing disk, not a failed disk, I would guess that a backup would be required in that case.
The same applies to mergerfs outside of OMV8, this was easier for me.
I use snapraid for parity on top (OMV7). Works nicely with mergerfs. If a drive fails it can be easily rebuilt. You can use older smaller drives to do split parity (I got 3x 8TB as array and 2x 4TB for parity)
I still have some IOMEGA Zip drives. LOL Man, I remember when those seemed inexhaustible.
Honestly, I’ve been taking a chance on eBay. If the price is close to $10/TB and the drive is an enterprise drive that is listed as known to be working, with a good return policy, I take the risk. I just run tests as soon as I have it so far, all have been good (eight purchases).
I usually scavenge old drives from work. On one hand they’re a bit smaller than I’d like them to be, but on the other hand they’re free except from the minor work and documentation involved in ensuring that no company related data remain.
Wish my company allowed that. Everything goes to a licensed secure destruction service that literally puts them through an industrial shredder. Awesome to watch, but wasteful as all hell.
Well, there’s a footnote on my end: Me taking the drives home is a bit of a grey area, as the procedures say that the drives are to be mechanically destroyed when no longer needed. It doesn’t specify needed by whom. And I do attack them with my angle grinder, so it’s in accordance with company policy.
And yes, my employer knows and is OK with it. We go through a ridiculous amount of drives due to large storage needs, so pragmatism tends to trump bureaucracy.
Also true for me
I’ve had good success buying second hand on eBay, but I bet you could also do worse than getting used parts off Gumtree, look for anyone selling a broken or outdated computer - or in the free section - and spend some time going through a pile of ewaste, shucking all the drives, and then running tests on them.
My work sells commercial tier drives that were used by customers in NVRs for $10/TB. It’s honestly a great perk of the job for a data hoarder like myself with a fully redundant 100TB of stuff (aka 200TB of drives). I also got a dope 16 bay server chassis with slides and a few other components from them. I fully intend to drop like 2 grand on HDDs if/when I move to a new company, assuming they don’t fire me for AI or something first.
Well let’s start with how much you need.
Then we can all cry. Currently looking at replacing HDDs with SSDs and significantly cutting down on my data storage requirements - basically uninstalling all those games I haven’t played in a long time and probably won’t. Plus it’s easier to avoid getting sucked into playing ESO and wasting money on it if it’s behind a 100+ GB download. Majority of games I actually play are under 5GB so I could go pretty heavy. Couple second hand 512GB SSDs perhaps? Under £100…
I reckon I need about 10TB of RAID 1 for a decent Jellyfin media server
I have a 2tb ssd for my media server. I haven’t filled it yet, but I do sometimes delete things. Don’t tell anyone.
Get lucky - just as this was starting I saw a failed disk notification on my NAS so I ordered a new drive just before they went up. Then I realized it was a stale notification for the drive I replaced a year ago so I have a spare should one fail.
There was someone here not too long ago who purchases HDD with bad sectors. I think the idea was to instruct Linux to not use the bad sectors. I am unclear about the mechanics of how it’s done, but the concept has been rolling around in my head ever since. The drives in question were purchased knowingly with bad sectors and came with a warranty.
When a drive has bad sectors, the rest of the drive will likely also be near EOL…
I thought the same thing, but whomever the chap was, was buying 15 TB+ drives and didn’t seem to have issue. I questioned him about exactly what you said, and again, they didn’t seem worried about putting over 15 TB of data long term, on a drive that had bad sectors. The reason it came up, was because I was scrolling through New Egg and came upon some relatively cheap drives, however the seller was upfront about there being at least 25 bad sectors. I asked ‘Who would buy such a thing?’ and that’s how the convo started. I’ll have to go back through my comments and see if I can find it.
I picked up enough used SAS drives to build an 11 drive RaidZ3 pool. 100 USD each shipped. DIF formatted so had to low level format to native 4k sectors, then run a full run of badblocks, and finally a long smart test to verify no errors. Had a couple bad drives that the seller replaced no questions asked when I provided the smart logs.
SAS controller and backplane opens up a lot of drives that SATA controllers can’t touch.
My old pool drives will be repurposed for a FrigateNVR storage point and a storage point for some other stuff as well as spares for other pools.
Enterprise decommissions, workplace, stuff ehere they just want to get rid of it quick
Vinted has some nice deals every so often.
But look at German sites for better HDD deals then NL.Any recommendations?
Have you tried Tweakers Vraag & Aanbod yet?
Yeah, I have it opening every morning to see if there are any new ads
