I was about to buy a NAS. I find the idea of using an old laptop instead interesting. Especially since it comes with UPS built in. The author is using a ThinkPad T430. Any experiences?

I see a lot of people using M710 mini desktops - I think you can pop a pcie 10gbe card in and a m.2 SATA card and 3d print a disk stand?

I've been considering "de-enterprising" my home storage stack to save power and noise and gain something a bit more modular. Currently I'm running on an old NAS 1U machine that I bought on eBay for about $300, with a raidz2 of 12x 18TB drives. I have yet to find a good way to get nearly that much storage without going enterprise or spending an absolute fortune. I'm always interested in these DIY NAS builds, but they…

2U is definitely better, but I didn’t notice significant drops in dB till I could stuff a 120mm fan in the case. That requires a 3U or more.

And if you need a good fan that’s quiet enough for the CPU, you’re looking at 4U. Otherwise, you’ll need AIOs hooked up to the aforementioned 120s.

For me it was important to have ECC RAM and laptops pretty much never have that. My personal recommendation is an old IBM/Lenovo workstation tower as the base. I bought one for $35 on eBay and added $40 of RAM (32GB). A $10 UPS from Goodwill with a $25 battery from Amazon, and whatever hard drives you want. I run Ubuntu and ZFS on it but next time would probably opt for FreeBSD for a nicer OS.

Why is it important for an NAS to have ECC RAM?

I own this and it's worth it's weight in gold https://www.supermicro.com/en/products/motherboard/A2SDi-H-T... Yes. It's pricey but it's never been a problem. It can connect like 12 HDDs with 256GB ram and has 10GBe and runs at a tiny TDP. Has IPMI. Fits in a tiny case. The only issue I had with this motherboard was that it was difficult to find someone who sold it. Love it Also I don't see the built-in UPS. The exter…

Wow. It even has ECC!

Uhh could you provide a hook for such a deal? I've been starving for more storage and can now handle a rack mounted system but have been avoiding dropping $1000 on a pair of new hard drives.

I just missed an ebay opportunity to get a dell r730xd with 12x 12tb drives for around 400 dollars.

if you're willing to wait and bid-snipe you can find deals like that routinely; just wait to find one with the size drives you want.

if you just need the drives similar lot sales are available for high power-on time zero errors enterprise drives. I bought a lot of 6x 6tb drives two weeks ago for 120 usd and they all worked fine. If you have the bay space and a software solutuon that lets you swap them in and out as needed without distorting data then there is a lot of 'hobby fun' to be had with managing a storage rack.

Earlier quoted context omitted.

I would also prefer having a large number of high capacity SSDs so I could replace my spinning hard drives. But even the cheapest high capacity SSD deals are still a lot more expensive than hard drive array. I’ll continue replacing failing hard drives for a few more years. For me that has meant zero replacements over a decade, though I planned for a 5% annual failure rate and have a spare drive in the case ready to g…

You can find cheap used enterprise SSDs on ebay. But the problem is that even the most power efficient enterprise SSD (SATA) idle at like 1w. And given the smaller capacities, you need many more to match a hard drive. In the end HDD might actually consume less power than an all flash array + controllers if you need a large capacity.

Used SSDs, especially enterprise ones, are a really bad idea unless you get some really old SLC parts. Flash wears out in a very obvious way that HDDs don't, and keep in mind that enterprise-rated SSDs are deliberately rated to sacrifice retention for endurance.

What exactly are these "white label drives"? Aren't these just normal seagate exos drives with SMART information wiped and labels removed? i.e. just a worse used drive.

Apparently Seagate drives that weren't good enough to have their own name on them... which given the history of even their branded drives, is something I'd only use for temporary caching of data that's easily regenerated.

Used a Lenovo X220T with a cracked screen and missing keyboard a few years back. Worked like a champ (as a server). Cooling was much better without the keyboard.
