NAS Killer v4 Complete! (2019)

Just finished up my first server, an NK 4.0 build. I’ll be using the server mostly just for general NAS purposes as well as backing up a bunch of devices. Software/OS is not completely decided on, but after some convincing from JDM, I think I’m going to try and fit an unRAID license into my budget.

*These items were negotiated/offers were made. Those are not the usual prices.

So this build mostly revolved around the hard drives, which I’m sure you noticed were an amazing deal, which I got from a seller on r/homelabsales. The reason I was able to get 16TB worth of drives for only $110 was that the these Seagate drives actually seem to have been made for an OEM system, either a Hitachi or NetApp AMS. This meant that they were formatted differently, and the seller thought that they were 4kn. This meant that I had to get a newer SAS2308 card, the reason why I got the 9207-8i instead of one of the usual ones.

However, it turned out that the drives actually just had a sector size of 520, so it was a very simple command to format them to 512. Unfortunately, one of the drives had a mechanical error of some sort, something the seller said might happen since he wasn’t able to test them (he thought they were 4kn and didn’t have a compatible card). Luckily, I’ve started a return and a replacement drive is on the way.

Despite this small setback, overall I really enjoyed this build. I definitely learned a lot, and the community was very helpful in solving the (thankfully few) problems I had.

All of the parts I used I’d definitely recommend and I’ve had no trouble with thems o far. If anyone is curious about sellers I used and what offers they accept, or if you have any other questions, just ask.
