/rant on (with apologies, but this video was a bit egregious)
So, @Joon posted a Linus TechTips youtube link, where Linus allegedly rips the Jellyfish from OWC to shreds using TrueNAS, etc. Some observations:
For someone who consistently tries to needle folk for spending too much money for allegedly overpriced solutions (i.e. Jellyfish), Linus is remarkably off the mark in this video re: what would make a sensible case, SLOG, and power supply selection.

So, @Joon posted a Linus TechTips youtube link, where Linus allegedly rips the Jellyfish from OWC to shreds using TrueNAS, etc. Some observations:
- It's very odd to be using a cheaply-built $950 iStar case for a production server. I'd argue that a used SuperMicro 846 with dual PSUs ($400 on eBay) would perform better at a much lower cost.
- The two-supply-in-a-ATX case is a neat engineering solution to a problem that the 846 doesn't have. @jgreco's likely would take issue when Linus proudly trots out a Twins Pro 700W, allegedly redundant, PSU for a 24-drive (20HDD, 4 SSD) server. Per @jgrecos guide, the peak load can max out both PSU's, eliminating their redundancy...
- I'd prefer the SuperMicro 846-included dual 80+ Gold 1,200W PSUs simply on the basis of wider availability on the new and used market.
- Want a higher-efficiency PSU than the 80+ Gold offered by the Twins or the stock SM PSU? No problem, you can buy two new 1,200W PSUs directly from SuperMicro that are Titanium rated and still spend less than Linus did for the Twins Pro 700W ATX assembly.
- Plus, the Supermicro PSU and case actually features a good backplane design that plugs straight into their PSU as opposed to the Octopus-fest that Linus seems to be enjoying with iStar in the video.
- The fan choices also just make me shake my head. There is a reason that iStar isn't on my buy list and the stock fans inside the SuperMicro actually prevent the HDDs + CPU from stewing in their own juices.
- The HDD choices seem solid. He drives are a great choice for something as dense as that server.
- The Sabrent 2TB NVME choice for a SLOG is pretty confusing considering the likely performance of same. The capacity way exceeds what he needs for a SLOG. With all the money one saves buying a used 846 case with its PSUs ($1,100) and the Sabrent 2TB drive ($429) one would be able to put in a $1,300 375GB p4801x and really go to town. Adding a second SLOG in a mirror would make sense, however.
- The board, CPU, 2TB L2ARC for a 256GB RAM / 244TB Pool seems about right also.
- The LSI 9305-16i is a good choice for an HBA.
- A boot pool with 240GB drives means he won't ever run out of SWAP or system update image room.
For someone who consistently tries to needle folk for spending too much money for allegedly overpriced solutions (i.e. Jellyfish), Linus is remarkably off the mark in this video re: what would make a sensible case, SLOG, and power supply selection.
