Lolight

It should be sufficient for light loads. btw, I'd advise to replace the PSU with a newer, known quality model.

It can not. The process would require an installed in the socket CPU. If you purchase the 13100 and the board comes with the outdated BIOS then you'd need to borrow a 12th gen processor just to run a BIOS update.

While idling (no activity with reading and writing anything), all of my USB 3.0 drives run significantly warmer to touch, as compared to the USB 2.0 ones. IMO, the USB 3.0 consumer flash devices are not designed with long-term durability in mind as is the case of being constantly (24/7) connected to a power source in the always-on Unraid NAS.

All depends on your system configuration and components. Intel is the default choice for power efficient systems.

None at idle, if your system is capable of and configured to achieve higher C-States.

You'd probably need to update that motherboard's BIOS for it to become compatible with the 13100. You might want to downgrade to the 12100 if you don't want to deal with that.

A good advice on placing HDDs in anti-static bags when in storage - also keeping them away from direct sunlight and wide temperature swings. If stored for a long time, then they would need to be periodically spun up for a few minutes, preferably once a year.

As @trurl has already mentioned, add enough of HDD space in bigger disks to hold your existing data. Don't add every disk to the array unless you start running out of room. Your proposed motherboard will have 6 SATA ports. If you don't need to use more than 6 disks at the moment then connect them to the mobo and save on electricity. You will always be able to add the HBA card later on.

Welcome! An enclosure cabinet for your server? Or you meant to ask about my preference for a computer case? The main reason for my preference for a regular, non hot swap case is, in general, significantly less restricted air flow as compared to a similarly sized hot-swap. The hot-swap's convenience doesn't make much of a difference to me since I don't move HDDs around all that often. Another reason is the hot-swap's use of back planes - just another potential point of failure.

The 3.3V pin problem is generally known to affect WDs. Or at least I'm not aware of it being reported on Seagates nearly as widely as it happens with WDs.

Just in case, since you haven't mentioned your source of the purchase. If buying new (or even used), try to get one from a higher volume and generally more reputable seller. When buying "New" it's real tempting to go with the lowest price listings from unknown stores. The problem with that would be that you won't know (or rather have much higher uncertainty) about their source of inventory, its storage and handling conditions. And if the prices are real low they might even be outright scammers re-selling a previously sold product as new.

@jit-010101 wasn't particularly happy with those, according to this post:

Well, it looks like you already know the answer - it's an actively deteriorating drive that should be replaced ASAP.

Como cortesia para com os outros, por favor use o Google Tradutor antes de postar na seção de língua inglesa do fórum. Google translated: "Until yesterday everything was ok but today I received a notification that one of the disks is giving an error When it starts, a test says it's completed: reading error but it doesn't even use it at all and I only hide 6tp of this disk and leave 6tb free, I don't know if it was because of the update I got to 6.12.4 or it's the HD is faulty but it seems like it is working normally or it must be an unraid analysis error I buy all the discs and I test them on Windows with soft to see the new status and errors if I hear more, everything is ok and I've already filled the files on them, as you can see, it's only at 50% for each of them. Ah, is there any way to fix this error and not lose my files?"

It's a long thread, but since efficiency is one of your concerns, I'd highly recommend to start reading through. You might find it very helpful in understanding the issues involved and will also provide ideas for your component selection.

Not a good idea if you care about power efficiency. You can always add a HBA card later on if/when running out of available SATA ports. Besides, on a brand new system, why not to start with purchasing (adding) fewer and higher capacity HDDs? Then you might never need to face the problem.

Look for static pressure front fans.

Why would he need a HBA?
