because I always write 100% full random data on the device before using it.

Do you mean before every use or after receiving it?

When you continuously write to a consumer SSD they will slow down for a while. They are built for short burst of writes because that is what most consumers do. For continuous fast writing you need better NAND, a better controller and better cooling.

for a very long time

Long term digital archiving is not really a solved issue. Your best bet is an active approach with multiple copies that are checked regularly.

Is this your boot drive? If so it should have been replaced by an SSD like a decade ago.

This is a bit overkill although it depends a lot on what you will use your VMs for.

I would make sure you set a TDP limit for the CPU. Some board makers totally disregard Intel guide lines and allow the CPU to pull like 200W+ continuously at full load. Limiting it to ~120W will not cost you a lot of performance but might save some power.

650W is total overkill unless you add a ton more drives. Gold PSUs are not rated below 10% load. Here they can drop to 50% or less meaning a gold 650W might consume more than a Bronce 350W unit.

I am personally not a big fan of ITX builds. You can only add a single PCIe card. And you might want to add an HBA, NIC, GPU (for transcoding), NVMe SSDs, or something else down the line. With an ITX board you can only add one. And this PC is not small anyways.

Not only a ton of work but likely also much more expensive than you might think even with free boxes. A Gbit USB adapter costs lie $10, you might also need a cable, a switch, maybe (some) PSUs, a power strip, maybe some box to put everything into... And now you suddenly are spending $400-800 on this project just to get a rather lame cluster. Those cores are rater slow, 2GB of RAM is not that much, and 8GB of storage means you also need some kind of NAS.

If you like the project go for it but do not expect this to be a wise way to spend your time and money. 3-4 NUCs are likely less expensive and much more fun.

The key to keeping your data longterm is not RAID. raidisnotabackup.com Unless you run a critical server 2 drive parity with 3 total drives is total overkill.

If you are fine with a bit of downtime during recovery I would not bother with RAID at all if you only need a single drive to satisfy your storage needs. Only when you have multiple drives being able to resilver rather than restore is worth the premium. You might want to get a new drive as they do not cost that much extra and will likely live a fair bit longer so they do not cost anything extra in the long run. You might use some of those refurb drives for your backup server though.

I would not really worry about this. You can wear out an SSD but it this is an issue a normal user pretty much never encounters.

Consumer SSDs are a thing for over a decade now and I often check how much actual people use their drives as this is logged over SMART. Even rather dedicated users need about 1 decade to hit the TBW rating and this is just how much the manufacturer guarantees the drive can endure. In reality, you can expect at least 2x as much, even reports of 10x as much are nothing unheard of.

It is far, far more likely you will lose, damage, replace it with something faster or bigger long beforehand. Unless you use it eg for a high end camera to record on a daily basis.

HDD cache hardly matters these days. Latency sensitive stuff should be stored on SSDs or cached within system RAM. It is only relevant in edge cases.

If anything more cache can be a bad indicator as HDDs with a lot of it tend to be SMR drives. However, all Ironwolf (Pro) drives should be CMR.

You can get 24TB HDDs but they hardly make sense for most users. THey cost over $600 right now. A 20TB drive costs literally half as much and you can get 18TB drives for $250.

It is not even part of the spec anymore because almost nothing used it. The idea makes a bit of sense when you consider that micro HDDs were a thing for some time and newer M.2 connector is 3.3v only.

Even a soldered ("molded") connector is fine as long as it is well made. However, it can be tricky to know if it is or not. Crimped connectors seem to be of better quality on average

If it was included with your Seasonic PSU I would totally trust it.

Flash drives kinda suck. Unreliable, bad performance, easy to lose or break. Fine for moving a bit of data between devices but definitely not something I would entrust my data to longterm.

(external) SSDs in the 1TB range are so cheap that it hardly makes sense to recommend anything else. Especially for portable storage.

Just make sure it also supports optical drives. Had to learn the hard way that not all do. And USB 3.0 is not strictly necassary as optical drives rarely take advantage of it.
