Although it's possible that a single 10Gbit connection through a Mikrotik switch could be causing the slowdown, it would have to be just a problem with your individual unit, or else there would be hundreds of reports about it. As others have said, try different ports on the switch and try a...

I think I just gave up on trying to parse the rambling "I've got this super-secret project and I don't want you to have details that allow you duplicate it, but I do want you to help me design it" to see that the data was being generated then tossed after each "project" finished, so only one set...

There is no CPU made that can handle 24x NVMe drives at full speed and still keep compute at 100%. The I/O will cause the CPU to heat up too much and so it will be throttled. But, since you won't be creating the 200GB/sec of data you would need to require 12 NVMe drives to absorb it, it really...

You say you want your CPU to perform both computing tasks and handle the I/O demands of at least 8 NVMe drives. Good luck with that, because one of the two will have to suffer. On the other hand, if you drop the idea that everything has to be in one box, you could have 100% CPU utilization for...

You could try any of the iStarUSA Raidage towers. Pick anything called a "tower". All of the towers use standard 5¼" bays to hold whatever it is that model supplies (3½"/2½", tray/trayless, SATA/SAS, etc.). I'm pretty sure all of them use standard SATA data and power connectors, so if what you...

I searched for the part number in the title and it seemed to be a U.2, but I could be wrong. Somebody snapped them all up. If they really were 750GB, even the AIC would be a good deal at that price.

The eBay listing is for U.2 Intel Optane P4800X drives despite there being no picture. There are 10 available. The price is $200 but the seller has a $40 off coupon (automatically applied at checkout) that will work even if you buy multiple units. There's also a Klarna promotion for $10 off, but...

Mine is also right next to me. With a Noctua swapped in (10 minutes work), it's only audible if there is no other sound at all in the room.

Everything where you said "I don't know". A NIC could add $10 or $300 to the price of the system. Same for the HBA. What speed is the RAM? Is it ECC? What brand are the chips on the RAM? lspci is the easiest way to start. Even better would be booting Windows PE and running HWINFO to see all...

To properly identify hardware, boot one up with a live Linux distro and post the results of lspci -v.

SATA and SAS command sets are not the same, and even with similar features (like command queuing), the SATA version has limitations compared to the SAS version. It's possible that the increased write speed on an SATA SSD would help make up for the limitations, so that the array doesn't slow...

The firmware, however, is different, and that can lead to SAS being more reliable. Remember old drive firmware that led to the head unloading every minute or so? That may have been a bug, but it wasn't SAS firmware that had it.

SATA will never be cheaper used, because virtually no computers have SAS controllers, but they all have SATA controllers. This means all the home labbers will compete with people who want one 20TB drive to put in their desktop to store their games/media/whatever. And, because many of those...

For a similar device, I just plugged one of these fans into one of the USB ports and set it on top.

In this case, though, the drive is CMR, so it shouldn't be horrible. A high quality enterprise spinner gives about 130 to 250 (inside to outside tracks) MB/sec. If this drive averages even 130, most people would be fine with it.
