The main issue I believe is how many bits are stored per cell. https://www.reneelab.com/difference-slc-mlc-tlc.html

VERY interesting... Thanks; that's very useful knowledge.

I have the kit in hand, but haven't had the time to put it into a machine to do the partitioning/configuration yet. I /hoping/ based on its rated high read/write speeds that it will be SLC or MLC. Doing some quick Googling didn't give any details beyond that the chips are by Toshiba.

We ordered a graphics card today. We have an old LCD with a D-sub plug and a TV with an HDMI plug, so we found a cheap fanless card that has both connectors.

Once the system is up we will just run it headless, but it has to have a video card to boot. (And for us to set it up!)

We notice that during high I/O the M.2 NVMe SSD in our gaming PC runs kinda hot.

Would it make sense to use an "external" SSD that has more surface area to dissipate heat? It would also be placed directly in the airflow of the case.

Here is an inexpensive U.2 NVMe SSD:

Note that there is a U.2 connector on the motherboard we have chosen. Also note that this is an "enterprise-level" SSD so maybe it will last longer?

How hot is kinda hot? I wouldn't be concerned about warm to the touch, but it shouldn't burn you...

That looks like a really nice drive. OTOH you can get a spare M.2 drive and a 4TB backup drive for $135.

Hot enough that we don't want to touch it. That seems pretty hot to us.

It is buried deep on the motherboard so it doesn't get any cooling air.

Here are two tables from the datasheet. Note that the "mixed-use" (800GB or 1600GB) drives are lower capacity but much faster and more durable.

The CPU cooler is the almost the same size as the power supply.

Here are PDFs for the CPU cooler.

Note (step #2) the crazy thermal compound instructions!

If our calculations are correct (quad-channel DDR4-2666) the memory bandwidth for this system should be just under 80GB/s.

That seems pretty fast!

Here is a very long TR review: https://www.guru3d.com/articles-page...0x-review.html
