Good SSD NVMe are fast enough
 
There are test, look it up. 
Doing optane cache for NVMe SSD is not good for performance, and uneven, as the driver is to small. 
 
And I say that as somebody with optane 905p 960GB OS drive. 

Don't do it... 
 

No

No

No

just ignore it, 500mb isn't worth fighting partitioning about.

That's a slow PCIe 3.0 Dramless SSD
Mushkin Helix-L : Silicon Motion SM2263XT (2-core R5, 4-channels 800MTps, 28nm TSMC, DRAMless) + 64l TLC micron NAND (NW918 FG)

like why? 
 
why PCIe 4.0 in 500GB SSD? what's the reason? 
If dramless is ok, go for SN580, and that's the lowest I would go.  If you want faster, go for something on Phison E18

It would be easier you name the country (we assume USA), and budget...

They're both 0. Remember, the first 4 digits are the error count, and the final 8 digits are the total number of seek/read operations.

That cabble is done 

the most likely scenario, is communication error to the new SSD, or some other problems with it. 
First change the SATA cable, and port, just to be sure (usually the culprit for the communication errors)
Run Crystaldiskinfo and share here a screenshot of all smart data of the 870 evo (as well as the main one, just to be shure).

Also do post full spec of the PC.

As this topic have spin out of control I would like to clarify some points, as it's needed... 

Starting from interface of HDD.  SAS vs SATA.
SAS is faster, as interface, but it's not doing anything as the physical HDD is still the bottleneck. 
There are 10000 and 15000 rpm drives with both SAS and SATA connector (usually SAS, but there are some SATA ones), ther's no benefit here for SAS. 
SAS is redundant, as a connector, but that's that, nothing that matters for the HDD lifespan.
as for the longevity of the HDD,  it doesn't matter, it's just a connector.

Next for the empty space vs faster drives. 

First HDD depends on the technology:
if it's CRM, then yes, the starting sectors are faster, and it's almost linear drop in speed, as we go from first sectori to the last.
But you have to partition the HDD, not just leave empty speace, to use that. In old days, soft Short-Stroke hdd, by using partitions, was quite well known. 
if it's SMR, you want to leave some empty speace, as this type of HDD, can't just rewrite the data (it's like SSD, it uses some sort of FTL, and use TRIM to clean sectors), it's need to free up some empty speace for furtre writes. 
You should give it proportional free space to the amount of your writes at very least. And do give it some idle time, to do it's magic in the background. 
You can't defragment this type of HDD (as it's behind sort of FTL, like SSD), and hdd is not file system awear, so with time, best thing is to just format it (secure erase), and start fresh.

second it's SSD, still depends on the technology:
If it's 3D Xpoint, then it doesn't matter
If it's NAND TLC and QLC, then you want to free up, up to 3 times more for TLC, and 4 times more for QLC of free space, to the writes for pSLC buffer to work (writes faster)
Sometimes, manufacturers leave some Over provisioning space, to mitigate that, and for wear leveling. 
it's also not recommended to fill up TLC, and QLC SSD above 90-95%, as SSD writes data in paralel, to empty NAND strings, if there is no enough of empty strings to write to paraler, the write speed drops. 
This also have downsides, with wear leveling algorithm, as on filled SSD, the controller can't do the magic, and realocate the data, to even out the wear on the NAND 

Now for the wear leveling, and defrgmenttions. 
HDD CRM, leave some speace for derfagmrntation, so it can do the magic, nothing much. The impact on life expectancy is meaningless. 
HDD SMR, leave more space, as HDD needs to TRIM itself, and prepare clean space for the writes, derfagmrntation don't help, do not defragment. 
SSD NAND, leave at least 90% or more, for the wear leveling algorithm to work, it do have impact on live expectancy.


 

Neither of these are true.
 
SAS and SATA drives have the same life expectancy, if comparing the same models.
 
Filling a HDD is fine. Filling an SSD is not.

..huh?
If a drive is getting bad sectors that means it's failing. 
 
 
If you want to get 10,000RPM or 15,000RPM drives, sure, get SAS. But a lot of the SAS drives are literally the same SATA drives just with a different controller until you get into the range of drives that are like $400+ each. Really not worth it.

Yes, as Kilrah says, you can use some tools to do it.
 
Bear in mind this will be moving the data on the drive. Have a backup.

You can only expand a partition into empty space on the right.

This goes back to partitions being physical places on a spinning disk.

yes, it should have worked, so no idea. 
There's nothing in the manual, try updating uefi, or if there is any setting for the PCI_E3 slot (sometimes, there's a PCIe splitter, and you can set the PCI_E3 to x4, or x2, or x1)

 
this is most reasonable idea.
Do also consider running second adapter, from bottom M.2 to PCIe x4 slot (it the bottom M.2 slot is empty)

To be honest, these two SSD cost so much, you could consider changing platform to PRIME X670-P, or wait for the x690E, to get full bandwidth. 
 

The USB to NVMe bridge is larger bottleneck, then lack of HBM, but it’s already over USB so latency penalty, and worst 4K, probably won't matter as much, but it still add up to it.
But well, if there’s a good dram SSD in the same price, go for it, if not, then NM790 is ok mid range PCIe 4.0 SSD. It’s just that it’s maxio and YMTC. 

We dont have any tech that can do that really yet.
 
There's some expirimentation with glass/crystal storage, dna storage, obsidian storage,... but that all is proof of concept and not used.
 
What you want to do is currently not feasable part from engraving text in a rock tablet 😛

Then sell it, to minimize the loss, if you can't use SAS PCIe controller in your PC.
Buying entire PC with SAS controller ( or SAS capable nas ) is just not financially feasible.
 
There’s a reason you can have a good deal for buying SAS HDD, this is exactly that reason.

The Phison E18 based SSD are actually one of the coolest. 
 
as for enclosure, do note, that HBM do not work over USB. 

Nope. Sorry. It works the other way around, i.e. you can plug a SATA drive into a SAS port.
 
Your cheapest option here is probably to get a PCIe SAS card for your computer.

That drive is single sided.
