OPTANE p5820x 1.6 TB - Discussion

I now possess a pretty rare and expensive Optane drive known as the p5820x and this post will act as a discussion and I will give update as I investigate this drive further.

Very little is known about this drive and benchmarks are a mystery. Only 3 documents on Intel's enterprise SSD database indirectly mentions this drive's existence.

U.2 PCIE adapter card from Startech 4x4 speed
What kind of motherboard & CPU? Someone else here on the forums had said something along the lines of you want to have PCIE 4.0 based Optane in the first PCIe slot for the CPU because of PCIe 4.0 signaling issues.
 
Proart x670e

the PCIE lanes are x8 to the CPU.

Something is weird with this SSD. Runs hotter. Slower. Uses more power.

But are you using the 1st PCIe slot?

I mean, hotter and using more power is Optane in a nutshell.
 
But also very durable and fast!
Yup! Tradeoffs, but worth it IMO. Wish Intel had pushed forward with it, but without Micron, it was kind of hard for them sadly.
 
@NSGYPA Im curious about this drive, did you compare it directly to the standard p5800X? I would like to see them side by side in your system as different systems differ the disk performance by the latency.
Thanks
 
Freaking awesome, i recently purchased a brand new Intel 905p 1.5TB and i loved it, maybe next year i'll get a P5800X series, but its extremely expensive

Nice, for high densities gen 1 optane it’s really good, really cheap this days. If you are in a Intel platform you can even push it very high on R4K1Q

Where did you find one? I was thinking about getting another one but NewEgg is out of stock at any sane price now.

On reads i'm getting these results, these first gen Intel PCM S15C 128Gb 2-deck dies aren't super fast at writting, but read speeds and latency are incredible
P.S.: CPU used is a Core i7-13700K @ 5.7GHz all core (e-core disabled)

I have gen4 drives that can get close to 450 MB/s at QD1 (Write)

This SSD is not efficient though, i haven't tested it's power, only saw it's rated power states

Although this Controller is a monster

The Intel "SLM58 / SLL3D" is a 7-Channel monster

There's a guy selling 1.5 tb p905 for less than $100 on eBay.

@NSGYPA thanks but can you post the same results in Crystaldiskmark as with the p5820x you used that program. I guest the results should be in line between the two apps but just in case…
 
@GabrielLP14 Gabriel I see your read RND4K1Q1T result quite low for an Intel platform, I’m getting almost the same result on AMD and AMD is slower because somehow introduces more latency. Do you have the drive connected directly to the cpu pcie lanes?
Also the writing performance is indeed in par or below NAND but I guess in the NAND could be that the I/O is reported as completed by the controller before actually writing to memory so I guess those numbers could be “cheating”, I guess with optane it actually writes the data.
Not sure just theorizing.

Yes its the CPU lanes.
Writes will be slow on 1st gen Optane, for read its quite high actually, bear in mind that this is not the same Optane media as teh Optane P5800X, its a totally different die

Did you get yours from that vendor? Normally a stat like 129 sold with 0 positive feedback I'd pass on that as I'd consider that a higher risk purchase.

I know, I don’t find now any other bench of the 905p on a recent Intel cpu, but I think it can be pushed further. Btw if you wanna test try disabling C-states, you will get a performance uplift in RND4K1Q1T

kinda necro but this looks like them pushing it forward. or as much as it'll ever seem like. the problem isnt micron or anything, the problem is the patents underlying are tied up in lawsuits: https://seekingalpha.com/article/4544653-there-is-nothing-wrong-with-optane-and-3d-xpoint
... that's why everything's super lowkey - the demand for the tech's definitely there, otherwise there wouldnt be silent releases like those commanding an extreme premium

its already off

Got my p5800x 800 gb from Newegg for around $2,000

got my p5801x 400gb from eBay from Chinese vendor for about $400

got my p5820x from USA enterprise storage company for $3200

All drives tested directly to CPU PCIE lanes using high grade adapters.

I'll bench my 905P and add it to this post when I get into the office today.

yeah on AMD the random performance isnt as good as on intel

But god..... what i'd give to have that P5800X 3.2TB
