Samsung PM1733

[balnazzar]

Hi Folks.
I can get the PM1733 for a decent price, so I'd like to have your opinion about it, since I didn't manage to find one single review about it.

Why do I think it's interesting:
1. I got a ROMED8-2T, supporting gen4 drives.
2. I have 4 GPUs and don't want any M.2 drive to be roasted underneath them
3. I can use Oculink-to-u.2 connectors for them.
4. High endurance: I'll use it to host an hibernation file.

I don’t have an opinion, but i’m thinking of getting some too - what I am trying to find out though is what those 4 square connectors are, and how I can adapt them to my motherboard’s m.2 socket?

I don't know what exactly these connectors are, but the drive should have a standard U.2 connector (SATA-similar). At least it seems so judging by:

I’m out of PCIe slots unfortunately :-(
If it’s a standard u.2 interface then I should be able to find a cable for that I guess.

The first one I linked (Amazon.com: DiLinKer M.2 to U.2(SFF-8639) PCIe NVMe SSD Cable- PCIe NVMe U.2 (SFF-8639) Drive to M.2 Host Adapter-U.2 SSD Converter -with Power Cable(50CM): Industrial & Scientific) allows you to use a standard M.2 connector. What mobo do you have?

 

[human_capitalist]

Oh! Somehow I missed that, thanks!

I’m currently putting the parts together for a Ryzen 9 workstation build and thinking of using this board

Pro WS X570-ACE｜Motherboards｜ASUS Global

www.asus.com

with a 16x graphics card and 8x Mellanox 40GbE, I need to connect my SSD via an m.2 port.

Also re your original question, I just found this... one guy claims to have returned his PM1733!

Mh, the guy says the drive performs as it should in a GUI benchmark, even if it's not clear which kind of GUI benchmark he's using...
I think that stuff should be investigated a bit better.. hdparm is not the most orthodox manner to benchmark a ssd..

But you still have the third X16(X8) slot, right?

 

[human_capitalist]

The top 2 slots are driven by the cpu and only have 16x of lanes between them, so if I want the full 16x for the graphics card, the other has to remain empty.

The 3rd slot is driven by the motherboard at 8x, I’ll use that for the Mellanox.

In understand, but be aware these are gen4 slots.

In other words, if you use both of them, they'll go at 8X each, that is 16X gen3 equivalent. You won't see any performance degradation with your graphics card (if unsure, benchmark it).
Even if you have an Ampere gen4-enabled card, there will we no difference whatsoever.

As a sidenote, even if the third slot is driven by the pch at 8x, the link with the cpu will still be 4x (no Ryzen can handle more than 20 lanes in total). no need to worry for your mellanox though, since a 8x gen3 card would still work at full bandwidth in such a slot.

 

[human_capitalist]

Really!? I didn’t know that! I guess that makes things easier then!

A lot easier. The only use case in which you should worry about lanes & gpus is when you use multiple gpus (without nvlink). But that's not your case.

I was attached to that board because of 16+8, but if 8+8 is just as good, I could choose almost any board couldn’t I?

 

[balnazzar]

In the end I ordered two ssds: one pm1735 1.6tb, pcie, and one pm1733 u.2 1.92tb.. Risky... but I needed enterprise-class realiability.

I'll tell you how they perform.

 

[balnazzar]

Yes. Better if it's a gen4 enabled board.

 

[balnazzar]

Yes. Better if it's a gen4 enabled board.

note that as a matter of fact yours (I have it too) is a 16+4 or 8+8+4 board. Which means 16+16+8 gen3. So, it's still a good board over other 570s...

My ws x570 ace is still uninstalled since I'm waiting for a 5900x to be delivered.. Can you tell me if the chipset fan makes noise?

 

[balnazzar]

P.S. note that you can connect an U.2 drive using the minisas connector.. The board manual specifically advertises it for connecting u.2 nvme drives.. You just need to buy a cable on amazon.

oh I’m still window shopping! That’s something worth thinking about for me though I guess, Passive cooling might be nice.

I saw that the specs said the u.2 was gen3x4, so I thought for that drive I had better use something else

Uhm, interesting. Then one should use a pcie slot. May you link me that info in the specs? Thanks!
