About the Samsung PM1735

[balnazzar]

I've got my PM1735. TL;DR: I don't think it's a matter of drivers or support.

Here is a quick benchmark (vs. 970 pro, Linux. The PM1735 is plugged into a pcie 3.0 x8 slot, NOT 4.0):

Kdiskmark is just a GUI for FIO.

Here is a SX8200 Pro (windows 10): Screenshot_20210113_233604z.png

Now I read a couple of threads by people complaining about its performance and/or lack of drivers, but I think one has to understand that this is an enterprise drive. Note how good it is w.r.t the 970 Pro (mlc!) when lots of processes ask for great deals of scattered random data.. It's almost 3X faster. Something similar stands for seq perf..
On the other hand, it fares bad at Q1T1.. It's NOT a desktop oriented ssd...
The SX8200 pro is quite the opposite.. Great at 4KQ1T1: typical desktop ssd.

In short, if you need an indestructible ssd (dwpd 3, guaranteed 5 yrs), and with very good high-load performance, go for it.
If you need a desktop drive with 10X less endurance, buy some 980pro.. It will be waaay faster in typical desktop scenarios.

Testing high performance SSD or NVME with 1GB... not really worthwhile data\results.
Test it with 10GB or 20GB, what's it show then ?

Also test it for 5 hours what's it show then... big difference here in consistent performance you're not testing for.

It's not so much you need high DWPD that's part of it, if you DO need it, but consistent performance is the HUGE part to enterprise.
For a short 1GB burst whichever has the cache and is configured will be fine for that, but then again most short-bursts you can't tel difference in MS here or there anyway.

I missed this reply, sorry. Here are results with 16gb, although 1gb is not exactly a short burst of data.



These results are in line with the ones using 1gb.
More threads and qds, and the PM1735 gives much better results than the MLC 970 pro.
Note also that it's installed in a gen3 x8 slot.

I agree about getting something else for desktop usage. Problem with the 980 Pro is they switched to TLC instead of MLC for the 970 pro and it's endurance is much lower. Only 600TB.

Even competitors like the WD SN850 are 1.2PB. Or Corsair MP600 Pro at 1.4PB. (Even though they also use TLC)

Ah well, i guess for regular desktop usage it shoulden't matter too much.

I guess it depends. There are workstation tasks that access the drive concurrently. I found experimentally that the break even is q4t4. Not that high. Note that the 970pro is one of the best gen3 drives as for random performance, and in q1t1 the PM1735 is just 8Mb/s behind.

Better to say 600 DW. That is, with the 2tb version you get 1200 Tb.
As a matter of fact, however, the 980 is no pro. It's just a evo-class ssd rebranded as pro, thus disgracing the pro brand name.

Even competitors like the WD SN850 are 1.2PB. Or Corsair MP600 Pro at 1.4PB. (Even though they also use TLC)

Are you sure? I was under the impression that the SN850 (which is substantially superior to the slower mp600), has the same endurance as the 980pro. Source: WD_BLACK SN850 NVMe PCIe 4.0 SSD Review

I'm not sure.. Put on it the swap file/partition and-or the hibernation file. You'll wear it pretty soon.

For a data-analysis workstation (like mine), a lot of big fatty data will be constantly be moved on and off it.. And so on.

But yes, for 'gaming' PCs a 980pro or a sn850 will be more than enough.

Been using a Intel P3700 now for 4 years on my developer workstation and its still 100%, only 150TB total reads/writes.

I mean the newer MP600 Pro, it's of the same speed. Don't confuse with the original MP 600.

And you are right, the 980 2TB is 1.2PB as well, it's listed incorrectly as 600TB which is for the 1TB model.

Great drive for its times. Still great in many ways.
But which kind of tasks are you running on it?

Indeed I confused it with the MP600 "standard".

But damn.. I checked the prices right now and got spooked...

Using the P3700 1.6TB just as a regular workstation drive, doing webdevelopment, running vms, docker, etc. Some gaming.
Was on X299 with Intel but upgraded to X570 and AMD 5950X now so going for the 980 Pro 2TB.

A data analysis / deep learning workstation has a different plethora of usual tasks. You got to continuously load and unload big datasets from huge spinning drives to the working ssd.

Was on X299 with Intel but upgraded to X570 and AMD 5950X now

Two OT questions:

- Do you feel noticeable performance differences with the X299 platform you had? I got a Xeon 8260M and was thinking about a similar transition.

- Which X570 board did you buy? Is the chipset fan bothering you?

 

[Waterkippie]

Yea the 5950X is much faster than the i9-7900X i had. No more CPU bottlenecks now, its combined with a RTX2080 Super and the GPU is the bottleneck now. (100% load in certain games instead of the CPU)

The 5950X has 16 cores vs your 24 on the Xeon 8260M , but it's clock speeds are much higher so you will def notice a performance boost.

If you rly need more cores, look at the new Threadrippers.

The Gigabyte Aorus Pro X570, chipset fan can be turned off in the BIOS on lower loads, but even when turned on you can't hear it!
Great motherboard.

Thanks, that was useful info!
