SM951 NVMe Transfer Speeds are incredible!

[Master Disaster]

So I got a Samsung SM951 overnighted to me yesterday which arrived a few hours ago.

 

After a clean install of Windows 10 and a few passes of Atto & Crystal Disk I was more than impressed, my old RAID0 SSD setup (SATA) gets around 850MB/s Seq Read and 700MB/s Seq Write, pretty impressive.

 

The NVMe SSD gets a monsterous 2300MBs Seq Read and 1600MB/s Seq Write.

 

Now the best part is when I copied GTA V & TW3 over from my old SSDs to my new SSD I was getting a sustained 800MB/s transfer speed!! That means it was totally saturating the old SATA Bus all the time, yeah when it did the smaller files (aka 4k writes) speed did drop down to the 300MB range but still.

 

That is insane!!!

Yep...

Ahh, SSDs...

I'm wondering if the 950 pro will be worth the extra? Personally, I don't give 2 sh1ts about black PCB but if they offer a significant speed improvement over what I've already got (256GB AHCI SM951) I'll probably buy one...

I wonder how long it will take to die due to overheating...

Well my case is a decent case (Fractal Design XL R2.0) with really good cooling (if you've seen Lukes Fan Showdown video today on Vessel my setup matches his ideal setup (except I have 2 cpu fans on my 280mm rad blowing straight out of the top of my case not 1 fan blowing inside it like Lukes was) and the ambient temp in my case never goes above 25c (or at east I've never seen it go above that number anyway) so I'm really not worried about it at ll.

From what I've seen they've sacraficed seq read and write speeds a little in order ti improve 4k read and writes a little which is a decent trade off however they're already talking about how the 950 termal throttles cause the controller gets so hot.

For my money its better to have a bare naked component in a well cooled case than one shrouded in plastic and placed away from any main cooling source (like a hdd cage for example).

They need to make little water cooling units for these things, with tiny tubes.

The case and ambient temp doesn't matter

The issue is that the SSD ITSELF heats up a ton

M.2 SSDs in general already run hot and the samsung 950 M.2 SSDs are even worse

if you can find some way of measuring the temperature of the ssd you will see how dangerously hot it gets, over 50-60C which is really bad for nand

Of course it matters, if the ambient temp of the case is so much lower than the temp of the SSD then basic physics says that thermal exchange will happen from the hot object to the colder object cooling the hottor object down.

 

Plus one of my case fans is ideally positioned so that its blowing directly over the entire length of the top of the SSD, I couldn't have positioned the M.2 slot any better myself to get direct cooling from a 140mm case fan onto the SSD.

What temperature do you think this will get to if you put games on the 950 Pro and play it from the SSD or installing new games onto it.

What I'm saying is that its the SSD that heats up, not that the ambient case temp heats up the SSD

you can have 15 or 20 degree ambient temp and your SSD will still run hot because its M.2

Plus it has no heatsink, which just makes it get even hotter

 

Theres a reason the intel 750 nvme SSDs have a massive aluminum heatspreader

 

you can get a temperature monitor or some program that read the temperature of your SSD

many reviewers have shown how hot it gets, and thats definitely not healthy or its lifespan

[SkilledRebuilds]

Love that speed.

 

Like others, I'd like to see heat sensor gun readings when its under load.

I've heard someone ssuggest to buy a tiny heatsink and stick it to the SSD in order to help with temps.

 

The problem right now is i cant find anything which will recognise the SSD in a way as to read data from it. Crystal Disk Mark will bench the drive no problem but Crystal Info and Speccy both dont show it at all. AIDA64 does show it but doesn't show any SMART status or Temp data.

oh thats weird, they must have compatibility problems with nvme then

or maybe nvme doesnt have smart? idk

you can use a laser thermometer to read the temp from the chip, those are pretty cheap on amazon

or some pc fan controllers have temp sensors on a cable that you could tape to the SSD

 

you should definitely put a heatsink on it, use some arctic silver thermal adhesive or double sided thermal tape

the arctic silver isnt removable though, thermal tape would be safer

So AIDA64 prompted me to update to a beta version today, I did and now it has a temp sensor reading for the Samsung SM951, still no SMART status yet so its either the drive doesn't support SMART or they're taking their sweet time adding support for it.

 

As it turns out my drive is running at an identical temperature to my WD Black, around 32c. The screenshot below was taken after a 10GB file transfer had just finished from my SATA SSDS to the NVMe SSD.

 

 

I don't see that as am issue? Yeah its running at the same temp as a mechanical drive which I do agree is kinda insane but that temp isn't exactly melting point.

yeah one file isnt going to do much to heat it up

extended writes will
