Samsung unveils a trio of NVMe SSD's w/3D V-NAND

Most commonly used around these parts should be the PM953. This puppy is an update to Samsung's SM951, and it's targeted at data centers, mobile worksations, slim notebook PCs, and high-end desktops. The PM953 will be available in two form factors: as an M.2 drive, it will carry 480GB or 960GB of storage, while the 2.5" SATA Express version can pack 480 GB, 960 GB, or 1.92 TB, respectively.



Article can be found here. I'll probably grab one of the 960GB M.2's, as long as they're SATA 3 and not PCIe.

 

J.Dre, I have been waiting for a 1TB M.2 SATA drive to get released, but the SM953 won't be it, because the SM953 is specifically NVMe PCIe interface only.

Hopefully Samsung will release a 1TB Evo 850 M.2 2280 drive soon...

The only worrisome fact is that the SM953 is a longer M.2 drive, 110mm instead of the 80mm I need for the MSI GT80 SLI-263. 22110 vs 2280.

The 80mm/2280 length might not be large enough for a 1TB drive yet...

 

Yeah, it does seem like these M.2 will be exclusively PCIe, which is unfortunately not supported with my laptop. However, I imagine Samsung will launch the 860 series next year, as this is quite common for them. The 860 series should be very similar, offering close to 200k IOPS, which will be a substantial improvement over current generation 850-series hardware. Also, a substantial size increase should be well within bounds, up to 2TB's.

 

The new drives are exciting, but '<8W' is not something geared for any current notebook that I would want to use these with.

Waiting for the report of how much they throttle over 38C.

 

I would be interested in a 2242 and a 2260 size drive, no need for slow SATA/ACHI, hopefully nvme would work in new notebooks. (we have a Latitude E7450 and an HP 720G2 in the family)

And make those thermals/power consumption better Samsung... Half of the 2000MB/sec sequential is fine, but keep the drive <50°C in a tightly packed ultrabook!

 

The heat the current 2280 M.2 SATA drives put out is shockingly high. Then they pack them on top of each other, 3x RAID + 1 M.2 slot bordering the CPU area on the opposite side of the motherboard - they get up over 70c... enough to add heat to the CPU over long batch jobs.

Has anyone done any work to discover which current 2280 M.2 SATA make/series puts out the least amount of heat at idle and under load? I have tried Micron M600 and Evo 850, the 512GB/500GB models.

 

The M.2 SATA drives don't generate much heat it's the M.2 PCIe versions.

 

HTWingNut, 70c under 100% load is pretty hot, my 980m's run cooler OC'd under 100% load

The M.2 PCIe's have gone insane with heat, like up to 117c doing a large copy.

 

Those are M.2 PCIe not M.2 SATA.

 

HTWingNut, yes, and that is what I said in my post too...

The youtube video I had been using to show hot M.2 SATA drives have gone missing from youtube.

One video in particular showed 71c peak temp for similar tests. It was a Samsung M.2 SATA 850 Evo 500GB. There were 2 installed, but the video showed only 1 active at a time.

If he had RAID0'd both M.2's, they might have gotten even hotter as they were right next to each other in a non-ventilated section of the laptop

71c is too hot for parts like M.2 SATA SSD's, they shouldn't be running that hot from a long file copy.

The M.2 SATA parts show the same hot spot at the controller chip next to the plug like the M.2 PCIe x4 parts.

I don't know why those M.2 drives don't have heat sinks, or why laptop designers don't include ventilation for the M.2 drives, but they should - long term abuse of the SSD could reduce it's useful life.

As I illustrated by providing a video of 2 different M.2 PCIe x4 drives under load, the M.2 cooling design inadequacies has caused even worse high temperatures in the next generation faster interface.

The M.2 SATA 70c+ temps are bad enough to start, that should have alerted people to the problem before they pushed temps up to 117c in the next generation M.2 PCIe x4's.

 

I guess where do you see that SATA drives get to 70C? I see PCIe do, but so far nothing about SATA. I have several different M.2 SATA drives and they barely ever exceed 40C even with large file transfer. The two Samsung PCIe drives in the video however, do get hot, and the Samsung ones I have (XP941 and SM951) both throttle at 80C.

 

HTWingNut, I have given personal examples, also check the Titan forum, and described a now removed youtube video. I can't provide any more confirmation, but I assure you they will/do get that hot under load.

My GT80 has 3 overlapping M.2 slots, and as such the M.2 drives get hotter than alone. There are other laptops that put 2 or more M.2 SATA slots together, and they get hot as well.

IDK what you have your M.2 installed in, or if you have multiples in a RAID0, but when you RAID0 4x M.2's all in close proximity, they run in the mid to high 60c's and peak over 70c.

Try doing some 300GB+ copies between your M.2's and see what temps they reach.

The M.2 SATA's do get that hot, over 70c

The higher density SSD's are the worst, the 70c readings came from Micron M600 512GB's, and the Samsung Evo 850 500GB.

The stock 2x 128GB only gets up to mid 50c's under normal operation, but I spread them out, put them in sd1/sd3 instead of the default sd0/sd1 where they overlap and heat each other up.

My G750JH M.2's were 2x 128GB, but because they were in a ventilated 2.5" bay on a large adapter card, they stayed cool, in the mid 30c's.

The lack of cooling, close proximity to other heat generating devices - like the CPU, and high density all contribute to high temperatures.

Just because you haven't seen it, doesn't mean it isn't happening to a lot of installed M.2's. I have seen it with multiple installations of different M.2's, so I personally have experienced the high temperatures.

Update: found a youtube video showing a single Crucial MX200 hitting 72c:



I have already returned the 70c+ Micron M600's and Evo 850 M.2 SATA's, waiting now for a new M.2 SATA release that might run cooler, or 1TB size, so I can run 2 of them spread apart for cooler running. So I can't run a test and capture the temps, but I did it for you on the small 2x128GB - not enough room free for a huge transfer test, so I did a 50GB copy, peak temp was 64c:



Note, the 2nd 128GB drive in the RAID0 says 58c in the capture above, but that is a refresh issue with CrystalDiskInfo, the temps tracked +-1c between the 2 drives during testing, both showed 64c/63c.
