Specifically Which model m.2 ship with precision 7000 series?

I am well over 3000MB/s with a pair of SM951s in RAID0.

 

That is quite astounding. I won't be using RAID 0 but that is cool.

Thanks @ManbirPrihar. Good info.


*edit: Seems that the Samsung SM951 is the OEM "High Performance" M.2 PCIe 3.0 x4 NVMe offered through Dell
http://www.anandtech.com/show/9650/samsung-announces-950-pro-ssd-their-first-consumer-vnand-nvme-ssd

I'll likely get 1TB PCIe. 1TB PCIe NVMe is only available through Dell (or e-bay, which came from cannibalized Dell systems).

 

Wow, that will ensure that hibernate with 64gb RAM will not take foreever ;-)

 

I feel dumb now. I didn't look at that website well enough before posting. It appears that the SM951 is the higher performing optional NVMe drive. It seems to have faster specs than the pm951
SM951:

*Not sure if I would notice in real world use, but the difference is quite radical separation between the two


Thanks

 

This is not correct. The PM951 reads at 1655MB/s and writes at 1023MB/s in the 5510. I have seen some people hit 1700+.

 

2X SM951 are 3154MB/s read and 2594MB/s write. Boot time is 19 seconds.

 

I'm happy to hear that those links may not be correct. Although Samsung website also displays the PM951 with the slower speed specs. Maybe Samsung also has wrong specs showing. I wish I knew for sure.

samsung website for pm951:

*EDIT: I found your blackmagic screenshots of the PM951 speed tests in your 5510 thread Bokeh and they confirm what you were saying above. Apparently Samsung specs/speeds are lowball numbers.

To me it seems that the SM951 is their highest performing OEM NVMe m.2, followed by the PM951 series (but not as far behind as the Samsung speed/specs show). One very nice thing the Pm951 has going for it is being the only one available in 1TB capacity ( and is still very fast).

 

Hello, Those that have PM951 (OEM of any capacity), would you mind running benchmarks and post here?

I need to know how these perform in the new precision.

I'm considering purchase of a precision with two 1TB PCIe NVMe SSD (currently the only m.2 PCIe NVMe of that capacity and is available only from Dell).

Dells website is not explicit which model is shipped as the M.2 1TB PCIe in it's laptops, but it seems it is the PM951. This is same model number as those that are in the latest Microsoft Surface Pro, which have been giving SATAIII comparable speeds. Not super great. The Samsung website itself (see my post above for the links) displays rather poor speeds in the PM951 specs.

Yet I have seen one or two Benchmarks of OEM PM951 512GB installed in 5510 systems that are on par with SM951 and PM950 Pro. I need to see more proof of what the PM951 is actually capable of. Please post your benchmarks, good or bad of the PM951 OEM M.2 that is being shipped with the precision laptops.



here is a benchmark I found online of a PM951 512GB installed in a 5510. To be honest, I'm not sure how to interpret this graph. It appears to be 2GB/s.:

Here is another benchmark of the PM951 from a system that @Bokeh reviewed. It looks like a more realistic test, with very acceptable and good #s:

Full thread with that review is here: http://forum.notebookreview.com/threads/dell-precision-5510-owners-review.784464/

Please post more benchmarks of the PM951 of any capacity in a Precision (5000 or 7000 systems), good or bad. I will purchase the PM951 1TB PCIe drives from Dell if I can see some favorable benchmarks similar to what Bokeh posted. Else I might get just a single 512GB SM951 and wait for a non-OEM 1TB pm950 Pro

Thanks

 

I think Bokeh's read numbers are very high because he put the two PM951 drives in a RAID array.

On my 7710, using Crystal Disk Mark, 5x 1GiB Seq Q32T1 test , I consistently get ~815MB/s read and ~725MB/s write on either of the Samsung NVMe PM951 1TB drives. For comparison, I get ~115MB/s read and ~110MB/s write on the Seagate ST2000LM003 5400rpm 2TB drive.

 

Thank you. Your speeds with the PM951 are respectable, although I would like them to be faster of course. Would you mind me asking few more questions about your system?

- Is BIOS set for AHCI or Intel's RAID RST (Rapid Storage Tech)?
- Did you reinstall the OS or any NVMe drivers (if so, Samsung or Microsoft drivers) as some forum users have?
- How is the stability? Any crashes?

Thank you. Sorry for so many questions.

@Bokeh, if you wouldn't mind clarifying again your benchmark speeds seen with the PM951 without Raid 0. You mentioned in reply to another user in a different thread that the PM951 was initially giving slower test results than expected, saying a faulty benchmark because of NVMe. Is that why the benchmark in your 5510 review is using BlackmagicDesign instead of Crystal Disk Mark? Thank you.



Please, more benchmarks are needed using the PM951 by those that have them. Thank you all.
