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

As of 1:10pm on 2/24/2016, I am seeing 1585-1693MB/s reads and 1025-1044MB/s writes with a 1TB PM951 on a 5510 running Blackmagic speedtest.

The new version of Crystal Disk Mark allows much larger data sets, so I am comfortable using it again. Here are the CDM results -

Guys, it is not any rocket science. Samsung offers many OEM drives exactly as many consumer drives. Dell uses two of them for Dell Precision 5510, 7510 and 7710.

Samsung SM951 is offered as SSD PCIe High Performance at Dell website. This is very fast drive, an OEM version of Samsung 950 PRO. It offers read speed up to 2150 MBps and write up to 1550 MBps.
Ordinary SSD PCIe on Dell website is cheaper and slower Samsung PM951. It is PCIe-NVMe drive, but much slower and offers read speed up to 1050 MBps and write up to 560 MBps.

Unfortunately, Samsung SM951 is available from 128 to 512 GB, so if you would like 1 TB, you need to take Samsung PM951.

 

Thanks. When I began this thread I was very unsure what the high performance pcie was and what made it different. That has been cleared up kindof. Then I was unsure about the real performance of the PM951. I knew what samsung spec sheets said and what some other benchmarks said about the drive (mostly from MS Surface Pro owners). But there are precision owners posting better performance (some far better) than what samsung specsheet says for the PM951.

I originally planned for two 1TB PCIe NVMe in the system I'm going to be ordering. That is significant coin ($2200 USD just for storage) and I needed to know for sure the performance of that PM951 TB drive. I am satisfied with what I've learned so far that I'm ready to order.

Tomorrow I plan to order a 7710 with one SM951 512GB and a PM951 1TB. m5000m. 64GB. uhd. I'm so excited!

thanks.

 

...or buy in a shop a part the 950 pro. I did it. Found the 512gb at 298 eur. And I will test it in the 7710 within 10 days (more or less). Faster, more warranty but especially V-Nand. This means (for the 512gb size) 400 TBW...almost three times than the (optimum) SM951.

 

BIOS is in RAID, but the drives are separate. Given the numbers I'm seeing in the benchmarks being posted, I may put the 2x 1TB PM951's in to RAID0 once I figure out the logistics of backup/restore (I dont' feel like rebuilding the system).

OS is as installed by Dell (Windows 7 Pro) then the Microsoft Windows 10 Pro upgrade applied over top. I did not wipe the machine first -- would have to take the Dell Windows 10 media on DVD and put it on a USB stick on some other machine so that I can use it on this machine that doesn't have a DVD player.

All drivers are generally Microsoft and Dell and Intel based on their update tools. The only non-standard driver I've installed is the generic NVIDIA driver for the video card.

My machine BSOD's once daily at pretty much the same time, haven't tracked down what wakes up at that time yet. Otherwise, I have no complaints, other than it subjectively doesn't feel that much faster than my previous M6600, but the 4K screen is worth the upgrade.

 

Does the blue screen show any clues like a network file or display dll etc? I've not witnessed a win10 BSOD, are they at all informative or generic?

 

generic. you can get the details after the fact just like in previous versions of Windows.

I'm getting BAD_POOL_HEADER once daily, with no real useful information. from my read of the call chain, it's not in a driver, it appears to be in Windows itself

 

Are you booting UEFI or Legacy Boot? If Legacy, I wonder it that could cause the BSOD. Also, you should be able to download the MS Win 10 USB Install from MS and install from that. I did that recently with an M6800 that came with Win 7. I pulled out the drive, put in a new SSD and installed Win 10 with the MS tool. Bonus is it came with the latest Win 10. The M6800 came with win 7 and 10 license (ordered that way).

 

My absolute favorite imaging and cloning tool is Clonezilla. I've been using it for about 5 yrs now to perform bare-metal backups on my windows and linux servers. I need to download the latest version which now supports NVMe as I've been using the same 3yr old USB live boot clonezilla thumb drive. I've not tried with NVMe yet of course, but seems from the thread below it should work flawlessly.

https://sourceforge.net/p/clonezilla/discussion/Clonezilla_live/thread/f760e713/

*edit: after doing some quick research at the clonezilla website, I'm not so sure that it actually supports restoring an image to a RAID 0 array. If clonezilla sees the array as one single drive when restoring the image to the array (such as /dev/sda) then it would probably work. But if it sees that array as individual drives (/dev/sda /dev/sdb) then clonezilla probably would not work cloning from a single source drive to the array. I think it comes down to if it is software or hardware RAID if it will work or not. I'd need to experiment before trusting it completely with a critical restore.

 

Just a tought.
Only for "every days" backup point of view: very simple, customizable and "sycronized" backup I found a very interesting software called "Cobian 11". It is discontinued since a couple of year but the author sold the license and probably the new owner will begin again the development.
Anyway, also as it is now, I believe is very suitable and essential.
I suggest just to have a look at it. It's worth it, IMHO.
