NEW Samsung 950 Pro M.2 NVMe (think SM951 with VNAND & Black PCB) yum!

I wonder if its because I cloned the 256gb sm951 with Samsung Data Migration Software to the 512gb 950 pro

Almost certainly yes.

Though thinking about it a bit more, you would have thought the migration software should have managed things correctly.

PS. Try Macrium Reflect, or Acronis TI. Never had a problem with either of these.

How have you got yours set up Crinkleshoes? I'm just looking at yours and seeing higher write speeds. Is it that you're running a pair of 512's instead of the pair of 256's I'm running or have you changed buffering settings in Windows? Are you running this as an Intel RAID set or getting Windows to do it in software?

Is the NVMe driver applicable if I'm running a hardware RAID using Intel RST?

Cheers,

I'm having to run Windows Raid at the moment - there appear to be some configuration peculiarities with this motherboard meaning while using an Intel 750 as boot drive, I can't access the intel raid array... very odd. Seems others have been having similar issue - also only 4 of the 10 sata ports function, another issue others are having. Hopefully it will be fixed in a bios update.

Yes they are 512s and the 512s will be faster than the 256s, especially in the writes department.

No buffering settings changed.

I can't answer your last question - try installing it and find out? It will only install if it detects the drives present in your system.
 
I am wanting to bench my SM951 to check that it's reading/writing at optimal speeds (sadly not quite as good as the latest pro version) and saw that a lot of different bench programs have been used on this page. Any links to something decent?

Hi the two main ones I use are

AS SSD Benchmark and CrystalDiskMark 5,

What speeds are you getting? Have you ticked the second box under device manager-disk drives-policies Turn off windows write cache this has to be done for the sm951 to help with speed

Totally unnecessary really...
Turned on for my drive and all metrics are exactly where they should be.

The Samsung Nvme drivers also works well with the sm951 drives (regardless of what Samsung would have you believe). While you won't see a huge increase with synthetic tests. If you run pcmark08 (much more real word test\s) you will see a significant improvement. See my comments after the legit review of these drives (GOOGLE "legit review sm951").

Enjoy.

PS. Don't get too hung up with synthetic tests. As they do burn through a fair few read\write\erase NAND cycles.
 
guys - I am about to do a machine upgrade and am considering either the 400gb Intel 750 or the 512 950 Pro to go in this board:

https://www.overclockers.co.uk/asus...cket-1151-ddr4-atx-motherboard-mb-679-as.html

Your opinion please on these two options. As I will be running 2 X R9 290's in Xfire on top. I know this board has a M2 slot under the coverings but wonder which is really going to be quicker/ better bang for my buck.

Thanks!
 
I have 1x Intel 750 400GB + 2x Samsun 950 Pro 512GB in Raid-0

I've tried both as boot drive and find the Intel to be more responsive in general use, so I've kept that one as my primary boot drive and the raid array is for fast-access storage... a small handful of the games I play the most, photos and other things.

A little over kill for the usage sure, but I wanted to play and if the 950s proved to feel quicker, then I was going to sell the 750.

The 750 just has that little bit less lag / quicker response / slightly quicker at loading web pages and other general windows tasks.
 
Also, I believe some people were having trouble with the 950's on Asus boards. Will probably be fixed at some point with a bios update but if you're buying now, that probably doesn't help.
 
Gentlemen, I thank you for your responses (Crinkleshoes and Cenedd)

I was torn between the two options and driving myself mad between the various reviews and performance guides.

I with they, as part of doing these reviews, talked about actual usage for tasks, e.g. loading pictures or windows boot, or loading BF4 etc. Not too many but some would be useful for sure.

Added the 750 to the wish list, may add the 950 later (as this board has a nice place to "hide" it)

Mucho gracias.
