Been searching everywhere but there just is no info on the G752Y models with the larger stock SSDs. Nothing to be found but the RH71. Guess Ill have to be the guinea pig for the 256GB. DH72 is on the way, I was just curious as to whether I needed to order another SSD to get past the obvious joke AKA 128GB stock drives performance if it is also prevalent in the 256GB. Ill eventually go to 512 and would rather go with the 950 pro but wont without proper operation and fully functional software. Id just as soon just go with the SM951.
I've gone ahead and ordered the 950 pro 512GB. It's not about cost as believe it or not the SM951 AHCI and NVMe are harder to find and cost more. My worries were around TRIM and OP as well as warranty but after a good bit of research elsewhere my worries were put to rest.
I already have an 850 pro to replace the spinner.

I tossed it around for a very long time and spent a lot of time researching before committing. Bottom line is AHCI is on the way out. Its slim pickings on the sm951, particularly the AHCI version and they are actually higher priced. Once Im comfortable with the drive Ill most likely order up another for the other slot, I don't believe there will be the option to run two different formats, its going to be one or the other. There should be a 1TB version available soon.
I read a lot of reviews comparing the two and most of the reputable sources noted thermal issues with the SM951 with rates dropping from thermal throttling, this has been noted by pretty much everyone that reviews them and its absent in the 950 pro with V-Nand technology over the older Planar of the sm951. All reviewers had the same thing to say that you need to consider installing heatsinks on the modules if you intend on using them.
TRIM is a function of the OS after Win8, thats directly from Samsungs documentation as is their policy that over provisioning is not mandated. They say you only need to do so if you routinely have your drives loaded to capacity, otherwise its not an issue and none of this affects the warranty.
Now with that being said the SM951 is OEM and comes with a 3 year warranty from the source you get it from, not Samsung. Being OEM they also offer no support. The 950 pro comes with a 5 year warranty through Samsung and they offer full support.
So my incentive is the drives seem to work just fine without magician software, its not required. TRIM and trash are taken care of without it, OEMs don't include that software anyhow, its support is limited to consumer versions and noted on Samsung's site that not all functions work with all drives. Standard drivers are working fine and Im confident that as the technology evolves, so will the drivers. Add to that the 5 year warranty directly with Samsung, no fighting ram-city or ebay seller or newegg for warranty issues.

Actually you might want to do a google search for 950 pro thermal throttle and consider that samsung said
"Samsung says that proper airflow is recommended for the Samsung SSD 950 Pro to keep the drive operating under it's 70C threshold."
I would honestly question how much airflow does a g752 have over the 950 pro that uses twice the power of an AHCI sm951
http://www.legitreviews.com/samsung-ssd-950-pro-512gb-nvme-pcie-ssd-review_174096/3
"When we let everything cool back down and re-did the test without the 120mm fan we noticed that the drive started to throttle at the 62 second mark. Our performance went from being ~1560 MB/s all they way down to 753 MB/s and then rising up to 879 MB/s during the throttle period"
I truly hope the 950 gets some driver issues fixed but i wouldn't buy one until they do or until the next model releases.
Actually I did research it. Using your keywords the very first hit
"As you can see, you would have to write nearly 150GB at over 1.5GB/sec to get a 950 PRO to warm up enough to throttle, and when it does, the throttling is very minor, dropping to only 1.2GB/sec intermittently. The slightest airflow prevents this from happening at all, and even if there was zero airflow, the chances of maxing a 950 PRO out on writes for that long of a burst is extremely unlikely in even the most demanding consumer usage scenario."

According to the spec sheets the 950 pro is 1.5x more efficient in power consumption.
Like I said, I tossed this around for a very long time, longer than I did making a laptop choice and your earlier post about the ACHI being just as fast andfully supported is what drove me to dig so deep.
