The Samsung 950 Pro PCIe SSD Review (256GB and 512GB)
by Billy Tallis on October 22, 2015 10:55 AM ESTAnandTech Storage Bench - Heavy
Our Heavy storage benchmark is proportionately more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to the steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.
Performance of the 950 Pro is comparable to the SM951, which is to say that it's significantly better than everything else we've tested. The penalty when starting with a fill drive is a bit larger than normal, but simply being full isn't enough to tank the performance the way a sustained test can.
Average service time and latency outliers are vastly better than any SATA drive, but NVMe doesn't seem to make a huge difference.
The high performance comes with the price of high power consumption, and the total energy used over the course of this test is significantly higher than all the high-performance SATA drives we're comparing against.

If you had $1000 to spend which one would you get? this 950 pro m.2 or intel 1.2TB m.2?srieppo - Monday, December 21, 2015 - link
Get two 950 in RAID 0. I'm currently running that and it's amazing. What you should put money on depends on your needs though. For gaming SSD is not very important. But I already run 6700k with fast memory and 980TI SLI so was a logical next step.1TB of superfast SSD is the last bit. HDD for storage, power options to shut the HDD down when idle (silent) and online backup for important data is the way I like...

Typo on pp. 9, the word "duplicating" is shown twice, or was that a really late April Fool? :Dmapesdhs - Tuesday, December 15, 2015 - link
Pondering whether to get a 950 Pro 256GB for a SkyLake laptop (MSI GE72 6QF). Despite the glowing benchmark results, it looks as if there would be little gain for real world usage compared to, say, an 850 EVO M.2 which is way cheaper (132 UKP for 500GB, vs. 147 UKP for 950 Pro 256GB), uses less power and thus would afford longer battery life. Edging towards the 850 EVO despite my nerdy addiction to speed...Killerkicker2011 - Wednesday, December 30, 2015 - link
Would the 950 pro work with my Macbook Pro Late 2013?Quarysma - Saturday, January 16, 2016 - link
I bought 950 pro but i having trouble rate. My system test results as follows:836 / 806 MB/s read/write.My system: Asus Z97m plus, 2*8 Corsair 2400 Mhz. i5-4690K, Corsair h110i, 1000W PSU.
I wonder why I'm having problems ?
Thanks for all...

I have Asus Z97 deluxe with m.2 slot, but supporting only x4 PCI 2.0 (instead of x4 PCi 3.0).So on my mobo and yours too this m.2 support only 1.0Gbit or 1.000MB.;(
I think (and asking) that with PCIe adapter i and you can put that in x8 lanes of PCI 2.0 and get full spedd with that? I have only one graphics card so this is the only way, or?

Either we get PCI-e card or will switch to the DDR4 system. I moved to a DDR4 system.I'm ordered DDR4 system and waiting for the parts.

Beware! This drive (950 Pro / 512 GB) is terribly slow, if you set your disk to be "compressed" in Win7/10. I used it save my vmware space for years with other SSD drives (intel/samsung/ocz) and never had an issue.But yesterday, we got 2x nvme 950 pro and found, that speed is dropping almost immediately to ... 3 MB/s with huge latency.
I don't know, how their firmware goes around benchmarks (which are all cool for 'incompressible' data) but for real life - this drive get a HUGE hit when OS compress data.
ps. sure, I have plenty CPU for it, so it's not the case.

Be aware the new Samsung NVMe driver 1.1 drops performance by about 10% across the board. They should update the article with new perf numbers as its giving a false impression ATM.
