Can someone educate me on these m.2 drives, the read and write speeds look fantastic on paper, but in real world load and boot times they are barley as good (and sometimes worse) than regular SATA SSD’s.

http://techreport.com/review/29221/samsung-950-pro-512gb-ssd-reviewed/4

So what’s the deal with them? What is their purpose? Will software improve in the future to take advantage of these read speeds or are they just a piece of meme hardware

the fucking 850 evo is faster in some tests

BARLEY WORTH THE MONEY

will the speeds be utilised in the future tho

No, it's like buying a bugatti veyron, you won't utilize the speed 99% of the time as a consumer.

Now if you're doing heavy lifting like encoding and shit, maybe.

SSDs were never really a meme even though /g/ pretends they are

although, the 950 pro literally is a meme

We had reached the limits of SATA3 not even a year after it was adopted and needed a much faster standard. Rather than creating an unnecessarily expensive and powerhungry SATA4 standard, it was decided that unused PCIe lanes from the Southbridge would suffice. This formed into SATA Express, which would allow backwards compatibility with all previous SATA standards plus a dedicated PCIe connector, and the M.2 standard that was evolved from mSATA.
M.2 is the more successful venture into replacing SATA3, since it has a much smaller form factor to allow usage in laptops and tablets. SATA Express has yet to come to market and likely never will.
Both use PCIe lanes to overcome the 6Gbps limitation of SATA3, with SATA Express and M.2 initially using 2 lanes of PCIe 2, then 4 lanes, and then 4 lanes of PCIe. Using PCIe for non-volatile storage was been around in the enterprise market long before then in the form of dedicated add-in cards, so M.2 is a trickle-down and user friendly adaptation of that technology.

M.2 allows for much faster transfer speed (although there is rumors that Samsung has been hitting the speed limit of PCIe 3.0 4x already with a prototype drive) in a much more condensed package for better versatility. For professional media and content creators, M.2 is a cost and space-effective solution to replacing expensive SSD RAID set-ups at a much faster speed. A single 512GB SM951 will outpace even three 512GB 850 PROs in RAID 0 in almost all aspects at the cost of a single 850 PRO without taking up a 3.5"/2.5" drive bay. M.2+NVMe could help pave the way for mainstream adoption of 4K/30FPS media, since it's technically fast enough to handle the write speeds necessary for creating such a size-heavy file at a much more reasonable cost.
The only issue is that current NAND density restricts the amount of storage you can have in a M.2 stick, a big obstacle where a 30 minute 4K/30FPS uncompressed video file can be as large as 4TB.
