For some very high performance or multi-controller parts maybe, but for everything else a marginal advantage considering how easy it is to remove a measly 5-7w by simply replacing the gap between the M.2 PCB or controller and the motherboard with something other than air.

If you didn't see this already: http://www.overclock.net/t/1574490/tpu-samsung-announces-the-950-pro-consumer-m-2-pcie-ssd/90#post_24458198

That's a stack of three 1.5mm thick 6.0W/m-k thermal pads (about four dollars worth of material) under my M6e. Last picture is load temp of the hottest part of the SSD. It's ~30C lower than without the pads and the surrounding components have almost no rise over idle.

Now I just need a board with 2 PCIe 3.0 x4 M.2 slots so i can raid 0 them :drool:

You can raid between m2 and pcie to with some boards, and gigabyte has lots of 2-3 m.2 slot boards and so does msi, for z170 that is, asus went for the mix and match m2 and pcie combo raid way.

A faster controller too would lead to more performance or run much cooler at the same level of performance. Unlike SATA3 SSDs, which are bottlenecked by 6Gbps (550MB/s), the PCIe interface is about 3.9 GB/s, which is much faster. Intel recently released a PCI-E 3 x8 SSD.

The main reason for PCI-E 4.0 is for the super fast SSDs that are expected.

Personally I'd rather have more performance. A few watts of heat is fine with me IMO.

Always back up your data though!
I'd say that even though the NAND itself doesn't get hot, the one right beside the controller might be also worthy of a heatsink.

Recalling this:

I suspect though that SSDs with such a controller are going to need to maximize their surface area for optimal cooling. Future 2.5" U.2 SSDs might look something like the WD VelociRaptor series in that regard.
IMO, the Intel SSD 750 is a far better buy.

It's faster in most meaningful benchmarks and you can already get a 1.2 TB version. There is very clearly an enthusiast market for this. I want to see more PCIe SSDs in the coming years, which I think we'll see soon enough.

I am hoping that with more volume, the price of PCIe SSDs will not be much higher than top SATA SSDs.


You do know that the Intel 750 has a higher HQD than the Samsung 950 Pro which would be used for people who actually need all the IOPS, the Samsung 950 Pro has a lower LQD which is better for the operating system and games, this is why the Intel 750 is so slow at booting and while loading games. If you only want the SSD for booting and games, the Samsung 950 Pro is a lot better than the Intel 750

The ASrock Z170 Extreme has three M.2 3.0 X4 slots.
post #126 of 438
What I'm gonna do is,
Samsung 950 Pro 512GB NVMe SSD
+ Asus Hyper M.2 X4 card
+ 3x Passive Heatsink-Black

I hope I will be able to instal windows on it and use this combo in PCIe 2.0 4x, Z97 board. Max speed for 2.0 4x is 1600MB/s. This SSD has a maximum write speed of 1550MB/s-1650MB/s so PCIe 2.0 4x shouldn't really be a limiting factor unless you do look at read speeds(2150MB/s-2650MB/s). thumb.gif

What do u think guys ?

I'm doing the same thing but running at full speed, that will work fine.

SM951 overshadows this for power users.

btw, are the chips on both sides ? o>O
post #130 of 438
Can I ask, why are you using the Hyper kit for the Samsung 950 Pro, that will not work as the Samsung 950 Pro does not use the miniSAS HD cable, so it will not work
