Did I make a mistake buying a m.2 960 evo?

post #1 of 15
Thread Starter 
Hi OCN community!

I'm just a regular PC user who does a little programming and gaming. My concern is that I think I should've bought an 850 evo instead of a 960 pro. Is it true I won't see a real world difference? With a 960 evo would I at least see faster installation times for big games or big programming packages? Would I see faster extraction time from compressed files?

Can someone explain the multi-queue feature in NVME and give a real example of that advantage?

I think I can still cancel my order, so hopefully someone will help resolve my concerns smile.gif

1- Does your motherboard have an M.2 NVMe slot ?
2- read some review : ther is a HUGE performance difference between sata850evo and NVMe960
EDIT: Is it worth ? It's something that you have to decide by yourself, they both have a good price/performance balance

3- 960EVO is reliable/performing enough for a home/normal use
(I'm not up-to-date on the price difference between the EVO and PRO, check it wink.gif )

I did but there aren't clear examples. I've seen results that favor the 960 evo, or show no real world difference (in game loading for example). My motherboard is a GA-Z170X-GAMING 7 btw


Edit: My other concern is gaming or doing anything heavy load during the summer time. I don't use an AC to cool my room, so I rely mostly on fans. I feel like I might experience heat throttling. I also notice that people sometimes buy heat sinks for their m.2 nvme drives. Not much is known of how much of an issue this throttling can be for your average PC user. But knowing that it can throttle down to 80MB/s is raising my anxiety about the purchase.

in-game you will hardly see any differences

eg.: to load a map it must be first decompressed fromthe file in the installation folder, the bottlneck will be the cpu

sata3 -> NVMe the system will feel fast but not as crezy fast as HDD -> SSD

I have 960 pro 1tb nvme, intel 750 nvme, and 850 samsung pro 1tb and 500gb. Other than copying large files from one drive to another, there is no difference between any of them. In 24/7 use, gaming, internet, encoding videos, installing windows, starting windows, basically nothing that I have done can I detect any difference between any of them (and have used a stop watch on many things), and that is because small file, like 4k random read/write speed is most of what we do and is very similar on all of them.

When optane SSD goes mainstream (supposedly when kabyx and skylake x get released), then we will see ~7x faster 4k speeds, that hopefully will then be the first 24/7 use noticeable upgrade (like SSD was compared to hard drive), unless other bottlenecks stand in the way.

Thank you for that informative response. smile.gif

I just discovered that if your CPU only support 16 pci-e lanes, then installing an m.2 nvme will make your gfx card run at 8x speed. Can anyone confirm this?

The Z170 and Z270 PCH have enough bandwidth to support a 4x PCIe device. So you can connect the SSD to the PCH x4, and still have a graphics card connected to the CPU directly at 16x.

Most motherboard M.2 slots are wired to the PCH.

How can you verify this on any mobo? For example, I have a GA-Z170X-GAMING 7, and on their website it says Dual PCIe Gen3 x4 M.2 Connectors with up to 32Gb/s Data Transfer (PCIe NVMe & SATA SSD support). I would be losing bandwidth for my gfx card, correct?

Just look up in your MB manual which slot is wired to the CPU and which is wired through the PCH.
