Wondering About PCIe Usage...

[Dash Lambda]

I'm considering getting a Samsung 950 Pro M.2 drive, but I wonder something...

 

It says it uses PCIe 3.0 x4, and I have two GPUs in my system (Z97), so I'm not sure if it would actually work.

 

I know Nvidia requires at least x8 to a GPU for it to function, and I know my CPU has 16 lanes, but I've also heard things about additional lanes being used for storage devices that are on a different controller...

 

But I just don't really know much about this. Can anyone shed some light?

the chipset provides extra lanes

how many will depend on your motherboard

 

i would suggest just getting a standard sata drive

unless youre a professional content creator, and expensive nvme ssd is a waste of money

Any reason you'd want a 950 Pro tho? 99.9% of people would not even use 5% of it's capabilities.

'Cause it's fast, and I was surprised at how inexpensive it actually was (compared to my expectations).

Would it really? Is it actually not that fast?

You would never really ever see speeds as fast as benchmarking can show you.  To even remotely get as fast transfer speeds as it is capable of, you'd need storage solutions equally as fast to copy to and from.  Secondly, you would NEVER use the multi-client IOPS monster performance it has unless you have like..20 people constantly hitting that SSD all the time.

So you're saying that, in practice, it wouldn't be faster than a SATA SSD?

 

If so, can you recommend a sensible M.2 SSD?

In practice, most SSD's will show no performance difference in daily use 850 Evo is a good choice for SATA drives.

Thing is, I really want to get an M.2 drive.

 

My case has a drive cage under the motherboard and two hot-swap bays in the front. The drive cage, however, requires sleds to mount drives, and mine are long gone.

So right now I have an old SSD (low capacity, probably gonna die soon) and a 1TB HDD in the front bays. I want my boot drive to actually be a strictly internal drive.

 

So, that's my justification...

Ah well, if you just want to strictly get M.2 drives, you can still get the 850 Evo SATA M.2 drive M.2 is only a connector type, it's not a transfer protocol like SATA or PCIE.

Mm...

Well, it is nearly half the price, so I think that would actually be the best bet.

 

Thanks~
