Does SSD speed make a difference with OS?

[AmirMC]

I've currently got my windows OS running on a Samsung EVO 256GB SSD. I've recently purchased a new Samsung SM951 512GB m.2 SSD for my games and I was wondering, considering that the m.2 has a significantly higher read and write speed:

1. Would I see performance increase with my operating system if I put it on the new SSD.

2. If I DIDN'T put my OS on the new SSD, is there any chance that the read and write speed of the games that I DO put on it, could somehow be bottlenecked? Eg. BF4 on m.2 - origin app on Evo SSD - cpu.

What I'm asking is, is there any thing bad (speed wise) that could come from not moving my OS to the new SSD? What is the max speed my OS would even use? Is my current SSD Sufficient? Or should I transfer it to the new one.

Thanks.

You probably boot even faster

1. You might see faster boot speeds. But in general no.

2.No.

Not necessarily, realistically the SATA interfaces are enumerated before PCI-E devices (assuming that the OP was talking about a a PCI-E not a SATA slotted M.2 based on throughput difference comments) 

 

With bandwidth and latency not being a real factor even between the two devices (most likely processor limitations on boot speed at that point) the extra delay could be significant comparatively.

 

To answer the original question unlikely to significantly help putting the content you access most frequently (like the games) is your best bang for your buck if you wanted to try putting your swap partition on the new M.2 device may be worth trying and that can be done without actually moving the whole OS

The SSD communicates over the PCI-E lanes. It's a X4 speed gen 3.0 SSD. When i connect it to the M.2 slot on my motherboard (Rampage V extreme) It automatically disables the bottom X8 PCI-E slot.

Using Samsung Magician's "Rapid" Technology, my current SSD is reading and Writing at around 14,000 MB/ps. Though it is rated at around 500 MB/ps.

My NEW SSD is rated at around 1500 MB/ps. I'm not sure how this will go with the "Rapid" technology, but i'm assuming that i will still see speed improvements.

Boot times don't really bother me. But for new games such as GTA V where i'm needing to render a 50GB map, i was hoping that the new SSD would have no communication problems, or be affected by the 'slower' speeds of the SSD that my operating system is currently running on.

My GPU is an Asus 980 with 4GB of ram, so i can't imagine actual rendering will be an issue. I just wanted to organise the new SSD in a way that maximised read and write functions across my system...

That being said, do you think that my system would perform tasks faster IF the OS were on the SSD with 1500 read and write? Or, is my current SSD more than fast enough for my CPU to communicate with?

Meaning, if my current SSD and my CPU (i7 5820k O/C to 4.5GHz) were an imagined as an independent system, which would be the bottle neck? Is it the read speed of the EVO SSD, or is it the current level of processing power of the CPU?

Hey AmirMC,

 

It would make a difference if the read/write speeds are great and they are not bottlenecked by the SATA port. SATA 3 (6Gb/s) has a limitation of 750MB/s. Since this is a PCIe SSD you would have greater speeds than SATA storage drives and your boot time should be less as well as all loading times on applications and games on that SSD and transfer speeds should be even higher. SATA SSDs are already fast enough to have a very responsive build, but you would have to use heavier applications to actually see the additional speed increase from the PCIe SSD.I don't think anything would bottleneck the PCIe SSD (in your system).

 

Your current SSD should be sufficient enough. If you happen to transfer the OS, I would strongly suggest doing a fresh install rather than cloning it as the PCIe SSD could be recognized as a SATA one and cause some problems.

Thank you, very much.

 

I was seeking a little clarification on something though, because i didn't quite understand.

 

Were you saying that the read/write speeds of the M.2 WILL be bottlenecked by the sata 6GBp/s limitation, or it won't be? The read/write speeds of the m.2 are around 1500-2200GBp/s, which is still significantly less than the limitations of the sata port. So I'm just wondering if the files loaded from the SSD are going to be bottlenecked as they "pass" through the EVO SSD OS, before they move on to other parts of the system for rendering/processing?

I think i'll just leave the OS on my current SSD and use the PCIe for games and such.

The read/write speeds of the current SSD are fast enough due to Samsung's RAPID technology, anyway. And i don't believe that RAPID would function on the new M.2, because it isn't made to be an auxiliary drive and so is probably lacking the support from Samsung.

The speed of this particular PCIe SSD seem to be around sequential write 1500MB/s and sequential read 2150MB/s which in Gb/s is 12000 write and 17200 read  about 2 to 3 times more than the SATA3 limit. It it was a SATA SSD, it would be bottlenecked, but it does not use the SATA port, but the PCIe and thus it should use its full potential.

You might have some issues installing it, but most Z87 and Z97 motherboards should support it (with or without additional updates) and newer X99 motherboards should support it out of the box. You should be OK using it and get even faster speeds. If you have any doubts, do call the manufacturer's support for more info or if you happen to have problems installing it. Also post some screenshots of the drive's benchmarks and real life performance.

Thanks, i got it today and installed it all fine.

I'm getting 1500 read and write speeds. Not sure if it's going to be restrained in some regard by the 'slower' OS SSD when gaming, but i guess we'll find out.

Cheers.

Great! Those are some amazing speeds. Use them wisely "With great power comes great responsibility"
