What type of SSD should I get?

 

M2-Sata is not the same as M2-NVMe, they both share the same FormFactor and that is about it.

 

oops, i wasn’t clear.

 

i meant to ask how much faster are the load times are with m.2 nvme over the old (non-m.2) sata ssd which everything else being equal.

 

any timings?

 

i wouldn’t expect much change for a work load like dcs, but i am very interested to hear from anyone who has tried and measured it.

Being able to notice the difference in load times is hard. NVME can exceed 2Gb/s read and write; where as non-nvme will cap out at SATA III limits of around 550Mb/s.

 

That is only under certain conditions. "Normal" usage (random drive access) will be around 700MB/s for NVME.

i understand it’s theoretically faster, but what i am trying to understand is if there is any noticeable benefit in dcs.

 

i’m thinking there is not enough sustained i/o for it be noticeable.

 

but interested in some actual timings to know for sure.

 

has anyone done an actual test?

If you want proof regarding flight sims and exclusive M.2 (NVME) SSD performance just ask John Vehenma who develops all the ORBX scenery add-ons for Prepare 3D. He claims it does. Not huge, but small collective difference. The latter makes a small difference when coupled with good components.

 

Difference is, a sim like P3D can utilize as many cores as your CPU has when loading the scenery. I normally see almost 100% CPU utilization of my 6/12 8700K.

 

This is a loading graph of instant mission from DCS. It started to load just before the beginning of the graphs. It is with a regular SATA6 SSD. I also have nvme disk for system, but I see no point in testing DCS with it as it's clear that DCS is limited by CPU single core performance.

I would not buy a Sata SSD if I had the choice, sooner or later you will get to the point where it may matter.

 

 

 

But speaking hardware, both NVMe's would share the same PCIe lanes from the PCH chip, so it's not gonna be full burst both together anyway, it's rather a either or on Z370/390. Also the Sata drives are all connected through the PCH, so there are limits at what point such a consumer chipset won't show rewarding results. If you let the NVMe scream, the PCH is screaming too and all others have to be very silent.

 

 

I never liked those crippled chipsets but there aint much you could do in the recent past if yu wanted the best and fastest IPC CPU, those where Z170/270/370/390... all have this bottleneck with the PCH and many drives + NVMe.

Okay, so my 5.2 GHz 8700K and Maximus X Hero MB, 32Gb 3200 MHz DDR4 RAM are coming in tomorrow. I have the OS on a 120GB SATA SSD, DCS and Oculus on a 512 GB SATA SSD, and 3 HDD's between 750 and 2TB (My Steam library on the 2TB HDD), and all of these are about full. I was contemplating getting either a WD M.2 NVMe 240GB for the OS and/or a 500GB of the same type for the OS, DCS, and Oculus, re-tasking the 120 and 500 GB SSD's, or maybe just a 1TB M.2 NVME (about $340) to put that stuff on, which would yield even more room. I wouldn't say that money's no object, but if that's something that might matter in a few years, I might opt for the NVMe, but otherwise I could save some money and get a 1 or 2 TB SSD or an M.2 SATA (if doing so would allow me to have room for the drives I already have, because I'm running out of power cords). Any thoughts on this?

What about this?:

Or should I spend more on the WD Black NVMe, or less on a bigger SATA SSD?

I have my OS on the 500GB M.2 NVMe and also run 2 x 500GB EVO 850's

 

Keep 20 to 30% of the drives with free space on them. (Factor this in to your plans)

 

You must have a lot of games to need that much storage.:) I will possibly add another 1TB and use one 500's for videos. I cannot comment on the Kingtson, only every had Samsung. It would be hard to go back to a standard drives for anything;) Don't really have the room as my AIO is at the front of my system and I like the airflow throughput without stacking drives in front of it. I would need to move the AIO to the top to reinstall the drive rack.

 

You can see my system with no drive rack and AIO install HERE The 2 x SSD's are behind the motherboard.

you can have 1 x NVMe and all six Sata or 2 x NVMe and 4 Sata. Or 1 x NVMe M2 + 1 x Sata M2 + 5 x 2.5" Sata SSD.

 

Consult your mainboard manual for the limitations. You cannot have 6 x Sata + 2 x NVMe on Z370 Intel Chipset.

 

I would get 500GB OS NVMe, 1 TB Games NVMe, and then add another FOUR Sata of your choice

I ended up sniping this on eBay for $190: https://www.amazon.com/Toshiba-XG5-KXG50ZNV1T02-Single-Sequential/dp/B07B4J17KT/ref=sr_1_1_sspa?s=electronics&ie=UTF8&qid=1536290257&sr=1-1-spons&keywords=toshiba+xg5&psc=1
