I've just physically installed a new 1TB NVMe drive into my system. My current OS is installed on a 500GB SSD but I was going to do a fresh install of Windows 10 onto the NVMe drive. Most of my games are installed onto a 6TB HDD, which is also used for storage, a few games are installed onto a 120GB SSD (but it's about 6 years old by now).

Now I was thinking I could partition the NVMe into OS/Programs and Games. That way I can have the games that would benefit most from the faster NVMe speed on the same drive as the OS but I could reinstall in the future if I ever needed to.

What would be a good size to make the OS partition for Windows 10, some programs and a bit of free space for Windows to do it's thing?
 
I recently installed a Samsung nvme 1tb evo and did the same thing.

My c drive partition is 125gb and then the rest of it as a games\storage partition.

currently got 88gb free on the os partition but then I never install much on to my pc anyway as it’s just used for gaming.

getting this allowed me to remove the 2 x Samsung 850s from the system as I was running low in space.

min of 60GB it sounds a lot but
  • window can be around 32GB
  • pagefile will be 4GB-8GB depending on your RAM
  • Hibernation file will be around 4GB
  • Programs say around 10GB (if you dint install adobe/office)
  • Windows update download cache 6GB+
  • Total 60GB. thats today without any more future updates. id go for 100GB for Windows to be safe for future use, you can always shrink NTFS later if required

    im currently using 40GB on my windows OS fresh 4 weeks ago
  • thats with all updates
  • no large Pagefile (100MB)
  • Hibernation is OFF
  • No large programs are installed just Steam/Uplay/Epic clients & FF only.

thats not forgetting Browser Tempororay files - if you dont clear often your looking at 2-20GB there depending on your cleanup

does that help?
 
120gb would be ok for most people but i find it's a pain. The combination of frequent windows updates (insider builds) leaving windows.old folders laying around and have some chunky programs installed - office, visual studio, sql server etc - means i'm always trying to make space.

For a nice mostly hassle free drive i'd recommend 250gb. YMMV of course, but it's better to have more space than not enough and if you start partitioning drives and realise later than you dont have enough space on your OS partition, you might well have problems trying to sort that out...

you can expand & shrink NTFS very easily.

But agree 100-120GB is fine. as long as you put Large programs on other Partitions. but then i also turn of system restore too.
You could always give Windows 100GB with a 40GB App partition.
 
Thanks for the recommendations. Currently still going through backing up stuff I need and sorting out things I can keep and things I can ditch. I guess being able to increase the partition size later if absolutely required might help. I think I will probably set it at 120GB or 140GB for now and see how I get on with that.

I used to use CCleaner as part of my system maintenance but is that still the go to these days or are there better programs?
