Optane Memory as Page File

[Nick980]

Ok, might be a dump question but I'm currently running two 1tb NVME drives in a raid 0 and wondering if adding a optane memory 16gb module to act solely as a drive for the page file would be of any benefit? Only issue is it would have to run at pcie 2.0 but looking at the speeds of the drive I'm not sure there would be a issue

No. Gen1 optane is pretty slow by today's standards. Your NVMe drives will be on par if not faster than the Optane module

If you have one already, you can try it and see if it feels any different. I wouldn't buy one to try it.

 

Those modules don't really have a great sustained transfer rate but aren't bad for random access, so there is a tradeoff there depending on how the data is accessed. Assuming you have sufficient ram, the pagefile shouldn't be too heavily used anyway so any differences are minimal.

Using dedicated drive for pagefile did make "some" sense back in day of HDD's which were so slow, anything helped. I don't think it would make any difference with pagefile on RAID0 array of 2x NVMe SSD's. Also in the past, RAM was a very luxury item and people often had way less than it would be comfortable to have. These days, RAM is so cheap you can always have more than enough of it without having severe expenses unless you look at the stupid fast modules. But if you look at something somewhat reasonable and still fast, you can get 32GB of 3600MHz RAM for as low as 120€. 4000MHz is over 300€. We're talking 32GB of RAM! A lot of people even today run 8GB, gamers 16GB. 32GB is not even quite a standard for all yet it's just around 120€ for not even that slow modules.

 

So, yeah, instead of worrying about pagefile, just make sure you have bunch of RAM and it just won't matter. 32GB is a very nice worry free capacity for today and even relatively distant future...
