My opinion will most likely be the only one that states this, but no, I wouldn't bother. Downside is it'll probably use 4 GB of your 16 GB of ram. The upside is that it'll delude you into thinking that the feature is increasing your performance by several factors. Truth is, that the samsung magician takes a very short snapshot of your drive's performance, which doesn't reflect real world scenarios, as far as the rapid mode feature is concerned. There was a performance review that I once read online that highlighted this with graphs and data, but I haven't been able to locate it since I read it. At the time, 16 GB was what I had installed and I needed every single GB for my VMware lab. Due to the fact that the performance increase is negligible, I didn't think the consumption of 4 GB was worth it.

Thanks - I've been having problems with Event Viewer reporting "This may indicate that the system is low on virtual memory, or that the memory manager has encountered an internal error." while loading the DNL and other svcs. Don't know if that is exactly what's going on but other sites and reviewers have said much the same thing.

+nirvananow Your issue sounds like your page file was manually set to the wrong figure, or Windows is mismanaging it. If you google "set windows page file" you'll see how to set the initial and maximum virtual memory size (page file) to an acceptable level. Many IT professionals set it to 1.5X the amount of physical memory. Personally I set it on my own computers to 4 GB (4096 MB in Windows 7) and it's worked well for me. Be aware that this setting will directly reserve the space in your storage. The system should prompt you to restart your computer after setting it. I hope this helps.

Looked at the Page file sys and it was set @ 200mb initial to 1024mb max... Probably way to low!
With 32gb of RAM @ 1.5x would be a whopping 48GB ~ sounds like a lot! Also this article {http://www.online-tech-tips.com/computer-tips/simple-ways-to-increase-your-computers-performace-configuring-the-paging-file/}
talked about possibly setting it on a separate drive: my C: drive is an Samsung EVO 1tb (931gb usable) and my D: drive which I use for immediate storage is a Samsung EVO 500gb. Anyway, I'm out of time this morning - work et al.
Thanks for you info - very helpful.

Yeap, that sounds like the cause of your problem. Honestly, with an entire 32 GB of RAM at your arsenal, I'd really suggest that you custom set both fields to only 4096 MB, then click OK, OK, OK, and click "Yes" when prompted for a reboot. However, the cleanest way to do it is:

set page file to "no page file" click OK, OK, OK, reboot.
set page file (initial and maximum) to 4096 MB. Click OK, OK, OK, reboot again.

The reason it's best to set it initially to zero, is because if you simply increase it, there is a good chance that it'll be fragmented. That tends not to be a big deal now that we have SSDs, instead of hard drives, but it's only an addition 3 minutes of time for this step.

The advice to place the page file on another drive is outdated. It was a useful tip in the HDD days, but now will SSDs, you won't notice the performance difference from that step. I would suggest placing it on your primary drive.

Samsung states that Rapid Mode can use up to 25% of your RAM, with a maximum of only 1GB. It won't use 4GB.
