What should I do now that I have my SSD? Superfetch/Prefetch, disk cache, pagefile, virtual memory, etc. location

Hey guys,

I just got one of the Samsung 840 120GB SSD on sale through Newegg this weekend, and I had a couple of questions. I'm running a SSD/HDD combo (120GB SSD/1TB Seagate) as is common among builds these days. I decided to do a fresh Windows 8 install versus cloning my old drive because it would give me an opportunity to configure my system to better utilize my SSD.

What I've Done So Far: (BTW I'm open to any critique/constructive criticism on anything that I've already done...after all, that IS why I'm reaching out to you guys! :) )

I guess where my questions lie is:

I'm concerned that by splitting my installations among multiple hard drives I'll run into problems in the future.

    -Turn Off Windows Write-Cache Buffer Flushing
    -Turn Off Multi-Boot Selection

    and maybe some more stuff: source (the link also explains how to do those 3 things I just mentioned)
  2. Well now my system hangs when restarting :-/ I followed the guide exactly
  3. I don't know what to say, as I've followed the guide as well and it worked for me. :S
  4. Idk either, it hangs for like 15 seconds when shutting down :-/ Ill change the msconfig boot back to standard..maybe that will fix it
  5. I'm curious, did you find out what's making shut downs hang?

    ACHI is a feature of the motherboard's system BIOS. The rest of the tweaks you mentioned are adjustments to Microsoft Windows. Some of them are old ones that go back to the early days when a 32GB ssd cost more than $100.00 and users only installed the operating system which tended to expand in size as time passed. Think of it as making Windows more efficient because of limited space on the ssd.

    OOPS! I have to take care of something. I'll have more info for you later today.

    Sadly I didn't, but the problem has been replaced with another... Now when I leave my computer for an hour or so and come back to it the screen is black with no sign of my cursor or anything, just black. ...I have a G15 keyboard with an LCD on the top, so I can see the CPU and RAM activity moving...so i know that the system is still "alive and well", I just cant see anything!! The only way I've found is to force a reboot with the reset button/ long pressing the power button (which i REALLY don't like to do :-/ )
