Have you thought about a PCI-E SSD? Bypass the SATA controller entirely, plug that shit into your Bus
But if you are spending that much, I'd still really suggest at least getting a small SSD for your OS. It makes general computer usage so snappy and wonderful. It's right there with 120Hz monitors as my 'must have' of the last two years.
The reason I was skeptical about doing an SSD for the OS is that SSDs have vastly shorter average time to failure than magnetic disks. I don't mind losing the stuff on my secondary drive, but losing your boot partition is a massive headache. That being said, this will be my first SSD so I only say this from stuff I've read, and not from experience.
When stuff dies after two years (unlikely) then it's a quick evening of troubleshooting the part and sending it off for RMA, which is exactly what would happen with your PC as well.
I had this nightmare experience recently where a failing power supply caused me to replace my
entire system before I finally figured out what the problem was. Started out with just random blue screens every few weeks, eventually progressing to every few days. The driver being complained about was the video card driver. After it got frequent enough and diagnostic attempts failed, I decided the first course of action would be to reformat / re-install the OS.
Everything seemed to be better for a while, but then the blue screens came back. Tried everything, and after a few more weeks of this I decided to swap out the video card. Everything was better again. Fast forward a few more weeks and then my PC would occasionally hard freeze and I had to pull the power cable to restart it, or sometimes it would just reboot by itself. Now I started seeing a new problem, which is that when I booted it would sometimes fail during the post check and say that the CPU overheated. I installed some temperature monitoring software, and everything always looked fine. But after having enough of this (maybe a month or two) only thing I could think of to do was get a better cooling system.
So I got one of those ultra powerful CPU fans, turns out it was the wrong size and wouldn't fit in my case. Money wasted. Got a new fan and tried again, didn't fix the problem. So I thought maybe I didn't put enough thermal paste on. Re-applied thermal paste and tried again, and the problem kept happening. Running out of ideas, so I figured I would just replace the entire motherboard and CPU, it
must be the motherboard right? Keep in mind that between each hardware change is at least 3 weeks of usage time, so at this point my computer has been pissing me off for
months.
So I replace the motherboard and CPU, and now I get a new problem. Sometimes everything works fine, sometimes I hit power and the fan spins for about a half second and then shuts down, and sometimes hitting the power button does nothing at all. At this point I'm like "ohhhhhhh, so all along the problem has been the
case" I thought maybe the wires connecting the power button to the motherboard either were shorted, or the solder was coming off and the connection was loose.
So I bought a new case. Turns out the case I bought was a piece of shit, and now the power button on that case barely works at all, but it actually didn't even fix the problem. So finally, it dawned on me. The only thing left was the power supply.
Everything works now, except I have this shitty case. I wasted over 6 months and probably $1,000 in unnecessary parts trying to diagnose that goddamn thing. After that I told myself that I was basically done, I'm getting support next time, even if I never have to use it (certainly the most likely scenario, since my experience is not common) the peace of mind knowing I won't have to go through that again is worth the couple hundred dollars.
