In lack of a better Category I decided to post in here, I hope I got it right.
First of all, here's my rig:
CPU: i7 950 3.06ghz
GPU: Radeon HD6870
RAM: 6GB DDR3 2000mhz 9-9-9-24-2N
MoBo: Asus Sabertooth X58 (SATA3 and USB 3.0 capable)
Main HDD: X-Raptor 10.000 RPM 16MB Cache, 150 GB Sata1 (Have it for 6 years, seems a bit dodgy at times, does some cranking sound from time to time and I used to have some random reboots which I believe it was due to this)
Storage HDD: WD ElementsUSB 2.0 1TB
Monitor: Samsung P2450 (1920x1080)
I can play with 60 FPS with no problem but everytime I try and fraps at full-size(a must) I hit 5-15 fps. Fraps is set for 30. With this I concluded that my current writing speed is insufficient and that my HDD is my system bottleneck.
My WoW is on my main disk while my fraps is on my storage HDD. I've tried the other way around with no improvements.
I thought of buying something like OCZ IBIS 100GB 3.5" HDSL SSD (Read Speed: 740MB/Sec, Write Speed: 690MB/Sec, Flash: MLC, Controller: 4x SandForce SF-1222, Buffer: 0MB) but I was told that 2 HDDs in RAID0 would give me a better performance than an SSD.
Seeing that my MoBo is SATA3-ready, what would you advice me to get (SSD? HDD? 2xHDD's and RAID0 them?) and where to put my OS, Fraps and game(mainly World of Warcraft) to maximize my performance? Should I keep my 150gb disk too or just my future HDD/SSD and my storage disk?
RAID0 will certainly give you much better capacity and write speed per $ than an SSD (actually HDDs by themselves do that), but if you need a TON of write throughput (idk how much you'd actually need for FRAPS @ 1080p) two HDDs in RAID 0 can give you over 200MB/s writes for < $150. If you were going to add another HDD or RAID HDDs, you should just keep your current main drive and add these as additional storage.
It shouldn't really matter where FRAPS or the game is on these Hard drives, just where you write to. Also, iirc, setting FRAPS to a specific frame rate will actually cap the game's playback to that rate, making it unplayable most of the time (unless you set it to 60, and do something like, use virtualdub to reduce it down to a more reasonable size and framerate after recording)
