I am building a new machine and have the following HDD's:
1x OCZ Vertex 2 OCZSSD2-2VTX50G 2.5" 50GB SSD
3x Western Digital Caviar Black 640GB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5"
My main purpose for this PC will be photo editing in Photoshop 5 and LightRoom 3. Some video editing, some gaming, and creating presentations in Pro Presenter.
I have a separate, external, HDD that I use for backups and imaging so none of the internal space needs to be saved for backup. I am thinking of putting Win 7 Ult and my other programs on the SSD, and RAID 0 the 3 WD's, to hold my data, and for increased load times for the photo and video data. I have not run a RAID array before, but from my understanding this setup will give me better performance than mirroring or running each drive as its own separate partition.
If I am misunderstood about this please correct me. If there is something you would do differently, please also let me know!!
