What type of drives should I use to have the best endurance? Reliability isn't crucial, but bang/$$ is. Recommendations for very long lasting PSUs that work great 24/7 would be good too (should I be going into server PSUs?). Would Ivy Bridge do or is X79 better?
This will be running Windows 7, probably ultimate 64 bit of course, is there anything I should be worried about when building a comp with such a huge amount of disk space?
Can I just use the hard drives separately instead of RAIDing?
based on the amount of data it seems hard disk performance is far more important cpu/mobo/memory performance.
personally i'd look into some cheaper perhaps older spec server hardware for the longevity. Then throw most of the money into hard drives.
specifically if you could find a used Dell PowerEdge 2900 it would have everything you would need while being a bit slow by today's standards in cpu/memory.
The chasis supports 8 hotswap disks and a couple more internal as well as a few 5.25's fro whatever your i/o needs are.
it has dual psu's for redundancy and should be very reliable (but again not the fastest thing in the world)
The only upgrade needed would likely be 2 tb drives for the hot swaps and a gpu upgrade for any playback needs. The raid controllers should still be fine.
They currently go for 600-1000$ on the used market, compared with psu/tower that supports enough hard disks, mobo/memory/cpu, and a raid controller it would be hard to beat and Way, Way, Way more reliable than desktop hardware. Remember desktop hardware is only designed to be on 8 hours a day and typically 3 years longevity (longer for cpu's/memory on average though) but that means in 1 year under 24/7 use you will have used up the full life of most of the hardware.
