I just want to make the system perfect for what it is. I feel like the HD might be holding it back.
Yeah, sure, for 10$, 50%-75% speed increase is nice.

I say go for it. Heck, I'll give you the 10 bucks.

This is a common misconception - RAID0 for many tasks is no faster than single drives. RAID only helps sequential performance, and your OS actually does very little of that. It does nothing for small random transfer performance, and can even slow it down over a single drive. Which means that even in RAID0, your older, slower drives will perform worse in day to day usage than single, more modern drives. When you run a sequential benchmark you will likely get similar speeds (~120MB/s max), but the IOPs rating of the array will likley be much lower than on a more modern single drive, and thus the 'snappiness' and general feeling of the computer in use will be worse.

There is also the problem of drive failure - running 2 old drives in a non-redundant array is asking for trouble without a backup, because if either of them fail (and remember they are getting old, and you have no idea what stress your 'new' drive has been through if you do go the 2nd hand route) you will lose all your data. As a result you should really have a full backup - which means buying a second extra disk, and therefore means spending the same money as you would need to buy a faster drive in the first place. So it just isn't worth it.
Ok cool. Repped. I only rep when I feel like someone saved a "life" in going the wrong way especially when I'm spending money. I cant afford to raid 0 and raid 1 so this is good news. Yea, trusting a used HD might be ok, but we've all been through the clicking hard drive so..... yea. I'll just stick with this system and save money for the next.

Thanks for your help.
