Software Raid speed advantages? or Cheap PCI x1 raid controller?

I have 2x 150 hard drives but my mother board has no raid i was wondering if software raid would speed up the system at all as in using the dynamic drive feature in windows 7 vs the speed advantage for a $30.00 Raid controller i found on Newegg.com

General speeds would be greatly appreciated because i have never done software raid and i don't wanna do it and potentially lose data if its not worth the speed bonus.

  1. In terms of real world computing there is no major boost in performance with RAID 0. Some tasks such as Drive Encryption get a good boost but for the average user there is not much profit in it. RAID 1 for redundancy is a good option for many. I would recommend RAID 0 only for those who have a specific purpose for having it.
  2. Honestly, I doubt you're gonna see much of anything in real world applications, though it should boot a bit quicker. RAID 0 also statistically fails sooner than one drive on its own, and you lose the data on both disks. I also assume your 150GB drives are not new?

    If you are going to try it, I guess I'd go with the hardware raid. Carefully.
  3. There not new but hardly used at all maybe 10 hours use on them before i got them and i have not had them over a month yet i think ill just leav them as they are because it boots pretty fast as it is and load times on games are almost nothing so it does not really matter.
