Be very careful with RAID, particularly RAID 0, which I consider highly dangerous. RAID 0 (striping) doubles the risk of losing all your data, while offering only marginal speed improvements.
- upgrading a 10,000 RPM boot drive = huge, noticeable performance improvement
- upgrading from one drive to two drives in RAID 0 = marginal performance improvement, doubles your risk of irrecoverably losing all your data.
It is impossible to recover data from a stripeset when one of the striped drives fails. That is why I heartily recommend option #1 and I strongly discourage people from choosing #2.
PLEASE READ THIS ENTRY before choosing RAID 0 (aka striping) or responding to this comment.
If you respond to this comment in a way that indicates to me that you haven’t read the above entry, I’ll delete your comment without a second thought.
If you’re going to use or recommend RAID 0, you better have a highly specific usage scenario in mind. It isn’t appreciably faster for 99% of user desktop scenarios. Doubling your risk of drive failure for 1% perf improvement is a very bad deal and it is downright irresponsible to recommend this approach without severe warnings.
