| If you go with RAID 1 for redundancy, you'll still get near-double read-times, and identical write times as just having a single drive. We spend a lot more time reading than writing to drives, generally, so that's why I feel RAID 1 is the best choice (and it always provides a backup if a drive dies). |
RAID 1 offers no speed increase in reading as both drives read the same data at the same time to ensure no corruption exists, and is slightly slower than a single drive when writing as it has to cross check the data between the drives.

| In RAID, you'll load windows darned fast. It amazes me that people dump all of this money on a new CPU, which is great, but having 2 identical hard drives in RAID provides massive performance increases when booting, loading programs, and accessing the drives in general. Some of the newer CPUs are blazing fast, and sit around yawning, waiting on the slow single hard drives, so having two of the drives in RAID helps keep that CPU chugging along at a more useful pace at times when things are being loaded and/or saved to HD. |
In a RAID 0 or 3+, speed increases are dependant on demand. In a low-stresss environment with few demands of the drive, one can in theory net a speed benefit of nearly 100% per drive added (say a computer where the only application is a DVR and you want to watch video footage in high speed). In a much more stressed environment such a public access server with hundreds of file requests a minute, the increase will be reduced to a much more modest 10-15% speed increase in reading as the drives spend more of their time moving the heads around rather than reading data. |

Planning on RAID 0, a bit worried about the drives going down. Will do some research on RAID 1. Will need to rip out the old FDD for the driver installation. Anybody have some experience with integrating the drivers on a Windows XP CD beforehand?
Going to build the system myself (more fun, more pain). Seems like you have to do some advance planning on cable arrangement with the Antec 900 if you don't want a mess. |
To be honest with you RAID 0 isn't that great I know I run it. Get raid 0+1 or Raid 10. Most games don't take full advantage of RAID speeds any way. Raid 5 is not bad either if you buy an intel based board you will get matrix storage tech anyway. |
