hey everyone, thinking about upgrading the pc thats in my sig. i wanna get 2- 74gig raptor 10,000rpm sata HD's and run raid, but this will be my first time and i really have no idea how to do it. i know there is raid 0 and raid 1, but have no clue what either is. if someone could sum both up for me that would be great. also, do i just connect the 2 hd's to mobo go into sata controller and tell it to run raid whatever. i just wanna kinda get some info on what i am gonna run into, dont wanna make the $400 investment if i am gonna end up running them not in raid... please help thank you

Need some feedback on RAID!

What are you going to be using the system for? That would be the deciding factor as to whether it is worth it or not.
There is an interesting thread http://www.hardforum.com/showthread.php?t=770020 about it.

RAID0 is striped.....sees both drives as one big one...good for speed, no redundancy (meaning one drive goes, all data is gone.
RAID1 is mirrored. Sees the equivalent of one drive, but data is written to both. No speed increase, but if one drive dies, data is still safe.
You install both drives, read your manual on how to set the SATA controller, and then the controller itself has a BIOS in which you go to set which type of array and which drives to include. It's very simple.

Yup,
If you are going to install Windows on your RAID array (Recommended), be sure to have the most current drivers available. Download them off of the MB website before getting started.
And if you want to boot from the array, you will have to make some changes in the MB bios to tell it to boot from the RAID.
You are going to wet yourself when you see what kind of HD performance you are about to have.

I only had one Raptor to start. I was very disappointed, and went back to my WD1200JB. Eventually I found another Raptor real cheap and tried them out again in RAID0. The difference is amazing. Not sure about the increased access times. I never heard that, and my benchmarks do not agree.

If you get a buzz off of non-alcoholic beer then RAID 0 is for you.
For everyone else, it's not worth it unless you do video editing all day long, or believe STR measurements are representative of actual usage.
RAID 1 on the other hand, can provide useful redundancy in the situation where you are very concerned about maintaining your data.

storage review said:What about performance? This, we suspect, is the primary reason why so many users doggedly pursue the RAID 0 "holy grail." This inevitably leads to dissapointment by those that notice little or no performance gain.
anandtech said:If you do insist on getting two drives, you are much better off putting them into a RAID-1 array to have a live backup of your data. The performance hit of RAID-1 is just as negligible as the performance gains of RAID-0, but the improvement in reliability is worthwhile...unless you're extremely unlucky and both of your drives die at the exact same time.
