mirroring is a process where the disk2 copies all data from disk1 for data retrieval. so effectively you are left with half the space of your hard disk for utilization.
 
The performance depends on your disks and controllers . Yes u can always use raid on your desktops pcs .The performance difference is so much that will love it . People spend insane amounts on PSUs ,heatsinks and stuf....to get few extra MHz. If you buy a good controller it will be goood investment . Recently i tried Intel Matrix Manager (FakeRAID) and Sil5723 . I got better than SSD results

You have two basic types of

1) Mirroring - Raid 1 (Max performance, but only 160gb)
2) Striping - Raid 0 (U will get 320GB, but lower performance and u need both disks)
Mirroring ovbiously mirrors, thus you get fail-over features and higher performance

Wrong info.

Mirroring lowers performance due to the overhead of writing and syncing to the second drive simultaneously. Also storage is halved as the 1st drive is mirrored on the second. Loss of one drive still leaves you with the exact mirrored data on the other drive. Reads are a little faster compared to a single drive.

Striping gives the maximum performance among all RAID configs at the cost of reliability. Data is striped as in halved between two drives. You gain storage of both drives but the loss of one drive leaves you with gibberish. Reads/ writes both improve.

For someone not looking to pay a premium for reliability or performance, RAID is redundant :cool2:

@nitant, thou shall not take the lord's name in vain :bleh:! Always google 1st :).

Btw, I use RAID0 for the OS and RAID1 for storage. RAID0 is just for kicks :P while RAID1 is due to a loss of some very important data to a HDD failure.

So RAID = Reliability and RAID 1 = Performance

You mean you've got 4 HDD ? 2 for OS only or installed programs as well(Games etc) and another 2 HDD for Storage of media etc..

Read it again. RAID1(mirroring)=Reliability and RAID0(striping)=Performance

RAID1 does not equate performance.

Yup. The raptors you see in my siggy are in RAID0 and the Seagate 7200.11s are in RAID1.
 
:Oh my God:

To admin/mods: This thread has to be the top misinformation threads on TE, can we lock it and have a sticky with the right information pasted somewhere instead of trigger-happy noobs quoting from sites, and messing up while they're at that?

Guys, RAID 0 = Striping = Performance. How many times does this have to be said? Get it into your heads already! RAID 1 = Mirroring = Failsafe! It should not take 26 posts to get it right, please.
 
raid 0 alone provides no redundancy but its still called a raid...its like fetching water from two pumps when both pumps are dependent on each other
