how do you installs raid 0 or 1 on a new pc?i was reading about raid one :put 3 disks in stipping and mirroring for double disk reads and best disk writes,and no problems with errors.sounds good to me.writes r the way a programs writes to a hard drive.reads r the way a pc computes the info it just got from the write and produces on screen,and lastly errors are not a problem because this info is on 3 hard drives at the same time with the same info right?i think i sort of understand.please help me understand and how do i make this all happen?looks good on paper[lol]thanks......peace

To be able to set up a RAID 0 or 1, your mobo has to be able to support it. Some boards do provide raid configs, but tend to be a little more money (maybe $20).

Raid was designed to allow a computer to continue to run if a hard drive fails.

Raid 0 is technically not a raid because it is not fault-tolerant. Basically, with striping, if one drive goes down everything is lost. Raid 0 sets up the 2 drives to appear as one larger drive, and data is written across both of them as one logical drive. One drive crashing would be the same as cracking a cd in two and hoping that all your data is still there. Raid 0 is built for performance....2 drives=faster read/write times.

Raid 1 is mirroring. Basically, everything that is written to one drive is written to the other. Its an "on-the-fly" copy of all your data on the drive. This is fault-tolerant. It one drive fails, the other one still has all the data intact. Read/write times may decrease due to the dual work, but it is much more failsafe.

You can set up a Raid 0+1, which is basically a mirror of a stripe. You would need four identical drives and a mobo or raid card that can handle it.

What you are describing with the 3 drives is more similar to a Raid 5, which can start to get rather expensive. If you backup your data regularly, I would do a raid 0 for performance. If it is a mission critical machine, I would do raid 1, or raid 5.

Hope that helps.

yea double,thats what artical i was reading about said: raid 5.it is very exspensive.they were talking about four sets of 2 thats 8 hard drives.[lol]that would be a server right? thats real failsafe huh?.i was trying to make a smaller version of that.[lol]this is just a gaming pc, but the one i have now, always loses save games,or gets corrupted.so i was trying to build[my first build]a failsafe pc for cheap.impossible[lol]so i think im going to buy the drives sam told me about[which by the way going on sale tomarrow:2 x drives for $79 usa dollars each at newegg.com, 160gb sata 3.0 x 2=320 storage, with faster writes and not failsafe at all].then im just going to put them in raid 0[the cheapest way out]that should give me the best performance.i wanted to ask you about cd/dvd burners.is it better to buy sata drives?or does any cd/dvd drive do the same thing really.are the read and writes that much of a difference between sata,ide,and ata?the board im going to get is the abit 939 fital1ty motherboard at newegg for $202,has 4 /raid 0 slots and i thinks 2 sata 3.0 slots on the board.i have been reading the reviews and this board has all the extra. exspecially the guru panel,reset the bios by pressing a little button on the 5.25 drivebay,its unbelieveable.how many times have you crawled into your pc to change jumpers,no more with this bad boy.peace thanks
