which raid do i use

[MassiveOni]

heya,

i want to get another 2 1tb hard drives and raid it with the one i have, but i want to have the 3 1tb's as 1 1tb, but it striped over 2 of them, and the 3rd will be the backup.

which raid is it?

and can i use 2x 1tb sata3 wd black (striped), and a 1tb sata2 wd green (backup)?

thanks

You could mean RAID5; which has one parity disk. But generally that's a RAID level to avoid on Windows, especially with software implementations ("fakeraid").

If you have Intel chipset (ICH10R for example) then you have Intel RAID controller which is the best of all onboard RAID; it can do RAID5 moderately well.

Just know that RAID is no backup; and RAID5's reliability is one on paper and one in reality; those two have some distinct differences. Always invest in a real backup solution if you do not want to lose your files.

By the way; 1.5TB and 2.0TB are cheaper per byte stored. Perhaps you could buy two new 1.5TB and keep the 1.0TB as backup?

heya,

i already have 1x 1tb (wd black sata3) and 5x 2tb (wd green sata2)

but i was going to add another 1tb (wd black sata3) and for the raid backup have a 1tb (wd green sata2)

i have a gigabyte ga-p55a-ud4p motherboard, that has a hardware raid controller on it.

thanks

No it does not. It has a fakeraid/software controller. The board would cost at least $600 if it had a true hardware raid controller with battery backed cache. Although as sub.mesa did say Intel has descent fakeraid.

heya,

ahh ok, think is the first time of me thinking about using raid,

i think i might just replace the 1tb with a 600gb raptor.

thanks

Why?

You can get significantly faster performance out of a SSD than a Raptor.
