|
 |
One of my hd drives just died. I lost 120gb of data (mostly non backup'ed).
So now I'm thinking about buying two new disks and making a RAID 1, but is it worth it?
I believe it's faster for reads, but is the difference (in speed) noticeable? Like when booting the OS, or loading a map in a game?
Also(on a different situation), is RAID 0 worth the cost/risk?

You have to choose a RAID which meets your specific demands of performance and data recovery. That will take atleast 4 disks though I don't remember which raid number it is. Plus a hardware (software version is the sux) raid controller.
Personally I am not so sure if the performance gains would be so much what with people having more than 2GB of RAM in their computers these days. I would go for the two disk version which is nothing but a 1:1 mirror copy.

raid 1 is only mirroring, no speed-gains
raid 0 is striping, double the speed, double the risk of losing your data, because if one drive fails, both data-sets are gone
the best in most home-pcs is raid 1+0, but requires 4 drives, two mirroring, two striping
in better raid-chips you also get versions were you have a number of drives plus one parity drive (e.g. raid 5), where you can have the benefits of both speed and security with three drives or more.

RAID1 seems to actually have read speed's gain.
"Increased read performance", " Twice the Read transaction rate of single disks, same Write transaction rate as single disks".
cf. http://en.wikipedia.org/wiki/RAID#Standard_RAID_levels

@ deelix
Yeah a lot of mobos with nforce/intel chipsets have it, but not necessary with a lot of RAID levels.

when i bought my first raid-card it, that wasnt the case, so thanx for the info. I thought it didnt change, but it makes very much sense that read-speeds can be faster in a raid1 setup

I got my 2 raptors (in raid) only because of Online gaming (BF2/2142) but I dont play that anymore sorta...well sporadic. But it makes a hell of a difference when spawning in to a map as you will load up the map faster then most ppl, well that is if you have good ping and what have you. I am running raid0 and I use Acronis True Image to back up my C: drive/drives  once a week...keeps me happy!
