Question : Hard Drive

Instead of purchasing one Raptor HDD which is like 72GB would it be better to use that or buy 2 7200 RPM SATA 250mb drives and run them in a RAID 0 array and get nearly double the performance of the drive.

Which is suggested to have better results?

 

[Nitestick]

well the 2 drives in RAID 0 should outperform a single Raptor but there is a higher chance of failure and data loss.

yeh 2 in RAID.. or to be on teh safe side get a raptor but id rather have 500GB than 75GB...

well the 2 drives in RAID 0 should outperform a single Raptor but there is a higher chance of failure and data loss.

you mean theres a higher chance of failure and data lose in raid0? by the way 2x 250gb hdd in raid0 = 500gb? or 250gb?


ps. why would there be a greater chance of this, this is the first time i have heard that.

 

[Nitestick]

in RAID 0 500gb. and there is effectively double the chance of failure when you are using RAID 0 as if either of the drives fail you lose all data in the array.

hm, but for storage I would use one single 320gb hdd, and for the windows and games I was thinking of using 2 hdds in raid. I dunno mayb I would get 120gb each for those. so even if I lose I only lose the part with the games (which can be replaced) and the os but the only thing was I was under the impression that in raid 120+120 would =120 because the 2 drives acted like one. that is what I thought, am I wrong?

 

[Nitestick]

they do act as one but you are confusing RAID 0 with RAID 1.

ok so from what im seeing raid 0 is that it will take peices of the files and save them half on the first hdd and the other half on the second hdd, then what does raid 1 do? and whats the difference in speed ?

 

[Nitestick]

RAID 1 gives no improvement in performance but it provodes redundancy. the second drive is a realtime copy of the first so if the first fails it has a complete backup

 

[KlNGPlN]

lol, wait you jus said if one fails, the only data gets lost as well, so how can one be the backup of the other?
