RAID 0 vs RAID 1? - Page 3

post #21 of 22
It has all been addressed, but I thought I would still add my thoughts. I go with RAID 0 for performance, and have my important files coped to other hard drives. RAID 1 is more for business applications where you are protecting from mechanical failure, and do not want any down time (one drive fails and you get a warning to replace the bad drive, but the server keeps operating).

Raid 0+1, Raid 5 and RAID 10 use more system resources, and therefore need a dedicated card.

If you are a general PC user who wants performance, I recommend going RAID 0 and extra drives. At least this is from my own personal experience. And I've tried the dedicated RAID cards, both the Perc i5 and i6, and found myself going back to the onboard for RAID 0. After all, with Windows 7 you can make a complete system image, even in RAID, and recover that image to a new set of RAID drives... as long as the new drives are the same capacity or larger.

If you're trying to speed up your system, raid also isn't the answer. You won't notice any "speedup" from higher sequential speeds, which is what raid gives you. The only purpose to raid (when it comes to speed) is to speed up the transfer time of large (we're talking gigabytes) files.

So:

-are you going to be transferring large files frequently and need increased speed?
-do you need your computer to be running 24/7 and never turn off for backups?

If the former is true, consider raid 0 or raid 10. If the latter is true, consider raid 1 or raid 10.

If neither is true, you probably won't see any benefit from raid and might want to consider a solid state drive instead of that second drive.

as to "-are you going to be transferring large files frequently and need increased speed? " ...yes, if you scroll up i watch alot of movies, and do alot of movie editing of my own, i work with files of multiple gigs.
