How is raid perform compared with triditional drives?

taking a guess....you mean how does raid work with standard hardrives?

RAID - Wikipedia, the free encyclopedia

raid 0 is mirror...backing up. Raid 1 is stripping which makes them faster but only in the sense of transfer rate...from what i remember. Also you loose a small amount of reliability with raid 1. Two drives is not that bad but more drives you add the chance of a error/fatal error grows by a lot...not saying exponentially because i dont remember the formula...its in the wiki.

 

actually raid 0 is stripping, not real raid, and raid 1 is mirroring

raid 0 - strips a file and put in 2 drives, if any of those fail for any reason, you will lose the file or more, usually more, for every drive you put in the array the chance of failure grows by 100%

raid 1 - mirrors the drive, i.e. you put a file in drive 1, and it will be in drive 2

 

ops yea my bad i got them switched....are you sure its 100% i remember it being some special algorithm. can't look it up this second

 

Mathematically? No.

See http://forum.notebookreview.com/sol...orage/633747-raid-not-raid-2.html#post8256333 for more details.

 

I'm also going to throw this out there, simply because it needs to be said. RAID1 is NOT backup. It's a measure to ensure that you don't lose data in the event your hard drive crashes and is only a short term protection mechanism. It does not protect again user error, viruses, corruption, etc. You still need to make regular backups on an external hard drive or NAS.

 

^^^^ THIS 10000%

I used WHS with RAID 1 + backup to another WHS with folder duplication enabled with critical data backed up to an external HDD and cloud storage.
