2x60GB @ 7200rpm [Raid 0] vs. 2x80GB SATA @5400rpm [Raid 0] - Page 2

I have a 250GB file server that mirros all of the important data from the various PC's that I have in the house. Additional to that, I have a 160GB External IEE1394 HDD that is used for a second/third copy of the real important "stuff" like videos that I am making. Then there are those really really really important things that I also copy to either a 20GB or 40GB 2.5 USB HDDs. Overkill, one might say, until they lose everything the day before sceduled delivery. OH, I also have another LINUX server that I keep some "stuff" on - mainly the passwords and software that I have purchased as "downloads". Backups are kind of like Money - you can never have too much. Just don't try to backup anything that can be rebuilt without a problem aka Windows O/S.

In my experience RAID-0 configs are no more prone to hardware failure than a single drive config.
While it is true that a RAID-0 array is just as error prone as a single very fast drive, it is riskier than 2 non-RAIDed drives. If the 2 drives are not in a RAID configuration, then one failure will mean that you still have half of your total data. Of course, in practice, this is not so because most programs will probably be on 1 drive and most data on the other.

Still, the chance of losing ALL your data with 2 separate drives (both drives failing simultaneously - simulating the failure of 1 drive in a RAID-0 config) is less than the chance of a losing all your data with 2 RAIDed drives.

Should have replied to this two weeks ago -sorry!
You statement is not quite true. With a single drive, you can drop it into any computer and use any of a variety of recovery tools. With RAID 0, you need to use the same computer, the matching drive, etc. Also, some (many? few?) recovery tools may not work.

IMHO, the risk is far too great to justify a miniscule performance increase.

I'm glad you made that point--it was my thinking exactly, but I didn't know for sure.

I'm still planning on getting RAID 0, but I'm glad you clarified that there is, in fact, an increased risk.

Thanks.
