RAID 0: Striped: best performance because data is written across strips simultaneously: single point of failure RAID 1: Mirroring. 50% reduction in disk space eliminate single disk failures RAID 5: parity: slower but you can get up to 80% effective disk usage.
You can add hot spares to RAID 5 and maybe raid 1. You can also do combinations RAID 0+1 At 06:32 AM 10/1/2002 +0000, you wrote: >Maybe you would know... >what are the differences between the different levels of RAID? >I would imagine that having striped drives would be bad for performance in >this case, I would think that having the files as sequential as possible >would reduce latency in searching the different drives for the file... but >maybe I'm wrong.. what does raid 5 do that raid 0 doesn't? > > >>From: Sam Ockman <[EMAIL PROTECTED]> >>Reply-To: [EMAIL PROTECTED] >>To: Christensen Tom <[EMAIL PROTECTED]> >>CC: [EMAIL PROTECTED] >>Subject: Re: hard drive performance >>Date: Mon, 30 Sep 2002 23:24:51 -0700 >> >>Raid 0 should give you great performance. >> >>-Sam >> >>On Tue, Oct 01, 2002 at 04:11:16AM +0000, Christensen Tom wrote: >> > >> > I am wondering about hard drive performance with large files. >> > namely large video files/video editing. >> > I have 2 120GB hard drives, I want them to appear as 1 volume, >> > performance wise would RAID or lvm be better? >> > if RAID which level 0-5?? >> > >> > >> > >> > _________________________________________________________________ >> > Send and receive Hotmail on your mobile device: http://mobile.msn.com >> > >> > >> > >> > -- >> > redhat-list mailing list >> > unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe >> > https://listman.redhat.com/mailman/listinfo/redhat-list >> >>-- >>Sam Ockman, Chairman and CEO >>Tel: 415-358-2600 Fax: 415-896-6742 Toll Free: 888-PENGUIN >>Penguin Computing - The World's Most Reliable Linux Systems >>www.penguincomputing.com >> >> >> >>-- >>redhat-list mailing list >>unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe >>https://listman.redhat.com/mailman/listinfo/redhat-list > > > > >_________________________________________________________________ >Join the world's largest e-mail service with MSN Hotmail. >http://www.hotmail.com > > > >-- >redhat-list mailing list >unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe >https://listman.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED]?subject=unsubscribe https://listman.redhat.com/mailman/listinfo/redhat-list
