[ML-General] hardware RAID

[david]

With the data transfer speeds of the 3+ GB SATA, even a single SATA 
drive can keep up with HD video recording using a BlackMagic converter.  
But, even 2 Tb will fill up -fast- with HD video.  :) I've not tried 
compression in real time to see if it works.  So even in software, raid 
0 is working ok but if the same hardware controller can do both 
simultaneously, I might as well; else just get 2 controllers as the raid 
sets are in different machines.

Maybe it is not raid 5 for mirroring, but I thought it was.  Of course, 
pot ruined my memory back in 1968...  Anyway, mirroring is what I want.

In Linux, I use the everyday mdadm for mirroring, without LVM.  Oh yeah, 
Ubuntu, Fedora, and Debian.  Got real tired of Suse long ago. I miss 
Slackware.  :)  (now RedHat I think.)


Aside but related: I'm strongly considering a mirrored network disk 
array.  Maybe mirror two of the new 6TB drives.  Maybe one of the Linux 
machines (with the newer mobo w/6Gb/second data rates) could host the 
network array.  (VideoMonster will still have the striped disks 
internally but I wouldn't mind having it able to access a central disk 
system at the same time.)
