For my home system, I prefer % symplicity and robustness and performance, so I tend just use RAID1 I've finally convinced The Boss to spring for additional disks so that I can mirror, so our two servers both have SSD mirroring; yay. The web server doesn't need much space, so it has a pair of 4T HDDs mirrored as well ... but as RAID10 since I thought that that was cool. Ah, well. % mirrors of all my disks. I really don't have all that much stuff I % need lots of disk space for. And for that I have a scratch volume. [snip] Heh. Not only do we have scratch space on diskfarm, but that's where we have 30T-plus of data that continues to grow with every video made. Mirroring just won't do there, both because I'd have to have little chunks of mirror and because I don't know that I can convince her to pay for THAT much storage (plus plugging in all of those drives). We need RAID5 there ... but the devices are just really frickin' huge. Thanks & HANN :-D -- David T-G See http://justpickone.org/davidtg/email/ See http://justpickone.org/davidtg/tofu.txt
