I actually just installed a box that has three 17.5gb SCSI drives in it. It's using software raid at the moment and working fine.
I didn't know you could do RAID-5 in software. But if it can... great, although the individual user demands will determine the real need. If speed is important, the onboard processor in a hardware RAID card (for calculations and rebuilding) will be a _big_ bonus. Also, in cases like mine where you want/need lots of drives, the internal connectors are simply going to run out on you. :-)

What do you need all that space for???
The idea is to put 12 disks (120 GB each decimal, 110GB binary) on the controller. One disk is kept for a hot spare, and a second disk is the parity drive, leaving you with about 1.1TB of useful--and hopefully ungodly fast--space in your array. Then I gotta learn LVM since I figure at that point I really will need it.
As to what the space is for:
* Roughly 120GB for mirrors: Red Hat Linux, TLDP, Aurora Linux, Shorewall, RULE Project
* Roughly 400GB for music in WAV format, ripped straight off my CD collection so I have a massive jukebox
* Roughly 50GB for music in MP3 format, encoded from the WAV files every night (these will be used for mixes in the car, for playing on the notebook over the wireless link, etc.)
* Roughly 300GB reserved for future video, both backups of my movie DVD's and storing the videos my wife takes to torment the baby
* Roughly 50GB of backup in user files
All of this leads me to believe that it's reasonable to forecast around 930-950GB in use (150-170GB free) within the next two years or so, and this looks to be the cheapest, safest, most reliable way to get it. Just takes time to save enough money to buy all the disks... got the RAID controller and six discs already.
