I am looking for some kind of external RAID that I can boot from. There's a few options: 1. eSATA bracket plugged into motherboard; LaCie 4big 4x1 TB external. 2. CalDigit HDelement or HDone. The HDelement feels a bit cramped for the price ($1500 for 4 drives). I really like this solution from a simplicity perspective. I don't care that the card locks me into CalDigit. The HDone is more interesting, but more than doubles the price of entry at $4000. 3. Some kind of mixed vendor solution, e.g., RocketRAID card + some kind of external chassis. 4. Something + Sans Digital 8 bay enclosure. I have a 2 bay Sans Digital case and it's quite nicely done. The 8 bay enclosure is cheap at $300. It comes with a RAID card that is known NOT to work with modern Mac OS X, so it would need some kind of RAID card in front of it. But what? 5. I don't really care if my Mac can sleep or not, since sleeping disrupts my VMs, so I never let it sleep anyway. 6. I don't care about internal drives. I'd rather have external. 7. I have a Drobo Pro for Time Machine. It's great, but not fast enough for what I'm trying to get done. I also have a Drobo Elite for other purposes, which might be OK, except it's not bootable. 8. I think $4,000 is my upper limit on this, though the cheaper the better. Thoughts? Is anyone using the LaCie as a bootable RAID by plugging into the motherboard SATA? Any ideas what the performance of this thing is? Not that excited about LaCie in general, but willing to give it a go.
