I have this setup.
ProAvio 8MS with mini-sas,
8 1TB Western Diginal Caviar Black Drives,
and the Highpoint Rocketraid 4322 (mini-sas).
I built the system about a month or so ago. Initially I had purchased Western Digital’s Enterprise class 2Tb drives, but those drives use this ‘intellipower’ feature which cause just enough lag to screw up HDCam layback, so I returned them for the 7200 RPM Caviar Black drives. That said, just yesterday Hitachi claimed to be shipping 2Tb drives and, if so, that’s pretty tight. I would still rather see benchmarks on these drives and let them ‘go out into the wild’ for a bit before I purchased them. After buying bleeding edge drives twice now, I’ve learned my lesson.
Regarding the comments to Highpoint, i’ve only used their cards for the last 4 years – so I have no other product knowledge to compare it to. I have never had a drive or RAID die on me using highpoint products. I have, however, run into situations where a card I had was no longer compatible with my OS (moving from Tiger to Leopard required a new controller card – Highpoint wouldn’t release drives for Leopard with my older card – that ticked me off). I did, however, run 4 400 gig hitachi drives in RAID 0 from 2004-present (the raid still works, I gave it to an employee).
With the 1Tb drives, the 4322 performs well. I run in raid 5 and my aja system test is routinely around 600 write and 500 read. There are little spikes and dips in the graph, but it’s fairly consistent throughout. For approximately 2k, I’m extremely please with this system that I built myself.
Mounting the drives is a fairly standard procedure. The Highpoint rocketraid interface sucks. The instructions are vague and you have to experiment with building it correctly.
For help on the navigating the interface, google this:
“super fast 4Tb raid for under 1500”
I will say I much prefer the mini-sas vs esata. It’s 2 cables vs 8 really short cables. If you can go the min-sas route, I say go for it. Highpoint’s customer service and support is non-existent. I would have purchased a CalDigit card, which everybody says are the best, but they get in a tizzy if you use somebody elses drives and enclosures, so I gave my business to Highpoint. David’s advice about the ATTO is probably dead-on, I have no knowledge of it, but I can tell you that it’s not the hardest thing in the world to build your own RAID these days. I saved some money and learned how to build a RAID array. That knowledge is invaluable.
Good luck!
