Hi Mitch –
Several SATA controllers have issues. Some work, some don’t, some are not reliable. Some take up too much space.
The bottom line here, is that the new Sonnet Tempo X eSATA 8 port card is just not reliable enough yet to recommend yet. I saw this card working at the ProMax booth, but in my own tests, and from what I heard from others, the reliablity is not there yet. Sometimes the drives mount, sometimes they don’t.
YES, you can use 2 SATA drives to do 10 bit SDI uncompressed, and now G Raid and Lacie are selling these (about $800 for 800 gigs including the controller card from Initio, but this is a 2 port card). I have not tried this yet, but I absolutely will try this.
Reliability is everything. I have a customer using a Sonnet Tempo X 4+4
with excellent results, but not in an 8 way stripe configuration. All the 8 way stripe configurations that I have tried with sonnet cards have not been reliable yet, although when they do work, they outperform anything on the market.
So I will certainly persue the new Lacie and G Raid SATA soltions (you can use anything). I cannot deal with the Highpoint 1820A rocket raid, as it still only has internal connectors, and the pass thru card takes up an entire slot, filling up the G5. For SD SDI, the new SATA solutions should be tried, as they are CHEAP, and more than enough for uncompressed SDI, or
DVCProHD. But for uncompressed HD solutions, at this time, I must still
recommend using the HUGE U320RX, as the only reliable solution (sorry to you
Apple XServe RAID owners).
