I feel like I should chime in on this thread as a contributor to this forum. Please let me preface by saying that I do not mean to start a forum war and I am not trying to be difficult. I don’t have as much experience as Bob, Ramona, and Marco and you should respect their comments highly, but I do have something to say about my SATA experience. It really depends on how much time you want to devote to down time and fixing what’s wrong. Read into Bob’s post about the non mounting drives, now imagine that you are under a tight deadline and the client is sitting their looking at their watch thinking “am I paying for this time?” while you figure out which of the eight ports is not quite seated, and restarts, and try-agains, and all you need to do is output your beautifully finished 30 second spot out to tape and get it to distribution or fedex in an hour. Don’t get me wrong, SATA performance is totally surprising and I think one day in the not so distant future, SATA raids will be the ‘it’ storage solution. If you don’t mind some weirdness and supporting your own hardware with no one to call, I say go for it. you can’t match the price/performance. I had a 4 disk SATA RAID with a HighPoint rocketraid card (it was before sonnet had even the 4+4 let alone the eSATA) and I had all sorts of problems that almost kicked my ass into not working for this particular group of folks again. I had two rocketraid cards melt on me and their support was awful. it took almost a month to get a new card to replace the first faulty card. Much to my chagrin, I had to buy another one in the meantime and that one ended up going bad as well. I finally got the replacement and decided that I was going to look into an external RAID that was built professionally and also professionally supported because I was fed up. I got a small 5 disk 4Gb fibre raid and have not looked back. It works great, handles 720p UC HD in RAID 3 and is totally expandable into future systems. That being said, maybe Sonnet’s support is much better than HighPoint’s and perhaps their SATA cards work much better. I don’t know what kind of in house engineering support you have, but I am an owner operator and I have myself to take care of my machines. Buying a prebuilt, pretested RAID has been a great move for me. It hurt a little more up front in the pocketbook, but has saved me soooo much time and stress, and as you know time is money. Also, I have the comfort of knowing that if something goes wrong I make a phone call and can have a brand new shiny RAID or a replacement drive in the morning if something catastrophic happens.
Please take this for what it’s worth as my story is probably unique. Many people have great experiences with SATA Raids.
Whichever route you choose, I hope it brings success.
