archiving as opposed to backing up

Funny you should say that Sellam. I've been thinking a bit about their business model since the topic came up. If they're using RAID 0+1 (adequate and cheaper than RAID 5 for this application), and assuming they use "street" 73GB SCSI hard drives, then, ignoring the processor the drives are connected to, it would cost them over $400 for 73GB worth of drives (a pair for 0+1, SCA), but they're selling it for less than $150. And that doesn't include the cost of the SAN, bandwidth, etc. SAN manufacturer-branded drives are even more expensive usually. I wonder where and how their economy of scale is that makes it work. Maybe they're picking up Network Appliances from eBay. :-) There was an earlier comment about multiple data centers; doubtful, with these economics. Patrick
