If you can afford DAT, that's the way to go. Travan is designed for workstations while Travan NS is for small netwoks. Breakeven point between DAT and Travan is about 15-20 tapes. After that, DAT gets cheaper. Forget AIT. You've seen ads for AIT2 for the last year. Have you seen an AIT2 tape anywhere? Sony is apparently having beaucoup problems coming up with media. The only AIT2 media is about 72GB, not even close to the 100GB it's spec'ed for. DLT is a good technology for servers. SuperDLT is pretty much the end of the line, though. They'll have to pull one big rabbit out of the hat to come up with anything after that other than minor incremental improvements. If speed and capacity are a higher priority, check out LTO, http://www.lto.org. Multiple vendors for the drives and media means no shortage of replacements. Cross-compatibility is part of the spec, so interchanging data is much less of a problem than it has been in the past. Ecrix, Onstream, etc. all suffer from the same problems: new vendors with little tape experience, no future roadmap, single sources, proprietary technology. BTW, yes, I work for Seagate. > You might look at AIT and DLT but they're still too expensive. Would > overstock or refurb units be OK?
