For the record, we are using 3 western digital 7200rpm 27gb drives. 50gb is used for DNEWS spool, the rest for tucows mirrors (Less the OS of course) > > I work for an ISP.

Quite a difference. We are also ISP's. According to C&W, and UU Net, a full feed is about 12gb a day. From what I have heard, (and experience) that's pretty much the norm in the US. I had always heard that the European feeds where much bigger. How much history do you keep? With 50gb, we manage to keep about 5days worth of binaries, and about 30 days worth of everything else. > The IDE drives, IMHO, won't be able to cope with this feed. We didn't think the IDE's would work either.. until we tried them. Check out the I/O numbers on the new 7200rmp IDE's vs older SCSI drives. The fact of the matter is that SCSI drive's will alway out perform IDE's. It's all in what you do with them. We have 3 T1's going to/from the news server. Even really old IDE's will stand up pretty well to 4.5mbs throughput. There is one other feature of DNEWS that I didn't mention. It has really good anti-spam features, like the ability to block via a filter file, and the ability to set limits to crossposts. You can even set it to delete the crossposts when the original message expires. We use a really agressive filter, and block about 20% of the binararies coming in. -- Bob Martin, bob@buckhorn.net http://www.buckhorn.net "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones." -- Albert Einstein To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
