I don't know what they cost off-hand, but the upper end of this product line looks nice, up to 12 drives on one 64-bit controller. They also make a newer serial ATA RAID controller, but those drive are more expensive although I wonder where they fit on the price/performance curve...? Hum, darn - no hot-swapping on these. Anyone else got some better hardware links? g'nitey Ben On Wed, 23 Jul 2003 16:13:17 -0700 Bob Miller <[EMAIL PROTECTED]> wrote: | Larry Price wrote: | | > We have an argument going here in the office regarding how to spec a | > storage array for a high volume, low-latency production server that | > would need to hold and serve approximately 1-3 TB of maildirs | | Is the requirement to use maildir format nonnegotiable?
