tnx Sir. more observations: -tried to mount /dev/ram* but the size (97mb) has to be adjusted at boot or sysctl which i haven't gotten yet. -tried /dev/shm but the maximum filesize is 32bit address which is just a little lower then the size of the iso. (i'm using 32-bit ubuntu) -doing a 'cat a3mphilippines.iso > /dev/null' takes 1 minute the first time and less than 2 seconds thenafter. --this also inflates the cache size in 'top' from ~500mb to ~4.8gb. which means filesystem cache works. so no need to ramfs or /dev/shm -as with iostats i can only see some 36mB/s read in sda while writing at 4x with 7 writers. don't know why i can't see the stats for the other writers. -also the usb-sata is not very reliable even in windows & nero, at least for writing dvds. same with the pci-ide&sata card. maybe because they are both sata1.0 only? --so i exchanged one of my sata dvd writers to an ide one. the cdrking usb-ide is more reliable than their pci-ide-sata and usb-sata adapters. -assuming dvdwriting at 4x uses 5.5mB/s, i can still add a lot more usb-ide writers to the 6 usb ports and maybe use usb-hubs if needed, before using up all the 266mB/s(?) of southbridge bandwidth, even if the computer becomes very sluggish while writing with all 8.
