Since you compared SCSI and IDE drives back then, SCSI hardware has also gotten better. ( its probably still easier to connect an external SCSI device, than it is to add another internal IDE device ) Major improvements have probably been in - motherboard data bus ( width in bits, speed - Hz, and chips to manage the bus ) - adapter hardware ( SCSI and IDE chips and adapters ) - improvements in SCSI and IDE 'protocols' with increases in speed and buswidth - physical system memory ( for most of us ) = - operating systems like OS2 ( which use the system CPU and memory to transfer data via data and device busses to your physical devices ) Now you have IDE with Ultra DMA BUT you also have SCSI adapters which will support mind boggling data transfer speeds, and a huge number of devices. At least, whether you use a SCSI or IDe device, you should be able to get the job done.

IDE or Floppy controller attached tape drives are, in my experience "flakey" at best. Irrespective of which Operating System is in use. They're simply not worth the aggrovation! Now you could consider other media than Tape. Especially if speed is a factor. Castlewood has you released a 5.2 GB version of their removable disk storage solution. DVD-RAM and DVD-R are also options. If you use any of these options you won't need the Back again software as you can address these as a normal drive and a simple scheduled Xcopy or Zip will do the job. Since you bought Warp Server for e-Business, I'd recommend you look at the Warp Server backup program that is supplied with it. It hasn't been publicised but it is a very good full backup solution supporting most SCSI tape drives as well as local and LAN harddisks, optical drives, floppies (Hmm, I wonder how effective THAT is ?) and ADSM connections to midrange and mainframe systems. I use it here with my Sony DDS Drive (SCSI of course). Cheers/2 Ed. Dr Graham Norton FRACP Neurologist wrote: > My question is are the current IDE tape drives now just as reliable and efficient?
