The nice thing about it being recognized as scsi is because you can dynamically unload the scsi driver (in case you need to hot-swap the drive), and then reload it. The IDE drivers of 2.4 have to be statically linked in, and that's a pain! Besides, the scsi subsystem has more prime-time exposure to hotswappable devices (and you need that for RAID) than the IDE subsystem which is always under flux. > > > If 2.6 can natively support SATA drives (maski walang RAID), I can > > always use it with Linux software RAID. > > That's my point, even 2.4.x can recognize SATA.

I trust the linux kernel RAID implementation more than any firmware based raid....or non open source driver which is what promise has. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
