Dollar for dollar, IDE has far better performance. Even including the
cost of extra controllers (because you need one controller for each
drive), I can get four high-end IDE drives for the price of one SCSI
drive. There's no way any SCSI drive is going to do as many I/Os per
second as four good IDE drives.

As well, seek time isn't always important. For your log disk, for
example, you care more about high sequential write speed.

What makes you think it won't be easy, in my case?
