IDE, SCSI And Recording Everything

In the past SCSI beat IDE hands-down but now according to Simson Garfinkel, "today's IDE drives are significantly faster than SCSI drives". In the article at O'Reilly Network he talks about the tests they had run for storage of network data on disks. In the light of this article does anyone see any reason for going with SCSI in a desktop machine? For servers with heavy disk usage patterns it might be different due to command queuing." Disk types aren't what the article's really about, though -- it's a top-level look at network forensics (including advice on building a traffic-analysis system), and makes some interesting points about the unbalanced growth of storage and bandwidth.

Speed by CmdrTaco+(editor) · 2002-05-02 08:00 · Score: 2, Troll

IDE may be faster than SCSI in some benchmark tests, but in multiple drive machines where IDE drives share controllers, SCSI will always be faster. Plus, access times and transfer speeds aren't everything. The fact that SCSI supports multiple IO commands at the same time is a major contribitor to the feel of speed.
