The original SCSI bus was released in 1984. Over these 20 years SCSI was up-graded a number of times raising it's throughput from SCSI-1 @ 5MB/s to 160MB/s for SCSI-5.
Any way I was updating web pages today based on when they were lasted reviewed. About half a dozen SCSI bus pages showed up with dates of 12/12/06. So I decided to take a look and see if those pages required an up-date ~ remember standards work stopped on a number of older SCSI standards [so the facts aren't changing].
I took a look at the SCSI page hits year to date, by month, and I noticed that the pages were only getting a few thousand hits combined. So 12 related SCSI bus topic pages only received 12,000 page views this year. That is real low for a major computer interface.
However; Serial SCSI [Serial Attached SCSI, or SAS] was released in 2003 which moved from a parallel interface to a serial interface ~ identical to SATA. The Serial SCSI interface jump the through put speed to 3Gbps, using a smaller cable.
So I realize the Parallel SCSI is in decline, but it seems that the trend is showing a massive decline, as shown in the chart.
Of the two main Hard Disk Driver interfaces [HDD], SCSI seems to be taking a harder hit then the IDE interface [ATA Bus] ~ which is also obsolete. The SCSI bus was also more expensive to implement than IDE, and SCSI tended to be integrated by high-end users so it stands to reason. Work stops on the SCSI standard and at the same time starts up on a new faster Serial SCSI ~ so you have no up-grade path. You have to move to the new Serial version of the bus.
IDE shows a hugh decline too, but not as massive

3/4/08, just checked the incoming hits or page views for the main SCSI bus interface page, 1,187 page views from 11/02/07. Maybe 15 hits/day, with 30 hits on better days. However; even looking out to 1/1/07 I see the same incoming traffic. 2006 was just a bit better but only by a few clicks. No wait these numbers are for Serial SCSI [SAS].
I just found that the SCSI page did not have the tracking java code for Google Analytics, so traffic to this page was not being counted. The code has been posted in now.
7/27/09 Even as Google Trends indicate a drop in searches. Google Analytics indicate page views for the SCSI page are kind of flat, but down a bit.
Analytics also indicates that this blog page has only sent one visitor back to the main site.
