EIDE vs. SCSI hard drives
This is a debate that every support tech has heard before. Which is better, EIDE or SCSI hard drives? In the past, the clear winner has always been the SCSI hard drives due to their speed and versatility. However, with the onset of faster, larger, and definitely cheaper EIDE hard drives, does this rule still hold true?

In comparison
I decided to compare specs on two Western Digital hard drives. The first one was an EIDE Western Digital Caviar 20.5-GB hard drive. Its specs are as follows:

Table A
Cyl x Hds x Spt RPM Transfer Mode Average Read Seek
16383 x 16 x 63* 7200 66.6 MB/s 9.0 ms
Table A shows the specs for Western Digital’s EIDE Caviar 20.5-GB hard drive.

Next up for comparison was a SCSI Western Digital Vantage 18.3-GB hard drive. The specs for it are as follows:

Table B
Width/Height RPM Interface Average Read Seek
3.5-inch/low profile 10,000 Ultra / Ultra2 SCSI 6.6 ms
Table B shows the specs for Western Digital’s SCSI Vantage 18.3-GB hard drive.
