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?
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:
|Cyl x Hds x Spt||RPM||Transfer Mode||Average Read Seek|
|16383 x 16 x 63*||7200||66.6 MB/s||9.0 ms|
Next up for comparison was a SCSI Western Digital Vantage 18.3-GB hard drive. The specs for it are as follows:
|Width/Height||RPM||Interface||Average Read Seek|
|3.5-inch/low profile||10,000||Ultra / Ultra2 SCSI||6.6 ms|
For a more detailed analysis of these two hard drives, visit the Western Digital Web site by clicking Western Digital Caviar or Western Digital Vantage.
