Bij Thresh's FiringSquad hebben ze een vergelijking in elkaar gedraaid tussen SCSI en IDE en wat de voordelen en nadelen van beide zijn.
Natuurlijk erg handig als je zelf toch al twijfelde over wat je zelf wilde gaan gebruiken.
Hier alvast een stukje uit het artikel over de snelheidsverschillen tussen SCSI en IDE:
So, when we talk overall about the all-encompassing word "performance", we have to also break this down into more manageable pieces. IDE and SCSI performance with single and dual drive configurations will not differ by much. Although the SCSI interface does have that extra command overhead that we talked about, SCSI performance in a single configuration is by no means going to lag far behind IDE. However, when we want to use more than one device on an IDE channel, though, we see that SCSI performance will be much better than IDE. The partial fix for this is by utilizing both of the IDE channels, but then expansion is limited. By no means, though, should anyone fall into marketing hype and believe that Ultra-2 Wide SCSI is going to give you 80MB/s, or that a drive that has SUPPORT for Ultra ATA-66 is going to be able to sustain any transfer at that rate.
Depending on the personal configuration that you have, or see yourself having, IDE may be a fine solution. If you don't have the need for multiple device support right now, but see it being a possibility, then SCSI should be a big consideration, because of the expandability that it offers. This, of course, is a separate issue in itself.
