SCSI Help!!!!!!!

[tinman101]

Could someone please explain the Different types of SCSI. Am confused as to what will run with what and whether each different type needs it's own controller card or whether 1 controler card will run several different types. Am biulding new system and would like to have an SCSI drive for the video capture and am in need of some education. Which type would be the best for this application and what brand of controler card would be the most economical but would RAID and 2 speedy HDs work just as well?

scsi raid is extremely expensive, you are still limited by the internal transfer rate however, which is the same for ata100 and scsi, there is no real diference, you get better seek times in scsi (a lot better) I notice a difference in that, you will gain more bandwidth in a stripe raid array with scsi than an ata100 array. depends on what you are going to be doing with video capture, unless you are planning on say streaming extremely high quality movies over a gigabit nic or something, I would just stick with ata133 or ata100

building a system with all scsi can be very expensive, good luck

You get better seek times and better concurrent access speeds because SCSI was made to handle many disks at once, but IDE was barely made to handle 2. Each SCSI disk can disconnect from the chain to give the others time to use it while it finishes it's access, IDE can't do that so any IDE access locks the whole chain. Plus you can have a RAID array of up to 14 disks per card if you can afford it =)
