Well, I was talking with a guy about servers the other day. I was a bit shocked whenever I asked him if there was any significant difference between SCSI and SATA and why he always uses SCSI. (note, I'm not sure if by SCSI he meant SAS)
He told me that SCSI is always faster and that the drives are always more reliable.. I mean, this seems like a bold statement.
He told me something about how SCSI will always be faster than SATA because the OS sends the SCSI (controller?) a request to get a file and it will build the file inside of the SCSI controller, instead of searching all over the disk.. which I do not understand how that would work, so I figure it is BS.
SAS and SATA currently have equivalent data rate speeds..
Is there any true backing for his reasoning that SCSI is always faster and more reliable than SATA?
