We having been doing performance optimisation on optical drives. These are particularly sensitive to transfer size and we would like your advice as to which adapter card would give us the largest possible transfer size. We have noticed between 3.0 and 4.2 the standard transfer size has changed from 128KB to 60KB. After some experimentation we have taken Adaptec up to 256KB but Symbios only goes to 128KB before we have problems. Could you help by advising us on the adapter that will allow us to use the largest transfer size for each SCSI operation ?
