I see from the glossy "Sun's Low-Cost Mass-Storage Options" that the synchronous-SCSI bus is capable of 4 Mbytes per second, but the table on the back page specifies burst transfer rates of 1.2 and 1.5 Mbytes per second for the 104MB and 327MB disks. Does this mean that one can obtain much better I/O performance from a system with two 104MB disks than from one 327MB disk even though the latter has faster access times and higher transfer rates? If true this would mean that the most effective disk upgrade option for a network of SPARCstation 1's is to configure each SS1 with two 104MB drives before considering any deskside storage. Comments?
