2.3  Data Transfer Rate Performance Results The next eight figures are graphs of the data rate measurements. The first four figures (Figures 2.1 - 2.4) are for writes and the next four figures (Figures 2.5 - 2.8) are for reads.  Each figure sets forth data throughput for a different compression ratio. On each figure there are three curves one for the 160 MB/sec SCSI interface, one for the 1 Gb/sec Fibre interface and one for the 2 Gb/sec Fibre interface. Notice that in each figure the SCSI interface is a little faster at small block sizes; but for large block sizes the data rate is the same for the 2 Gb/sec Fibre interface.   Figure 2.1:  IBM Ultrium 2 Writes, Compression ratio 1:1 Figure 2.2:  IBM Ultrium 2 Writes, Compression ratio 2:1 Page 5 of 10 p1   p2   p3   p4   p5   p6   p7   p8   p9   p10
