Long description

The horizontal axis has the following marks: 1 KB, 4 KB, 16 KB, 64 KB, 256 KB, AND 1 MB. The left vertical axis is labeled Data Rate (MB per second) and ranges from 0 to 60 in increments of 10 units. The right vertical axis is labeled Disk space utilization and ranges from 0 percent to 100 percent in increments of 20 units. The first dotted curve starts from (1 KB, 0), moves linearly to the point (12 KB, 0), then raises upward like a concave upward, and increases linearly until the point (1 MB, 60) on the left axis and (1 MB, 100 percent) on the right axis. The curve passes through the following points: (16 KB, 1), (64 KB, 10), and (256 KB, 25). The second curve starts from point (1 KB, 80) moves horizontally until the point (12 KB, 60), then falls as a concave up curve, and ends at the point (1 MB, 0) on the left axis and (1 MB, 0 percent) on the right axis. The curve passes through the following points: (16 KB, 15), (64 KB, 5), and (256 KB, 1).
