Reading a few files from the same tape

Four files were read from the same tape. All file were between 1.1GB to 1.5 GB large. For the first file (most likely) the tape had to be remounted. The file was read twice the first time from disk and the second time from the disk cache. The figure below shows the effective transfer rates for the transfers and the time difference between reading from tape and disk (first-second). The position of the files on tape is also shown.
