Writing Tests

The write test involves copying 6,129 different large and small files to the RW cartridge using drag & drop and measuring the time taken. The time for writing is listed below while the total bytes transfered was 13.6 GB.

Sequential write test carried out again with SCSI Mechanic 3.0 and the RW cartridge full of different kinds of files. The test needed 30 minutes.

Average write transfer rate is 9.8MB/s with a maximum transfer rate of 24MB/s.

To measure the average access time needed when writing to the drive we again used AnalyzeDisk.

The Distribution of Write Service Times test, takes 25,000 random single-sector writes and measures the average access time it takes to writes across the entire drive's surface.

The average access time is 87.65 ms

Write access time of 87.65ms is far higher than the company's specifications.
