Plasmon UDO30I external SCSI Drive - Page 3

Reading Tests

Using the RW cartridge, the UDO30I operates like a Removable/Floppy device using UDFS format with a 5.25" cardridge. Blank media requires a quick format before use. For the test we copied 6,129 different files, large and small, from the RW cartridge using drag & drop, to our hard disk drive. The reading time is listed below while the total bytes was 13.6 GB.

The sequential read test was achieved with the SCSI Mechanic 3.0 utility with the RW cartridge full of different types of files. We let the test run for 30 min. in order to obtain more accurate results.

.

Average read transfer rate is 6.45MB/s and the maximum is 8.57MB/s.

Using AnalyzeDisk's IPEAK utility from Intel, we measured the average access time needed when reading from the drive.

The Distribution of Read Service Times test uses a large number of samples, 25,000 to be exact, and measures the time taken for random single sector read requests across the entire drive's surface.

The average access time is 61.7 ms

Random reads gave us what can be considered high access times for read access at 61.7ms when compared to a hard disk for example.
