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.
