Here are the important speedvalues for this drive in direct compare. The
ROMarks, which are valued by the access time
and the exact average speed valued by the transfer rate
The graphics show, that the drive has no problems with CD-Rs. Other
drives, as the Mitsumi FX 4820 for example, have enormous problems with
CD-Rs and the speed decreases up to 80%. In the test the Cyberdrive 482D
is faster at blue CD-Rs than at the original CD. The minimum access times
are smaller at CD-Rs than at the Original CD. But the Average speed for
Original CDs is a little bit small with 19-fold. The Mitsumi-drive (a
48-speed too) reaches a value of 24,3-fold.
The Cyberdrive is a very balanced drive, that distinguishes with its constance
irrespective of the CD-type. This aspect is very positive.
The error correcting ability of the drive is very good, too. The drive
switches fast to a lower speed and increases the speed after the error.
This behaviour is ideal. The benchmarks underline this fact. We cannot
establish a deficit.
Copy of an Original CD:
In this testfeature we copied a full CD to the harddisk drive and
stopped the required time. The work of the drive is excellent. It needs 3
min 33 sec, a really toptime. The drive works audible fast and copies many
small files in a little time. In comparison with the Mitsumi drive
(nominal same high speed) it is about 5 minutes faster! This is really an
excellent result.
Summary:
In the speed section the Cyberdrive 482D belongs to the top drives. A
little corporal defect is the low average speed at Original CDs, but in
the rest it delivers constant very good values and impresses with a fast
CD-copy to the harddisk drive. It is general noticed, that the drive gets
soon very loud. This is a criterion for that it gets soon to high speeds
and therefore delivers good values
