Data Tests

- SCSI Mechanic v3.0x results

The AOpen CRW3248 is the definite winner at the SCSI Mechanic tests, since it has the highest performance of the competitor drives. The drive has an average of 5514Kb/s when reading pressed CDs, due to its increased 48x maximum reading speed. The CyberDrive CW058D follows with 5367Kb/s and LiteOn LTR-32123S, Mitsumi CR-480ATE and Philips PCRW3210 follow. At the random I/O tests, the LiteOn LTR-32123S holds the first position with 895Kb/s. AOpen CRW3248 follows with 889Kb/s, Mitsumi CR-480ATE comes third with 837Kb/s, CyberDrive forth with 752Kb/s and Philips PCRW3210 last with 665Kb/s.

Even both AOpen and CyberDrive have 48x maximum reading speed; AOpen is faster due to its increased start/end speeds.

The AOpen CRW3248 continues to perform very well and gives the lower random seek times. The drive has a 89ms random seek time, while LiteOn LTR-32123S comes second with 93ms. The rest of the drives (Mitsumi, CyberDrive and Philips) gave seek times higher than 110ms.
