Sander Sassen van HardwareCentral heeft een review getikt van de erg stoere Plextor UltraPlex 40x Max SCSI CD-Rom speler. Hieronder wat meer info over zijn performance:
Upon looking at both screenshots we see that the 12/20 Plex has a sequential read speed of 1897 KB/s, whereas the UltraPlex 40X Max has a sequential read speed of 2840 KB/s. That’s a 2840 / 1897 = 50% increase in performance. Also take notice of the spindle speeds, these are just estimates, but I can tell you first hand that the UltraPlex spins really fast; the spec sheet mentions ‘over 8000 RPM’ and I think that is very realistic.
If we look at the random read speed, we’re looking at a 622 / 560 = 11% increase in performance. Take notice however that the drive’s mechanics are working against the odds here, as the laser pickup unit now has to move back and forth across the CD’s surface and thus it is limited by its mass and the speed and strength of the drive motor. Mounting a bigger drive motor or just making the pick up lighter might seem like a way to tackle this problem, but in reality won’t quite cut it; with all laser pickups it is a trade off between speed and precision. So an 11% improvement is a nice accomplishment.
