Plextor UltraPleX PX-40TS SCSI CD-ROM

2. Data Tests

Plextor PX-40TS SCSI CD ROM - Page 2

Data Tests

Test Method:
I used CD Speed 99 v0.41b, SCSI Mechanic v2.1h (evaluation version) and SiSoft Sandra 99 v3.5.0 to run Data tests. I run all tests with Sync Data Trasnfer On & Off . All tests done with the same CD.

CD Speed results:        (Speed : Bigger is better,  Seek Times : less is better, CPU Usage : less is better)

Verdict of Data Tests:
Plextor 40x really gives what it promises. Average transfer rate is 4.7Mb/S and max is 6.5MB/s . As for seeks time it is really fast with 83ms (random). Also since it is a scsi device it has low CPU usage. You have to ebable Sync Data Tranfer for making the drive work in max speed..How good is the performance ? (comparing to other CD Roms..) Into past i had made an roundup between 3 drives (Teac 32x, Plextor 40x, Phillips 48x). If you go there you will check that Plextor performed good..
