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.

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..
