WD1200JB 120GB - Page 4

SCSI Mechanic Linear Reading/Writing Tests

We performed the SCSI Mechanic tests as described in our test methology guide. The test results are illustrated in the following graph. Note that the measurement unit is the Kb/s:

The performance for the WD1200JB in the "Sequential I/O" reading test was around 38Mb/s, which is high enough for your A/V needs. The drive communicates well with the IDE bus, and delivers 86690Kb/s at the "Same Sector I/O" test. Lastly, in the "Random I/O" test, the performance is 12961Kb/s higher than what Maxtor 6L40J2 gave.

In the linear writing tests, the WD1200JB drive performed also very well. In the "Sequential" test, the drive gave 37848Kb/s. In the "Random" test, it has 15693Kb/s and in the "Butterfly" test, 23858Kb/s. WD1200JB is faster than any 40GB drive.
