If you want to glean optimal write performance from your drive, activate the "Write Cache" checkbox on the "Guidelines" tab under "Drive Properties" in the device manager.
As the following data-transfer diagrams show, it is well worth it to activate this feature.
When write cache is deactivated, the transfer rate hovers at around 1400 kB/s.
Examining the curve, you can see that the disk is read (and written) from the outer to the inner edge. Since the medium spins at a constant speed, a steadily declining data-transfer rate results. The jump in transfer rate at the 325MB mark can be attributed to the fact that both sides of the medium are read/ written in turn from the outside in.
If the write cache is activated, the write rate of the drive averages out at almost 4000 kB/s. The read transfer rate averages at just shy of 5000 kB/s.
The maximum transfer rate of 50x or 7.3 MBytes/s promised by the manufacturer could not be achieved using this synthetic benchmark.
The maximum write transfer rate we got was 5059 kB/s (= 4.9 MB/s). The burst rate for reading was 6356 kB/s (= 6.2 MB/s).
