: Large Directory Backup - Driver Tweaks"> Both the USB and PC Card-attached drives were set to "Optimize for Quick Removal" in the Device Manager by default. We changed settings of the USB drive to "Optimize for Performance", but left disk write caching disabled, as shown below.
The following shots show the ExtremeTech 2002 subdirectory copy for both the USB and PC Card devices with the Optimize for Performance setting. You can see here that the PC Card version finally moves ahead, as data is able to be blasted across the PC Card interface from the Windows disk cache faster than across USB 1.1. Sure, we wish we had a USB 2.0 notebook to compare, but not this time.
Next, we tried the Enable Write Caching on Disk in addition to Windows disk cache for the PC Card-attached drive and scores actually went down a bit. As you can see in the results below, the drives own disk cache seems to get in the way for mostly write operations. But wed need a lot more experimenting with different scenarios to make definitive conclusions here. We also wanted to see the effects of defragging the drive on the USB results, and they were largely similar, given our drive wasnt terribly fragmented to begin with. We may perform further testing with the write verification option enabled in the future, but for now, were satisfied that the drive performs adequately and is very stable in operations.
