After connecting the CD311 with the host PC, the LCD screen displays an appropriate icon indicating the device is ready.

The PC's operating system (XP in our case) recognized the new HDD as APACER ShareSteno USB Device.

Our HDD was formatted with FAT32 files system and had two partitions. At this point, the user can browse the folders and move or copy files from and to the CD311 from the host PC. Remember that the CD311 is also a portable HDD device with 40GB capacity :-)

Both partitions are formatted using FAT32,

In order to test the device's performance, we removed both partitions and used HD Tach for both reading/writing tests.

The performance, according to HD Tach was very good, with Average Read/Write of 27.0/24.2 Mb/s respectively. The random access time was around 17.6ms, while at BURST mode, the USB2.0 bus reached 37.1MB/sec. As you can see, the CD311 uses the full capacity of the USB2.0 bus with very good reading/writing performance.
