Network speed:
Although MyBook Ethernet-capable disks come with a Gigabit Ethernet interface, the network speed is significantly slower. Especially for older "blue rings" models (200Mhz ARM CPU and 32 MByte RAM), where it varies between 3–6 MByte/s, with an average of 4.5 MByte/s.[4]. The newer "white lights" MyBook World Edition 1TB and 2TB models, WDH1NC and WDH2NC (oxnas810[5], 380 Mhz ARM CPU and 128 MByte RAM), compare to USB drive speed at about 10MB/s write and 25MB/s read.[6].
Using a performance-optimized copying software, such as FastCopy[7], enlarged TcpWindowSize on WindowsXP ("TCP tuning") and enlarged network MTU size ("Jumbo frame") enabled on both MyBook and Windows, a "white lights" WDH1NC achieves ~36 MByte/s reading and ~18 MByte/s writing speed for Samba/CIFS access over Gigabit Ethernet.
