FireDisk Taurus: External Firewire-800 RAID Storage Benchmarks

FireDisk Taurus™ technical specifications

FireDisk Taurus™ Typical Performance

Files transfer speed from or to FireDisk Taurus™ will depend highly on the performance of the computer receiving or sending the data. Following figures are provided as an indication.

They have been measured in typical user’s conditions, with big and small files, using a 1TB FireDisk Taurus and a computer with the following specifications: CPU AMD 4200+, 2GB RAM Dual Channel, 1TB (2 x 500GB at raid 0 ) HDD SATA internal drive, Windows XP SP2, Unibrain ubCore drivers (v. 5.12), Unibrain FireBoard-800 1394b PCI adapter.

FireDisk Taurus™ Typical Performance (MBytes/sec, indicative mean values from multiple measurements)

Interface	Big File Copy		Small Files Copy
Interface	Read	Write	Read	Write
FireWire 800Mbps (1394b)	71	63	58	64
FireWire 400Mbps (1394a)	65	65	60	60
USB 2.0	33	34	29	33

Important Note: With Service Pack2, Windows XP does not provide full native support for FireWire800. The maximum performance is limited by the operating system to 100 Mbps as soon as a 1394b adapter or 1394b device is detected.
To achieve full 800Mbps support, installation of Unibrain’s ubCore™ FireWire Drivers is required.
