Each observer is expected to provide his/her own external disk drives for transporting spigot data away from Green Bank. The spigot produces approximately 1 TB of data in 10 hours. If you wish to have a backup copy of your data, you must provide the disk for that as well. Writing to tapes is not an option due to the considerable amount of data produced in a spigot run. For plugging in external disks, the the spigot computer can handle outputs using FireWire 400, USB 2.0, and Serial ATA. The write speed to the USB2 is currently the slowest, and to the SATA disks the fastest. Lacie (www.lacie.com) makes reliable external disks in various sizes (250 GB, 400 GB, 500 GB, etc.) To insure hassle free observing and saving of your data, it is a very good idea to send your disks to Green Bank well in advance of your observing sessions. Finally, to insure your disks are readily locatable, and that all your various plugs and cords are returned to you, please clearly label your external drives and all cords with your name and a unique number. If you don't do this, we may not be able to guarantee the return of all your hardware. Further information on external disks and data storage capabilities can be sent to Chris Clark (cclark) or Wolfgang Baudler (wbaudler). All email address here should have @nrao.edu added at the end.
