No data on the second question. Actually, you could make a Terrabyte with about 13 to 14 75GB drives. It would cost a fortune, but a high-performance setup with SCSI drives could fit in your standard household closet with plenty of room to spare. I have no doubt that No Such Agency has the largest data installation in the world. A TB of storage isn't that much.
Life is good.
A TB of storage isn't that much. I've seen the 180 GB barracuda scsi, twould be nice. I think Seagates 180GB SCSI drive is the biggest single drive. Greets from Hell, the Dark-Knight. Man would take a long time to defrage the whole thing.
