72 TB X4540?

No, this isn´t an announcement about a new flavour of our storver, but i started to think of new capacity jumps at hard disk with the Thumper/Thor factor in mind: Segate announced an 1.5 TB harddisk … such drives would give the X4540/J4500 a capacity of 72 TB. One and a half rack for one Petabyte … and in the case you use the 32 MB Cache flavour of the drive you would one and a half gigabyte worth of cache on the disks alone. Wow …
