Since about 9 months, 2.5 inch notebook drives ship that have 500 gigabyte platters.
With that technology, these drives ship:
- 1 platter of 500 gigabyte into the 7 mm thick Hitachi Travelstar Z7K500
- 2 platters of 500 gigabyte into the 9.5 mm thick 1 TB drive: Samsung M8 HN-M101MBB or Western Digital Scorpio Blue 1TB WD10JPVT (both compared at NotebookReview)
they easily could manufacture these configurations:
- 3 platters of 500 gigabyte into a 12.5 mm thick 1.5 TB drive
(the currently only available 1.5 TB notebook drive is 14.8 mm thick: Seagate ST1500LM003) - 4 platters of 500 gigabyte into a 14.8 mm thick 2 TB drive
this one almost fits a MacBook (people buy an incase cover to make the MacBook even to fit the 14.8 mm thick drive)
