TDK Japan, a supplier of read-write heads for hard-drive manufacturers predicts that 2.5 hard drives will be a reality by late 2009, and will reach markets by early 2010. The company presented a roadmap to the press late last week, that shows that it will have the technology available to produce 3.5 inch disk platters with 640 GB data density. Four such platters will go into making 2.5 TB drives. On the 2.5 inch drive front, the roadmap shows a jump to 320 GB per platter density, which allows 640GB 2-platter SFF drives to be announced by manufacturers towards the end of this year.
Hard Drive manufacturers had reached the 2 TB milestone earlier this year. Seagate and Western Digital used four 500 GB platters in their products. At this rate of data density increases, a 5 TB hard drive in 2010, as predicted by Hitachi's Yoshihiro Shiroishi last year, sounds a little more realistic.
