Two makers of perpendicular magnetic recording (PMR) platters for hard disk drives (HDDs) said recently they had started to produce platters with leading capacities that enable creation of 1TB hard drives for desktops as well as up to 320GB drives for mobile computers.

Both Fuji Electric Group and Showa Denko K.K. (SDK) this week said they had begin shipments of 334GB platters for 3.5” hard drives as well as 160GB platters for 2.5” HDDs to their customers. The 334GB platters are already utilized by Samsung’s SpinPoint F1 hard disk drives, but unfortunately it is unclear whether 160GB platters are already used by the companies’ customers.

Potentially, 160GB 2.5” platters allow creation of HDDs for notebooks with 320GB capacities, which is 70GB more compared to currently shipping drives from companies like Western Digital. Still, makers of hard drives usually do not format platters to maximum capacity due to yield reasons.

Mass production of high-capacity platters enable leading producer of hard disk drives to create larger-capacity products, which essentially decreases pricing of currently shipping products and allows end-users to store more software, media and other types of data.

Come on, NOONE needs such capacities in a notebook.
These guys are totally missing market demand.
Persons that use software that needs such capacities are either using a tower PC anyways (because of the performance needed that notebook still cannot match) or are using external HDD arrays since such amounts of data need to be secured in RAID arrays (RAID5 preferrably).

What the market really needs are higher performing hard drives. 2.5" drives really are lagging behind with average rotation speed at about only 5000 rpm (most are 5400, then 4200, then 7200).

A HDD with only one of those 160 GB platters would be perfect, since it would allow for 7200 rpm operation easily.
