Hurry it up!
I've got sixteen drives in my home server, and I really want to bring that down.
Analysis Toshiba is looking to boosted flash and disk capacities to grow storage revenues and help returned the troubled company to growth. In a July 6 in-house presentation investor relations briefing by Yasuo Naruke, President and CEO of Toshiba’s Storage and Electronic Devices Solutions Company, information was revealed …

I thought this useful right until I saw the Toshiba price per drive data in the first chart. Their SAS enterprise drive clocks in at around $30,000, based on $30/GB. That may be Toshiba's system price, but it beats even EMC's massive markups.
SATA SSDs good enough for enterprise work are around $300 (forget all the enterprise and near-line hoopla). That's Dell's price for such a drive! The differential sort of makes mincemeat of Toshiba's whole presentation.
So in the next five years the capacity is forecast to increase by around 50%.
This contrasts with the doubling of capacity/density with each new generation not so many years ago.
If data use is growing faster then this means demand must be going up, or am I wrong?
Well, helium being a very light gas (only hydrogen is less dense), is obviously dust and moisture free and is also chemically inert. As a result the lifetime of the drive should be a lot longer and also friction within the bearings is lower so self heating is less of an issue.
I've also read somewhere that if hydrogen were used there would be deleterious effects on the data layers as H2 can induce cracking in some alloys.
Incidentally helium is also apparently used in Philips LED light bulbs to conduct heat from the "filament" to the outside air more efficiently.
