This edition of our e-newsletter has something of a 'hard drive focus', featuring as it does a fascinating opinion piece from WD's Matt Rutledge on how disk drive technologies must evolve to keep up with data centre demands, as well as a news announcement from WD subsidiary HGST about the company's newest HDD offerings. These devices combine two technologies that only a year or two ago seemed to be a long way off 'real world' use: HelioSeal is HGST's ingenious method of sealing the HDD in a helium-filled enclosure for massively improved reliability and longevity, while SMR ('shingling' of data tracks) allows ever higher densities. The new UltraStar Archive Ha 10TB HDD is the first HGST product to combine both technologies for use in the enterprise.

As Matt Rutledge argues, 'web-scale' organisations are facing entirely new storage parameters: "Enterprises have been slow to adopt top capacity drives because higher areal density penalises performance while high platter counts impact cost-per-gigabyte. In archival disk storage, though, slowing performance is acceptable if the counterbalancing rewards are preferable. Consideration of these variables reveals a sweet spot in the market ideal for archival disk with five platters in a one inch-high format. In fact, the five-platter form factor turns out to play particularly well across several data centre segments with both high- and low-intensity workloads." It looks as though, as Rutledge suggests, some HDD manufacturers are now identfiying that 'sweet spot' in the market and targetting it very smartly.
