HGST Goes Self-Assembling Molecules
HGST has announced that it has developed self-assembling molecules and nanoimprinting to potentially double data density in hard disk drives.
HGST used to be known as Hitachi Global Storage Technologies before Western Digital bought it, and has been working on lithography techniques to boost data density on hard disk platters. Now the firm has announced that it has been able to create patterns of magnetic islands that are 10nm wide, doubling present state of the art data density.
HGST Fellow Tom Albrecht described the self-assembling molecules as block copolymers that are made of segments that repel each other to create segments that are lined up in rows, and said that lab tests show promising read/write performance and data retention. The firm claims it has combined self-assembling molecules, line doubling and nanoimprinting down to the 10nm scale in a circular arrangement.
Albrecht said, “We made our ultra-small features without using any conventional photolithography. With the proper chemistry and surface preparations, we believe this work is extendable to ever-smaller dimensions.”
HGST said self-assembling patterning and nanoimprinting can result in 1.2 trillion dots per inch, which it claims is twice the density of existing hard disk drives. According to the firm, its engineers have been able to create segments only 50 atoms wide.
Although HGST showed off the technology this week at the SPIE Advanced Lithography 2013 conference, the firm said it expects the technology to be cost effective by the end of the decade, that is if solid-state disk drives haven’t eliminated the need for hard disk drives by then.
WD Going 5TB Next Year
According to Russian website Almodi.org that managed to snag some screenshots of WD’s plans for the next year, it appears that Western Digital wants to bring 5TB drives in both its Green ant the Red Series in Q4 2013.
In addition to the 5TB WD50EFRX Red series and the WD50EZRX in the Green series, the Q3 2013 will also bring 4TB drives in both series. Of course, we are talking about 3.5-inch drives that will feature 64MB of cache and SATA 6Gbps interface.
The slides also do not reveal any info regarding standard 3.5-inch Blue series and 2.5-inch Scorpio line of drives. As you may remember, WD has recently announced a 4TB version in its Black series lineup so 5TB one might come sooner than in the Green or WD Red NAS line.
Western Digital Goes Red
Western Digital has announced a completely new WD Red line of hard disk drives designed specifically for home and small office network attached storage (NAS) devices.
Standing shoulder to shoulder with WD’s Blue, Green, and Black series, the Red series offers 3.5-inch HDDs available in 1, 2 and 3TB capacities and are designed for NAS systems with one to five drive bays. As noted, all three models will be packed in a standard 3.5-inch form factor and feature SATA 6Gbps interface and 64MB of cache.
According to WD, these HDDs have been compatibility tested with top NAS box manufacturers and optimized for both power and performance, which is, at least according to WD, a much better way to go considering that consumers had to choose between desktop or high-end server drives for their NAS devices, with neither being cost effective or fully NAS compatible.
According to WD, the new Red line feature 3D Active Balance Plus enhanced balance control technology feature that should significantly improve overall drive performance and reliability.
Western Digital Debuts 2TB Passbook HD
Comments Off on Western Digital Debuts 2TB Passbook HD
Western Digital is about to introduce a 2TB My Passport Essential series external drive. According to some early listings, the new 2.5-inch drive should set you back just over $200.00, more important is that it seems like a pretty interesting external drive.
It measures 110x83x18mm, so we assuming this is a 12.5mm drive and as such it won’t fit into most notebooks. However, as an external drive it is second to none. It features USB 3.0, but it won’t be the fastest thing around, as it is a 5400rpm unit.
