Compared to a standard DVD, Blu-ray's 50GB of storage capacity seems fairly large. Nevertheless, companies have continued to look for ways to squeeze more data onto a single disc. Along with the multi-layer discs developed by Pioneer, Hitachi and TDK, companies are now looking at partial response maximum likelihood (PRML) signal processing as a possible way to store up to 33.4GB of data per single layer. Thanks to Sony and Panasonic, PRML is one step closer to becoming a reality. The two companies recently announced that they've developed a new evaluation technique known as i-MLSE (Maximum Likelihood Sequence Estimation) that can be used to judge the optical quality when reading and writing to 33.4GB media.

Sony and Panasonic Corp. resolved this by developing the i-MLSE (Maximum Likelihood Sequence Estimation) evaluation index. Details of i-MLSE were announced at International Symposium on Optical Memory 2009 (ISOM '09), held in October 2009. The first of the two key characteristics is that i-MLSE has a strong correlation with the error rate (Fig. 1) even in read/write at 33.4 GB using PRML. The second, according to Sony, is that "i-MLSE exhibits the same relationship to signal quality as conventional jitter." In other words, it will be relatively simple to estimate the read error rate from the i-MLSE, just as can be done now with jitter.

In the digital age, people are creating and accessing digital content like never before. As such, they require a storage device that is powerful enough to store and serve this content, but friendly enough to manage quickly and effortlessly. Today, digital storage leader Thecus® Technology is proud to announce the Thecus® N4200. Fast, secure, and incredibly easy-to-use, the N4200 is the ideal home NAS for the digital lifestyle.

The N4200 was designed to enable users to access their data both quickly and easily. It begins with the new Intel® Atom™ dual-core processor D510, which runs at 1.66GHz and, in combination with 1GB of DDR2 memory, delivers both blistering data transfer speeds and increased system response. Users can easy manage their unit with the N4200’s dual displays. The LCD offers a wealth of system information, including hard disk and network status, while the big and bright 2.8” OLED display allows users to modify a number of settings directly on the device including WAN, LAN, Link Aggregation, languages and more, making the N4200 the friendliest Thecus® NAS ever.

A-DATA Technology, the world leader in DRAM modules and flash memory products, launched the industry first ever combo flash drive N002 that features the dual interface of USB 3.0 and SATA II, designed to maximize data transfer speed to the ultimate. Adopting the industry-leading 8-channel architecture, N002 is able to boost transfer speed tenfold compared to ordinary flash drives with USB 2.0 interface by delivering up to ultra-fast 200 MB/s and 170 MB/s in sequential read/write performance respectively.

Ready to hit the market by January, 2010, N002 makes USB 3.0 a reality. It supports all latest platforms that come with USB 3.0 ports, while also being backward compatible with USB 2.0 ports at a lower speed performance. Available in 64GB, 128GB and 256GB, N002 is ideal for users who are thirsty for super-sized storage capacities with unrivaled speed via the innovative USB 3.0 and SATA II dual interface. A combination of speed, storage and portability altogether into one device, N002 is by all means the most effective solution to access and transfer large amount of data, including high-resolution images, multimedia files and whole lot more, at an instant and on the go.
