Samsung Unveils M80 SATA Drives

Samsung Electronics has added the M80 SATA Series and M80 Series to its 2.5 inch hard disk drive offerings for notebook and enterprise computing applications. Both series utilize advanced perpendicular magnetic recording (PMR) technology, feature an optional free-fall sensors and offer increased storage capacity, now up to 160 GB. The M80 SATA Series features the 80 GB HM080HI, the 120 GB HM120II and 160 GB HM160JI. The M80 Series includes the 80 GB HM080HC, the 120 GB HM120IC and the 160 GB HM160JC. The M80 SATA Series and M80 Series are said to be Samsung`s first hard drives based on PMR technology. Unlike traditional longitudinal recording technology, which lays data bits end to end where they can flip and corrupt data on the disc, PMR technology places the data bits perpendicular to the disc, which reduces the corruption factor. In addition, by placing the data bits standing on end, more data can fit onto a disc, allowing for greater storage capacity. With PMG technology, users can fit up to 40,000 MP3 songs and 160 hours of video on a 160 GB drive. The new 2.5 inch drives offer increased damage risk protection by incorporating free-fall sensors. Samsung s free-fall sensors are located on the hard drive, not the notebook s motherboard. The drive offers are also equipped with the Hybrid Latch System, a mechanism that eliminates unpleasant rattling noises and significantly reduces the clicking noise generated when a drive moves its heads on and off the disk according to the operating modes.

Six Steps to ILM Implementation

Many things can spur a company to kick off an ILM project, but two reasons lead all the rest: a desire to implement storage tiers to reduce costs and the need to align corporate I.T. practices with regulatory compliance demands. There is no need to do ILM if you do not have to, though the odds are, you do. Stage 1: Identify the need. First, determine whether your company`s data is answerable to regulatory demands. If you work for a U.S. company, this likely means checking out the California Privacy Law Compliance (SB1), Gramm-Leach-Bliley, Health Insurance Portability and Accountability Act, Real Estate Settlement Procedures Act or the Sarbanes-Oxley Act. If you do business in Europe, also check out Basel II compliance. This is complicated stuff, and no one expects an I.T. manager to know about it. Immediately set up a meeting with someone in your legal department to discuss this. Large organizations have compliance officers who are there for this sort of discussion. Be prepared to learn that the list of regulatory requirements above does not begin to scratch the surface. Second, determine whether your company uses its storage in an optimal manner. If you have lots of data online, some of which is quite old, and if you have only one kind of storage, there`s a good chance that high-value and low-value data are intermixed at your site. That`s a pretty good indicator that you need to re-examine your storage strategy. Keep in mind that if your shop is run according to service-level agreements and you frequently fall out of conformance with those objectives, something is very wrong. If either of the above typifies your situation, go on to Stage 2. Stage 2: Define your ILM strategy. Understanding the value of data lies at the heart of ILM, so this raises the question of...
