Hitachi hard drive is one of the main hard drive brands nowadays, IBM(later Hitachi) is widely known in data recovery business for their line of DeskStar HDDs also known as DeathStars. These hard drives, mostly DTLA and AVER families, became infamous for their reportedly high failure rates. It is believed their problems were mainly connected with glass platters – new technology introduced by Hitachi in these hard drives.

SAS-Serial Attached SCSI SAS will continue to build upon the established SCSI technologies that are typically used in RAID and other enterprise environments. The emerging interface uses the existing SCSI protocol, while featuring serial point-to-point interconnections, dual porting, increased addressability and full duplex operation. SAS is set to deliver a maximum data transfer rate of 3Gbit/s, with a roadmap to 12Gbit/s.

When computer users whether personal or business think of losing data, they fear hard disk crashes, power failures, physical damage, and other unavoidable occurrences. These problems can cause valuable data to be lost, running up expenses of hundreds to thousands of dollars.

Hard drive wipe is not new to us, while the data security awareness doesn’t keep up with this concept. And the public are still wondering how to erase the sensitive data, just cast aside or use free hard drive wipe software is ok enough; or professional hard drive wipe tool should be employed. How important it is to erase data?

SAS-Serial Attached SCSI , an evolution of parallel SCSI into a point-to-point serial peripheral interface in which controllers are linked directly to disk drives. SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0Gb/s. In addition, SAS drives can be hot-plugged
