We have had several cases of hard drive failure. In some cases it has meant total loss of the data.
Conventional drives are not "hard" - in the sense of being robust and reliable - and the name comes from the days of floppy drives. The magnetic medium which spins around is made of highly polished aluminium or glass, turning at extremely high speed; some reach the equivalent of 170 mph!
Great for fast access since there is a fast moving head going back and forth just a minute distance above the disk. But a knock or jolt for the laptop could mean the end of the hard drive and the data within.
ScanDisk unveiled their latest product at the Consumer Electronics Show 2009 . In a year when attendance was down and with no major goodies catching the media's attention, this little device made the headlines.
In her CES report , Ilse Jurrien states:
"The new SanDisk pSSD-P2 and SanDisk pSSD-S2 SSDs have capacity and performance for more full-featured netbooks which require a robust operating system. Designed as drop-in replacements for hard-disk drives (HDDs), SanDisk’s new second generation module has a SATA interface to meet new netbook design requirements. The SATA interface offers a significant boost in performance rendering these SSDs faster than HDDs in critical aspects. Booting and launching applications takes just half the time of an HDD."
