Explanation

SSDs (Solid State Drives) store data in NAND flash memory chips - they have no moving parts whatsoever. Traditional mechanical hard drives (including IDE/PATA and SATA drives) use spinning magnetic platters and a moving read/write arm. Physical shock can cause the read head to contact the platter (a 'head crash'), destroying data and the drive. SSDs are immune to this failure mode because there is nothing to crash. This makes SSDs far superior in shock-prone environments such as laptops, rugged devices, and portable storage. IDE and SATA describe interface/connection standards that can apply to mechanical drives. NAS (Network Attached Storage) is a network storage solution/enclosure type - not a drive technology - and can contain either HDDs or SSDs.
