Compared to hard disk drives, Solid State Storage Devices have no moving parts, which have generated the common held belief that the data is much safer on these. However, this is not the case as SSDs have higher vulnerability, compared to HDDs, to some defects that typical such as abrupt power loss, magnetic fields and electric charges.
Data loss in flash media and solid-state drives is most commonly cause by:
|
Accidental physical damage |
|
Power interruption to the device causing electronics failure
and/or data corruption |
|
SSDs were introduced on the market a few years back and are depicted as the technology meant to replace HDDs. Unlike HDDs, where platters and writing / reading heads are used, the SSDs use flash memory and the writing / accessing of data on the drive is done simultaneously on multiple flash media through various complex algorithms meant to maximise their speed. |
