WHAT IS A SOLID STATE DRIVE?
Solid State Drive (SSD) is a data storage device like our traditional
Hard Disk Drive (HDD).
In SSD, the primary storage medium is through semiconductors
rather than a magnetic media such as HDD.

ORIGIN OF SSD
EARLY SSDs:
1950s- Era of vacuum tubes – but discontinued.
1970s & 1980s- Implemented in Semiconductormemory for early superconductors.
1978- Texas Memory Systems -a 16KB RAM SSD – used by oil companies.
1979- Strong Tek- First modern SSD.
1983- Sharp PC-5000- 128KB SSD storage cartridges.
1986- Santa Clara Systems- BatRam- 4MB. 1987- EMC Corporation – SSD for mini-computers.

FLASH BASED SSDs:
1995: M-Systems -Flash-based SSDs- Were HDD
replacements by military & aerospace industries.
BITMICRO- 1999- 18GB 3.5”SSD.
Fusion- io –
2007-PCI e-based SSD- 100,000IOPS- capacity 320GB.
Dec 2009- Technology announced the world’s first
SSD using a 6 Gbps SATA interface.

http://slidepdf.com/reader/full/2solid-state-drive 11/13
FEATURE SSD HDD
Reliability No moving parts, less chance formechanical failures. Subject to mechanicalfailures.
Performance Near zero latency seek meansfaster response times and betterperformance.
Mechanical operation addsto seek times and limitsresponse time.
Durability No moving parts makes SSD muchmore resistant to shock andvibration.
Excessive shock and orvibration can causemechanical failure.
Power Requires less power whencompared to HDD.
More power required andhigher performance HDDs
will consume more powerthan consumer gradeHDDs.
Density 32-160 GB, currently limited toNAND density
Up to 1 terabyte (1024 GB)HDDs are available now.
