Solid
State Disk (SSD) could soon replace the Hard Disk Drive (HDD)
The Solid State Disk (SSD) has the potential to replace Hard
Disk Drive (HDD) technology in the very near future. For
all mobile applications, but in particular for notebooks,
netbooks and mobile internet devices, it has strong advantages
compared to HDD.
The key advantages of the SSD technology derives from the
fact that there are no more mechanical, moving parts involved.
Simplified, mechanics is replaced by silicon. Basically
this technological step is similar to the way in which portable
CD players were replaced by NAND Flash based MP3 players.
The SSD also consists of NAND Flash components as they are
already widely used in memory cards, mobile phones, MP3 players
to mention just a few. However, the interface of an SSD is
compatible with the presently used HDD interfaces.
As one of the leading NAND Flash inventors and manufacturers
Toshiba holds all the key resources in its hands and strives to
fully discover the benefits of SSD.
SSD advantages against HDD:
Reliability
No moving parts means a much higher crash-resistant drive
compared to today’s HDD. In particular for mobile usage
scenarios such as notebooks, netbooks, handhelds and mobile
internet devices this is extremely important. No more crashing
heads, squealing bearings, shattered platters and thus
productivity loss. An endurance of 1 mio hours MTBF for a
MLC-based SSD underlines this advantage.
Performance
No spinning disks or searching heads as a HDD. SSD
wastes no time booting a system. Read/write speeds are well
above comparable hard drives. Boot up far quicker and load
applications almost instantly. Launch presentations and
movies at nearly not time.
Cost Effectiveness
Hard disk drives seem inexpensive compared to Solid State
Disks, but are they really? Considering the frequency of
HDD crashes plus the related costs for replacement, repair and
data recovery as well as lost productivity you may realize that
SSD can save money in the long term. Just imagine the
notebook HDD of a sales representative crashes. How long
is he offline? How much does this cost the company?
Also the shorter booting and shutting down times of SSD increase
the efficiency of the mobile work force.
Durability
Shock, vibration and temperature the three risks for every
mobile device. A SSD is capable of surviving some of the
most hostile conditions on Earth: A summer day in a hot car of a
sales man or a hard landing on an airport floor. NAND
Flash memory chip based solid state technology makes surviving a
hard fall more likely and therefore the data more safe.
Power Efficiency
Get more time before you have to recharge. SSDs require
less energy than a conventional HDD. In particular the
idle power use is much lower as no mechanical parts need to be
moved. On top no energy is wasted by heat emissions and
thus a fan to keep it cool
