Key benefits and recommendations for SSD drive installation and use.

1. Categories of drives and theirs types.

SSD means Solid State Drive that is computer drive that stores data.

At this time on kinds of SSD drives possible define following categories:

Category 1 - SSD1 – Read AL” 130 Mb/sec, Write AL” 80 Mb/sec
Category 2 - SSD2 – Read AL” 240 Mb/sec, Write AL” 160 Mb/sec
Category 3 - SSD3 – Read AL” 320 Mb/sec, Write AL” 280 Mb/sec
Category 4 - SSD4 – Read AL” 480 Mb/sec, Write AL” 380 Mb/sec

*Average Latency


2. Higher IOPS and better performance.

Due to absence of rotation accompanied to consistent search of blocks and cylinders SSD provides much better IOPS vs regular hard drive.

All these delivers greater system responsiveness that is very important at time of work with large volumes of data, such as databases, audio and video files, large graphics, etc. For an example use of SSD drive delivers:

Faster SSD provides even better performance.


3. Increase of productivity.

Each SSD saves work time that priced accordingly. General research shows that use of SSD saves about 1 working hour per month. If count wage in amount of $25 per hour each SSD can save more then $300 annually.

Lower interruption time. Slow computer speed causes often in-work interruptions. Average user of SSD interrupts 10 times less vs regular hard drive user.


4. Better reliability and ruggedness.

SSD consist much better ruggedness and overall reliability.

Regular hard drive use time is about 20,000 – 30,000 working hours. Regular SSD designed to work for about 1,000,000 working hours.

Two main cause brakes conventional regular drive: i) damage of drive plate surface ii) damage of magnetic heads sliding axle. Hens, due to absence of moving parts SSD better withstand to hard vibration and unexpected drops.

No need to use ThinkVantage Airbag Protection (with gravity sensor) during SSD drive in use.


5. Lower power consumption

SSD saves power that is important for mobile and data center operations.


Each regular drive installed in data center uses from 15 ro 25 Wt of energy. Each SSD drive uses from 0.6 to 0.8 Wt. That is more then 19 times less power. Means each hard drive uses 131 kWt annually vs 7 kWt for SSD. If energy priced $0.1 per 1 Kwt it allows to save $12.4 annually for each SSD drive installed in data center environment.

For mobile operations use of SSD drives also saves power and prolongs battery life. Regular laptop drive uses from 1.5 to 2.5 Wt of energy. SSD drive uses from 0.6 to 0.8 Wt. Means mobile device would work for about 15% longer and saves from $10 to $20 at time of battery purchase.


6.Security

SSD provides extensive data security possibilities. With encrypted access to data accompanied by OPAL FDO capabilities.

Unlike regular magnetic drive data stored on SSD in electronic form and access to its segments provides built-in controller with encrypted security mechanisms.


7. Other considerations.

Use of SSD significantly lowers waste of work time.

It is not always necessary to look for expensive large size drive at start. First level SSD1 would do its job.

Utilization of SSD brings immediate financial savings and provides better system responsiveness with greater computer experience.
