Solid State Drives (SSD), originally developed in the 1980s, have to date, due to cost, largely focused on military applications and enterprises looking for improved performance for large databases and other such demanding applications. Yet now SSD cost down to the point of beginning to general consumer electronics market penetration. Many of us actually use all of SSD technology in our iPhone or iPod.

A SSD is based on solid state semiconductor technology similar to the familiar Secure Digital (SD) card in a camera. Unlike the magnetic hard disk drive (HDD) with rotating discs and moving arm, an SSD has no moving parts. No power is required to retain data that can persist up to 10 years.

Reliability

The absence of mechanical parts makes SSDs with greater strength to shock or vibration, extreme temperatures and humidity them popular for military applications (MIL-STD-810F military standard). Solid state memory can drops survive, resist magnetic fields and water survival. I can personally confirm that a solid state memory game will survive the washing machine works fine. Robustness is a part of the reason SSD can be found in the consumer mobile electronics applications.

Speed

Speed of access to data is often a raised benefit of SSD. Typical access times for SSD is 35 to 105 micro-seconds over 5000 to 10,000 micro-seconds for a conventional HDD. However, recent research by IDC indicated that the performance between 7200-rpm 2.5-inch drives and systems with SSD is smaller than expected. The performance of the entire system was the key factor to the gap smaller than expected rather than just the SSD. IDC have noted that system redesigns will be necessary for PCs to the full benefits of a SSD drive to get - something to remember.

Heat and Power

Less waste heat generation and lower power consumption are two advantages of SSD. Less energy use translates into lower power and smaller energy bills. Reduced heat load requires less cooling and in some cases eliminating the need for fans. Lower heat and electricity requirements are ideal for mobile consumer electronics applications.

A newly developed wireless inductive coupling technology promises a substantial SSD's internal wiring requirements and energy reduce by about 50 percent.

Lifetime

A typical conventional computer HDD has a lifetime greater than 3 years. All data indicate the current securities and derivatives over this. Intel say 5 years 'useful life' for their X-18M SSD based on a significant burden of writing data 100GB/day. Metron are prepared for a 5 years warranty on their SSD Pro 7000 series offer.

A prominent BiTMICRO SSD manufacturer recently estimated 12.9 years of life for a SSD in a database application. This lifetime was estimated despite the conservative assumptions of a fairly rigorous workload and an application to extend the life strategies such as caching and wear leveling. Wear leveling is achieved by balancing algorithm that the disk block write control totals and may vary operational life of an SSD to expand.

STORAGEsearch.com recently estimated (computational) that the life of the SSD in enterprise server applications was of the order of 50 years.

Costs and Capacity - the decisive factors

Cost and capacity are the two areas may exceed conventional HDD SSD available in the market today. Things change quickly.

Capacity

At present the maximum magnetic HDD 2 TB capacity is available (2TB Western Digital WD Caviar Green). Hitachi 4TB desktop drives targeted at nanometer recording with new technologies to produce by 2011.

The highest capacity SSD (much higher cost) is the 1TB Nitro by pure Pure Silicon Silicon Inc. have been able to an amazing 15.4GB per cubic centimeter reach. Mean Time to Failure (MTTF) is about 2 million hours (228 years).

Costs

Currently, the consumer still pay a relatively high premium for a SSD instead of a HDD with the price difference sometimes reaching $ 1000. This situation is changing rapidly but with research IDC reported that costs decrease with an impressive 40 to 50 percent per year and the price parity can be achieved by 2011.

The current market for SSD

Despite the advantages of robustness, low power consumption and high speeds combined with a fairly large capacity, the price seems crushed a significant uptake of SSD, with particular in the consumer computing market. With the current price premium is not surprising. Fortunately, in 2011 not far away.

Many major PC manufacturers are already testing the market SSD equipped computing offerings including;

Dell Latitude D430 notebook (SanDisk 32GB SSD)
Eee PC S101 (up to 64GB)
Toshiba Portege R500 sub-notebook (up to 128GB)
HP EliteBook 6930p notebook company (SSD optional)
Lenovo S10 mini-notebook (16GB SSD optional)
