Solid State Drives (SSD), originally developed in the years 1980, have until now because the cost is largely focused on military applications and companies in search of better performance for large databases and other such demanding applications. However, cost SSD now moved to the point of beginning to general consumer electronics market to penetrate. Many of us were already using 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 platters and moving arm, an SSD has no moving parts. No power is required to provide data that can hold up to 10 years to preserve.
Reliability
The lack of mechanical parts supplies SSD with greater robustness in the direction of shock or vibration, extreme temperatures and humidity, which made them popular for military applications (MIL-STD-810F military standard). Solid state memory can survive drops to resist and survive water fields. I can personally testify that a solid state memory game will survive the washing machine to work fine. Robustness is a part of the reason SSD can be found in mobile consumer electronics applications.
Speed
Speed access to data is a frequently raised benefit of SSD. Typical access times for SSD may be 35-105 micro-seconds compared to 5000-10000 micro-seconds for a conventional HDD. However, recent research by IDC indicates that the gap between the performance of 7200 RPM 2.5-inch drives and systems with SSD is smaller than expected. The performance of the whole system was important factor in the gap is smaller than expected rather than the SSD. IDC observed that the system redesigns will be necessary for PCs to the full benefits of a SSD drive - something to remember.
Heat and Power
Less waste heat generation and lower power consumption are two benefits of SSDs. Less energy use translates into smaller and smaller power supplies energy bills. Reduced heat load requires less cooling, and in some cases eliminating the need for cooling fans. Lower heat and electricity demands are ideal for mobile consumer electronics applications.
A recently developed wireless inductive coupling SSD technology promises significant internal wiring requirements and reduce energy consumption by about 50 percent.
Life
A conventional HDD computer usually has a lifespan of more than 3 years. All evidence points to the current excess of those securities and derivatives. Intel claims 5 years 'useful life' for their X-18M SSD is based on a large load of data writing 100GB/day. Metron prepared for a 5 years warranty on their SSD PRO 7000 series offer.
A prominent SSD manufacturer, BiTMICRO recently estimated 12.9 years of life for an SSD in a database application. Its lifetime was estimated, despite the conservative assumptions of a relatively rigorous workload and no application for renewal of life as caching strategies and wear leveling. Wear leveling is achieved by balancing algorithms that drive the block write totals monitor and can greatly extend the operational life of an SSD.
STORAGEsearch.com recent estimate (computational) that the life of SSD in enterprise server applications is of the order of 50 years.
Cost and capacity - the determining factors
Cost and capacity are the two areas where conventional SSD HDD may exceed available in the market today. Things are quickly changing.
Capacity
At present the maximum magnetic HDD available capacity is 2 TB (2 TB Western Digital Caviar Green WD). Hitachi aims to 4 TB hard drives using new technologies to produce nanometer recording 2011.
The highest capacity SSD (more cost) is the 1TB Nitro by pure Pure Silicon Silicon Inc. have been able to 15.4GB per cubic centimeter a great achievement. Average Time to Failure (MTTF) about 2 million hours (228 years).
Cost
Currently, consumers will still pay a relatively high premium for an SSD instead of HDD with the price difference sometimes $ 1,000. This situation is changing rapidly but with research firm IDC reported that costs decrease by an impressive 40 to 50 percent per year and the price right can be achieved in 2011.
Current market for SSD
Despite the advantages of robustness, low power and higher speeds combined with a fairly large capacity, price seems squashed a significant uptake of SSD, especially in the consumer computing market. With the current price premiums This is not surprising. Fortunately, 2011 is not far away.
Many major PC manufacturers are already testing the market with SSD equipped computing offerings including;
- Dell Latitude D430 Notebook (32GB SanDisk 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)
