Question: What is an SSD (Solid State Drive)?
A solid-state drive (SSD) is a type of computer data storage that emulates a HDD [Hard Disk Drive], however it uses flash memory instead of spinning disks to store data. With no moving parts, SSD are inherently less fragile than hard disks, and therefore are also silent (unless a cooling fan is used). As there are no mechanical delays, they benefit with low access times and lower latency. SSD is a data storage device that uses solid-state memory to store persistent data. Some SSD’s use either SRAM or DRAM instead of Flash memory [non-volatile computer memory } and are often called RAM-drives.
SSD are available in standard form factors of, 1.8-inch, 2.5-inch, and 3.5-inch. Since they have no moving parts they can withstand extreme shock, vibration, temperature, altitude and harsh environmental conditions while operating without compromising on data integrity. Standard models operate in temperatures of 0 - 70° C. and special industrial models can withstand operating temperatures of -40 - 85° C.
[b]Question: How do I use a SSD?[/b]
Like a traditional hard disk drive, it can be installed into computer as usual and then formated and installed with operating system like Microsoft Windows, Linux, Mac OSX and others.
Question: Why SSD?
Compared to a HDD, a SSD can accelerate performance of high availability applications and significantly reduce total cost of ownership because they are:
* Faster. With reads speeds up to 120 MB per second and write speeds up to 90 MB per second, SSD’s drastically improve HDD performance.
* Longer lasting. An intelligent algorithm ensures advanced wear-leveling and even usage of the entire flash memory region.
* More reliable. SSD's have a mean time between failures (MTBF) of one million hours. Plus, it provides enhanced data integrity due to its 7-bit error correction code (ECC) and advanced bad block management.
* More robust. With no moving parts, an SSD is more tolerant of extreme shocks, vibrations and temperatures.
* More power efficient. Due to its solid state, an SSD uses less power and therefore emits less heat, reducing data center management costs.
* Noiseless. Reduces ambient noise in data centers and offices.
* More Portable. SSD's weight is significantly less, making systems much more portable and lighter. This opens the way for new classes of ultra-portable laptop and handheld computers, and new applications
