Solid state is an electrical term that refers to electronic circuitry that is built entirely out of semiconductors. The term was originally used to define those electronics such as a transistor radio that used semiconductors rather than vacuum tubes in its construction. Most all electronics that we have today are built around semiconductors and chips. In terms of a SSD, it refers to the fact that the primary storage medium is through semiconductors rather than a magnetic media such as a hard drive. Now, you might say that this type of storage already exists in the form of flash memory drives that plug into the USB port. This is partially true as solid state drives and USB flash drives both use the same type of non-volatile memory chips that retain their information even when they have no power. The difference is in the form factor and capacity of the drives. So how exactly do they do this? Well, an SSD on the outside looks almost no different than a traditional hard drive. This design is to allow the SSD drive to put in a notebook or desktop computer in place of a hard drive. To do this, it needs to have the standard dimension as a 1.8, 2.5 or 3.5-inch hard drive. Why Solid State Drive? Solid state drives have several advantages over the magnetic hard drives. The majority of this comes from the fact that the drive does not have any moving parts. While a traditional drive has drive motors to spin up the magnetic platters and the drive heads, all the storage on a solid state drive is handled by flash memory chips. This provides three distinct advantages: Most Durable and Reliable Reliability is one of the most important key factors for portable drives. Hard drive platters are very fragile and sensitive materials. Even small jarring movements from an impact can cause the drive to be completely unreadable. Since the SSD stores all its data in memory chips, there are fewer moving parts to be damaged in any sort of impact. Solid state drives (SSDs) are ideal for users who rely heavily on long-lasting drives and require the fastest response time from their storage devices. With no moving parts, SSDs can withstand extreme temperature ranges, and conditions of vibration and shock in transit. SSD VS HDD Advantages Faster startup (as no spin-up is required). Faster random I/O (compared to hard disk drives). Extremely low read and write latency (seek) times, orders of magnitude faster than the best current hard disks drives. Faster boot and application launch time when hard disk seeks are the limiting factor. In some cases, somewhat longer lifetime Flash storage typically has a data lifetime on the order of 10 years before degradation. If data is periodically refreshed, it can store data indefinitely. Fewer moving parts. SSDs consume up to 50 percent less power than rotating HDDs. SSDs speed up operating system boot and application launch/runtime by up to 2 times. SSDs maintain fixed performance that does not deteriorate over time as the media is filled. Flash is noise-free, enhancing the user experience. Disadvantages The cost of the SSD is extremely relatively to HDD.
