SSD stands for Solid State Drive, it is a data storage device that uses solid-state flash memory to store persistent user data.
As a more contemporary alternative to traditional rotating disk hard drives (HDDs), an SSD has been designed from the bottom up to provide more benefits for computing devices that need fast and safe access to data, with faster read and write speeds and lower latencies than the spinning/platter-based HDD.
An SSD provides a significant performance improvement over traditional hard drives whether it is in a PC or in a notebook computer.
One such example of this improvement is provided by Samsung’s 840 Evo line of 2.5-inch SSDs that has a SATA III interface and offers better benchmark scores than any of the leading hard drive manufacturers (Seagate, Western Digital and Hitachi).
SSDs consist of non-volatile memory chips like those found on USB flash drives. The technology makes use of an internal data bus to move data between the controller device and the memory chips, while a power supply unit ensures that the data doesn’t get lost when there is a sudden device power-down.
SSDs have no mechanical components and so they are immune to physical shock and offer higher reliability compared to hard drives.
They also provide improved performance by using lower latency random access memory (RAM).
The downside of using SSDs is that they are more expensive compared to HDDs. If you are tight on your budget, it may be better to go with a high-capacity HDD at a lower price. However, for the long term, the cost per gigabyte of an SSD is still much cheaper than its HDD counterpart.
The performance benefit of having an SSD is well worth the initial investment and should be considered by anyone looking to upgrade their existing computer or buy a new one.
Why SSDs improve Computer performance?
What you have just noticed is one of the key advantages of Solid State Drives over traditional spinning hard drives – random access performance.
As compared to a mechanical hard disk drive, where the head needs to move from track 0 to track N for every IO request, an SSD can process multiple requests simultaneously due to its electronic interface being much faster than what a physical actuator plus moving parts can ever achieve.
This does not only give SSDs an edge in terms of random access times – as they are nearly as fast as reading from/writing into RAM – but also allows betterization capabilities, which gives them the ability to do at least some prefetching of data into cache, in order to reduce future access times.
There are many ways how operating systems take advantage of the inherent random access capabilities of SSDs under different workloads.
Different OSes employ different techniques, but in general terms when dealing with IOs which are mostly read requests – as is the case in Windows 7 for example – it is very likely that most/all pending requests can be satisfied from internal caches without touching the physical drive. Since there are no moving parts and regardless of its current position on disk, an arriving IO request can be serviced immediately.
What Does SSD do for gaming?
SSD has no moving parts that could cause them to fail because there are no moving parts, ssd is silent when running and ssd can also read data faster than hard disks. ssd also uses less electricity than regular hard disks.
SSD works by taking short bursts of memory from random locations on its chips and feeding them into RAM. SSD is very fast because SSD accesses data that SSD needs through short bursts of memory, SSD does not need to move its heads like a hard disk which makes SSD considerably faster than regular hard disks. SSD is the future of computing and will be the primary storage medium used in computers in the next few years.
SSD also comes with many benefits like silent operation SSD makes no noise, SSD uses less electricity so you save money on your electric bill because ssd does not need as much power as a regular HDD, SSD is faster than conventional hdds so your computer boots up faster and programs load faster too.
