That is particularly true for storage, as modern blockbuster games constantly load and write files (e.g. Gaming: Gaming computers have always pressed the limits of current computing technology, justifying relatively expensive equipment for the benefit of gaming performance. SSDs have specific benefits in the following areas:Д«usiness: Companies working with huge amounts of data (such as programming environments or data analysis) often rely on SSDs, as access times and file-transfer speeds are critical. But they have since become an accepted option - or even the default choice - in lower-cost mainstream laptops and PCs. SSD adoption began in high-performance technology areas and in enthusiastsвЂ™ PCs, where the drivesвЂ™ extremely low access times and high throughput justified the higher cost. Among our own Avast users, a vast majority still have old-school mechanical drives.

Shipments of SSDs are not expected to overtake HDDs until 2021. Note that the era of traditional hard disk drives is far from over. SSD access times are thus measured in nanoseconds. ThereвЂ™s no waiting for a read/write head to find the information it needs.

The controller of an SSD has the exact address of the blocks, so that when your PC requests a file it is (almost) instantly available. Each grid (also called blocks) can store between 256 KB and 4MB. Instead of a magnetic platter, files are saved on a grid of NAND flash cells. The memory chips on an SSD are comparable to random access memory (RAM). It wouldnвЂ™t be until the late 2000s that SSDs would start to become more reliable and to provide decades of continuous usage at acceptable access speeds. However, the lifespan and size were still an issue: An SSD had a lifespan of roughly 10 years. In the early 1990s, hardware innovations caused SSD prices to drop. SSD technology was used occasionally in the military and aerospace sectors, but it wouldnвЂ™t be used in consumer devices until the 1990s. However, the technology was extremely expensive, and the storage capacity was small (2MB-20MBs) compared to the ludicrous 5-digit prices. They use a simple memory chip called NAND flash memory, which has no moving parts and near-instant access times.Д®arly experiments with SSD-like technology started in the 1950s, and by the 1970s and 1980s they were being used in high-end supercomputers. The new solid-state drives work completely differently.
