What is an SSD Disk and Why is it Different from a Normal Hard

by The Digital Trendz

Lately we hear a lot about SSD disk, in fact, for some years many people have already started to install them in the computer. However, the question arises for those less accustomed to new technologies: what are SSD disks? In practice, these are “special” hard drives, which use flash memory compared to classic hard drives. When it derives to Solid State Drives (SSD stands for Solid State Drive), many compare these tools to hard drives.

It is true that these are two alternative solutions to each other, but we should not think of SSDs as an evolution of hard drives, but as a new technology that has radically changed the management of internal memory. Hard drives have been targeting increasing storage capacity for years, while solid state drives are targeting security, speed, and in particular improving the performance of the machine on which they are installed. Today, SSDs are increasingly present in modern laptops, however, it is important to understand what features you need to evaluate to determine. And What is the best solution to meet your needs.

What Differences SSD and Hard Disk

What are the structural differences between an SSD and a hard drive? Solid state drives, such as Kingston SSD A400, unlike hard drives, do not have mechanical parts like heads or spindle platters. Without mechanical components, it is much more difficult for the SSD to fail due to damage or drops. The removal of mechanical parts was made possible by the use of SATA (Serial Advanced Technology Attachment) headers, compatible with virtually any motherboard. When working with collectors at the RAM level, performance improves, but SSDs have a limit, that is, a very precise period of time. On average, the lifespan of solid state drives is 5 to 6 years. Although it all depends on the write cycles.

SSD Development and Technical Evolutions

Solid state drive interfaces have undergone developments and evolutions over the years. At the beginning, for example, they were used only in laptops, while in recent times they are beginning to be adopted. Also in stationary devices and next-generation ultra-thin laptops. This success is due to a host of new features and faster than ever data transfer speeds. On the market there are SSDs with SATA III interface and hard disk, with SAS or HDD interface, or with SATA III or Serial ATA-600 interface.

What option should you buy? As always, on a technological level, before buying a device it is necessary to analyze its needs. If storage is our first need, especially above 1TB, a hard drive is worth buying. If, on the contrary, we are looking for the writing speed and the best performance of the machine, the recommended option is solid state drives. Here are some helpful tips for choosing an SSD for your PC.

How to Choose an SSD Drive

Before buying a PC, or buying an SSD disk to install in the laptop, it is important to understand how to evaluate the technical characteristics of this hardware component. First of all, you want to consider its compatibility with your laptop or PC. Analyzing whether the dimensions allow for seamless integration. Today, most M.2 and SATA memories easily fit standard sizes. Which for today’s PCs range from 5 to 9 millimeters in height and 2.5 inches in size.

In the other hand, it is essential to look at the capacity of the SSD, depending on which the medium can store a more or less large amount of data. In the market you can find very different models, with a storage capacity between 64GB and 4TB, so it is essential to choose a product suitable for your personal needs. Mid-range SSDs offer 500GB of space; otherwise with the high-end models you get 1 or 2 TB without any problem.

Equally essencial is the number of write cycles, that is. How many times the storage space can be used before the media is no longer available. Then before it stops working and ensures optimal performance. On average, modern SSDs offer 3-5 thousand cycles, however the presence of a cleaning system is essential. This device, in fact, allows to increase the duration of the memory. Thanks to the possibility of automatically deleting junk files. An effective solution especially when combined with a TRIM function.
