SSD: guide to complete understanding and effective application

Modern devices compete with each other in terms of applicability and memory. Thus, any large electronics manufacturer, such as laptops, tablets or smartphones, makes sure that, when launching a new gadget model, even if it is from the same series, it comes with a series of improvements and additions. You can almost always find additional memory, and devices support more and more data.

At the same time, it is very important for a modern device to have as much storage capacity as possible, as through development it increases its applicability and fulfills more and more functions.

Although methods have emerged to store data online, which do not affect a device’s memory, the most secure option is still the drive installed on a device, because online security is still inferior to that of the software itself installed on a device. .

Among all these, SSD memory has garnered particular importance and is included in almost all modern devices. Also, manufacturers offer larger and larger SSD memory with each new device model.

Therefore, it is important for users to know what SSD memory is, in order to understand how to use it.

1. What is SSD memory?

To understand what an SSD is, users must first understand what is the definition of this type of memory, why it is important, and how it works.

The notion of SSD is an acronym for Solid-State Drive, which means that SSD memory is a hardware component.

Being a new generation of storage method, there are SSDs that replace external hard drives. Instead, it is very important not to confuse SSD storage with web hosting, this being a different component with a different role applicable in the online environment.

2. Definition of SSD

Regardless of whether it is a laptop or a smartphone, SSD storage can be defined in the same way in any case.

The simplest definition of SSD says that this is a storage device that uses integrated circuit assemblies to continuously store data, using, most of the time, flash memory and functioning as an external memory in the technical assembly of a device. . Also known as a solid-state drive and solid-state disk, although SSDs do not have physical spinning disks or the moving read-write heads used in hard drives or floppy disks.

This definition can be found in various sources that refer to this topic, although it can appear in various forms.

3. What is the importance of SSD memory?

SSD memory for a computer, laptop, or smartphone is important for a number of reasons.

First, it allows the system to start up almost instantly and applications to run without interruption. In general, problems with available memory make processing difficult.

Also, the fact that a device charges easily also favors the way the cooler works, since you will no longer be overloaded to keep the temperature of a device at a decent level. When a device processes slowly, it gets very hot and the cooler needs to prevent overheating.

Another significant benefit is the fact that the SSD memory, being a hardware component, can be used both connected to the device and disconnected, only for storage, so there is no need to access the data.

4. How does SSD memory work?

The SSD uses semiconductor chips to store data. The chips used in SSDs offer non-volatile memory, which means that data remains stored even when not connected to a power source.

Also, SSDs cannot store data other than the existing ones, they need to be removed in the first phase.

Also, SSDs actually have more available space than mentioned in the package description at the time of purchase. This additional memory is called over-provisioning, and it represents memory used for internal tasks, not for the operating system.

In the last phase, the data is organized so that the erase cycles are evenly distributed across all sections of the device.

5. Advantages and disadvantages of SSD memory

To understand everything about SSD, it is necessary to mention both the advantages and disadvantages of this type of memory.

Taking into account that it is a different memory from the device and can be separated from the laptop or smartphone, it can be used or not, depending on how it affects this device or how necessary it is for the user.

There is also the possibility that the SSD is indicated for certain devices, and others work better without it. It all depends on how a gadget’s internal memory is managed and the type of data that requires storage.

6. The advantages of SSD memory

In general, SSDs have an access speed of 35 to 100 microseconds, making them 25 to 100 times faster than an HDD. This makes the SSD more reliable than the HDD because it uses less power, has shorter processing times, increases device battery life, and can process file transfers much faster.

From a physical point of view, it is more resistant to various forms of impact, because it does not have additional moving parts. This makes it more resistant to data loss caused by impacts.

7. Disadvantages of SSD memory

Unfortunately, there are also a number of disadvantages.

First of all, the price of an SSD memory is higher than that of hard drives. Also, most of today’s SSDs have smaller storage capacities than hard drives.

Currently, SSDs have a limited storage capacity, in most cases it is 128 GB. A higher storage capacity means an increase in price.

Another downside to SSDs is their limited availability. Hard drives continue to dominate the market and are much easier to find. However, the electronics market is increasingly focusing on more compact devices, which means that the availability of SSDs is increasing.

8. For which devices is SSD memory most important?

SSD memory can be integrated into almost all types of electronic devices, regardless of whether it is a smartphone, laptop or tablet.

The importance of the SSD depends on how it is used and its purpose. Thus, it can be said that it is recommended for devices with less space, but that are used a lot and store data frequently. The best example is the smartphone, which is used constantly and stores information and documents every day. Compared to a laptop, a smartphone leaves the factory with less memory.

Instead, SSD memory is just as important to keep documents on a separate device, so they don’t take up main memory.

9. Types of SSD memory

There are several types of SSD.

Therefore, when users search for SSDs, they will see several different terms, such as mSATA or PCIe.

Each one represents a specific interface, which has an essential role in connecting an SSD memory to the electronic device system.

Also, SSDs come in various storage capacities, from around 32GB up to 5TB. Instead, any type of SSD memory should not be confused with an external HDD. The latter is larger and can fulfill other functions within the system of a device.

10. SSD-PCIe

PCI Express (PCIe) is typically used to connect graphics cards, network cards, or other high-performance peripherals. This interface offers high bandwidth and low latency, making it the ideal choice when you need fast communication between SSD and CPU or RAM. SSDs using this type of connection are based on the Nonvolatile Memory Express (NVMe) standard, which offers higher input-output speed per second (IOPS) and latency than SATA, the other connection. NVMe can provide throughput of up to 16 GB per second.


SATA is an acronym for Serial Advanced Technology Attachment (SATA). This is an older interface and was designed specifically for storage, with speeds up to 6GB per second, or about 600MB per second. SATA is used less and less due to the advent of NVME, which is much faster. However, older PCs or laptops with a good HDD can still benefit from upgrading to SATA-based SSD memory.

12. What kind of SSD memory is better? It can be said that the SSD memory that uses the PCI Express interface is better, because it offers faster execution speed. However, the SATA interface can still be used with certain devices.


Therefore, it is important to understand how SSD memory works in order to know how to manage it and do it effectively.
