How To Buy The Right SSD? If you want to improve the performance of your desktop or laptop, SSD could be a good solution. It could replace your current hard drive or support it depending on your machine configuration. Why opt for this technology and how to choose the best model? You will find the answers to these questions in this guide.
What is Solid State Drive?
The Solid State Drive or SSD is a state-of-the-art drive. It is characterized by its speed, delicacy, lightness, and silence. Working like a conventional hard drive, it can store your device’s operating system as well as all the programs you use frequently. In this way, your PC will take less time to start Windows, scan files with an antivirus, run a heavy program, or shut down.
The capacity of an SSD varies from model to model. It is measured in Gigabytes – GB, it is quite special because it measures a maximum of 2.5 inches and does not have any mechanical components. This is the internal NAND flash memory that makes it work. It also contains a driver that communicates with the operating system and firmware that processes files, among other things, when writing.

Four brands currently dominate the SSD market: Sandforce, Intel, Indilinx, and Marvel. And there are two main families:
- SATA SSDs in M.2, mSATA or 2.5 inches;
- PCIe SSDs in M.2 or U.2.
Advantages of SSD
With an SSD, you can expect a high transfer rate. The latter can go up to 550 MB/second for reading and 510 MB/second for writing. Energy-efficient, its power consumption is around 3 watts when it is working. Its access times are almost instantaneous, that is, 0.1 milliseconds. Very reliable, it is safe from possible breakdowns. The absence of mechanical parts makes it silent.
The different categories of memory
There are currently three kinds of SSDs on the market.
1. The Single Level Cell – SLC NAND
It is a model that is both fast and reliable. The use of this SSD disk is strongly recommended in the professional environment. It costs more compared to the other two models.
2. The Multi-Level Cell – MLC NAND
The standard model is the most popular memory on the market. Durable, it is able to withstand a high number of write/read cycles. It is recommended for normal use.
3. The Triple Level Cell – TLC NAND
It is the cheapest solid-state drive. Its performance is also lower than that of the other two and its lifespan is limited. Its flash memory cell has 3 bits.
How To Buy The Right SSD – The criteria for choosing an SSD drive
Learn all the criteria to consider before acquiring an SSD drive.
Its storage capacity
The capacity of an SSD is closely related to its performance. Also, your gigabyte of data is expensive. It is for this reason that you will have to choose a model with 60 GB to 1 TB at the time of purchase. This is the range that offers the best value for money.
If you want to have more storage capacity, you can combine your SSD with a classic hard drive and achieve exceptional performance.
Its writing and reading speed
When SSD speed is high, so are writing and reading. Please note, however, that the figures provided by manufacturers are not always accurate. You should expect more or less slow performance when using it.
It is with its controller that you can appreciate the quality of an SSD. This is a very important component because it is used to record or decode your data on this disk. It can also repair or fix any errors that you may come across while using your PC.
You should also consider how many IOPS you have. The more there are, the faster and more efficient the SSD will be.
The 2.5-inch solid-state drive is the most popular on the market. If you plan to install it on your desktop computer whose available slot is 3.5-inch, you need to buy an adapter.
As for the thickness of an SSD, the 7mm model is perfectly suited for laptops. There are also 9.5mm ones that can be installed on desktop computers.
Some manufacturers offer a longer or shorter warranty for their SSDs. Its lifespan varies from model to model and can range from 360TB to 1440TB. This is the amount of data you can write to them before the drive runs out. The greater its capacity, the greater the guarantee.
Difference Between SSD and HDD
There are some notable differences between an SSD and an HDD model.
The SSD has various sizes with a maximum of 2.5 inches. A hard drive comes in two versions: a 2.5-inch for laptops and a 3.5-inch for desktops.
The access time is relatively low for an SSD, i.e. 0.1 ms compared to 7 ms for an HDD. The maximum transfer speed of the former exceeds 500 MB/second while that of the latter is capped at 200 MB/second.
The HDD has a platter where the data will be written through mechanical parts. An SSD contains only NAND flash memory. The link between it and the operating system is provided by a driver.
