Solid State Disk or Solid State Drive is a relatively new type of storage device based on the principles of conventional flash memory. This type of memory is non-volatile, works fast enough and is not cleared when the power is turned off. Unlike conventional hard drives, these devices are compact and lightweight, easy to operate, operate without extraneous noise and overheating. SSD drives are used in home computers and professional equipment. The features of choosing the best solid state drives, their technical characteristics, as well as advantages and disadvantages are described in this article.

SSD drives have already become a common attribute of personal computers and laptops. There are several types of such devices. First of all, it is worth dividing all devices by purpose:
In addition, there are different options for solid state drives depending on:
The most common connection types are SATA (older and slower) and PCIe (modern and faster). SATA devices are typically 2.5 ”or mSATA form factor. Drives with PCI connection are usually made in the form of a miniature board with soldered elements (M2 connector).
There are three types of solid state drive memory:
They differ in the number of bits in a cell: SLC has one bit, MLC has two bits, TLC has three bits. This feature determines the maximum number of rewriting cycles, as well as the speed of the device. Increasing the number of bits negatively affects the performance and longevity of the drive.
What to look for when choosing a solid state drive? The question is very complex, therefore, before buying, you need to decide on a set of certain characteristics of a new device. The selection criteria are quite diverse: from basic technical parameters to ergonomics and design. Let's try to disassemble each of them:
Manufacturers offer various options - from 60 GB to 2 TB. The optimal volume is determined by the purpose of the device: devices with a capacity of up to 256 GB are used to install the operating system and various programs, disks up to 512 GB are suitable for storing a large amount of media files, larger drives are used by gamers, developers, etc. You need to know that Low capacity SSDs are applicable if you have a basic HDD in the assembly. Otherwise, you need to lay the volume of the solid-state drive at least 1-2 TB.
Directly affects the performance of the device. The most common variant is with TLC memory. They are not the most durable, while they are many times faster than standard hard drives in performance. Multi-level MLC cells are characterized by high service life and high speed. This type of memory is most often used by fans of games and multimedia viewing.SLC-based devices offer unique durability and performance. Such discs are used to solve professional problems.
The dimensions of the device depend on the system into which it will be integrated. For regular personal computers and laptops, the inexpensive 2.5 ”form factor options are suitable. In the case of ultra-thin technology, it is necessary to use miniature solutions with dimensions similar to PCI cards.
SSD performance is determined by the type of memory used. In this case, when choosing a device, you must be guided by the following: if you plan to use it only as a storage, then first of all you need to pay attention to the write speed. If you plan to use the disk to run software and games, the main thing is the read speed.
First of all, it is necessary to highlight the TRIM function - the so-called cleaning the disk from garbage. It will help improve performance and extend the life of your device. It will be very useful to have the SMART function - a system for analyzing and monitoring the state of the device. This technology will promptly identify problems and prevent the loss of important data.
There are several ways to connect solid state drives to your computer. It is the type of interface that determines the optimal throughput of the device. For example, SATA provides processing speed of 600 Mb / s, and the PCI 3.0 connection type is 4-6 times faster. The latter option is the most expensive, so it is suitable primarily for game lovers and professional developers.
Most SSD drives can easily withstand writing up to 1 petabyte of information, and newer models are twice as large. In addition, there are a number of ways that can extend the life of the device: do not defragment the disk, leave at least 20-25% of the device's memory free, keep old files for a long time, etc.
One of the most important parameters. The durability and stability of work depends primarily on the manufacturing company. You should not chase cheapness, preferring cheap Chinese goods from aliexpress. It is necessary to make a choice in favor of companies that have already proven themselves from the best side, developers of the most advanced technologies in the field of SSD. The rating of the best manufacturers of quality solid state drives, based on feedback from real buyers, presented below will help you decide on the purchase of the necessary device.
