A hard disk is an integral part of any system, as it is responsible for the long-term storage of information, including the operating system. However, it was replaced by solid-state drives. So what are the benefits of a solid state drive?
What is an SSD?
The name "solid state drive" means that this type of storage does not have mechanical parts, unlike an ordinary "hard drive". The appearance is confirmed by the fact that only a microcircuit and memory chips participate in the creation of the drive.
One impressive difference is the SSD - an incredible read and write speed that far surpasses the hard drive. If the hard drive needs time to find the necessary information, then the SSD instantly answers the request.
The advantage is also in the complete absence of rotating parts, which ensures quieter operation. This setting has a positive effect on the lifetime of the SSD. During operation, the solid state drive maintains an optimal temperature level when the hard drive has a chance of overheating without additional cooling.
The shockproof properties of the hard drive are significantly inferior to solid state drives, since the presence of mechanical parts contributes to their damage.
The only drawback is the price. The more the SSD contains, the higher its cost. Many users prefer the joint work of two types of drives, since it is optimal for the system to use high-speed devices, and store information on the hard drive.
Operation restriction
SSD, unlike a mechanical counterpart, has some limitations. Firstly, the maximum amount of memory only reached the threshold of two terabytes. The price of such a "solid" reaches 60 thousand rubles. Expensive pleasure, therefore, as a permanent storage, the benefit is on the side of mechanics. Although you can use a less expensive solid state external hard drive 1 TB.
Secondly, the SSD has a limit on the number of entries. Manufacturers indicate the number of permissible overwrites on the disk, after which each may be the last. After the boundary of the last record is overcome, the manufacturer’s warranty ceases to apply.
Description of external storage
Like hard drives, external solid state drives have different models. There are three essential qualities that an SSD has - reliability, speed, and quiet operation. The only obstacle that makes it possible for Winchesters to lose is the threshold of two terabytes.
Some users agree that owning a regular USB flash drive is much more practical than using an expensive external SSD hard drive. The only significant counterbalance in this confrontation is speed.
It is this parameter that even allows you to run games from an external solid state hard drive. Its data transfer rate reaches almost 500 megabytes per second. At such a speed, copying data will not take as much time as transferring files from a USB flash drive or an ordinary hard drive.
Samsung T1 Portable
The first manufacturers of external hard drives in TB were Samsung manufacturers. Description of this model should start with the main thing - speed. Its read / write parameter reaches up to 450 megabytes per second. Connection to external storage is carried out using the USB 3.0 port. This port is present on almost all modern devices.
Unlike many representatives of SSD, this model does not have 128-bit data encryption, but 256-bit. This fact allows you to verify the safety of information on the device. There is also a built-in memory controller. In appearance, only one thing can be said - a stylish design.
Transcend thunderbolt
This company has long established itself in the market of portable data storage devices. Its solid state external hard drive has a memory capacity of 256 gigabytes.
An unusual property that this drive possesses is work in the HFS + format. It is also worth noting the connection method - this is the Thunderbolt interface. Thanks to him, the speed of data exchange is made with incredible performance. Both of these options allow you to use this device to work with macbooks. However, it can be operated with ordinary laptops and computers.
Toshiba Canvio AeroMobile
Toshiba is well known as a company that produces high-quality hard drives, so the release of its SSD labeling was not long in coming.
Unlike previous models, this drive has only 128 gigabytes of memory, but the price is much lower. Data is transmitted at a speed of 380 megabytes per second, and the connection is made using the USB 3.0 interface.
The uniqueness of this solid-state drive is that it is able to provide wireless communications. This device is perfect for corporate workers, as it communicates with eight devices at the same time. This parameter allows you to cope with the transfer of data to multiple computers at once.
SSD Samsung T5
Another stylish option from Samsung that supports USB 3.1. This 2 TB solid-state external hard drive has a black metal case, and its dimensions allow you to sit even in a women's handbag.
Encryption is performed in 256-bit mode, which ensures high reliability of data storage. The kit comes with two types of cables that allow you to use the device with connectors of the old and new generation. Read / write speed reaches 500 megabytes per second, which is an important indicator in the operation of external portable storage.
